Disaster planning for regular folks: level-headed prepping tips

lcamtuf@coredump.cx, Dec 2015, minor updates Jul 2021.

1. Introduction https://lcamtuf.coredump.cx/prep/index-old.shtml

The prepper culture begs to be taken with a grain of salt. In the public
consciousness, its has all the makings of a doomsday cult:
a tribe of unkempt misfits who hoard gold bullion, study herbalism,
and preach about the imminent collapse of our society.

Today, most of us see such worries as absurd. It’s not that life-altering disasters are
rare: every year, we hear about millions of people displaced by wildfires, earthquakes,
hurricanes, or floods. Heck, not a decade goes by without at least one first-class
democracy lapsing into armed conflict or fiscal disarray. But having grown up in a period
of prosperity and calm, we find it difficult to believe that an episode of bad weather or a currency crisis
could upend our lives.

I suspect that we dismiss such hazards not only because they seem surreal, but also because
worrying about them can make one feel helpless and lost. What’s more, we tend to follow the
same instincts to tune out far more pedestrian and avoidable risks. For example,
most of us don’t plan ahead for losing a job, for dealing with a week-long water outage, or
for surviving the night if our home goes up in smoke.

Quite often, our singular strategy for dealing with such dangers is to hope for the
government to bail us out. But no matter if our elected officials prefer to school us with
passages from Milton Friendman or from Thomas Piketty, the hard truth is that no state can provide
a robust safety net for all of life’s likely contingencies; in most places, government-run social
programs are severely deficient in funding, in efficiency, and in scope. Large-scale disasters
pit us against even worse odds. From New Orleans in 2005 to Fukushima in 2011, there are
countless stories of people left behind due to political dysfunction, poorly allocated
resources, or lost paperwork.

The purpose of this guide is to combat this mindset of learned helplessness by
promoting simple, level-headed, personal preparedness techniques that are easy to
implement, don’t cost much, and will probably help cope with whatever life throws our way.
More important, they don’t get in the way of enjoying your everyday life – and instead of
feeding anxieties, they should make it easier to detach from the doom-and-gloom of 24-hour news.

2. Mapping out the unknown https://lcamtuf.coredump.cx/prep/index-old.shtml

Effective preparedness can be simple, but it has to be rooted in an honest and
systematic review of the risks one is likely to face. Plenty of newcomers begin
by shopping for ballistic vests and night vision goggles; they would be better
served by grabbing a fire extinguisher, some bottled water, and then putting the rest of
their money in a rainy-day fund.

To avoid being overwhelmed when trying to enumerate risks, I found that it’s best to focus on
broad outcomes instead of trying to envision every single way for things to go south.
For example, it should not matter if one is laid off because of a downsizing, because
their new boss hates them, or because the coworkers finally catch them stealing paperclips. The
outcome is the same: they are out of a job and urgently need a way to pay the bills.

In the end, a careful examination of our daily routines and their failure modes tends to offer
better payoff than getting bogged down with long-winded hypotheticals. Another common distraction is
the desire to immediately figure out how to respond to all the scenarios we end up dreaming of. Let’s save that for later;
by prematurely focusing on the second half of the problem, we may end up glossing over some of the less tractable scenarios
– or make haphazard assumptions that will cloud our judgment in other ways.

I also believe that to come up with a rational threat model, we need to think of “risk” as a product of
both the probability and the consequences of a given event. By that metric, stubbed toes
and zombie outbreaks are equally uninteresting; one of them has nearly zero significance,
the other, nearly zero odds. The non-recoverable cost of mitigations matters, too. Some expenses
can’t be recouped if a disaster does not come.

What else? Ah, right: the final heuristic I’d recommend is to keep things uncomplicated. There are
popular doomsday predictions that deal with cutting-edge particle physics, god-like computer
hackers, vast government conspiracies, or extraterrestrial messages hidden in pop songs. I suppose
we can’t really rule that stuff out, but historical data suggests that there’s a lot more
merit in worrying about falling off a ladder or getting hit by a car.

With these caveats in mind, let’s go over some canonical scenarios that are worth thinking about.

2.1. Problem space #1: Small-scale events https://lcamtuf.coredump.cx/prep/index-old.shtml

It can be fun to speculate about solar flares and supervolcanoes; it’s far more mind-numbing to
seriously evaluate the consequences of backed up sewage or burst water mains. But in reality,
such unglamorous, small-scale incidents that do not make the news are far more likely to disrupt and reshape
our lives.

Broadly speaking, disastrous outcomes of such humdrum contingencies can be divided into
several groups:

• Insolvency.
  If a person over the age of 40 tells you that they have never lost a job, they are
  pretty lucky (or lying). Yet, the risk is seldom taken seriously; many middle-class,
  single-income families would be in trouble after even a very brief period of unemployment.
  Even in the $100,000+ income bracket, living paycheck-to-paycheck is a common thing.

• Disrupted access to water, food, energy, or transportation.
  Substantial and prolonged outages happen everywhere; many of us will experience
  at least one at some point in our lives. A week without electricity may be just
  inconvenient and scary, especially in a high-rise or
  in a seedy neighborhood. But other services can be more critical:
  even a single hot day without potable water is really bad news.

• Loss of shelter.
  Every year, there are over 350,000 house fires in the United States. Such accidents
  usually aren’t deadly – but if you are unlucky, they can leave you stranded in the middle
  of the night in your PJs, with no documents or credit cards in hand. Insurance can help,
  but even in simple cases, it takes time to get the final payout, and it takes months to
  rebuild.

• Unintentional injury.
  Largely preventable and predictable incidents – such as falls, vehicle collisions, and poisonings –
  account for some 40 million ER visits annually. It can be argued that people are sometimes too
  quick to rush to the hospital, but said incidents also result in about 100,000 US
  deaths every year.

• Intentionally inflicted harm.
  Violent crime is essentially normal almost everywhere in the world.
  In the US in the 90s, your lifetime likelihood of victimization was
  estimated to be around 80%; the odds of suffering criminal injury hovered at 40%. More recent
  research is hard to come by – but scary or even life-threatening encounters remain a very real risk.

• Debilitating illness or death.
  It’s going to get us; maybe next week, maybe in 50 years. We can’t really predict the day,
  but we can understand and meaningfully manage the impact it will have on those who depend on us –
  say, our stay-at-home partners or young kids. Probate cases often drag on for a year or more and
  involve substantial fees; in contrast, setting up your finances correctly may take as little as
  10-15 minutes to complete a simple online form.

All in all, the risks discussed in this section have three defining characteristics: they are relatively
likely to happen; are strikingly easy to mitigate (we’ll get into that soon); and tend to be so
unglamorous that they seldom make the cut in any “serious” guide to emergency preparedness.

2.2. Problem space #2: Mass calamities https://lcamtuf.coredump.cx/prep/index-old.shtml

If an errant backhoe took out the utilities for your block, you would probably head to the
grocery store to pick up bottled water (and use their restrooms, too). But if a
once-in-a-century storm damaged major roads and left half the city without running water, your
options wouldn’t be as clear-cut.

That’s why we have to look at larger-scale emergencies through somewhat different lens, taking into
account their likely magnitude, duration, and the nature of the forces at play. Some of the
plausible scenarios to think about include:

• Natural disasters.
  Common examples include floods, hurricanes, earthquakes, wildfires, and heatwaves. In some
  regions, such events are fairly rare; in others, they are almost guaranteed every decade or two. But no matter where you
  live, you should expect at least one “storm of the century”, “winter of the century”, or “drought of the century” to happen
  within your the span of your life.

• Industrial accidents.
  Many people live in the proximity of heavy industries – say, refineries, freight railroads, or power plants.
  Depending on the type of industrial facilities nearby, it may make sense to evaluate the potential
  consequences of upwind and upstream explosions or chemical spills. Contrary to pop cultural fears, conventional
  industries, such as chemical plants, have a track record far more grim than Fukushima and Chernobyl.

• Social unrest.
  Riots are a distinct risk in many urban and suburban areas around the world. When angry mobs
  take to the streets, widespread arson and violent crime are not unheard of, sometimes going
  on for days or weeks. While you probably won’t have to fight off an angry mob in a residential
  neighborhood, there might be times when it’s wise to skip some grocery store trips and hunker down.

• Economic crises.
  All highly developed countries go through cyclic recessions and periods of high unemployment;
  the US had about ten big ones in the past 100 years alone. Sometimes, such events
  are accompanied by bank runs and collapses of financial institutions; other times,
  they involve hyperinflation, product rationing, deposit confiscations, or currency controls.

• Pandemic.
  It’s been a while since the highly developed world experienced a devastating outbreak, but it
  may be premature to flat out dismiss the risk. In 1918, an unusual strain of flu managed to kill 75
  million people. Few years later, a mysterious sleeping sickness – probably also of viral origin –
  swept the globe, crippling millions, some for life. We aren’t necessarily better prepared
  for similar events today.

• Terrorism or conventional war.
  History books make us think we would see it coming – but in practice,
  such events are difficult to
  anticipate tend to catch nations off guard. These phenomena are noteworthy not only because of their immediate death toll,
  which can be relatively low – but because of the far-reaching and long-term socioeconomic
  disruption they can cause. The fears of terrorism are often dismissed as irrational, as relatively few people are killed
  by terrorists and very few terror campaigns achieve their ultimate goals; but in terms of the profound
  economic and societal impacts such attacks can have, they are worth factoring into any preparedness plan.

Most of readers will probably not get tangled up in a large-scale disaster of any sort, but it
is wise to hedge our bets. There are countless examples to demonstrate that such events
happen often and can strike close to home – say:

• The EU debt crisis, from 2009 onward. A series of events that led to staggering unemployment rates
  in Greece, deposit confiscations in Cyprus, and uncertain prospects for the entire
  eurozone.

• Hurricane Sandy in 2012. Damaged more than 300,000 homes in the US, left millions
  without power – some for weeks.

• The California wildfires of 2007. The blaze destroyed thousands of homes and forced
  1 million SoCal residents to seek improvised shelter at stadiums and schools.

• Hurricanes Katrina and Rita in 2005. Put 80% of New Orleans under water, stranded
  countless motorists when 3 million people attempted to evacuate.

• A decade of social unrest in France, from 2005 on. A series of widespread
  urban riots led to more than 13,000 cars being torched and hundreds of structures
  damaged or destroyed.

• The European heatwave of 2003. A seemingly benign weather anomaly killed tens of thousands –
  mostly in highly developed and wealthy countries, such as France and Spain.

• The Los Angeles riots of 1992. A startling rampage that resulted in about 2,000 injuries,
  4,500 structures being looted, and some 1,000 buildings set ablaze.

Preparing for such emergencies may seem exceedingly difficult, but much can be
accomplished with very simple tools. For example, if you own a car, always keeping
the tank at least half full, and having a small box of rudimentary supplies in your
trunk, can go a long way. Again, we’ll go over many other low-cost preparedness
strategies soon.

2.3. Problem space #3: The zombie apocalypse https://lcamtuf.coredump.cx/prep/index-old.shtml

Many of the best-known works of science fiction explore the possibility that one day,
perhaps soon, the very fabric of our society may simply unravel – and that those who
survive The Event would be forced to fend for themselves in a ravaged and hostile world.

To connect with the reader, the writers of such post-apocalyptic fiction skillfully play up
contemporary fears, often implying that we may be on the verge of an extinction event or a
fundamental societal shift. The usual literary themes include:

• Uniquely virulent and deadly diseases (28 Days Later, The Stand, World War Z),

• Preposterously violent weather anomalies (The Day After Tomorrow, Snowpiercer),

• Unimpeded emergence of totalitarian techno-dystopias (Blade Runner, Gattaca, The Hunger Games),

• Global thermonuclear war (Alas Babylon, The Day After, Fallout),

• Robots deciding to kill all humans (Battlestar Galactica, Terminator),

• Impertinent extraterrestrials (Edge of Tomorrow, Independence Day),

• Hand-wavy ecosystem collapses (Children of Men, The Road, Interstellar),

• Cosmic collisions (Lucifer’s Hammer),

• Something with magnets (The Core, One Second After).

It’s no wonder that all this vivid imagery keeps many preppers preoccupied with civilization-ending events.
Some of their worries are based on patently absurd or exaggerated science; some are valid, but rather
unlikely to materialize within the span of our lives; and many others boil down to interesting but
somewhat idle speculation, devoid of quantifiable risk or historical precedent.

At least in theory, the recipe for surviving civilizational collapse is simple: we need to get away
from other people and become self-sufficient. It’s fairly clear that deprived of their industrial
backbone, most of our cities and suburbs wouldn’t be able to support even a tiny fraction of their
current population densities – and would become horrid death traps. Living off the grid shields
you from all but the worst doomsday events.

My thinking is simple: if farming is your cup of tea, buy a plot of land in the countryside.
But if you’d rather live the rest of your days without having to skin deer or plow a field,
it probably pays to focus on better quantified and substantiated risks – and not let asteroids or space zombies
keep us up at night.

3. The prepared lifestyle https://lcamtuf.coredump.cx/prep/index-old.shtml

Of course, there is no use in worrying about the hypotheticals if we’re not going to actually tackle the
risks. But it pays to be smart about it, too: when it comes to emergency preparedness, the
right mindset can matter a lot more than a small fortune spent on ninja gear and canned cheese.
So, before going on a shopping spree, let’s talk about several simple, everyday principles
that can shield us from harm.

Much of the content in this section has little to do with hardcore prepping; some of the chapters
touch on seemingly banal topics, such as financial planning, community building, or the prevention
of burglaries and car wrecks. We have all heard most of this advice before – but if we are serious
about risk minimization, one must internalize these rules, understand where they are coming from,
and actually live by them every day.

3.1. Prepper commandment #1: Save some money https://lcamtuf.coredump.cx/prep/index-old.shtml

Some are born into familial wealth or who display supernatural business acumen. Then
there is the rest of us, perhaps having robust and satisfying careers, but ultimately
never getting far enough from the steep cliffs of financial misery.
It may be a matter of our employer going out of business, it may be a shift in
the job market, an illness, or a legal dispute – but in all likelihood, it would not take much to
push us off the ledge. I have friends who lived paycheck-to-paycheck on cozy Silicon Valley
salaries of $150k+ a year, only to lose their cars and homes in the midst of the 2007
financial crisis – having found out the hard way that unemployment benefits in the San Francisco
Bay Area max out at $450 a week, not nearly enough to pay their mortgages or make the rent.

I can’t claim to have advice for people who are already in a tough spot: if your
household earnings are well below median, you may simply have no disposable income to build
a personal safety net. But for most other folks, the ability to prepare for the zero-income
contingency should be within reach. Sure, even a lifetime
of belt-tightening won’t make the average middle-class family fabulously rich. But rainy-day funds
work in a different way: their purpose is to get us through a rough spell, not to pay for a
mansion or a fancy car. Since the amount needed is directly proportional to how much we currently
make, it makes relatively little difference if your household brings in $70k or $140k a year.
Either way, if you set aside 10% of every post-tax paycheck, you should have a 6-month financial
safety net established within 3 years and a change.

This, of course, is easier said than done. We tend to scale up our living expenses in proportion to
earned income, so even among the top 1% of wage earners, people living paycheck-to-paycheck are not a rare sight.
And it’s usually not the big-ticket stuff that gets them: we’re far more likely to overspend on all
the smaller, habitual purchases, because their cumulative cost is less apparent – and potential
savings are much easier to miss. The patterns to look for will depend on your lifestyle and on how
much you make, but here are several suggestions for where to search for that 10%:

• Groceries.

  It pays to shop at less expensive grocery stores and try out lower-shelf brands – especially when
  it comes to commodities such as cooking oil, paper towels, milk, seltzer water, flour, sugar,
  or salt. I’d wager that table salt tastes and works the same, whether we paid $1 at Walmart or $15 for a
  Sherpa-approved Himalayan variety at Whole Foods. Groceries eat up a good chunk of our
  monthly budgets, so even seemingly inconsequential savings tend to add up very fast.
  Even shaving just $15 or $20 off every grocery bill can add up to $1,000-$2,000 extra cash every year.

• Restaurants & taxis.

  Many young, urban-dwelling folks frequently dine at restaurants, go to clubs, or take cabs
  around town. They don’t need to give it all up, but it may make sense to scale back slightly by
  designating several days a week strictly for public transport and home food. Contemporary
  frozen dinners can be surprisingly tasty, and Netflix has some good shows.

• Gadget upgrades.

  If our older phone, laptop, or a TV set are still working fine, it pays to keep them for another year or two.
  The excitement of new gear wears off quickly, usually in a matter of days or weeks, so it can actually
  be liberating to fall behind. There are entire communities
  of computer gamers who only play games at least one year old, and they seem as happy as people living on the cutting edge of tech.

• Subscription services.

  Small monthly fees add up to gargantuan sums over the years, so it’s good to take a critical look at
  cable TV, landlines, gym memberships, and so on. Downgrading to a slower speed for Internet service or
  slightly increasing the deductible on car insurance can result in significant savings, too. Insurance
  works best when it’s purchased for unlikely and catastrophic losses; it’s not a cost-effective way to pay for
  broken side mirrors, cracked windshields, and so on.

• Home improvement.

  Even renters can save big bucks by learning how to reupholster or refinish
  furniture, patch drywall, paint walls and trim, install tile and cabinets, fix or replace faucets,
  unclog drains, and take care of other simple DIY jobs. In addition to saving a lot of money,
  home improvement can be incredibly rewarding, too.

• Vacation.

  Camping trips can be a good alternative to heading off to a popular destination like Vegas, Hawaii,
  or Disneyland. Although it’s nice to have a variety of experiences, by the end of the day,
  trips that involve less stress and less planning can be more enjoyable than high-stakes exotic
  getaways.

• Extra cash.

  If you get a bonus or a raise at work, it’s good to resist the urge to spend it right away.
  Consistently setting aside some or all of the extra income can pay off over time, and helps
  combat the phenomenon of lifestyle creep.

Somewhat counterintuitively, saving money is not just about cutting down expenses;
seeing a higher balance on a checking account can instinctively make us less frugal, too. To
counter this trend, I found it helpful to set up a small, daily transfer to
a savings account, in an amount that blends in with daily purchases – say, $10 or so. This
method takes much less planning and mental discipline than trying to make one big deposit every
month. And hey – once we are comfortable with $10, we can painlessly test the limits by
gently ramping the amount up.

