Emergency Food and Water Supplies
If an earthquake, hurricane, winter storm or other disaster ever strikes
your community, you might not have access to food, water and electricity
for days, or even weeks. By taking a little time now to store emergency
food and water supplies, you can provide for your entire family.
This brochure was developed by the Federal Emergency Management Agency's
Community and Family Preparedness Programs which provides information to
help families prepare for all types of disasters.
WATER: THE ABSOLUTE NECESSITY
Stocking water reserves and learning how to purify contaminated water
should be among your top priorities in preparing for an emergency. You should
store at least a two-week supply of water for each member of your family.
Everyone's needs will differ, depending upon age, physical condition, activity,
diet and climate. A normally active person needs to drink at least two quarts
of water each day. Hot environments can double that amount. Children, nursing
mothers and ill people will need more. You will need additional water for
food preparation and hygiene. Store a total of at least one gallon per person,
If your supplies begin to run low, remember: Never ration water. Drink
the amount you need today, and try to find more for tomorrow. You can minimize
the amount of water your body needs by reducing activity and staying cool.
How to Store Emergency Water Supplies
You can store your water in thoroughly washed plastic, glass, fiberglass
or enamel-lined metal containers. Never use a container that has held toxic
substances, because tiny amounts may remain in the container's pores. Sound
plastic containers, such as soft drink bottles, are best. You can also purchase
food-grade plastic buckets or drums.
Before storing your water, treat it with a preservative, such as chlorine
bleach, to prevent the growth of microorganisms. Use liquid bleach that
contains 5.25 percent sodium hypochlorite and no soap. Some containers warn,
"Not For Personal Use." You can disregard these warnings if the
label states sodium hypochlorite is the only active ingredient and if you
use only the small quantities in these instructions.
Add four drops of bleach per quart of water (or two scant teaspoons per
10 gallons), and stir. Seal your water containers tightly, label them and
store them in a cool, dark place.
Hidden Water Sources in Your Home
If a disaster catches you without a stored supply of clean water, you
can use water in your hot-water tank, in your plumbing and in ice cubes.
As a last resort, you can use water in the reservoir tank of your toilet
(not the bowl), but purify it first (described later).
Water beds hold up to 400 gallons, but some water beds contain toxic
chemicals that are not fully removed by many purifiers. If you designate
a water bed in your home as an emergency resource, drain it yearly and refill
it with fresh water containing two ounces of bleach per 120 gallons.
To use the water in your pipes, let air into the plumbing by turning
on the highest faucet in your house and draining the water from the lowest
To use the water in your hot-water tank, be sure the electricity or gas
is off, and open the drain at the bottom of the tank. Start the water flowing
by turning off the water intake valve and turning on a hot-water faucet.
Do not turn on the gas or electricity when the tank is empty.
Do you know the location of your incoming water valve? You'll need to
shut if off to stop contaminated water from entering your home if you hear
reports of broken water or sewage lines.
Emergency Outdoor Water Sources
If you need to seek water outside your home, you can use these sources.
But purify the water before drinking it.
- Streams, rivers and other moving bodies of water
- Ponds and lakes
- Natural springs
Avoid water with floating material, an odor or dark color. Use saltwater
only if you distill it first (described later).
Three Easy Ways to Purify Water
In addition to having a bad odor and taste, contaminated water can contain
microorganisms that cause diseases such as dysentery, cholera, typhoid and
hepatitis. You should therefore purify all water of uncertain purity before
using it for drinking, food preparation or hygiene.
There are many ways to purify water. None are perfect. Often the best
solution is a combination of methods. Before purifying, let any suspended
particles settle to the bottom, or strain them through layers of paper towel
or clean cloth.
Three easy purification methods are outlined below. These measures will
kill microbes but will not remove other contaminants such as heavy metals,
salts, most other chemicals and radioactive fallout.
Boiling is the safest method of purifying water. Bring water to a rolling
boil for 10 minutes, keeping in mind that some water will evaporate. Let
the water cool before drinking.
Boiled water will taste better if you put oxygen back into it by pouring
it back and forth between two containers. This will also improve the taste
of stored water.