Debt should be approached with suspicion. Many of us are taught that owing money is normal, even
desirable; indeed, for middle-class folks, some forms of indebtedness may be difficult
to avoid. But unnecessarily accrued debt cuts into your bottom line in two insidious ways.
First of all, monthly installment payments limit your flexibility in an emergency – so if your
income shrinks, your savings will be depleted at a merciless and non-negotiable rate. Secondly,
high-interest loans, such as credit cards, amount to giving out a good chunk of your income
without earning anything useful in return. They are akin to voluntarily accepting a pay cut.

As a matter of practicality, I wouldn’t worry too much about your existing mortgages or student
loans: they are difficult to repay early, tend to have very low interest, and confer special
tax benefits. But I’d use your initial savings to pay off credit card balances, and do it quick.
It pays to be careful with new obligations, too. Unless you already have a very generous safety net, a
home loan that eats up more than 15% of your paycheck over the course of 30 years is a
very risky deal; and going over 30% is almost certainly a bad idea, at least as far as financial
continuity planning goes.

As for the optimal size of your emergency fund, there are no hard rules. Around six months’
worth of post-tax earnings should provide a very comfortable cushion for short- and medium-term
disasters of all sorts. Even in a deeper crisis, six months is plenty of time to scale down
expenses, find a new line of work, or regroup in some other way.

Now, chances are, if you follow the advice contained in this section, you will not feel an urge to ramp
up spending the moment you hit the 6-month mark. If so, it’s best to keep going; with the initial rainy-day fund
established and good fiscal habits in place, you can start treating the extra funds with more
flexibility – for example, “borrowing” against them to self-finance larger purchases, or aiming
to retire a bit earlier and a bit more comfortably than the government expects you to. And by the
time your savings are sufficient to get you through a full year of unemployment, I bet that your
outlook on life, work, and personal finance will change in an interesting way. There is a good
if somewhat foul-mouthed essay on this, called
“A Story of a Fuck-Off Fund”.

Oh, one more thing: when trying to reform your fiscal habits, it can be useful to think of money as
a unit of debt owed to you by the society, awarded in exchange for your hard work (or as a consequence
of some other fortuitous event). Despite the
popular saying, when allocated wisely, that money can buy you safety, comfort, influence, or true
friendship and happiness. It would be foolish to squander it on trinkets – just as it would be
foolish to take it with you to the grave. My advice is simple: make every transaction count.

3.2. Prepper commandment #2: Don’t lose what you saved https://lcamtuf.coredump.cx/prep/index-old.shtml

If all goes well, your rainy-day fund will eventually grow big enough for you to face an
important question: how do I keep all that capital safe? Although it may seem like a remote
concern, events such as bank collapses, market crashes, and currency devaluations happen all over the
world with near-clockwork regularity – and there are few things more infuriating and disenfranchising
than finding out that the fruits of many years of your labor have been wiped out by a market panic or
an administrative decree.

The answer to the question of safeguarding your wealth lies in the solution
to another riddle: the mechanism by which the society determines the worth of a piece of money to
begin with. It’s a puzzle central not only to everyday financial planning, but also to any attempts
to decipher and meaningfully evaluate countless mainstream conspiracy theories and doomsday
predictions related to the financial world.

So, let’s start from the beginning! Throughout much of the recorded history, the monetary systems of the
western world employed so-called commodity money, generally settling on coins minted out of
silver or gold. The two metals were favored because of their nearly universal appeal, and because of their
inherently constrained, labor-intensive supply. In this system, early prices likely reflected
the worth of a particular good compared to the valuation of the coin as a non-monetary commodity. Over
time, the exact “melt value” of the coins started to matter less, and the currency functioned as a more
abstract unit of account – but its precious metal content stabilized the economy by ensuring that
the coinage had an inherent and lasting value, even if the issuing state simply vanished from the map.

By the 18th or 19th century, many European countries moved on to a more flexible model where coins were made out
of cheaper metals, and banknotes were printed on paper or cloth. To encourage the use of these new instruments
and to establish their value, the governments or the issuing banks promised to freely exchange such intrinsically worthless tokens
for a predefined amount of gold. In other words, as long as people had faith in their rulers or financial
institutions, the fundamental mechanics of this new representative currency remained roughly the same as before.

In theory, both of these systems looked simple and robust. But there was another, somethwat subversive
force at play:
in the 17th century, many European states witnessed the emergence of fractional-reserve banks.
These private ventures operated according to a simple scheme: they accepted people’s money for
safekeeping, promising to pay a premium on every deposit made. To meet these obligations and to make
a profit, the banks then used the pooled deposits to make high-interest loans to other
folks. The financiers figured out that under normal circumstances and when operating at a sufficient
scale, they needed only a very modest reserve – well under 10% of all deposited money – to be able to
service the usual volume and size of withdrawals requested by their customers. The rest could
be loaned out.

The very curious consequence of fractional-reserve banking was that it pulled new money out of thin air. The funds were
simultaneously accounted for in the statements shown to the depositor, evidently available for withdrawal or
transfer at any
time; and given to third-party borrowers, who could spend them on just about anything. Heck, the borrowers
could deposit the proceeds in another bank, creating even more money along the way! Whatever they did,
the sum of all funds in the monetary system now appeared much higher than the value of all coins and
banknotes issued by the government.

Of course, no new money was being created in any physical sense: all that banks were doing was
engaging in a bit of creative accounting – the sort of which would probably land you in jail if you
attempted it in any other comparably vital field of enterprise. If too many depositors were to
ask for their money back, or if too many loans were to go bad, the banking system would fold.
Fortunes would evaporate in a puff of accounting smoke, and with the disappearance of vast
quantities of quasi-fictitious (“broad”) money, the wealth of the entire nation would shrink.

In the early 20th century, the world kept witnessing just that; a series of bank runs and economic contractions
forced the governments around the globe to act. At that stage, outlawing fractional-reserve
banking was no longer politically or economically tenable; a simpler alternative was to let
go of gold and move to fiat money – a currency implemented as an abstract social construct measuring
indebtedness, with no predefined connection to the physical realm. A new breed of economists saw the role of the government
not in trying to peg the value of money to an inflexible commodity, but in manipulating its supply
to smooth out economic hiccups or to stimulate growth. Depending on who you ask today,
contemporary monetary policies – especially in the era of bank bailouts and debt-fueled GDP boosting –
are either a brilliant way to stabilize free markets and promote wealth, or a reckless charade
that papers over systemic problems and sets us up for serious trouble in the coming years.

That question aside, the obvious peril of fiat money is that in the long haul, its value is determined
strictly by people’s willingness to accept a piece of paper in exchange for their trouble; that
willingness, in turn, is conditioned solely on their belief that the same piece of paper would buy them
something nice a week, a month, or a year from now. It follows that a simple crisis of confidence could make a
currency nearly worthless overnight. A prolonged period of hyperinflation and subsequent austerity in Germany and Austria
was one of the precipitating factors that led to World War II. In
more recent times, dramatic episodes of hyperinflation plagued the fiat currencies of Argentina (1980s),
Italy (1980s), Israel (1984), Mexico (1988), Poland (1990), Yugoslavia (1994), Bulgaria (1996), Bolivia (1990s),
Turkey (2002), Zimbabwe (2009), Venezuela (2016), and quite a few other nations around the globe. The scale of
this phenomenon is surprisingly poorly studied in English-language literature, but at least 56 instances are
documented, most of them within the past 100 years; you can check out some examples here.

For the United States, the switch to fiat money came relatively late, in 1971. To stop the
dollar from plunging like a rock, the Nixon administration employed a clever trick:
they ordered the freeze of wages and prices for the 90 days that immediately followed the move.
People went on about their lives and paid the usual for eggs or milk – and by the time
the freeze ended, they were accustomed to the idea that the “new”, free-floating dollar is worth about
the same as the old, gold-backed one. A robust economy and favorable geopolitics did the rest, and so far,
the American adventure with fiat currency has been rather uneventful – perhaps except for the fact
that the price of gold itself skyrocketed from $35 per troy ounce in 1971 to $850 in 1980 (or, from
$210 to $2,500 in today’s dollars).

Well, one thing did change: now better positioned to freely tamper with the supply of money, the regulators
in accord with the bankers adopted a policy of creating it at a rate that slightly outstripped the organic
growth in economic activity. They did this to induce a small, steady degree of inflation, believing that doing
so would discourage people from hoarding cash and force them to reinvest it for the betterment of the society.
Some critics point out that such a policy functions as a “backdoor” tax on savings that happens to align with
the regulators’ less noble interests; still, either way: in the US and most other developed nations, the
purchasing power of any money kept under a mattress will drop at a rate of somewhere between 2 to 10% a year.

All right. Financial systems are messy. Fiat money and fractional-reserve banking, although
wildly successful, can fail in interesting and horrific ways. Foreign trade, neglected here but absolutely
vital for most European countries, adds even more variables to the mix. So, let’s talk about what can be done
to protect your rainy-day funds against some of the most likely or most talked-about risks.

3.2.1. Fiscal challenge #1: Dealing with “normal” inflation https://lcamtuf.coredump.cx/prep/index-old.shtml

At a rate of 4%, inflation will halve the purchasing power of your savings in about 17 years; at 6%,
the process will take just 11 years and a change. Worse yet, depending on your location and lifestyle choices,
the inflation rate you experience can be much higher than the nation-wide government numbers imply. For example,
the skyrocketing housing prices in the SF Bay Area have halved the purchasing power of some aspiring
homeowners in a matter of five years or so, even though the official inflation figures hovered during that
period somewhere around 2%.

In any case, while it’s seldom a prepper-grade emergency, you probably need to tackle the problem of inflation
sooner than later – or face huge and unnecessary losses down the road.

For our parents, the solution was simple: they had to take their money to a bank. The returns were usually sufficient
to offset the loss, and since the value of their money already depended on the health of the financial system, they
weren’t facing that much added risk. But today, the trick no longer works: people are skittish about the state of
the economy and are trying to play it safe, so banks already have more deposits than they can use – and offer
near-zero interest rates across much of the developed world.

There are many other ways to get returns on your capital, but most are associated with limited liquidity or
significant outlay costs. One well-known exception are publicly traded companies. Businesses usually go public because
they want to expand their operations – say, build a new factory or hire more workers. Instead of getting an
expensive loan, they put themselves up for sale, allowing people to purchase and trade fractional ownership in the company.
The investors’ willingness to pay for this privilege depends on two factors: the intrinsic value of the enterprise
(its assets, debts, revenue streams) that they get a claim on if the company goes private, is acquired, or liquidates;
and the “hype premium” – the faith in the company’s long-term prospects and the health of the entire industry. For some
companies, the intrinsic value is modest, and the premium is huge; their shares are usually subject to violent price
swings on even seemingly minor macroeconomic news. For other, less exciting businesses, the situation may be the opposite.

The conundrum of owning stock is that it serves as a hedge against inflation only in an otherwise viable economy.
At the first sight of serious economic trouble, the premiums paid on corporate stocks take a nosedive and not recover for
months or years; in a genuine downturn, the intrinsic value of many companies will also shrink. Since a downturn
is probably the time when you will need your rainy-day money the most, it’s important to play it safe. Putting somewhere
around 30-40% of your emergency stash into the stock market may be a good call. Going all in is a very risky bet,
since in an economic crisis, it’s not rare to see stock indices plunge 50%.

The fundamental rule is to not be greedy: within the scope of this guide, your goal should
be to preserve capital, not to take wild risks. It’s best to pick about 10-20 boring
companies that seem to be valued fairly,
that are free of crippling debt, and that have robust prospects for the coming years. I’d stay clear of financial enterprises,
of highly speculative sectors such as biotech, cannabis, or solar power, and of heavily regulated industries that lack the flexibility to
deal with sudden economic shifts (say, airlines). Relatively safe picks can be found in no-frills
domains: basic chemicals, staple electronic components, profitable freight railways, mechanical assembly
manufacturing, home and office supplies, and so on.

It is worth noting that many personal finance experts advise against hand-picking your investments. Instead,
they advocate a process known as “indexing”: buying into an investment vehicle comprising hundreds of stocks,
structured to represent the stock market as a whole. The proponents of indexing have a point: most people who try to pick
individual winners in the stock market usually fare no better than an index fund. But in the context of prepping, I think
this is advice is flawed. To remain calm in tumultuous times, it is important to maintain a firm grasp of the merits of your
investments. One can convincingly reason about the financial condition, the valuation, or the long-term prospects of a paper mill;
the same can’t be said of an S&P 500 index fund – which, among other things, contains the shares of
about a hundred global financial conglomerates.

3.2.2. Fiscal challenge #2: Having no access to your bank account https://lcamtuf.coredump.cx/prep/index-old.shtml

Sooner or later, you may find yourself unable to access your bank deposits for a couple of days or
weeks. It could be a matter of IT trouble at your bank, of a lost wallet, or of being a victim of identity
theft. Heck, take Greece or Cyprus: when the confidence in the nation’s financial institutions is shattered, it’s
easy to get caught up in government-imposed bank closures and withdrawal controls. (Folks in the United
States may also recall the forced closure of Washington Mutual in 2008, or several state-level “bank holidays”
imposed to combat bank runs during the savings & loan crisis back in the 80s.)

For short-term survival, simple solutions work best: just keep about 2-4 weeks’ worth of cash somewhere at hand;
have enough money on you to get you back home when traveling, too. Of course, be mindful of the risk of burglary, so if
you’re keeping the funds at home, pick an unobvious location for the stash; more about that soon.

As for the remainder of your money, I suggest splitting it across two largely unrelated financial institutions with
different risk profiles – say,
a big national bank and a local credit union. As long as the deposits are insured by the government (as they
normally are in the US and in Europe, up to a per-account limit), this
approach greatly increases the availability of your money, and probably doesn’t expose you to any substantially new dangers.
Keeping all your savings outside the banking system is an option, too, but it’s not necessarily a smart choice.
With fiat currencies, this move does not truly insulate you from that many longer-term risks, but adds the very real
possibility of losing all your funds to fire or theft.

Perhaps of note: over the past 5 years, many European governments have moved to
severely restrict the use of cash by imposing per-transaction or daily limits as low as $1,000.
The stated reasons have to do with money laundering and tax evasion, but such measures broadly
make it harder to store or use physical currency, even if you’re not doing anything wrong.
In the US, some cash transactions over $10,000 are subject to reporting, too.

3.2.3. Fiscal challenge #3: Dodging hyperinflation and “bail-ins” https://lcamtuf.coredump.cx/prep/index-old.shtml

Ask a financial advisor about the possibility, and they will probably recommend keeping some of your funds
overseas. But the odds aren’t great of correctly picking a currency with more staying power
than the one in which you get paid. Historically, the Swiss franc had a reputation for being an exceptionally
safe choice, in part because of being the last major currency still quasi-pegged to gold; but Switzerland
abolished this requirement in a referendum around the year 2000.

Another complication is that even if you make the right call, many governments impose onerous reporting
requirements on foreign assets – and especially in times of economic hardship, they treat them with
suspicion and contempt. Host countries are also more cavalier about confiscating foreign deposits,
as evidenced by the Cypriot “bail-ins” in 2013. Lastly, the public associates overseas accounts with
tax evasion and money laundering, so it may be difficult to garner any sympathy for your case when
things go wrong.

One school of thought popular in the prepper community is to convert some of your savings into commodity
metals: copper, tin, silver, platinum, palladium, and the likes. All of them are easy to store, last
indefinitely, and will certainly hold value far better than a fiat currency in free fall. On the flip side,
you may still need to accept substantial loss: an economic collapse will disrupt industrial demand,
causing the prices of many such commodities to slump.

This brings us to gold: this metal occupies an interesting niche, because its value is driven chiefly
not by industrial applications, but by direct consumer demand and by its status as a mainstream financial
instrument. In fact, investors and governments alike frequently flock to it in times of economic uncertainty and
stagnation,
as they did in the wake of the financial crisis of 2007. Of course, this goes both ways: should the economy
pick up steam, the demand may decrease and the currently elevated prices of gold may fall closer to their
historical, inflation-adjusted average of perhaps $800-$1,000 per troy oz. Still, the metal is an interesting
hedge against economic disasters, especially given that it is very easily bought and sold. If you are worried
about hyperinflation, you may want to convert some of your savings into this shiny commodity, although I
wouldn’t go over 20-30% or so, as the poorly-characterized volatility of metal prices can sting
in the short haul.

Because of its very high value-to-volume ratio, physical gold is stored and moved around very easily, but keeping substantial
amounts at home can be ill-advised; theft is a very real risk, and most insurance policies will not adequately
cover the loss. Safe deposit boxes at a local bank, available for around $20 a year, are usually a better
alternative – although they come with some trade-offs; for example, the access to deposit boxes was
restricted by the government during the Greek debt crisis in 2015. Non-bank storage services do not have
that problem, but cost quite a bit more.

3.2.4. Fiscal challenge #4: Oh no! Zombie apocalypse! https://lcamtuf.coredump.cx/prep/index-old.shtml

The global financial system simply disappears. Mutant hordes roam the earth!

The preservation of wealth after a civilization-ending event is a popular topic of idle banter in the
prepper community. Some folks believe that commodities such as silver and gold would return as the basis of
a primitive post-apocalyptic economy – and if we’re wildly speculating, in the longer haul, that seems like
a somewhat plausible guess. But in the immediate aftermath, it seems more likely that economic activity would be minimal and
limited to barter or communal ledgers. Nobody would want to exchange a candy bar for a gold coin if they
can’t be sure about being able to find any other food.

This may sound like a good argument for putting all your money into freeze-dried meals, medicine, shovels,
and other survival supplies. But of course, that decision would become a huge liability should the
apocalypse not come, or simply not come soon enough: you probably can’t pay a roofer or a dentist with a
pallet of ammo, cigarettes, and canned ham.

Here’s my advice: keep the bulk of your savings in cash, stocks, real estate, or other assets you can easily liquidate
or put to use today; even if you genuinely worry about the apocalypse, plan to spend no more than 2-4% of
your money on essential prepper supplies. When the zombies come, your financial instruments will almost certainly
become worthless; but you better believe that the value of your survival gear will increase 100-fold.
Zombies or not, your net worth will be safe. Your delicious, tasty brains – well, that’s something to
worry about!

3.3. Prepper commandment #3: Learn new skills https://lcamtuf.coredump.cx/prep/index-old.shtml

In the 90s, it seemed that one couldn’t go wrong getting into professional journalism,
opening a video rental store or an arcade, or selling calculators, encyclopedias, disposable
cameras, answering machines, and audio CDs. We would be very naive to hope that the next twenty
years will not bring similarly dramatic disruption to many of the seemingly cozy professions of today.

So, here’s another suggestion for building a comprehensive preparedness plan: it’s good to develop
and maintain useful and marketable secondary skills. A simple and enjoyable way of doing so is to pick a
hobby we can get passionate about – and then work hard, be very honest about your own mistakes and
shortcomings, and try to get better at it every week. One probably shouldn’t
seek immediate profits, since progressing from a hobby to a paid occupation inevitably takes away some
of the fun; but it helps to gravitate toward pursuits that could conceivably morph into viable career
choices within a decade or so. For families, it can be good to encourage spouses or children to pursue
thoughtful hobbies of their own, too.

The value of such a step extends beyond the mere task of shielding you from glacial shifts in the job market: if
a major disaster suddenly cripples the local economy, there may be no more jobs for HR specialists
or account executives, but carpentry or metalworking skills could be in high demand for the coming
year or two. You can never predict it exactly, but the more you can do, the better you can cope with
whatever adventures come your way.

When it comes to recommendations, there is no short list of hobbies that are objectively better than the rest; the selection is vast,
and the right choice will inevitably depend on your own interests, natural talents, the space you have
available, and on countless other constraints. That said, here are some fairly popular options that may
be worth thinking about:

• Woodworking and carpentry,

• Metalworking, knife making, gunsmithing,

• Glassblowing, pottery,

• Sewing, embroidery, leather crafting, toy making,

• Amateur electronics or robotics,

• Computer programming,

• Graphical design,

• Creative writing or online journalism,

• Farming or hunting (in rural regions),

• Community education and local charity work.

Not all of these hobbies can be turned into well-paying gigs unless you truly excel at them – but they
are guaranteed to be challenging, meaningful, and fun. The Internet gives you ample opportunities to
learn from others, compare notes, and get feedback on your work – all without prematurely subjecting
yourself to the pressures of the commercial marketplace.

Of course, marketable hobbies aside, some of the more determined preppers pursue interests such as
martial arts, pro marksmanship, bushcraft, paramilitary combat tactics, and other extreme survival strategies.
Such talents can be quite useful in a couple of plausible if unlikely scenarios – but their major
disadvantage is that during a simple economic downturn, they won’t put bread on the table or pay your bills.
It’s not unwise to give them some consideration, but be sure to balance it with more pragmatic skills.

3.4. Prepper commandment #4: Don’t hurt yourself https://lcamtuf.coredump.cx/prep/index-old.shtml

Unintentional injury may seem like a topic unbecoming a true prepper, but even the most hardcore survivalist may
find it hard to live out a
post-apocalyptic Mad Max fantasy with a bum leg or a broken neck; and more prosaically, serious prior injury
may limit your ability to provide for yourself and your family, confront a burglar, or get out of a burning
home. It may seem like a far-fetched worry, but – as noted earlier –
the lifetime probability of suffering some form of harm is much greater than we intuitively suspect.

Now, there are some dangers to life and limb that we simply can’t predict or prevent: the occasional falling piano,
the murderous roommate, the untimely stroke. Then there are the risks we take on purpose, accepting
the inherent and unavoidable trade-offs of our hobbies or jobs: the possibility of being snatched by a giant squid
while snorkeling off the coast of California, or the near-certainty of lung fibrosis from toiling in a
sugar mine. These are the things we can’t or don’t want to give up – and that’s perfectly fine.

But there are also the “hold my beer” moments: the unnecessary displays of bravado, overconfidence, or
thoughtlessness. We recognize them from cringeworthy Youtube clips of people getting hurt –
but we are guilty of the same: we get honked at for carelessly changing lanes, we end up climbing more than
a fair share of rickety ladders and office chairs, and every now and then, we all get a bit cavalier with
lawnmowers, escalators, ATVs, or other power tools.

We keep getting away with all that goofiness, and that only serves to make us more certain that our own
transgressions carry no serious risks. But government statistics tell a strikingly different tale: in the US
alone, unintentional injuries result in 40 million ER visits and 100,000 deaths every year. Heck, accidental
injury is the leading cause of death for people between the ages of 1 and 45 – far ahead of cancer, heart disease,
gun violence, and other pop culture bogeymen. And the injuries themselves are very prosaic, too: all you see
are falls from modest heights, cuts, burns, vehicular collisions, poisonings, and so forth. The “idiots” we
sometimes watch on Youtube are us. They just happen to have been caught on camera on the day their luck ran out, perhaps aided by
downing a couple of beers.

In the end, ladders, cars, and space heaters are a much greater threat to our well-being than a gun-toting
robber or an army of zombie marauders could ever be. So, gleaned from accident statistics, here are some of
the familiar-sounding but crucial survival tips. It may sound unlikely, but if something appears on this
list, it’s responsible for quite a few gruesome deaths or injuries every year; it pays to take it to heart.

3.4.1. Safety tip #1: Don’t be stupid when working at heights https://lcamtuf.coredump.cx/prep/index-old.shtml

Working at heights can be a prime example of an unnecessary risk: sure,
the lightbulb needs changing and that office chair is really close, but it would take us just 15 more
seconds more to bring a more sturdy stool from another room. Similarly,
having someone hold a wobbly ladder for us or securing it with some rope can be a minor hurdle – but it’s gonna be
much less of a hurdle than dealing with a compound fracture or a dent in one’s skull.

Whenever working at heights, it’s good to remember that we
probably experienced most of our falls as children, and that can profoundly skew one’s perception of danger: falling five feet
and landing on your side is different when you weigh 50 lbs, and different when you are 180 lbs.

3.4.2. Safety tip #2: Drive defensively and stay calm on the road https://lcamtuf.coredump.cx/prep/index-old.shtml

Car accidents are a major source of injuries, and the methods to mitigate the risk are familiar to most:
don’t go too fast, keep a three-second distance to the vehicle in front of you, and always scan
for cross traffic when approaching intersections or making turns (other drivers may be less attentive than
you). It’s also good to be very careful when changing lanes, do it slowly, and be sure to adjust one’s
mirrors to eliminate blind spots (you don’t really need to see the sides of your car). Next, it’s worthwhile
to slow down for cars stopped in other lanes – they may be letting a pedestrian through. Finally,
there are clear benefits to wearing seat belts, keeping children in fitting car seats,
getting some rest on longer trips, and not talking on the phone – it doesn’t matter that it’s hands-free.
I’d avoid frequent rides with people who drive badly, too.

Interestingly, driving and safeguarding your finances have something in common: when you end up hurting
another person in an at-fault accident, they may go after your savings or real estate to recoup medical
expenses, lost wages, and other costs. So, in addition to driving defensively, it makes sense to take a look at your insurance
policy. The minimum liability coverage mandated by the state can be as low as $15,000; relatively few victims
will settle with the insurer for that amount if they think that taking you to court could net them ten times as much.
Bumping your limit to $250,000 is usually pretty cheap. In fact, if you have collision coverage,
you can more than make up for it by increasing your deductible to $1,000.

As for biking on public roads: it pays to wear a helmet and bright-colored clothing, to stay well clear of the doors of parked
vehicles, move in a straight line instead of weaning in and out of the traffic,
and watch for cars trying to make right turns. It’s good to scan for cross traffic at intersections
and signal all turns. Conversely, it’s unwise to run red lights –
the risk is not worth the seconds shaved off your commute. Last but not least, it’s a bad idea to ride
without holding the handlebars; it’s a cool skill, but when you do that, a single rock or an
unnoticed pothole can throw you right under the wheels of a passing bus or down the ravine.

3.4.3. Safety tip #3: Show respect to dangerous machines and chemicals https://lcamtuf.coredump.cx/prep/index-old.shtml

It’s best to read up on the safety rules pertaining to your weekend hobbies and to your daytime job; I’d also
ask others about their horror stories and vigorously take notes. One should always be careful around power tools
such as chainsaws, table saws, angle grinders, lathes, and nail guns – they have quite a penchant for taking fingers off and eyes out. (Table
saws in particular are responsible for about 30,000 serious injuries annually, or about 40% of all workshop
accidents.)

In general, it’s best not to horse around any heavy machinery; if it’s weighs more than you, it can kill you
in the blink of an eye. This is also important for children: we should teach them
not to play behind or under parked cars. And if you have a toddler, it’s good to use straps to secure rickety dressers and
other tall, heavy furniture.

At home, my other advice would be to stay alert around deep fryers and pots of boiling water. It’s also
good to wear eye protection when working with
drain cleaners, bleach, and other caustic substances. Lastly, it’s useful to learn
about the overdose risks of paracetamol (ibuprofen is a much safer pick) and take a critical look at your prescription
drugs, especially when it comes to opioids. If you’re ever doing DIY electrical work, I’d learn how to do it properly,
and get a non-contact voltage probe to double-check for live wires before touching anything.

3.4.4. Safety tip #4: Don’t die in a fire https://lcamtuf.coredump.cx/prep/index-old.shtml

One of the well-known defenses is to install smoke detectors and keep them operational; if they are going off too often,
it’s possible to move them farther away from the kitchen, or switch to photoelectric sensors, which are much less
sensitive to minor cooking mishaps. If running new wiring is a challenge firmly outside your DIY comfort zone,
there are many long-lasting battery-operated units to choose from.

It’s also good to get at least two good-sized ABC fire extinguishers (5-10 lbs or so) and keep one in
your bedroom. Similarly, it helps to learn how to deal with oil fires, to avoid stockpiling excess flammable materials,
and to be very careful when pouring flammable liquids near open flames (this includes alcoholic drinks).
Other tips include watering your Christmas tree and using LED tree lights; or unplugging devices with lithium-polymer batteries
when leaving home. Finally, it’s important not to put grills next to siding-clad walls and not to overload extension cords;
and when cooking, it pays to stay in the kitchen or set a timer to remind yourself that the oven is on.

3.4.5. Safety tip #5: Just in case, keep your senses razor-sharp https://lcamtuf.coredump.cx/prep/index-old.shtml

If you’re regularly drinking or doing psychoactive drugs, try to kick the habit – or at least scale it back.
I’m not going to give you a talk about the evils of cannabis, but by the end of the day,
impaired judgment is impaired judgment. It inherently increases the odds of waltzing into trouble or
getting hurt.

3.5. Prepper commandment #5: Don’t become a victim https://lcamtuf.coredump.cx/prep/index-old.shtml

In addition to the dangers of poor financial planning and the ever-present specter of
unintentional injury, another threat we should reckon with is becoming a victim of a crime.
Although the risk is not as pervasive as the challenges discussed earlier in this chapter,
it still earns a distinction as one of the things that many readers may have to face at
some point in their lives.

Ask a hardcore prepper for advice on this matter, and they will probably tell you to start practicing hand-to-hand
combat, get a knife, or carry a gun. But in reality, we need a more nuanced and proportional approach to threats,
and one that emphasizes avoidance and de-escalation, rather than the ability to resolve each and every
conflict with a single well-placed shot. Sure, a self-defense weapon can save your butt in some life-or-death
situations, but these are comparatively rare; such a tool won’t deter a pickpocketer, won’t stop a
burglar from ransacking your place while you are at work, and won’t prevent a hacker from emptying your bank
account while you’re busy watching the reruns of Gilmore Girls.

In other words, while this guide certainly doesn’t have an anti-self-defense or an anti-firearm
slant, we’ll try to take a broader view before delving into the comparative merits of
karate chops, blade weapons, firearms, stun guns, and pepper spray.

3.5.1. Defense tip #1: Practice situational awareness when on foot https://lcamtuf.coredump.cx/prep/index-old.shtml

When walking around town, it’s useful to keep scanning your surroundings and be mindful of people around you; it can be
dangerous to get lost in thought in transitional spaces, such as pedestrian underpasses, back alleys, or empty parking lots. If your spidey
senses are tingling, I’d just bail: make a sharp turn and sprint away. I wouldn’t worry that some random dude
who is closing up on me at night might be perplexed or offended by your move.
It’s also important not to freeze up if somebody hollers or authoritatively barks an order at you – complying is a very
powerful instinct, and some assailants know to exploit it. If a stranger in a parking lot has no discernible business with you, there’s
limited value in letting them get close.

Of course, some street-savvy readers may consider it to be in poor form to sprint away from a threat, and may be
inclined to confront the danger and see where that takes them. It’s an OK choice if you are well-armed or
physically fit, but is certainly not a way to minimize the probability of harm.

3.5.2. Defense tip #2: Make yourself pickpocket-proof https://lcamtuf.coredump.cx/prep/index-old.shtml

In shopping malls, on mass transit, and in other crowded settings, I wouldn’t carry my most precious
valuables in front or back pockets; a purse is also a clear no-no. Inner pockets of jackets, and chest- or
knee-level pockets of pants and shirts, are much harder to muck with. Discreet, slim waist
packs or under-the-garments neck wallets work even better. If you’re fashion-conscious, it may help to
emphasize to your friends that you are wearing such accessories only ironically. It might even start a trend!

3.5.3. Defense tip #3: Protect your valuables at home https://lcamtuf.coredump.cx/prep/index-old.shtml

Most break-ins are purely opportunistic: thieves are in and out within five minutes, quickly rummaging
through all the places where people usually keep valuable stuff. You can bank on them going through
every nook and cranny of your bedroom, looking under the mattress, peeking into every drawer –
and grabbing everything that looks shiny and is easy to lift. Their usual targets include phones,
cameras, tablets, laptops, jewelry, firearms, loose cash, checkbooks, credit cards, and prescription
meds. Vital documents that may be useful for identity theft or benefits fraud, such as drivers
licenses, passports, and SSN cards, are also a fair game.

Break-ins are difficult to prevent, especially in suburban single-family homes with secluded backyards and
street-level windows and doors; tall fences and window bars can work, but they are expensive and
tend to draw the ire of your neighbors. The most cost-effective solution may be to keep your windows
and doors closed when away, but beyond that, just optimize for hassle-free
outcomes. You can leave some less important goodies in plain sight – say, some cheap jewelry, a modest
amount of cash, and a beat-up phone – and put all the real valuables in a much less obvious or less
accessible spot.
A heavy safe will usually do; diversion safes fashioned into books, cans or clocks
are pretty cool, too – if you trust yourself not to accidentally throw them away.

We’ll talk about home security equipment later on – but in general, devices such as alarm systems, cameras,
or sophisticated locks play a lesser role in keeping your belongings safe; a well-trained dog can work wonders,
but especially in an urban or a suburban setting, such a pet is a substantial commitment (and can turn out to be
a lazy bum).

If there’s another powerful and low-cost
burglary prevention tool at your disposal, it’s being careful not to attract targeted theft. Be mindful
of who you invite into your home, who handles your keys, and how much you signal about your financial status to
your more distant family, random acquaintances, or strangers parked across the street. If you have children, it’s
probably good to teach them not to brag about what they have at home.

Advertising your wealth aside,
another sure way to invite burglars is to make it seem that your house is unoccupied: packages piling up in front,
an overflowing mailbox, an empty driveway, all lights turned off at night. Asking a neighbor to park a car
in your driveway, putting some lights on a timer, and having someone pick up your mail,
are just several examples of low-cost solutions that are worth trying out whenever going on a longer trip.

3.5.4. Defense tip #4: Plan for dangerous encounters https://lcamtuf.coredump.cx/prep/index-old.shtml

Sometimes, you can’t avoid a confrontation. It’s good to rehearse potential reactions if somebody asks you to get into a car,
demands cash, or barges into your occupied home. It would be a complete shock for you, but they
have probably done it before – so you gotta practice if you want to have the upper hand. Even if they have a
weapon trained on you, it’s a game of confidence and wits, not just physical force.

For muggings, keeping several $10 or $20 bills in your front pocket (and having real valuables somewhere else)
can be enough to send them on their way; in busy locations, you should also be able to just
ignore the mugger and briskly walk away. For more serious incidents, it may be useful to respond with something
that is non-threatening but catches the assailant off guard. Simply feigning a panic attack or initiating
a startling conversation (“hey, are you a friend of CJ’s? Pretty sure we’ve met last year!”)
can throw them off balance – buying you a split second to fight back or get away. Of course, you also need a plan for
that next step; that’s where your running skills, your bare-hands self-defense talents, or
your weapons proficiency can come into play. But again, you need to actively practice and develop approaches
that have a chance of working in real life; there’s no verbal diversion strategy in the world that would
give you enough time to fumble through your purse to find an old, gummed up can of pepper spray.

For home intrusions, you should try to act out various scenarios: say, confronting the bad guy or trying
to escape. Take into account that break-ins can happen at different times of day or night. Remember that
intruders may have varied intents, too; some folks may be homicidal or high, but most will just
want your laptop and will be very worried about getting hurt. Many robbers work in pairs, too.

Whether you like it or not, you may eventually have to defend yourself, so be
sure to understand the law. Nobody should take such advice from random people on the Internet, but as far
as I can tell, in much of the US and in many other western countries, you have no duty to run away from an attacker
and can use deadly force if you have a reasonable and immediate reason to fear for your life or the
lives of others. But there are exceptions; for example, despite recent reforms, a duty to retreat outside
one’s home exists in several northeastern states and in some corners of the Midwest. There are also
differences in how seemingly similar self-defense statutes get interpreted by the police, by prosecutors,
and by courts in different parts of the world.

3.5.5. Defense tip #5: Don’t be an easy target online https://lcamtuf.coredump.cx/prep/index-old.shtml

Your cyber-life matters – or at the very least, your bank account password and your credit
card numbers do. To avoid falling prey to hackers,
keep your software up-to-date, choose decent and unique passwords for all
important websites, don’t install sketchy freebies, and don’t fall for legit-looking but
unexpected messages, prompts, or phone calls. When in doubt, just leave the site you were on or
hang up the phone, do some web searches to understand what’s going on, and maybe try again some time later.
Attackers often try to create a false sense of urgency to get you to make rushed decisions; in reality, whatever
it is that you’re asked to do, it can wait.

Be sure to make offline backups of any documents you can’t afford to lose, and don’t keep anything
too embarassing on your computer; ransomware is a very real threat, and it’s best not to put yourself
in a position where you have no choice but to pay the hackers.