Chlorination uses liquid chlorine bleach to kill microorganisms. (See
page 1 for bleach safety information.) Add two drops of bleach per quart
of water (four drops if the water is cloudy), stir and let stand for 30
minutes. If the water does not taste and smell of chlorine at that point,
add another dose and let stand another 15 minutes.
If you do not have a dropper, use a spoon and a square-ended strip of
paper or thin cloth about 1/4 inch by 2 inches. Put the strip in the spoon
with an end hanging down about 1/2 inch below the scoop of the spoon. Place
bleach in the spoon and carefully tip it. Drops the size of those from a
medicine dropper will drip off the end of the strip.
Purification tablets release chlorine or iodine. They are inexpensive
and available at most sporting goods stores and some drugstores. Follow
the package directions. Usually one tablet is enough for one quart of water.
Double the dose for cloudy water.
More Rigorous Purification Methods
While the three methods described above will remove only microbes from
water, the following two purification methods will remove other contaminants.
Distillation will remove microbes, heavy metals, salts, most other chemicals,
and radioactive dust and dirt, called radioactive fallout. Filtering will
also remove radioactive fallout. (Water itself cannot become radioactive,
but it can be contaminated by radioactive fallout. It is unsafe to drink
water that contains radioactive fallout.)
Distillation involves boiling water and then collecting the vapor that
condenses back to water. The condensed vapor will not include salt and other
impurities. To distill, fill a pot halfway with water. Tie a cup to the
handle on the pot's lid so that the cup will hang right-side-up when the
lid is upside-down (make sure the cup is not dangling into the water) and
boil the water for 20 minutes. The water that drips from the lid into the
cup is distilled.
To make a fallout filter, punch holes in the bottom of a large bucket,
and put a layer of gravel in the bucket about 1-1/2 inches high. Cover the
gravel with a towel cut in a circle slightly larger than the bucket. Cover
soil with a towel, place the filter over a large container, and pour contaminated
water through. Then, disinfect the filtered water using one of the methods
described above. Change the soil in your filter after every 50 quarts of
Family Disaster Supply Kit
It's 2:00 a.m. and a flash flood forces you to evacuate your home--fast.
There's no time to gather food from the kitchen, fill bottles with water,
grab a first-aid kit from the closet and snatch a flashlight and a portable
radio from the bedroom. You need to have these items packed and ready in
one place before disaster hits.
Pack at least a three-day supply of food and water, and store it in a
handy place. Choose foods that are easy to carry, nutritious and ready-to-eat.
In addition, pack these emergency items:
- Medical supplies and first aid manual
- Hygiene supplies
- Portable radio, flashlights and extra batteries
- Shovel and other useful tools
- Money and matches in a waterproof container
- Fire extinguisher
- Blanket and extra clothing
- Infant and small children's needs (if appropriate)
FOOD: PREPARING AN EMERGENCY STOCKPILE
If activity is reduced, healthy people can survive on half their usual
food intake for an extended period and without any food for many days. Food,
unlike water, may be rationed safely, except for children and pregnant women.
If your water supply is limited, try to avoid foods that are high in
fat and protein, and don't stock salty foods, since they will make you thirsty.
Try to eat salt-free crackers, whole grain cereals and canned foods with
high liquid content.
You don't need to go out and buy unfamiliar foods to prepare an emergency
food supply. You can use the canned foods, dry mixes and other staples on
your cupboard shelves. In fact, familiar foods are important. They can lift
morale and give a feeling of security in time of stress. Also, canned foods
won't require cooking, water or special preparation. Following are recommended
short-term and long-term food storage plans.
- Keep food in the driest and coolest spot in the house--a dark area
- Keep food covered at all times.
- Open food boxes or cans carefully so that you can close them tightly
after each use.
- Wrap cookies and crackers in plastic bags, and keep them in tight containers.
- Empty opened packages of sugar, dried fruits and nuts into screw-top
jars or air-tight cans to protect them from pests.
- Inspect all food containers for signs of spoilage before use.
Short-Term Food Supplies
Even though it is unlikely that an emergency would cut off your food
supply for two weeks, you should prepare a supply that will last that long.