Beware of financial scams. If you get an IM from a friend on an
unannounced overseas trip urgently asking for a loan, call them or check in with their family
first. There’s probably no inheritance waiting for you in Nigeria, your chatroom bride-to-be in

3.5.6. Defense tip #6: Don’t make enemies https://lcamtuf.coredump.cx/prep/index-old.shtml

If we’re doing something that’s morally reprehensible or socially unwelcome, we’re
greatly increasing the odds of getting hurt. It doesn’t matter if we think it’s perfectly legal:
if we build a reputation as malicious jerks, a bored prosecutor will probably dream up a
felony charge to hit us with. Or perhaps they won’t, but one of the people you wronged will lose it and
take justice into their own hands. In other words, if one wants to escape harm, they shouldn’t mess with
others out of malice, jealousy, boredom, or for petty personal gain.

3.6. Prepper commandment #6: Get in shape https://lcamtuf.coredump.cx/prep/index-old.shtml

In the United States, about one in three adults is obese – that is, are overweight to the
point where the condition likely interferes with their health or their daily lives. And while many
folks in the prepper community tend to grossly overstate the importance of tip-top physical fitness,
there is no denying that obesity is a very real foe. For example, among low-BMI males around the age of 40,
the incidence of diabetes hovers around 1-4%, but the same number skyrockets to 50-80% for obese guys.
Many other, serious metabolic and cardiovascular diseases follow the same curve – and can make it
very difficult for the affected families to cope even with fairly prosaic and short-lived emergencies.

In all likelihood, if you are obese or slowly getting there, you know quite well that losing some weight is not really the hard part:
if you were to stop eating for a week, you would likely shed 5-10 pounds. But it would
be a miserable experience, and one almost guaranteed to be followed by an even faster rebound. So, the real
challenge of weight management is coming up with a long-term strategy that does not amount to torture –
and does not leave us constantly craving for familiar foods.

Alas, most of the popular diets make this task awfully hard: they force their followers to abandon a
lifetime of dietary habits, taste preferences, and eating schedules – and stuff themselves full of kale, turnips,
quinoa, acai berry, or whatever else happens to be this week’s “fat-fighting superfood”. To add insult to injury,
most of the nutrition fads are not actually backed by real, reproducible science; suffice to say that in the 70s,
table sugar
was widely touted as a dieting aid. Even today, weight loss advice tends to revolve around robustly debunked
concepts – say, the existence negative calorie foods, the alleged superiority of low-carb but high-fat diets, the evils of
HFCS and aspartame, or the significance of eating meals on a particular schedule thoroughout the day.

Just as importantly, our innate nutritional instincts can be badly misguided, too: for example,
contrary to common wisdom, bananas are not really healthier than potatoes, and the bulk nutritional qualities
of a glass of apple juice are pretty close to those of a can of Sprite. Heck, good ol’ butter has fewer calories than
olive or coconut oil, so a “healthy” bruschetta is not far off from a less-reputable southern delicacy:
deep-fried butter on a stick. It gets better: a supposedly nutritious
burrito from Chipotle easily packs four times as many calories as a greasy burger from McDonald’s, while a
loaded coffee at Starbucks is about the same as downing two hot dogs with a heaping
side of mashed potatoes to boot. The end result is a
truly abysmal track record for most weight loss regimes; the long-term success rate for people who try to slim down
is estimated to be somewhere between 5 and 20%.

My advice is that if you want to lose weight, it’s best to stay away from celebrity-endorsed diets,
dubious nutrition claims, and rigid, unworkable plans that seek to control your every urge. While every
situation is different, here are several ways to eat less while still staying happy:

• Start your breakfast with
  high-quality protein powder and
  insoluble dietary fibers (about 20-30 grams each; you can mix them together in a cup of cold water). There is reasonable
  that fiber and protein can increase satiety and reduce cravings thoroughout the day. It’s not “natural”,
  but it beats making implausible resolutions to organize your life around low-calorie, fiber-rich meals – especially
  if you don’t like veggies or don’t usually cook your food.

• Beyond this, stick to your favorite foods and don’t feel pressured to skip regular meals – but cut all
  portions in half, even if it means throwing a half-eaten burger out. Don’t go back for seconds, too.
  It will feel wrong the first couple of times, but it’s surprisingly easy to do. That’s because portion control
  is almost completely psychological; your blood hormone and nutrient levels go up only some time after you cleaned your
  plate. Eating more slowly can make this step a lot easier, too.

• For habitual snacking in front of a computer or a TV, see if you can substantially reduce calories while still
  sticking to satiating and tasty treats. This can be easier than it sounds: say, helping yourself to a nice
  serving of salted popcorn (110 kcal), preparing a cup of
  buttery mashed potatoes (110 kcal), grabbing some
  quick oatmeal (130 kcal),
  or sipping some hot instant chicken soup
  (50-80 kcal), is an excellent alternative to Cheetos, M&Ms, or even supposedly healthy peanuts
  (easily 400-600 kcal). If you enjoy pickles or raw sauerkraut, they are extremely low-calorie, so have as
  much as you want; in the same vein, carrots are a pretty guilt-free choice. Chewing gum can keep you occupied
  between meals, and if you are downing multiple cans of sugary drinks a day, artificially-sweetened sodas offer a
  good alternative (despite some ongoing controversy).

• When buying food, don’t fall for “diet”, “reduced fat”, “low sugar”, or “low carbs” ice cream, yogurts, cakes, pizza,
  pasta, and so on – the differences are so minor that you might as well have the real thing and stop
  fooling yourself. Watch out for deceptive portion sizes, too. For example, Cheetos are labeled as 150 kcal
  per “serving”, but there are almost 10 servings in a regular bag! Frozen fries are another great example:
  they look pretty low-cal until you realize that a serving is just 10-15 pieces or so – certainly not enough
  to make you feel full.

• While dieting, try to drink a bit more and start taking
  OTC multivitamin supplements; they don’t offer
  clear-cut benefits under normal circumstances, but they can compensate for mineral and vitamin
  deficiencies if you never had a particularly thoughtful diet, and are about to start eating less than you
  were accustomed to.

• Probably don’t hit the gym. Hold off with intense workouts at least until you are close to your target weight.
  Daily exercise schedules are hard to keep for more than a couple weeks, especially if you lead a busy
  life; on top of that, a drastic increase in physical activity can trigger cravings or upend your
  nutritional needs. If you are itching to burn some extra fat, incorporate less punishing activities
  into your daily routine – say, walking or leisurely biking to work.

• Be in this for the long haul. Effortlessly losing 1-2 lbs per week while slowly developing better
  habits is far more meaningful than starving yourself for a month to get immediate but short-lived
  results. Get an accurate bathroom scale, take daily measurements first thing in the morning,
  calculate key milestones, and put it all in a spreadsheet to keep yourself honest and motivated.
  It will probably take 6-9 months to get the outcome you want; daily or weekly weight
  fluctuations are almost completely meaningless, but you should be seeing
  a consistent and predictable biweekly drop.

I can’t promise that this approach will work for everyone, but after trying countless other methods,
this is roughly the formula that worked for me.

Of course, if you are very obese or have any serious health conditions, such as diabetes or CVD, talk
to a doctor first. In such situations, aggressive dieting can carry additional risks and calls for
some monitoring along the way; a routine blood test or an ECG shouldn’t cost much. And it goes without
saying that if your diet makes you feel listless or sick, it’s definitely time to stop right away!

Now, when it comes to fitness per se,
I firmly believe that there is no need to go overboard; good health is far more important
than Rambo skills. While getting buff may be a fun pastime for some young folks, there are
very few emergencies that would force you to run 30 miles or climb a 20 foot wall. Being able to
walk or bike for several hours is likely good enough to deal with all practical scenarios we talked
about thus far.

3.7. Prepper commandment #7: Make friends with neighbors https://lcamtuf.coredump.cx/prep/index-old.shtml

The thing about disasters is that they seldom unfold precisely as planned. Perhaps you will lose a job
and get robbed the same week. Perhaps in the middle of a prolonged outage, you will find out that some of
your emergency supplies have been misplaced, damaged, or spoiled. Maybe your plan to walk a mile to get
drinking water from a river will get foiled by a broken limb. And maybe a well thought-out home defense
strategy will prove worthless when standing eye to eye with an angry mob of rioters armed with rocks.

In trying times, people always come together and find strength in local communities. Even if you
don’t expect it, you will almost certainly be able to count on the kindness of strangers. But your
odds can be greatly improved by getting to know your neighbors ahead of time, by cultivating
trust and mutual respect, and by getting a sense of each others’ toolkits and skills. In a grim
situation, being on good terms with a doctor or a veterinarian can quite literally save your life.
And heck, some rural communities in the US even maintain communal stashes of emergency supplies!

Of course, it goes both ways: one will almost certainly find it harder to get help if their neighbors still resent
them for puking on their doormat and constantly partying at night; so once again, not being a
jerk to other people is not just good manners, but a very legitimate survival skill. Even if it’s not
really our nature, it pays to say “hi”, engage in small talk, and offer to help with minor hurdles every now and
then. It’s good to bring your neighbors a pie or some donuts, add them on Facebook, and try to find common interests.
Socialize with coworkers who live nearby, too. Even if the zombie apocalypse never comes, it
probably won’t be a waste of your time.

Now, many “true” preppers advise newcomers to keep mum about your plans, so that in an emergency, you don’t have
to fend off armies of freeloaders begging for a slice of your meager supplies – or worse yet, trying to take them by
force. I think that this attitude is short-sighted; sure, it makes sense not to broadcast your plans
to the entire world, and there is no conceivable benefit to posting Facebook selfies with your stash
of freeze-dried food or with a pile of cash. But the clear value of convincing some of your friends to
start prepping greatly outweighs the distant possibility
that one of them will attempt to raid your home the moment the power goes out.

3.8. Prepper commandment #8: Write down a response plan https://lcamtuf.coredump.cx/prep/index-old.shtml

To cope with a true emergency, it’s not enough to know the risks and sit on a pile of
survival gear: we need to plan ahead. If your house is on fire, there may be no time to rifle through
folders to gather all your vital documents; if the floodwaters are rising or a chemical tanker overturns
on a nearby highway, it may be too late to start thinking about refueling your car. And if you’re
stranded on a rural road in a broken-down vehicle, you may sorely regret not putting any drinking
water in the trunk.

In fact, even in situations that don’t unfold in such a dramatic way, sketching out a plan can help you
optimize spending and spot potential problems early on. For example, there may be little merit to stockpiling
50 lbs of rice if you can’t possibly store enough water to cook it all. But then, a quick look at the map
may reveal that there is a freshwater reservoir within a
biking distance of your home. Great – maybe all you need is a bike basket and
a pair of spare inner tubes.

So, here’s a bit of homework: make a list of all the threats discussed in this guide that seem to apply to you,
alongside any other contingencies you worry about. For each and every one of them, draft a detailed, step-by-step
preparedness and response plan that sounds right given your life situation.
Don’t obsess over getting all the details right;
we’ll try to refine your choices in section 4, and even then, it may take several iterations to
settle on an approach you are really happy with. For now, simply list all the noteworthy dangers,
jot down some initial answers to the following questions, and see where that takes you.

3.8.1. Threat assessment topic #1: Is it a priority? https://lcamtuf.coredump.cx/prep/index-old.shtml

Do some research to make sure you are not wasting your time on implausible risks. How likely is it that you
would have to face this particular danger, and how much damage can it conceivably cause? For example, do
you live in a 100-year flood zone? In the path of tropical storms? In a high-crime neighborhood?
Be sure to search around and study publicly available resources; reaching out to local emergency response
organizations can be a good plan, too. Try to focus on reputable sources. The science in doomsday movies and
on conspiracy websites seldom checks out.

(If you decide that you don’t care about a particular risk, skip the remaining questions and just move on to
the next problem on your list.)

3.8.2. Threat assessment topic #2: What do you need to be prepared? https://lcamtuf.coredump.cx/prep/index-old.shtml

Do you need to secure any supplies or make other arrangements to prepare for this scenario? If you
need to stockpile items, do you have enough room?
How long would these supplies last in an emergency, and how often would you need to replace them in
storage? Are there any additional steps that you want to take to be in a better place a month,
a year, or five years from now? Make a detailed list and tally the costs.

Be critical of any assumptions you are making in your plan: sure, we’ve seen our share of disaster
movies, but it pays to search for statistics or historical accounts of how such emergencies actually unfold
in real life. Don’t assume that all contingencies are covered by a generic home insurance policy: for
example, earthquake and flood coverage is often sold separately (and costs a lot); and in any case, even
if the insurance eventually pays, you still need a short-term survival strategy to deal with the loss.

When it comes to dangers such as break-ins, fires, or earthquakes, be sure to walk around the house and
take note of anything that unnecessarily exacerbates the risk. Perhaps throwing out old junk,
reorganizing the contents of kitchen cabinets, adding earthquake latches,
or fixing a broken lock would be a better use of your time than ordering space-age
prepper gadgets from Amazon.

For natural disasters common in your region, you can find a lot of relevant (if US-specific) advice on the
webpages of CDC,
FEMA, and the
American Red Cross. You can also have a look at the excellent,
detailed hazard maps available from FEMA, USGS, NOAA, and several other agencies.

3.8.3. Threat assessment topic #3: How and when do you need to act? https://lcamtuf.coredump.cx/prep/index-old.shtml

Think about the exact, step-by-step playbook you would follow: what actions would you need to take and how
much time would you have to carry out the plan? Will you be sheltering at home, or is this a situation
where you need to evacuate? If the answer is “it depends”, what would be the key factors,
and how quickly would you need to make the final call? If you pick the wrong option, how bad would
it be?

Be prepared to make these decisions based on imperfect information. For example, pandemic scares happen
every couple of years – Ebola, Zika, West Nile, avian flu, swine flu, SARS, MERS, and so on – and most of them
fizzle out. In the moment, you don’t know if you’re dealing with the real thing; it follows that your plan
needs to take into account the ambiguity of the situation, enable you to make sound decisions early on,
and manage the fallout gracefully if you make the wrong call.

There is a certain mystique surrounding survivalism, but bugging out is seldom the answer. Leaving your
home and venturing into the unknown puts you at a tremendous disadvantage, so it’s almost always better to
dig in; but if you have to leave, also ask yourself this:

• …where would I go? Crashing with a friend or a family member is vastly preferable to
  camping in the woods. Either way, is the location sufficiently far away to be unaffected by the
  event you’re running away from? If you are driving, will you have enough gas to get there?
  (Again, would it help to have a habit of keeping the tank at least half full?) Are the roads
  likely to be congested or blocked? How many people will think of exactly the same location?
  What are the alternatives if the destination proves to be inaccessible, overcrowded, or unsafe?

• …what do I need to bring? How much can you realistically take with you
  when leaving by car, by bike, or on foot? What are the most important items, and will
  you be able to grab them quickly enough? To simplify things, would it make sense to maintain a
  small cache of supplies in the trunk of your car or at a friend’s place – and if yes, what
  should be in that box?

3.8.4. Threat assessment topic #4: What if you are somewhere unexpected? https://lcamtuf.coredump.cx/prep/index-old.shtml

If you have a daytime job or go to school, there is a good chance that the event you are
preparing for could unfold while you are at that location – or somewhere on the way. Do you need a
special plan to handle this possibility? Can you get back home easily? Do you need water,
food, money, or clothes to make that trip? How likely is it that you would be hurt
or stranded somewhere?

Separately from this, consider the risks of less frequent but more dangerous trips.
If you’re sightseeing or taking a business trip to
a particularly inhospitable or remote destination, what do you
need to survive if, say, you get lost or your car breaks down?

3.8.5. Threat assessment topic #5: Do you need to talk to your family? https://lcamtuf.coredump.cx/prep/index-old.shtml

If you have a spouse, walk them through your plans and make sure they can access the
essential supplies and know how to use them in your absence. If you have children, give them the
very basics as well. For example, in case of a fire, they should know the safest way out
without having to wait for you, and they need to know you won’t be upset if they kick out or cut
a window screen; tell them how to react to home intrusions and medical emergencies, too.

If you are separated from others and need to meet someplace other than home,
make sure that everybody will remember where the meeting point is – and will know
what to do if you can’t make it on time. Keeping some instructions in a wallet can go
a long way.

3.8.6. Threat assessment topic #6: How can your plans backfire or fail? https://lcamtuf.coredump.cx/prep/index-old.shtml

Try to identify the aspects of your plan that are most likely to go wrong, and come up with
viable alternatives. Take a hard look at any new problems you are creating, too:
for example, if you want to store gas in your garage, it will probably help in an evacuation,
but will also increase the odds of accidentally starting a serious fire. Or, consider a
far more prosaic case: if
you are planning to stockpile batteries or bottles of insect repellent, you should make sure
they can’t leak and spoil other, more vital supplies nearby.

3.9. Prepper commandment #9: Plans have flaws, so also write a will https://lcamtuf.coredump.cx/prep/index-old.shtml

People die, sometimes unexpectedly and in silly, undignified ways. Dying is seldom a
pleasant affair and you generally don’t get to choose the “how” or “when”, but you can make
sure that the people who depend on you are going to have the means to get by.

If you have children, a stay-at-home spouse, or any other people who may be dependent
on you, it makes sense to write a will. Even if you don’t have much of an estate to
dispose of, your will can provide instructions for the custody of minor kids,
potentially shielding them from abusive relatives or from foster care. This can be
particularly important for expats, whose closest surviving family members
may be in another country, difficult for the court to pinpoint or communicate with.

In most jurisdictions, to draft a will, you don’t need a lawyer; the only skill that
comes handy is the ability to express yourself clearly and unambiguously. There are
countless state- and country-specific templates available online; in many cases, to
carry legal weight, the will just needs to be co-signed by disinterested parties acting
as witnesses – or cheaply notarized.

Where possible, you should name an executor in the will – a trusted person who will follow
your instructions and take care of the formalities. If you don’t, one will be
probably appointed by the court. This will be costly and may lead to disappointing outcomes.

When writing this document, describe your “ideal” scenario, but also think about all the
complications that may crop up and derail your plan. For example, what if both you and your
spouse die, but your children survive? Or, who should get what share of the money if
your spouse is badly hurt and can’t resume caring for the kids, so they end up in the
custody of a relative? What if your designated executor or custodian is unable or unwilling
to perform the duties? And in an extreme case, if there are no surviving relatives,
do you have any favorite charity?

Of course, for the will to be executed, it needs to be found. It makes sense to keep one
copy in an intuitive location in your home, because that’s where people will be looking for it
first; but if there’s a fire or a flood, that copy may be lost. So, make another witnessed or
notarized copy and give it to the executor or to a close family member who doesn’t live with you.
Some folks don’t recommend creating multiple legally binding copies of the same will, since it
may cause some confusion, but from a disaster preparedness perspective, it’s a smart call.

In many states, even with an uncontested will, it may take many months for the probate process
to be wrapped up. If you are the sole provider for your family, make sure that they
will have the means to survive in the meantime. The right kind of a shared bank account (“joint
tenancy with right of survivorship”) can do the trick; “transfer on death” directives can also
work, and although the process is slightly more involved, it may result in a more favorable
tax treatment. There are several other approaches to this problem, too, but they tend to be
more dicey from the legal perspective – or more costly and more time-consuming to set up.

4. Gear & supplies https://lcamtuf.coredump.cx/prep/index-old.shtml

Yes! That’s the part where he stops blabbing about personal finance and wills, and we all get to
shop for nunchucks and throwing knives!

4.1. Water https://lcamtuf.coredump.cx/prep/index-old.shtml

…Gotcha! But yup, let’s talk about the supplies and tools that may enable you to prepare for
common emergencies in a cost-effective way.

Even with adequate shelter and with limited physical activity, losing access to water means certain
death after a couple of truly rotten days. Thankfully, in the developed
world, this is a very uncommon fate: emergencies that leave communities without potable water are not rare,
but when they happen, the government practically trips over itself to immediately restore service
or to get water trucks on the road.

At the same time, it’s not entirely wrong to worry that in some circumstances, the response may
not come quickly enough; heck, the Department of Homeland Security says that for the
first 72 hours after a disaster,
you may be on your own
and should have enough supplies to survive. The odds of ending up in a real pickle may be modest,
but the stakes are extremely high – and compared to the complexity of preparing to some
other contingencies, the cost of stockpiling some drinking water is practically nil. If nothing
else, when a calamity strikes, you would have one less thing to worry about.

An argument can be made that even in an emergency, potable water is never too far away; after all,
most human settlements have been erected near natural reservoirs: rivers, lakes, or easily
reached underground aquifers. But this is an oversimplification. In
rural areas, water supply can be fairly meager and vulnerable to weather fluctuations and
other cyclic phenomena. For cities, it is true that many of them are seated on the banks of major
lakes or rivers, but suburban sprawl can easily put some residents 10-20 miles away from the
nearest reservoir; on top of that, some of the 20th century settlements in semi-arid and
desert climates rely on water hauled from tens or hundreds of miles away.

Heck, even if you do have a nearby water source, it may take surprisingly little to spoil it: for example,
after an unusually powerful storm, floodwaters can carry toxic sewage from treatment plants and into
rivers and lakes. All in all, stockpiling some amount of drinking water is just a smart,
low-effort prepper strategy, especially in areas with an elevated likelihood of large-scale
natural disasters or industrial accidents.

This brings us to the “how” – and more importantly, “how much”. The average person in the US consumes
somewhere between 50 and 100 gallons a day. A lot of this goes toward uses such as
long showers, laundry, dishwashing, and flushing the toilet – but even if we take out some of the
less essential uses, the minimum consumption that allows us to continue many of the key
household activities is probably in excess of 10-20 gallons a day.
On the other end of the spectrum, the absolute minimum water intake, as estimated by the US military,
is somewhere around one quart per person per day; but note that this assumes no weather extremes, no
substantial exertion, and no immediate hygiene needs.

In the short haul, when all you really need is to stay hydrated, storing about 1.5
to 2 gallons per household member – enough for perhaps up to a week of very judicious use
– should provide a viable if modest buffer for emergencies. Store-bought gallon jugs
are pretty cheap, and easy to squeeze in just about anywhere; if you keep them away from sunlight
and heat, they should last 5+ years before needing to be rotated or thrown out. The main problem
is that they tend to leak, so if you’re unlucky, they may ruin cabinets or wooden floors; if this is a
concern, HDPE gallon jugs or thoroughly rinsed 2 liter soda bottles may be a better bet.

Of course, that’s the bare minimum – but if you have a garage, a basement, or other unused storage
space, I would actually recommend going a bit further and grabbing one or two
5 gallon cans per every household member. Although multi-week water outages are very unlikely,
this simply gives you a more comfortable safety margin: if something goes awfully wrong and
it becomes clear that help is not coming any time soon, you will still have time to look for
alternatives or evacuate. A reserve also puts you in a better situation if it’s unusually
hot or if you have any urgent hygiene needs. The cans are very easy to use: wash them with a
small amount of regular, non-scented laundry bleach, rinse, and fill up with tap water.
Rotate the contents every 2-4 years or so.

If you want to prepare for longer-term disasters, or if you have a large family,
you can make realistic plans only if you live in a single-family home. This
decision alone may give you access to 50-100 gallons of water sitting in the water heater
(unless it’s a tankless design). Next, if you have some backyard or garage space, you may opt for
relatively inexpensive 55 gallon plastic barrels, taking up about as much space a small curbside trash can. Another
common option, costing about the same per gallon stored, is a 275 gallon IBC tote. Such solutions can easily
provide water for an entire family for up to several months, with some
allowance for laundry and hygiene needs. Some preppers stockpile even more – but really, if you
waited this long and the conditions are still dire, it may be high time to hit the road and find
some other place to live.

While home storage of water is not hugely complicated, things get a bit dicey when you have
to evacuate – or if you end up being stranded away from home. If you have a car, your best
bet is to put together a small emergency supplies box that, among other essentials, houses
one or two 1-gallon jugs of water – and keep it in your trunk at all times. But without a
car, your prospects are less cheerful: in case of a widespread disaster, your range will be
severely limited, and even if you take some modest amount of water with you, you will need to
reach a more hospitable location within 1-2 days. A bicycle, a plan, and a good map
will help. A
folding cart or an inconspicuous box of supplies kept at work may be viable choices, too.

As for drinking untreated water: contrary to popular beliefs, in temperate climates, you are
generally not taking huge risks by drinking from a backcountry lake or a creek; if it looks
and smells all right, it’s quite likely fine. On the flip side, a bout of diarrhea due to giardiasis
is probably the last thing you want to experience in such a situation, so it’s good to take precautions
if you can. Boiling your drinking water is a very robust method of eradicating microscopic
wildlife (more about that soon). When boiling is not an option, adding several drops of regular,
old-fashioned
laundry bleach per gallon of water, then letting it sit for 30-60 minutes, will have a roughly
comparable effect. Note that bleach has a limited shelf life; you will need to rotate it every
1-2 years or so. When on the
go, sodium dichloroisocyanurate pills (AquaTabs)
can be more convenient than liquid bleach and work just as well.

There are several other water purification techniques, including iodine, various types
of filters, or even very expensive desalination systems.
The recent Flint water crisis
highlights the value of permanently installed and well-maintained RO units. But for
short-term survival, my take is that most of the filtration systems targeted at preppers
increase costs without offering clear-cut benefits. And really, don’t overthink it: if the choice is between dehydration
and drinking straight from a scummy pond, drink from the pond.

4.2. Food https://lcamtuf.coredump.cx/prep/index-old.shtml

You can survive several weeks without food, but you won’t be having a very good time. Food is
costly, its supply is fairly easily disrupted, and it’s a resource that the government may be
much less inclined to deliver to your doorstep when things go wrong. So, with a variety of
reasonable scenarios to worry about – anything from natural disasters to economic downturns – it
just makes sense to be able to feed yourself even if you can’t buy groceries for a while.

Of course, everybody has some non-perishable food around the house, but it’s much better to create a
dedicated stash: this way, you can count on the supplies always being at hand, and you can stockpile
something more nutritious than stale crackers, a suspect bottle of olive oil, and a rusty can of tomato
sauce. With a well thought-out stockpile of ready-made food, it’s also a lot easier to hit the road.

For short-term survival, the highest priority is just energy – preferably in a form that doesn’t
cost much, lasts forever, requires no preparation, and takes up little space. Generally,
you’re looking at high-sugar or high-fat foods. Some of the common zero-preparation options include:

• High-sugar energy bars.
  Grocery store brands may have limited shelf life, but several prepper-targeted,
  Mylar-packed varieties can last
  5-10 years. Such products are inexpensive (~300 kcal per dollar), convenient, and energy-dense
  (~2,000 kcal per pound). On the flip side, they are probably pretty nauseating as your primary
  food. Imagine living solely off Jelly Bellies for a week.

• Dry survival rations.
  Sold under several brands, including
  Datrex, ER Bar, S.O.S., Grizzly,
  and more. Biscuit-like, less sugary and with a more agreeable taste than energy bars –
  somewhat reminiscent of shortbread. In my book, S.O.S. and Datrex taste best.
  Very inexpensive (~550 kcal per dollar) and should last 5-10 years when stored in a
  cool place. A tolerable choice for short-
  to medium-term nutrition in an emergency. Easy to pack, giving you ~2,200 kcal
  per pound.

• Canned meat, veggies, or fruit.
  Storage life in excess of 20 years (regardless of “best by” dates).
  Tasty, relatively cheap (~200-300 kcal per dollar), and the choice is pretty broad.
  Fruits, veggies, and soups are not very energy-dense (~200 kcal per pound), making them
  impractical for hiking or bugging out; on the flip side, the syrup may provide some additional
  hydration. Meats fare much better, tipping the scales at around 1,500 kcal per pound.
  Canned foods are a good option for longer-term planning, provided that you have enough
  shelf space.

• Freeze-dried dinners.
  Popular with hikers. Extremely lightweight (up to 2,500 kcal per pound) and surprisingly
  tasty. The most reputable brand is
  Mountain House.
  Fairly expensive on a calorie basis (100-150 kcal per $1), but you get a choice of
  raspberry crumble, chicken with dumplings, bacon and eggs, and everything in between.
  Storage life in excess of 15 years. The drawback is that they need some boiling water to
  reconstitute (cold water will also work, but not make a tasty meal).

• Military MREs.
  I don’t find them particularly tasty, but they are popular among preppers.
  A bit on the heavy side (usually around 1,100 kcal per pound).
  Portable warm food with a ton of different menus available – although for the best price,
  you usually need to buy a variety box and can’t cherry-pick. Moderately expensive
  (~150 kcal per dollar). Shelf life around 5-7 years, depending on the manufacturer and on storage
  conditions.

• Nuts and peanut butter.
  At ~3,000 kcal per pound, nuts are surprisingly energy-dense for something that can be eaten as-is.
  Relatively cheap (~400 kcal per dollar). The major drawback is a relatively short shelf life,
  probably not exceeding a year or two. Nuts also do not provide complete nutrition, but that’s only
  a concern in the long haul.

• Vegetable shortening.
  Extremely cheap and energy-dense (2,500 kcal per dollar, 4,100 per pound), making it a unique choice
  when space or money is in critically short supply. In contrast to other common fats,
  store-brought cans of vegetable shortening (Crisco or the like) should stay
  fine for 4 years or more. The product is very bland, but it’s perfectly palatable when spread on crackers, mixed
  with bacon bits, and so forth. It does not provide complete nutrition – but again, that won’t harm you in the
  short haul.

For folks who want to focus on the most plausible risks, I suggest stockpiling dry survival rations
to last around 2-3 weeks; seven 3,600 kcal packets per person should do the trick.
That may sound like a lot, but keep in mind that it may take a while for stores to reopen after an earthquake or a
flood – so it’s not a bad plan to play it safe. And while eating ration bars for a week sounds bland, you may
be in no mood for home cooking when you have to fix a collapsed roof and the utilities are cut off.

For those who are worried about less likely, longer-term contingencies – or who want to limit their future
grocery expenses in case of a financial shortfall – a more varied stockpile to cover 3-4 months is a reasonable
choice. At that timescale, it’s still smart to begin with some number of hassle-free survival rations, but it is
important to complement them with a more palatable menu: freeze-dried or canned meals, MREs, or cheap home-made food.
Crisco aside, some of the nutritious and easily stored staples include Mylar-bagged,
oxygen-scavenged white rice, white flour, dried beans and grains, instant mashed potatoes and oatmeal, pasta, sugar, honey,
powdered milk, salt, spices, and so forth; when stored properly, all of them can last 5 years or more.
Freeze-dried or garden-grown fruit and veggies can add some flavor to your post-disaster cooking, too. Heck, you
can even buy pretty tasty butter,
chicken breast,
canned bacon,
and bread-like Pilot crackers
with 10+ year shelf life (although they are not cheap).

As for the appropriate calorie intake: almost all adults can function normally on 1,500 calories a
day for extended periods of time, although they will slowly lose weight (probably not more than
half a pound a week). If you are skinny or if you’re aiming for surviving many months with no access to other
food, budgeting 2,000-2,200 kcal per day is a safer bet. Since you would have to exercise portion control,
it pays to focus on satiating foods: high-fiber, high-protein, or high-fat.

For hardcore preppers convinced that they may be left with no access to food for a very long time,
it would be also important to maintain a robust intake of protein; somewhere around 40-50 g per
day is believed to be optimal, although you certainly don’t need to observe it religiously.

Ready-made protein-rich foods include some energy bars, most dry ration packets, some
freeze-dried dinners, canned meat, and military MREs; smaller amounts
can be found in some veggies, too. You can also stockpile
protein powder -it’s bland but relatively
cheap ($1 per day).
Freeze-dried scrambled eggs, powdered milk,
and related products, including long shelf life
canned or powdered cheeses and pancake mixes, work
well, too. As mentioned earlier, protein and dietary fiber also have a well-established satiating
effect, helping you maintain a balanced diet – which can otherwise be tricky when snacking on
high-calorie foods. Oh: having some OTC multivitamins may be a good plan, especially
to supplement vitamin C.

Of course, some dedicated preppers worry about even more exotic, post-apocalyptic scenarios
mentioned in section 2.3, basically aiming for indefinite self-sufficiency. I don’t think it’s
a particularly sound concern, but if the prospect of
a civilizational collapse keeps you up at night, I think the options are limited, short of moving
to a rural community
where you could farm, fish, or hunt. Some urban survivalists fantasize about trapping local
squirrels, pigeons, or raccoons – but they would run out of food very fast. Small urban and
suburban gardens are usually difficult to maintain and don’t produce enough to feed a family,
too.

4.3. Fuel and electricity https://lcamtuf.coredump.cx/prep/index-old.shtml

It takes just a single downed power line to knock out your furnace, AC unit, cooktop, refrigerator,
and to make the lights go out; and when such an outage happens due to a larger-scale natural
disaster, repairs can easily take days or even weeks. We think of fuel as a more dependable resource, but
if 1979 is any guide, you only need one
well-timed revolution in the Middle East to make it nearly impossible to fill up a car in some
parts of the United States. Of course, such events are usually inconvenient, not disastrous, so it’s
perfectly fine not to dwell on them in your plans. At the same time, it doesn’t hurt to take a closer
look at what’s at stake – and what the potential solutions may be.

Of all the plausible scenarios, another major oil crisis would probably hit most car-owning families
the hardest, limiting their ability to get food or to take care of other, everyday needs. Generally
speaking, there is no simple fix: keeping a gallon or two in your garage won’t make much of a
difference, while maintaining significant reserves of gas for personal use can be done safely (and
legally) only if you own a large, rural plot of land. Electric vehicles,
especially if charged from rooftop solar panels, can offer a wonderful backup in some parts of
the world, but they carry a very hefty price tag. The best workaround may be the least inspired
one: if you own a car, you can always keep your tank at least half full (a familiar mantra by now),
and have enough food and other essentials to be able to wait out the worst.

A service interruption or a fuel crisis that takes your cooktop out of service for a week or two
is the other hardship perhaps worth worrying about. It’s not just about eating well: in an
emergency, the ability to boil water is one of the best methods of making it safe to drink. While
the owners of rural homes with 500 gallon propane tanks may have little to worry about, the rest of
us would not be having fun. For those who cook using municipal natural gas, a simple backup is a
small countertop electric burner. Conversely, for people with electric ranges, a portable
camping stove and a handful of dirt-cheap
1 lb propane tanks can be a safe, no-hassle choice. A
pound of propane can boil around 12 gallons of water; the entire setup is also very easy to put in a
backpack if you ever need to leave – so it’s basically worth getting either way.

No heating in the middle of a particularly nasty winter can be problematic, too – although it’s mostly a
matter of comfort, not survival. In most places, with robust shelter and adequate clothing, bedding, and food, it’s
fairly hard to freeze to death at home (but note that the cold may make some infections or medical
conditions worse; you may have to worry about frozen water pipes, too). The situation can become a lot more dire if you are on
foot in the middle of nowhere, so truly hardcore, wilderness-minded preppers may have something to ponder about; but
hauling a sufficient amount of fuel is typically impractical to begin with, so their best bet would be warm clothing,
improvised shelter, and the ability to build a fire. We’ll talk about that in the section that
deals with camping supplies.

In some parts of the world, extreme heat can be far more dangerous than cold. When AC is not an option,
it’s usually possible to avoid trouble by staying in the shade, drinking a lot, and limiting
physical activity. If it gets really nasty, the best way to cool yourself is to wet your clothing
and hair, then stand in front of a running fan. You have a bigger problem if you happen to be
stranded in a broken down car somewhere in the middle of a desert – but carrying some water
and several other supplies in your trunk should help a great deal. More about that soon.

During a prolonged blackout, keeping flashlights, radios, and cell phones running can become a
challenge of its own. The most cost-effective approach is to stick to devices that can take
regular AA, AAA, or PP3 (9V) batteries; modern alkaline cells have very long shelf lives (10 years),
can be bought cheaply in bulk, and will do the
trick for almost all portable electronics you can think of. Of course,
modern power-hungry smartphones are a notable exception to this rule. For that, you can always try
solar chargers – they work
well, but are a bit fragile and may not perform too amazingly in wooded areas or on overcast
days. You can also go for
hand-crank generators (fragile and labor-intensive)
or AA power banks (mixed reviews). But
ultimately, also allow for the possibility of not being able to call others for a while.

For powering more serious electrical equipment, a generator is a popular choice for people living
in the backwoods. That said, this option comes with an interesting trade-off: if you were ever
to face a contingency that may last for a longer while, it may be more important to conserve
fuel for driving, cooking, or heating, than to use it for keeping the lights on. A fully-fledged
solar installation helps you
avoid such dilemmas, but costs an arm and a leg. A possible compromise is a jury-rigged
solar setup done at a smaller scale:
if you hook up a 100W panel to a
deep-cycle lead-acid battery
and a low-cost inverter, you gain the ability to
recharge laptops and phones, or even power several desk lamps, a decent-size fan,
or a small refrigerator. The whole contraption costs around $250 and is easy to stow away if
you’re not very short on space.

That’s probably about it… well, all right: this section focused chiefly
on the immediate consequences of an outage, but a severe fuel crisis or a long-lasting power grid
failure would have profound, cascading effects on the entire economy – probably including out-of-control
unemployment, high inflation, product shortages, and more. That said, these are the outcomes we can already
prepare for by other means. As for extreme
preppers who aspire to long-term energy self-sufficiency, I think it’s going to be a
difficult feat: even with a solar installation, under constant cycling, the batteries may not last
much longer than 5 years. Short of finding a cheap Soviet
RTG
on eBay, they may simply have to adapt to living without electricity or gas.

4.4. Electronics https://lcamtuf.coredump.cx/prep/index-old.shtml

Although this may sound very disappointing to a typical geek,
the list of genuinely useful prepper electronics is pretty short. Here’s what I can honestly recommend:

• A large pen drive.

  Computer hardware failures are far more common than space zombies or mutant superbugs.
  Because of this, one of your best investments can be a
  decent pen drive with
  a copy of all your important files; in case of bank mix-ups, throw in copies of
  recent account statements, too. And hey, if want to feel like
  a cyber-ninja – you can always grab a
  copy of
  Wikipedia. It will undoubtedly come handy for rebuilding the civilization, and it’s just 12 GB.

• Flashlights or headlamps.

  Unless you are living in a rural area, you probably don’t need an eye-searing torch that
  chews through ten boxes of batteries in a day. It’s better to get several small, high-quality AA flashlights or headlamps
  that give you at least 20 hours on low power; I’d keep one near your bed, and another
  in your car or in an emergency stash.

• A lantern.

  Not essential, but
  useful for preparing food, dining, reading, and other fun blackout activities where a narrow beam
  would be less comfortable than omnidirectional light.

• An old-fashioned radio receiver.

  A battery-operated AM/FM radio will be a good way to stay in the loop if cell
  networks and the Internet are down, and the civilization is temporarily banished
  back to the dark ages (aka the 90s). A cheap, brand-name model, such as
  Sony ICFP26, will do just fine.

• Handheld FRS/GMRS radios.

  Many preppers obsess about long-distance communications, but in a typical emergency, chatting
  with people 100 miles away is not a priority. In contrast, a hand-held two-way radio
  can be very useful for keeping in touch with your friends and family during any prolonged
  outage. Whenever possible, pick
  a device that accepts the kind of batteries you can stockpile cheaply. Expect a range
  of 2-3 miles in rural regions, a mile or so in the suburbs, and maybe 2-4 blocks
  in high-rise environments – no matter what the manufacturer claims.

  Ham radio is a longer-distance option, but generally requires a license; if you are interested
  in amateur radio, getting a Technician class license in the United States is
  fairly straightforward and costs around $15, but
  requires you to spend 8-10 hours memorizing answers to questions – some useful, some not. With all
  that said and done, ham radio can help you coordinate local response to more substantial emergencies,
  together with local volunteer members of organizations such as ARES or RACES. For personal
  communications, handheld 2m radios tend to have a slightly better range than GMRS, but the real perk is being
  able to buy a stationary or car-mounted transceiver, or to use a repeater, for considerably greater reach
  – from 20 to 200 miles, sometimes more.

  (I have some in-depth notes about handheld radios
  here.)

• A thermometer that won’t run out of juice.

  Responding to serious emergencies can be stressful and physically taxing, making it easy to catch
  nasty infections along the way. To know how bad things have gotten, it’s good to have a reliable way to
  take body temperature; keep in mind that many low-cost axillary thermometers use LR41
  batteries, and that you probably don’t have any spares lying around. A traditional glass
  thermometer will also work, but is more fragile.

• A small space heater and a fan.

  Sometimes useful for coping with temperature extremes. Decide for yourself if you
  need it. If yes, pretty much any make and model will do.

• A dashcam or a security camera for your home. We’ll talk about these later on.

Except for flashlights, don’t keep any batteries in your emergency electronics, as to minimize the danger of an electrolyte leak messing up the device.

Of course, there are many other high-tech gadgets popular among some of the more affluent
and paranoid preppers
– anything from satellite phones, to night vision goggles, to heated insoles. In all
likelihood, none of that is worth the cost. If I had to pick two extravagant
“doomsday” accessories that could conceivably be useful to some people if something
truly awful happens to the world, I’d go with
a waterproof hiking GPS unit and a portable Geiger counter. Both
can be powered by AAA/AA batteries and cost under $200. (We’ll talk about Geiger counters
and their relative merits a bit later on.)

Inspired by science fiction books and a handful of real-world incidents, some
hardcore survivalists worry that their portable electronics or vehicles could be
disabled by EMP weapons
or solar flares. The concern over solar flares is misplaced; the threat of EMP is a tad
more valid, but even if EMP warfare came to pass, small electronics and quasi-shielded automotive
circuitry would probably not be permanently affected by anything other than a
close blast. Power plants and transmission lines are a different story. Heck, in 1989, solar
flares knocked out a good
chunk of the Canadian power grid. Still, for that, a surge protector works better than tinfoil.

4.5. Essential tools https://lcamtuf.coredump.cx/prep/index-old.shtml

While not all urban-dwelling readers may be particularly interested in DIY work, there are times when
it’s hard to call a handyman. So, almost every home will benefit from having a well-maintained “emergency”
toolbox containing several items useful for performing basic repairs and dealing with other minor incidents:

• A cheap pocket knife,

• A basic, no-frills multitool,

• A small adjustable wrench,

• At least 100 ft of paracord or UHMWPE rope,

• A big roll of duct tape,

• A rudimentary sewing kit,

• A decent pen or a mechanical pencil,

• A pack of writing pads,

• Sharp, large scissors,

• Needle-point tweezers,

• A compact but sturdy hammer,

• A box of 1″ nails,

• A usable can opener,

• A sealed bag with disposable lighters or several boxes of matches.

Having a medium-size bucket at home is a
must, too. If you own a bicycle and are expecting to use it in emergencies, it would be wise to
throw in a bike tool,
several tire levers,
a patch kit,
one or two spare tubes,
and a portable pump.

Finally, for those who are worried about the decidedly unlikely prospect of having to escape home
and fight off radscorpions in the wilderness, a
lightweight hatchet, a comfortable saw, a larger fixed-blade knife, a folding shovel, a
compass and some matches or a lighter in a waterproof container
can come handy in several ways.

A subset of this is also worth keeping in a car. It’s not just about zombies or life-and-death situations:
if you hit something in a parking lot and your bumper cover comes off or your liftgate won’t stay
shut, it’s nice to be able to tie it down and get back on the road. Similarly, a shovel can help you
get back on the road after getting stuck in snow or mud. But speaking of survival: a pocket
knife, kept within reach (e.g., in the center console), can be used to cut
seat belts if you get into a wreck; and in a pinch, it will double as a self-defense tool.
Belt cutters can also fulfill that first task,
and may be easier to operate if you are hurt – although they are less useful for other purposes.
I’d also
recommend getting an automatic center punch –
it’s a neat $5 tool that effortlessly shatters tempered glass (i.e., side and rear windows) when
the doors won’t budge. It works way better
than many of the specialized car escape devices sold on the Internet.

If you own a house, especially in a region prone to earthquakes or tropical storms, you should
probably have a sledgehammer, a chainsaw (with a charged battery or some fuel at hand), bolt cutters, and
a pry bar. These heavy tools are essential for clearing debris and getting to whatever’s underneath. Keep
them far from your other supplies: if your primary stash gets pinned under other junk, you can use the tools
to get it out. Don’t store pry bars and similar equipment in plain sight; robbers often use found
tools to force patio doors, to pop safes, or
worse.

No matter where you live, it’s also nice to have some materials at hand to patch up broken windows on a stormy
night. Window security film can be used to keep broken
glass in place, while a roll of thick plastic sheeting or tarp from a hardware store can come handy for temporary
repairs; space permitting, you may also want to keep several wooden planks. For suburban and rural homes in regions
prone to extreme weather, pressboard and sandbags may be worthwhile, too.
Traditional sandbags tend to be extremely labor-intensive to fill, so plan accordingly;
water-filled barriers (Hydrabarrier) are much easier to deploy, but cost more.
Absorbent sock-style barriers can be used to deal with
minor flooding, but only up to an inch of water or so; they may be less useful for inclement weather,
but may prove indispensable for dealing with backed-up sewage or similar ills.

And now, for something completely different: during a longer water outage, you won’t be able to flush your
toilet – a little-appreciated but grave hygiene risk. When living in a single-family home, you should probably
get a shovel and a pickax: they are useful in the backyard either way, but if push comes to shove, such tools
allow you to dig out a latrine and address the sanitation problem in a fairly sustainable way. Of course, dumping
bagged human waste into trash will work for a while, too, but it quickly becomes a liability.

(Folks living next
to a pond or a creek, or who have a rainwater collection system, might be able to use this for flushing; but hauling
gallons upon gallons of water for flushing from a more distant location is bound to get old quick.)

4.6. Camping equipment https://lcamtuf.coredump.cx/prep/index-old.shtml

Many hardcore preppers spend their time fantasizing about heroic survival in the endless, pristine wilderness,
equipped with nothing more than a bug out bag, a trusty rifle, and their own iron will.
But even in far more realistic situations, being able to set up a camp can be a valuable skill. During mass evacuations,
there is always a good chance of being stuck on a congested highway for a day or two, or reaching your destination only
to find out that all the hotels and motels are full. The benefits are clear for some
small-scale emergencies, too: if backed-up sewage makes your home uninhabitable for a while, setting up a tent
in a friend’s backyard can be much cheaper than staying in a hotel for several weeks.

Above all, the nice thing about it is that camping gear doesn’t need to just sit in your closet, collecting dust
on the off chance that something bad may happen a decade from now. You can simply grab it
and head out for the weekend every now and then; camping is fun, doubly so for kids. It’s also a great opportunity
to test some of your other equipment, and spot potential flaws in your preparedness plans.

Especially if you’re living in the suburbs or in the countryside, I recommend having the following items
at hand:

• Maps.

  Essential for finding hospitable destinations, getting there, and finding alternative routes if something goes
  wrong. I suggest getting both a country road atlas and a more detailed map of your county or state. If you have
  a car, just keep them there – they may also come handy if you get lost and your cell phone dies.

• Weather-appropriate clothing.

  A well-maintained stash of warm clothes, including
  waterproof ponchos and rain boots. In a pinch, you can also use
  metallized Mylar blankets: tie them with some
  tape to make improvised rainproof, windproof, or thermally insulating clothing and hats, shoe liners,
  and more.
  The blankets cost very little and take up virtually no room, so I strongly suggest keeping some in your
  car. If you’re stranded in an inhospitable place, they could save your life.

• Shelter.

  The usual combo is an appropriately-sized, waterproofed tent, a set of sleeping bags & pads, and possibly
  some compressible or inflatable pillows for comfort.
  In cold weather or during heavy rainfall, it’s also possible to shelter in your vehicle, with Mylar blankets
  serving as a substitute for sleeping bags; and on a hot day, the same material and some rope can be used
  to improvise a shade. Again, the blankets are worth having in your car at all times.

• Food prep gear.

  As discussed in section 4.3, one of the best ways to cook food
  or to sterilize drinking water on the go is to have several portable propane tanks,
  a miniature stove,
  and a lightweight covered pot. Some plastic dinnerware can be
  a nice touch.

  Make sure that the stove fits your propane tanks; you may need a Lindal valve adapter if not.

• Mosquito repellent.

  Yep. End up in the wrong part of the woods and these bastards can suck you dry. Go for
  40% DEET 20% picaridin. Actually, get both.

Of course, there is also the luxury option: buying a camper or an RV. Such vehicles are frowned upon
in many cities, but if you are in a rural area, if it’s within your budget, and if you can see yourself
using it regularly, go for it – and don’t look back.

4.7. Hygiene, health, environmental protection https://lcamtuf.coredump.cx/prep/index-old.shtml

Humans are pretty fragile. In many of the more serious scenarios discussed in this guide, your
survival or well-being may be critically dependent on the ability to deal with incidental medical
emergencies, to curb the spread of communicable diseases, or to maintain sanitary conditions at home.

Of course, there are situations where prompt medical attention is simply a necessity; for
example, although it may be theoretically possible for an untrained enthusiast equipped with
an anatomy handbook to perform appendectomy, the odds of the patient surviving are pretty damn
low. That said, outside the domain of major surgery, the outlook is not necessarily as grim –
so even when professional help is not available right away, not all hope may be lost.

4.7.1. Health & hygiene topic #1: Basic cleaning supplies https://lcamtuf.coredump.cx/prep/index-old.shtml

Before we dive into heady stuff, let’s talk good housekeeping!

It pays to be prepared for nasty spills or sanitation emergencies. In addition to some of the tools
discussed in earlier chapters, a good starting point is a large box of 13 gallon
trash bags,
another box of thick, 42 gallon contractor bags,
a set of disposable nitrile gloves,
some rubbing alcohol, and a bottle of regular laundry bleach. Rubbing alcohol is an excellent
solvent and a rapid-evaporating disinfectant; bleach is a potent, long-lasting biocide and
a great odor neutralizer. Oh – as noted earlier, an
absorbent sock-style barrier may
be useful for containing particularly nasty spills, too.

When it comes to comfort and personal hygiene, I would also suggest stockpiling a carton of toilet paper, a
pack of old-school soap bars, a bottle of
no-rinse body wash and shampoo (to conserve water), some antiperspirant,
toothpaste and a toothbrush, nail clippers or scissors, and several disposable razors. At home, such items
can come handy only during prolonged emergencies; but as a part of your in-car kit, they are invaluable if you
are ever stuck somewhere or forget to take your toiletries with you on a camping trip.

As mentioned earlier, water outages can create an unpleasant problem with the disposal of human
waste. While a bucket with a trash bag can be used as an impromptu toilet, to keep the conditions
sanitary, some form of waste treatment is a must. A cheap option is pouring a layer of
clumping (bentonite-based) kitty litter over it after every use; other budget solutions include
cement and lime. More expensive choices are gelling agents and RV waste digestants.

Laundry is another (if slightly less pressing) problem that many preppers may have to reckon with.
Well-chosen antiperspirants and BZK-based antimicrobal sprays
do wonders to control bodily odors and extend the life of undergarments.
Beyond that, careful hand-washing and rinsing techniques help minimize waste – but when there is
no running water, doing laundry is still going to be a rare luxury for most.

4.7.2. Health & hygiene topic #2: Visibility on the road https://lcamtuf.coredump.cx/prep/index-old.shtml

In addition to assorted tools and hygiene supplies, your car kit should probably include
a high-visibility vest; if your vehicle gives up
life, it’s better to be visible when trying to revive it or walking to get help. I’m less convinced about
the benefits of carrying flares or flare guns; while they can be useful in serious emergencies, they
also pose some fire risk.

4.7.3. Health & hygiene topic #3: Medical education https://lcamtuf.coredump.cx/prep/index-old.shtml

Before you even think about self-medicating or treating wounds, you should get a reasonably systematic
understanding of emergency medicine. I recommend getting
“Wilderness Medicine: Beyond First Aid”: it
is accessible, focuses on situations where diagnostic and treatment facilities are limited, and
goes well beyond the basics. Just as importantly, it avoids weird spiritual, homeopathic, or
naturopathic claims that often creep up in prepper books.

Two other publications I can recommend are
“Where There is No Doctor” and
“Where There is No Dentist” by the
Hesperian Foundation.
They pay less attention to contemporary meds or nuanced emergency procedures,
and spend more time on holistic, community-oriented care for practitioners in some of the most
impoverished regions of the world. This probably makes the publications worthwhile for
hardcore preppers who worry about widespread, long-term cataclysms.

Now, even after reading all these, don’t get too cocky: there are good reasons why it takes about
10 years to become a doctor, and why it involves not just reading a book or two, but also dissecting
cadavers and watching other medics at work. When trying to render medical aid, not understanding the limits
of your knowledge can literally kill.

4.7.4. Health & hygiene topic #4: Common meds https://lcamtuf.coredump.cx/prep/index-old.shtml

When living in squalor conditions and running short on supplies, even seemingly prosaic medical conditions can
become life-threatening. For example, in less developed countries, otherwise non-lethal diarrheal
diseases cause almost 2.5 million deaths every year. The reason is simple: without proper care,
the disease makes it easy for the victims to
get terminally dehydrated or succumb to severe electrolyte imbalance.

And it’s not all about dying, too: a nasty toothache or a debilitating allergy can make it very
difficult to stay productive and alert. With all that in mind, my list of essential and easily available
prepper medicines includes
ibuprofen (pain relief),
cetirizine (allergy management),
amoxicillin (broad-spectrum antibiotic),
loperamide (anti-diarrheal),
meclizine (prevents vomiting),
miconazole nitrate (treats fungal skin infections),
bacitracin ointment (bacterial skin infections),
topical lidocaine (anesthetic), and
hydrocortisone cream (anti-itch).
For disinfecting your hands and cleaning wounds,
benzalkonium chloride wipes can work pretty well;
for burns, many people swear by
hydrogel dressing or creams, too.
Finally, for treating severe dehydration, try
oral rehydration packs.

Manufacturers’ expiration dates on all meds are very conservative, but even the US
government
intentionally
ignores them for its stockpiles of shelf-stable drugs. As far as I can tell, when stored in a
fridge, all of these products should be good for 5+ years.

Of course, if you need any prescription meds to survive, try to get a reserve. Except for
the case of narcotic painkillers, most doctors should be quite willing to help. In contrast to
the shelf-stable substances discussed earlier on, be very careful with expiration dates if your
stockpile includes any easily perishable drugs (say, insulin).

A handful of OTC dietary supplements may be useful for treating some chronic conditions
in situations where prescription drugs are not available – but if you want to
learn more, be prepared to wade through a sea of low-quality research and outright
quackery. Preliminary but somewhat plausible
findings include the apparent antidepressant properties of saffron and fish oil,
the beneficial effects of curcumin on some types of chronic pain, or the
utility of berberine and salacia reticulata in managing type 2 diabetes. Again, tread carefully;
examine.com is a good starting point for getting the data behind some of the claims.

Ah, one more thing: for you car kit, I recommend getting some ibuprofen and
caffeine pills. Sure,
if you are getting sleepy, you should pull over and get some rest – but if you really can’t,
caffeine can help you stay alert. Note that it’s possible to overdose; the symptoms are
typically just very unpleasant, but in rare cases, can be life-threatening.

4.7.5. Health & hygiene topic #5: Dental emergencies https://lcamtuf.coredump.cx/prep/index-old.shtml

Blame modern diets, blame our longevity, or blame the mistakes of mother nature – but the bottom line is that for most humans,
dental problems are a question of “when”, not “if”. And when excruciating pain strikes at an inopportune time, it’s really no
laughing matter: in absence of adequate medical care, tooth problems have been known to push some people to the verge of suicide.

Unfortunately for preppers, the management of serious pain in an emergency situation is tricky: virtually all the
potent painkillers have narcotic properties and are very illegal to buy or possess without a prescription. Fixing the
underlying tooth problem can be similarly elusive: you need expert knowledge and a collection of expensive and bulky
tools: high-speed drills, suction units, and so forth. In the end, the best preparedness strategy is just prevention:
take good care of your mouth and stop by for a routine checkup at least once a year.

Of course, while this approach reduces the odds of being blindsided by a painful problem, it does not make the risk go away:
a chipped tooth or a painful abscess can strike with virtually no warning. If you can’t see a dentist right away, OTC painkillers
can offer partial relief, but no amount of ibuprofen will let you forget about an exposed nerve. Topical
benzocaine ointments may work better in some situations, but they don’t
last very long. Sometimes, swishing some cold water in your mouth, or sucking in air through a carefully positioned straw, can offer
decent relief. In the longer haul, amoxicillin can clear up many dental infections, while
zinc
oxide / eugenol cement can be used for emergency repair of damaged teeth. There are some reports that repeated treatments of
cavities with
silver nitrate
can be beneficial, too – but be aware that the substance is caustic and tends to semi-permanently stain skin (and anything else it
comes into contact with).

4.7.6. Health & hygiene topic #6: Hemorrhage and wound management https://lcamtuf.coredump.cx/prep/index-old.shtml

Severe bleeding is one of the major causes of death following an injury. It’s an emergency
on its own, and knowing how to manage it until help arrives can make all the difference between
life and death.

A decent hemorrhage kit should probably include a generous amount of bandages (3M Vetrap is particularly convenient),
a tourniquet,
clotting gauze, and some duct tape.
You should read the manuals and consult an up-to-date first-aid guide, but the basic
idea is to apply lots of pressure to any profusely bleeding wounds. This can be done
with bandages, clothing, duct tape, or even your elbow, knee, or hips. Clotting gauze or sponges,
when pushed into the wound cavity, can help stop bleeding more quickly and stabilize the
victim. Tourniquets used to be frowned upon in the past, but when dealing with major
trauma to a limb, they sure beat bleeding out to death; it’s just that they cause some
tissue injury, and if kept on for too long, necrosis may set in and the limb may have to go.

Don’t just keep that stuff in your home; it’s actually more important to have such a kit in your car (ideally in
the center console) and carry something equivalent when biking, hiking, climbing, hunting,
or engaging into other injury-prone sports.
There are some lightweight ready-made kits that may do the trick, although making your own is always a better choice.

In addition to such immediately necessary supplies,
some prepper guides recommend purchasing sutures, along with tissue forceps and hemostatic clamps.
Such equipment may be useful for neatly closing major wounds in situations where bandages won’t do –
but suturing correctly requires a fair amount of practice and know-how.

For gnarly cuts,
skin staplers or skin closure strips (necessarily with benzoin swabs)
tend to involve less hassle – and are harder to mess up.

For longer-term wound management, in addition to hydrogels and benzalkonium chloride disinfectants
discussed earlier on, there is some utility to
non-adherent dressing and ABD pads. In a pinch,
when dealing with high-drainage wounds, sanitary pads should also do the trick.

4.7.7. Health & hygiene topic #7: Broken or crushed limbs https://lcamtuf.coredump.cx/prep/index-old.shtml

Your emergency medicine book will go into more details about setting bones, applying splints,
or even doing field amputations with a knife and a saw. But even just to deal with a sprained ankle, a
folding cane may be good to have somewhere in your
stash. Beyond that, bandages are useful for improvising splints; in areas where improvisation may be
difficult – say, in the desert or up in the mountains – portable folding splints (SAM splints)
can be handy, too.

4.7.8. Health & hygiene topic #8: Respiratory and environmental protection https://lcamtuf.coredump.cx/prep/index-old.shtml

When it comes to transmittable diseases, your best bet is avoiding exposure: if there’s something really
nasty making the rounds in your community, stay home – or at the very least, avoid public transit, cancel non-essential
air travel, and avoid other crowds. This includes grocery stores, farmers markets, restaurants and bars, concerts, sports events,
and non-essential trips to healthcare facilities. Under such circumstances, online delivery is vastly preferable to doing groceries
in person, but if that option is not available, it’s best to do shopping off-peak – say, 6am or 11pm.

With all that in mind, despite numerous misconceptions, properly-worn N95 masks probably provide adequate protection against most
airborne diseases. The other major transmission vector is hand contact, so don’t touch other people,
avoid public-use surfaces, and resist the instinct to touch your face without first washing
or disinfecting your hands (we subconsciously touch our faces a lot more frequently than we suspect).

Because a restroom is not always within reach, and contact with door handles or grocery carts can be difficult to completely avoid,
buying some hand sanitizer to put in your backpack, purse, or in your pocket, is a pretty solid plan. Hand sanitizer by the door
also helps establish a routine where the entire family can clean hands immediately after entering the house, without waiting for
the bathroom and possibly touching other items on the way.

Similarly to respirators, hand sanitizer sells out quickly during pandemic scares – but if you miss that train, you can make your own from
rubbing alcohol, water, and a commonly-available gelling agent such as methylcellulose.
Disposable gloves may be a viable alternative in some scenarios, too.

If you worry about releases from chemical plants or overturned ammonia tankers,
3M multi-gas cartridges and half facepieces may offer robust protection when sized
and fitted properly. That said, in most cases, it’s more important to develop a plan for sealing your home;
walk around and take note of any crawl space inlets, bathroom and kitchen exhausts, chimneys,
fireplaces, and any other gaps. In an emergency, you can cover them with trash bags and duct tape.

Although we are entering the realm of extremely unlikely events, if you genuinely worry about
encountering an overturned chemical tanker while driving down the highway,
3M 5512 escape respirators offer decent short-term
protection against many threats. In addition to low price, their major advantage is their small size; you
could conceivably have one for every occupant, and just store that gear in the vehicle.

Of course, some extreme preppers will settle for nothing less than a military-grade gas mask rated for
chemical, biological, and nuclear warfare. While it is true that such masks offer much better protection
against nerve agents and similar extremely harmful substances, it’s not a likely concern in most parts
of the world – and either way, it’s doubtful that you would have enough time to suit up once the symptoms
kick in.

On a perhaps more realistic note: since many of the common and harmful industrial gases are highly
water-soluble, breathing through a wet towel or other moist piece of cloth, or draping it to form a
tent over an infant’s car seat or a stroller, might offer some very short-term protection when
all other options fail.

4.7.9. Health & hygiene topic #9: Vector control https://lcamtuf.coredump.cx/prep/index-old.shtml

In some parts of the world, mosquitoes, flies, and other biting insects are major vectors for extremely
serious diseases, such as malaria, African sleeping sickness, dengue fever, or lymphatic filariasis. The same is not
a grave concern in more temperate climates; although malaria used to be a problem in some of the southern states,
it has been eradicated since 1951. Today, some of the most serious incidents in the US and in Europe are the occassional
cases of Lyme borreliosis or the West Nile virus.

Still, if you are worried about the situation changing for the worse, repellents such as DEET and picaridin can
provide the first line of defense. Beyond that, more radical solutions may include
electric bug zappers
(especially when coupled with mosquito attractants, such as octenol or lactic acid),
permethrin insecticide sprays, mesh jackets,
window screens,
and bed nets. For crawling insects, borax and
diatomaceous earth can act as a deadly barrier, too.

While serious zoonotic diseases can be also spread by birds, rodents, or even cats and dogs, such vectors
are more easily controlled or avoided by maintaining sanitary conditions at home; in extreme cases,
traps or poisons such as bromadiolone may do the trick, but unless you are living in a place prone
to infestations, I wouldn’t worry too much.

4.7.10. Health & hygiene topic #10: Dealing with nuclear fallout https://lcamtuf.coredump.cx/prep/index-old.shtml

There are quite a few pop culture myths surrounding the dangers of nuclear incidents, contributing to a defeatist attitude
among even some of the most hardened preppers. But in reality, such events are a lot more survivable than portrayed in
fiction – and perhaps more importantly, the world that awaits the survivors would not necessarily be all that bleak. A good way to explore this topic is a book titled
“Nuclear War Survival Skills”. It sounds goofy, but it’s been written
by the folks who worked on the Manhattan Project, and is as close to scientific truth as you can get; plus, it is not copyrighted
and can be downloaded for free.

To summarize, let’s start with the eponymous threat of nuclear war. A typical ICBM strike is likely to kill most people within a 1 to 10 mile
radius of the explosion, with most perishing due to the blast wave and intense heat, not gamma rays. In fact, contrary to popular lore and
as witnessed in Hiroshima and Nagasaki, when one sees a flash of light, ducking behind cover is quite likely to save their life. It’s also
important to remember that even an “all out” nuclear exchange with another superpower would leave most of the United States unscathed.
It would not turn the planet into a post-apocalyptic wasteland – not any more than the hundreds of nuclear tests conducted in the
twentieth century.

The fallout threat tends to be overblown, too. For one, air bursts, which are preferred because of their improved blast radius,
do not produce that much of it; far more tends to be released during nuclear power plant meltdowns or ground bursts.
In any case, whatever gets kicked up in the air can travel hundreds of miles before settling down. So, in the aftermath of
an incident, getting indoors and sealing your home should be your first instinct. Basic respiratory protection can help, too.

At first, the falling dust will be extremely radioactive and even short-term exposure might be lethal – so your best bet
would be to seek shelter in the basement, or near the center of mass of any other building. This maximizes the mass between
you and the outside world, shielding you from the gamma rays produced by whatever happens to settle on the roof and the outside
walls. The density and volume of the shielding material matters more than anything else. It does not have to be lead; mattresses
and bulky furniture should do.

Luckily for the survivors, the highly radioactive isotopes present in the fallout are also very-short lived; the intensity of radiation
will likely drop ten-fold within 6-8 hours, and will decrease a hundred-fold within two days. If you wait a week or two, it
should be quite safe to venture out. Of course, it’s still best to stay indoors for as long as possible, and when heading out,
it’s good to keep the trips short, to wear disposable coveralls, and
to take care not to track any residues into your home. But you don’t need to lock yourself in an underground vault for a decade or
two.

This brings us to an interesting question: if the radioactivity decays so quickly, why aren’t people moving back to
Fukushima or Chernobyl? Well… save for several small hotspots, the exclusion zones are safe to walk around,
but it can be more dangerous to drink contaminated water or eat local wildlife or crops.
Our body may end up using some of the longer-lived radioisotopes as biological building blocks – which would expose us
to low-grade radiation, at an extremely close range, for the rest of our lives. While it is usually not a death
sentence, this phenomena is bound to produce a measurable spike in mortality across any sufficiently
large population. It is more humane and more socially acceptable to keep people out.

Still, this does not mean that the survivors of a nuclear war would have to choose between starvation and poisoning.
Water and food stored in closed
containers will not become radioactive – people would just have to be mindful of the dust on top. Crops can be grown after removing
several inches of topsoil, and most rivers, streams, and creeks become safe quite rapidly (shallow bodies of standing water are a
different animal). In other words, with basic precautions, it’s quite possible to thrive in the aftermath of even the
worst nuclear war. All it takes is some luck and a bit of knowledge; blast-proof bunkers are not a must.

In fact, one of the more consequential health consequences of nuclear accidents is also very easy to manage: it’s the release of
copious amounts of radioactive iodine, a short-lived substance that gets absorbed by the thyroid gland. To deal with this
issue, people in the affected areas are typically offered potassium iodide pills; this temporarily saturates
thyroid and prevents any further uptake of iodine for a couple of days or weeks. Such tablets are
available over-the-counter and dirt cheap, so
it’s not a bad idea to have some at hand.

Other than that, there isn’t much that can be done to limit the damage caused by serious exposure to radiation. Some animal
studies suggest that pyrroloquinoline quinone (PQQ), an OTC dietary supplement, can have fairly pronounced
radioprotective benefits. While the evidence is very preliminary and the quality of the studies is lacking, the substance is believed to be pretty safe,
so you can certainly
grab some just in case. Another potentially beneficial
OTC products along the same lines
are diindolylmethane (DIM), n-acetylcysteine (NAC), pyrroloquinoline quinone (PQQ), vitamin C, and melatonin.

With all this out of the way, let’s get back to a gadget mentioned a bit earlier in this guide: Geiger counters.
Unless you’re an emergency responder, you may not really need one. That said, such a device could conceivably
help you stay informed and keep your family and friends at ease – and I don’t mean just the remote possibility of
a nuclear war. Consider all the bogus rumors of contaminated
water and food in the aftermath of Fukushima; a radiation meter could have put any such speculation to rest.

Of course, to use a Geiger counter effectively, you need to know how to interpret the results. Although some
controversy exists, the prevailing view is that the effects of radiation are cumulative in a fairly linear fashion;
here’s what you can expect once you hit a particular dose:

• 100 mSv (millisieverts): no immediate effects. A marginal but measurable increase in
  the likelihood of developing cancer later in life (+0.5%). This dose was
  received by a handful of residents during the Fukushima disaster in 2011.

• 1 Sv: mild radiation sickness and a substantial increase in lifetime
  cancer risk (around +6%). A dose that might have been
  received by some subset of residents near Chernobyl in 1986.

• 2 Sv: severe radiation sickness with vomiting and hair loss. Dangerous
  but with good chances of survival. A pretty substantial risk of cancer down the line (+12%).

• 5 Sv: typically lethal, although there is a chance of recovery with
  proper medical treatment. Survivors are highly likely to develop cancer later on.

• 10+ Sv: nearly always fatal. A dose received by some of the first responders
  at Chernobyl.

Some Geiger counters can keep track of the cumulative dose for you, but most will
simply display the rate at which you are getting exposed – typically in microsieverts
per hour (µSv/h) or microroentgens per hour (µR/h; for gamma radiation,
1 R/h ≈ 1/100 Sv/h).
To figure out what the reading means, you need to do the math: for example, at 600 µSv/h,
you will hit 100 mSv within a week, and 1 Sv within about two months. (The usual background
rate from natural sources hovers around 0.1-0.2 µSv/h.)

For folks interested in getting a nice, compact Geiger counter, Radex One
is pretty hard to beat;
it is tiny, inexpensive, and can be hooked up to a PC to continuously monitor the environment (and send e-mail or SMS alerts).
The one caveat is that similarly to many other low-cost units,
this device maxes out at 1 mSv/h – enough to know that something is very wrong, but not enough to tell if
you’re going to receive a life-threatening dose in an hour or somewhere within the next six months. In other words, some of the more hardcore
preppers may want to invest in a more capable unit, such as ADM-300 (which goes all the way to 100 Sv/h) or RAD-60R (3 Sv/h).
Decommissioned military and civilian devices in excellent working condition can be found on eBay for around $200.

4.8. Self-defense and personal security https://lcamtuf.coredump.cx/prep/index-old.shtml

As discussed earlier in this guide, we face surprisingly high lifetime odds of becoming victims of
burglary, assault, or other major crime. To deal with this danger, the guide promotes a handful of passive
risk avoidance and loss minimization strategies, with the bulk of this advice found in section 3.5.
But it would be dishonest to claim that such methods will always shield us from harm – so in this
chapter, let’s have a look at some of the tools that serve as the last line of defense when
all other approaches fail.

4.8.1. Defense topic #1: Protecting your personal property https://lcamtuf.coredump.cx/prep/index-old.shtml

It is fiendishly difficult to safeguard your belongings when you’re not home. When dealing
with opportunistic burglaries, a heavy, bolted-down safe, ideally ordered directly from a reputable
manufacturer, is probably your best defensive tool. Against sophisticated adversaries on a
targeted job, almost all bets are off; in such cases,
operational security (section 3.5.3) is more important than any amount of high-tech gear.

Now, when asked about the best way to make a residence burglar-proof, most people would
probably mention getting an alarm system. But alarm systems are fairly weak deterrents
against theft; most statistics suggest that they reduce the likelihood of a break-in
by around 50%. So, do the math: take the costs of installing an alarm system (probably around
$2,000 for a comprehensive solution), plus the ongoing monitoring fees (easily $200-$500/year),
and then contrast these numbers with the likely loss in case of one or two break-ins over the
next several decades. Keep in mind that even if the numbers are favorable, a high-quality safe
($500+) may still be a more cost-effective approach.

Alarm systems aside, cameras are another popular security tool. They do relatively little to
deter theft, but can document all sorts of problematic encounters – and in the event of a burglary,
perhaps improve the odds of recovering stolen goods.
Decent wi-fi cameras start at $100 a piece; many models can record to a local SD card, although
having a centralized DVR unit, ideally stowed away in an inconspicuous place, will
make the system more robust.

Some preppers advocate “hardening” the perimeter of your home. The returns on this investment will
vary; for example, high-security locks and reinforced doors may be worthwhile in high-rise
apartment buildings, where the front door may be the only way in. For single-family homes, the
burglars will probably not bother with the locks at all; forcing open a bathroom window takes
much less work. Tall fences and locked backyard gates can help, although their benefits are
limited in rural areas or in shady neighborhoods.

The other tools worth mentioning here may be remote motion detectors, such as
passive IR monitors or beam sensors. They won’t do squat
when you’re not on premises, but when you’re home, they can give you an advance warning
about unwanted visitors. It’s a remote concern, but the sensors are relatively cheap, so
just do what feels right.

As for cars: there is no hope. Don’t leave anything of substantial value in the vehicle, and
if the car itself is valuable, have it insured against theft (setting your deductible to $1,000
or more keep the premiums low). Avoid tempting the thieves
in any way: countless car windows have been smashed over a $5 bill and some coins left
in the cup holder. Put spare change somewhere else.

4.8.2. Defense topic #2: Limiting liability for car accidents https://lcamtuf.coredump.cx/prep/index-old.shtml

Vehicular accidents are depressingly common; while defensive driving can limit your
risk, the possibility of injuring another person or causing property damage never really
goes away. When you are involved in a car wreck in unclear circumstances, or when your
statements do not match the words of another driver, video evidence may be the best way
to escape criminal charges or to resolve civil claims.

It used to be that dashcams were prohibitively expensive; but today, the prices
start at $50, so it makes sense to give the devices a try. I can recommend
Rexing V1, but there are
countless other options to choose from. The bottom line is, if you own a car, it’s
probably the most affordable and meaningful liability insurance policy you can get.

4.8.3. Defense topic #3: Fighting for your life https://lcamtuf.coredump.cx/prep/index-old.shtml

In theory, a person’s natural right to self-defense is broadly recognized in much of the
western world – but in practice, different societies look at it in very different ways. Today,
in much of Europe, the very notion that one private citizen could lawfully harm another human
being is met with suspicion and distaste; the control over life and death is more willingly
delegated to the agents of the state.

These differences manifest in how the regulators around the globe approach anything from
knives to pepper spray – but of course, no topic is more contentious than firearms. The debate about
the social benefits and costs of gun ownership is
hopelessly
polarizing and clouded by emotion; I’m certain that roughly half of the folks reading this document
have a very visceral, negative reaction to the very idea that a private person should be allowed
to carry a gun – and I do not honestly expect to change their minds.

That said, when we look beyond the dogma, the underlying facts paint
an
incredibly nuanced picture of the right to bear arms – putting into question many of the deeply-held and seemingly
common-sense beliefs. For example, despite the striking ubiquity of legally owned
firearms in the United States – about one per every resident – the country historically enjoyed
lower per-capita rates of suicide, robbery, assault, or rape, compared to some of its esteemed European
peers.

Of course, this observation ignores one important fact: compared to EU countries, the US
suffers from a markedly elevated (but rapidly falling) rate of homicide. About two thirds of homicides are committed with
guns – but lest we jump to conclusions, the non-firearm-related murder rate alone puts America well
ahead of most of Europe, suggesting that the cause may have to do with societal differences as much
as with the availability of a particular tool. A finding that supports this theory is the fact that upward of 80%
of US gun homicides
trace back to gang activity and drug trade,
often within the disadvantaged or impoverished strata of the society.
Another telling observation is that comparisons of overall murder rates across US states or across EU countries
with vastly different firearms ownership profiles
don’t reveal a convincing
correlation between the two variables – something you would expect to see if legally owned
guns had a causative relationship with violent crime.

Of course, these points can be debated, and there’s ample evidence to cherry-pick in support of any view.
But there is also a more utilitarian way of looking at it. From an individualistic, survival-focused
point of view, the social costs (real or imagined) are essentially moot: if you live in a place where guns
are readily available to criminals, it’s hard to think of a violent confrontation where not owning a
firearm would give you the upper hand. While the data is a bit dicey, there is a body of research showing that
defensive gun uses happen in the US at a rate of somewhere
south of 500,000 times a year,
with almost all confrontations resolved without firing a single shot. The inherent dangers of owning
a firearm are often overstated by gun control advocates, too: unintentional injury or death due to
having a gun at home is
comparatively rare, and is almost
always a consequence of blatant disregard for basic safety rules.

All in all, it’s OK to reject armed self-defense (or shun guns in particular) on religious or moral
grounds – but doing so is probably not a particularly rational decision within the scope of this
guide. From a rational standpoint, you should always pick the tools that are best suited for the scenarios
you anticipate (provided that the state allows you to). Of course, a firearm is not always the
answer, so let’s take a broader look at some of the most popular options for shooing away looters or
defending yourself:

• Bare hands.

  No deterrent effect, but surprisingly effective when a confrontation can’t be avoided –
  especially when facing a single assailant.
  Reserved for people who are physically fit and willing to invest a fair amount of time into training. One of the most pragmatic
  and widely-taught schools is Krav Maga, and there’s certainly no harm in checking it out.

• Pepper spray.

  An excellent, temporarily incapacitating weapon – very difficult to resist and capable of buying you just
  enough time to escape. Works quickly and reliably at distances up to perhaps 10 feet; can also stop some animal
  attacks. Usually not heavily regulated, making it easy to obtain and carry even in places
  that frown upon other forms of armed self-defense (but check the laws). Pepper spray becomes less effective in
  strong wind; there is also some risk of blowback, but this is mitigated in narrow-stream products,
  such as Sabre Pepper Gel.

• Knives.

  Very lethal and dangerous at close quarters, but only provided that you have the element of
  surprise on your side. They require some degree of physical fitness and training to use well.
  Their value is diminished when facing multiple assailants or dealing with a gun-wielding
  individual: even if you stab them, you are probably still gonna get shot. In a handful of places,
  carrying a knife may be illegal or subject to somewhat confusing
  restrictions, so perform due diligence if you want to take this route.

• Stun guns.

  A nice idea, in theory. Unfortunately, most products require direct body contact with the attacker,
  are easily foiled by clothing, and may be less effective against people who are well-built,
  unusually agitated, or just high on drugs. While it’s a popular self-defense choice, I can’t honestly
  recommend it over pepper spray.

  (Projectile-type stun guns, such as Taser C2, are far better and work at a distance – but
  you need to have perfect aim on first try. They also cost quite a bit.)

• Firearms.

  A very effective and supremely intimidating weapon, with lethality ranging from
  20% for handguns to 80% for shotguns; for a novice user, the effective range is somewhere
  between 10 and 100 yards. Guns are heavily regulated in much of the world, but widely
  available in the US – although there are several states or municipalities that make it
  very difficult to get a permit unless you are
  a celebrity
  or a prominent donor.

  Even if your local government does not issue carry permits or erects other bureaucratic roadblocks,
  having a firearm in your home can provide
  a very effective deterrent in case of home intrusions. That said, a gun is also a responsibility:
  similarly to a chainsaw, you are either serious about following the safety rules, or somebody may get
  hurt.

Interestingly, the legal bar for claiming self-defense is typically no different whether you are
using a less-lethal weapon or lethal force. But of course, the legal and psychological consequences of
being wrong can be far more severe if you kill a person, versus just making their eyes itch. There are
no easy answers, so do some soul-searching first. If you can’t imagine killing another person to protect
your family – and living with the consequences – don’t get a knife or a gun.

4.8.4. Defense topic #4: Understanding firearms https://lcamtuf.coredump.cx/prep/index-old.shtml

If you are contemplating getting a gun for home defense or for more outlandish survival scenarios,
the first choice you will face is between a handgun, a shotgun, and a rifle. Here’s what you need to know:

• Handguns.

  This category encompasses a wide selection of small, lower-powered firearms that can be easily carried
  without attracting attention. Most have a fairly modest stopping power, so-so ballistics,
  and require quite a bit of
  practice to accurately hit anything more than 10 yards away. A telling statistic is that in shootouts,
  the police have a hit rate of less than 30%; contrary to what some gun control supporters
  claim, an average policeman does not get that much practice, and probably trains less than your typical
  gun enthusiast – but these numbers are still something to keep in mind.

  Handguns are typically regulated more heavily than other firearms, in part because they account for
  the overwhelming majority of all gun crime. If you can get one, your basic choice is between:

  • Semi-automatic pistols. Typically capable of firing
    somewhere around 6 to 18 rounds from a removable magazine; reloading is very fast, provided that you carry
    another magazine with you. Their user interface is relatively complex, and some knowledge is needed
    to deal with potential misfires, jams, or to avoid negligent discharges – although the probability of
    any such issues is generally very low. (It’s wise to avoid bargain-bin ammo and magazines.)

  • Revolvers. A more ancient type of a repeating firearm, usually holding 5 or 6 rounds in
    a non-removable cylinder. They are functionally simple, very dependable, and pretty accurate – but
    take more time to reload if it ever comes to that.

  You may be tempted to go for the most lightweight and highest-powered handgun you can find, but you
  would have to cope with punishing recoil and potentially blinding muzzle flash, so it’s not always a
  good call. In home defense situations, mid- to full-size 9mm pistols and .38 Special revolvers are probably
  the sweet spot. There are countless models to choose from, but the bottom line is that you can’t go particularly
  wrong with Glock, Beretta, SIG Sauer, Ruger, Smith & Wesson, CZ, Heckler & Koch, or Springfield Armory.

  If you need some starting points for your search, perhaps the most iconic and time-tested semi-auto design is the 1911; it
  was originally a pretty bulky and heavy all-steel firearm, but many manufacturers now make
  lighter, scaled-down variants that are OK for
  carrying around. More modern, higher-capacity successors include pistols such as
  SIG P226 or CZ 75B; as well as a growing number of compact, polymer-frame guns, including
  Glock 43, M&P Shield, or SIG P365.

  For revolvers, Ruger SP101 and Smith & Wesson 642 are probably two very reasonable
  picks to haul around. Some very futuristic if a tad more expensive
  revolvers are made by Chiappa, too; Rhino 30DS and 40DS are two nice picks.

• Rifles.

  Long, heavy guns, often with detachable magazines housing anywhere from 4 to 30 rounds. Rifles
  fire high-velocity projectiles capable of accurately striking distant targets – and even a complete novice
  should be able to hit targets 30-50 yards away. With plenty of practice (and expensive optics), some
  rifles allow reliable hits at 1,000 yards or so.

  The most popular category are semi-automatic rifles, including the scary-looking
  AR-15 clones,
  the much less villainous Ruger Mini-14, and
  a bunch of in-between choices, such as
  Fightlite SCR.
  All three are known for reliability and good accuracy. Semi-automatics typically
  fire relatively small but high-energy projectiles (e.g., .223 Remington / 5.56x45mm NATO); although considerably
  louder than most handgun calibers, such projectiles are still somewhat suitable for home defense and
  hunting small to medium game.

  Another popular pick are bolt-action rifles, including Remington 700, Winchester 70, Ruger Hawkeye,
  and Ruger Precision Rifle.
  Although there is a lot of variety, many are chambered for larger cartridges ideal for hunting big game
  (from .243 Winchester to .50 BMG) and are more suited for long-range shooting. For home defense,
  overpenetration becomes a significant concern.

  In the US, long guns are subject to fewer restrictions than handguns, chiefly because of their negligible
  role in street crime; that said, “assault weapons” – i.e., semi-automatic rifles with scary-looking cosmetic
  features, such as barrel shrouds or forward grips – have been a subject of recurring moral panics
  and various state- or municipality-level restrictions and bans.

  Perhaps interestingly, there is a handful of rifles chambered for handgun ammunition. The classics
  include Ruger 77 series, Henry Big Boy, and the replicas of
  Winchester Models 1873 and 1892 (e.g., Chiappa 1892 Alaskan);
  some of the more modern semi-automatic options include Ruger PC and KelTec SUB2000.
  In the prepper context, their appeal is that you only need to
  keep one kind of ammo for two types of firearms. Putting a handgun caliber in a rifle gives you greatly
  improved accuracy, virtually no recoil, comparatively quiet operation, and somewhat improved range – but going past
  100 yards is still going to be a stretch.

• Shotguns.

  Long, heavy, large-bore weapons with tremendous stopping power, variously firing one large metal
  slug or a swarm of high-energy pellets; less-lethal rubber batons are also sometimes used for
  crowd or animal control. Aimed as easily as rifles, but because of the less ergonomic shapes of
  projectiles and their lower velocities, the effective range of a shotgun doesn’t extend far
  beyond 100-200 yards. In places such as Australia or the UK, buying a shotgun is subject to
  fewer restrictions than other types of firearms.

  Excellent for home defense, where they combine high stopping power and accuracy with reduced
  risk of overpenetration (depending on the ammo used). Also popular for waterfowl hunting (where multiple projectiles reduce
  the need for very precise aim), deer hunting, and for encounters with
  predators such as mountain lions, bears, and the like.

  Most shotguns pack a substantial amount of recoil and can easily bruise your shoulder –
  although lower-powered loads or smaller-gauge
  variants (e.g., 20 ga) can be operated by small-framed or younger shooters.
  Capacity typically ranges from 2 to 8 shells. A very affordable, popular, and reliable
  type of a shotgun is pump-action (reloaded by racking the slide); two of the best-known
  examples are
  Remington 870 and Mossberg 590.

When it comes to self-defense, hollow point ammunition (HP / JHP) is preferred for rifles and handguns;
compared to solid metal bullets, it deforms and falls apart more readily on impact – therefore
reducing the risk of overpenetration and collateral damage.

If you decide to get a gun, you must learn how to operate it safely: sign up for a basic course
or have someone truly competent take you to the range. The basic safety rules can be summed up as:

• Rule #1: When picking up a gun, always assume that it’s loaded. Don’t trust others and
  definitely don’t trust your own memory. Always double-check. If you don’t know how to operate
  a particular gun, ask before touching it. In firearms with removable magazines, always check the
  chamber after removing the mag.

• Rule #2: Assume that you will eventually mess up rule #1, so when handling a gun, always keep it
  pointed in a safe direction. “Sweeping” other people is a no-no, so is looking down the barrel.
  At the shooting range, the safe direction is down range, toward the backstop.
  At home, just be mindful of neighbors and people in other rooms.

• Rule #3: Assume that you will eventually break rules #1 and #2, so keep your finger off the
  trigger unless the gun is aimed and you’re ready to fire.

• Rule #4: When firing, know your target and what’s beyond it. You don’t want to shoot
  a drunk family member in the middle of the night, or have a bullet go through your target and strike
  a bystander.

With the rules internalized, you are extremely unlikely to cause unintentional harm.
Keep practicing at least twice a month until you get good, and then go to the range at
least several times a year. Try to use
practice ammo with lead-free primers and clean bullets (e.g., RUAG Copper Matrix,
Magtech Clean Range, Winchester Super Clean, Winchester Frangible, Federal Ballisticlean,
Remington Disintegrator, Federal American Eagle TMJ, Federal Power-Shok Copper) and avoid
tracking lead residues from indoor ranges back home –
especially if you have small kids. Always wear hearing and eye protection, too.

Keep your firearms in a quick-access safe if you have young children or expect people with kids
to visit you every now and then. A safe is also a good way to deter opportunistic theft; a clever
hiding place will also do, but criminals often have the same ideas as you and know where to look.
Be smart about picking the right safe and placing it sensibly: you don’t want to have to walk to the
other end of the house, or to fiddle with keys or rotary dials, when every second counts.
Electronic combination or biometric safes are usually pretty good, unless you go for the bargain bin
(don’t).

5. Organizing and tracking your supplies https://lcamtuf.coredump.cx/prep/index-old.shtml

Robust bookkeeping is an essential component of any preparedness plan. Without a neat
spreadsheet to go back to, you will eventually lose track of the stuff you have, won’t be able to locate
critical supplies in a pinch, and won’t know if and when your batteries, food, or meds have
gone bad.

To get it right, make a list of all your emergency gear, along with expiration dates where applicable.
Next, go through the list marking all the “stays home” stuff – the supplies that are impractical
to haul around or not particularly essential when evacuating. Make sure that all the tactical gear
– such as flashlights, fire extinguishers, first-aid kits, and self-defense weapons – are in a
logical and easily reached place. For the remaining “stay home” items,
just find an unobtrusive location, stow them away, and write the spot down in your spreadsheet.

The task of organizing the essentials you want to travel with is a bit
more involved. For car owners, I suggest preparing two separate kits:

• Boxed evacuation essentials.

  Camping and survival supplies to get you through at least one week, in case you need to leave home
  and can’t be sure about finding a hospitable location right away. The gear should be boxed
  or bagged to make it easy to load into your vehicle. Include some amount of water and food,
  and make sure that the entire kit actually fits into the car. For many US cars,
  56 quart storage totes work very well.

• A get-me-home box.

  A container always kept in the trunk, small enough so that it doesn’t hinder your normal
  use of the car, but substantial enough to help you survive several days (or cope with other,
  more prosaic roadside emergencies). The kit should include 1-2 gallons of water, Mylar
  blankets, rope, and other car supplies discussed earlier in the guide. A
  collapsible water bottle and a folding daypack can be useful if you have
  to walk on foot from a broken car to the nearest town. Throwing in
  some cash – just enough to pay for gas, a meal, a motel room, or a ride home – is also a
  good plan.

While you’re at it, also check that you have a spare tire, a jack, a lug wrench, and a box of extra
fuses. They come optional on some very cheap cars, and may be simply missing when you buy a used one.
Some people find out too late.

Folks without a car are at a marked disadvantage, but should still try to put together
a 72-hour “bug out bag” – and ideally, keep it somewhere within a walking or biking
distance of their home (say, at work or at a friend’s place). It’s best to keep it light;
some cash, 2-4 quarts of water, a 3,600 kcal emergency ration, and a raincoat will be almost
certainly more useful than a gun and a collection of throwing knives.

Either way, when done with the list, be sure to re-read the response plans you drafted earlier on
and cross-reference them with this spreadsheet. Iterate until you’re happy with both, then
print out the docs and place them somewhere intuitive. In a stressful situation, you will
be able to quickly review the printouts to confirm that you are not missing anything.

6. Final words https://lcamtuf.coredump.cx/prep/index-old.shtml

Here is a closing thought:
rational prepping is meant to give you confidence to go about your business, knowing that you are
well-equipped to weather out adversities. It should not be about convincing yourself that the
collapse is just around the corner, and letting that thought consume and disrupt your life.

I’d stay positive: the world is probably not ending,
and there is a good chance that it will be
an even better place for our children than it is for us. But the universe is a harsh mistress, and
there is only so much faith we should be putting in good fortune, in benevolent governments, or in
the wonders of modern technology. So, always have a backup plan.