A two-week supply can relieve a great deal of inconvenience and uncertainty
until services are restored.
The easiest way to develop a two-week stockpile is to increase the amount
of basic foods you normally keep on your shelves. Remember to compensate
for the amount you eat from other sources (such as restaurants) during an
average two-week period.
You may already have a two-week supply of food on hand. Keeping it fresh
is simple. Just rotate your supply once or twice a year.
Special Considerations to Keep in Mind
As you stock food, take into account your family's unique needs and tastes.
Try to include foods that they will enjoy and that are also high in calories
and nutrition. Foods that require no refrigeration, preparation or cooking
Individuals with special diets and allergies will need particular attention,
as will babies, toddlers and the elderly. Nursing mothers may need liquid
formula, in case they are unable to nurse. Canned dietetic foods, juices
and soups may be helpful for the ill or elderly.
Make sure you have a can opener and disposable utensils. And don't forget
nonperishable foods for your pets.
How to Store Your Short-Term Stockpile
Keep canned foods in a dry place where the temperature is fairly cool--not
above 70 degrees Fahrenheit and not below freezing. To protect boxed foods
from pests and extend their shelf life, store the boxes in tightly closed
cans or metal containers.
Rotate your food supply. Use foods before they go bad, and replace them
with fresh supplies, dated with ink or marker. Place new items at the back
of the storage area and older ones in front.
Your emergency food supply should be of the highest quality possible.
Inspect your reserves periodically to make sure there are no broken seals
or dented containers.
How to Cook if the Power Goes Out
For emergency cooking you can use a fireplace, or a charcoal grill or
camp stove outdoors only. You can also heat food with candle warmers, chafing
dishes and fondue pots. Canned food can be eaten right out of the can. If
you heat it in the can, be sure to open the can and remove the label first.
Long-Term Food Supplies
In the unlikely event of a military attack or some other national disaster,
you may need long-term emergency food supplies. The best approach is to
store large amounts of staples along with a variety of canned and dried
foods. Bulk quantities of wheat, corn, beans and salt are inexpensive and
have nearly unlimited shelf life. If necessary, you could survive for years
on small daily amounts of these staples. Stock the following amounts per
person, per month: Wheat--20 pounds
Powdered Milk(for babies and infants)*-- 20 pounds
Iodized Salt--1 pound
Vitamin C**--15 grams
* Buy in nitrogen-packed cans
** Rotate every two years
Storage and Preparation of Food Supplies
Store wheat, corn and beans in sealed cans or plastic buckets. Buy powdered
milk in nitrogen-packed cans. And leave salt and vitamin C in their original
If these staples comprise your entire menu, you must eat all of them
together to stay healthy. To avoid serious digestive problems, you'll need
to grind the corn and wheat into flour and cook them, as well as boil the
beans, before eating. Many health food stores sell hand-cranked grain mills
or can tell you where you can get one. Make sure you buy one that can grind
corn. If you are caught without a mill, you can grind your grain by filling
a large can with whole grain one inch deep, holding the can on the ground
between your feet and pounding the grain with a pipe.
In a crisis, it will be vital that you maintain your strength. So remember:
- Eat at least one well-balanced meal each day.
- Drink enough liquid to enable your body to function properly (two quarts
- Take in enough calories to enable you to do any necessary work.
- Include vitamin, mineral and protein supplements in your stockpile
to assure adequate nutrition.
Shelf Life of Foods for Storage
Here are some general guidelines for rotating common emergency foods.
- Use within six months:
- Powdered milk (boxed)
- Dried fruit (in metal container)
- Dry, crisp crackers (in metal container)
- Use within one year:
- Canned condensed meat and vegetable soups
- Canned fruits, fruit juices and vegetables
- Ready-to-eat cereals and uncooked instant cereals (in metal containers)
- Peanut butter
- Hard candy, chocolate bars and canned nuts
- May be stored indefinitely (in proper containers and conditions):
- Vegetable oils
- Baking powder
- Instant coffee, tea
- Vitamin C
- and cocoa
- Noncarbonated soft drinks
- White rice
- Bouillon products
- Dry pasta
- Powdered milk (in nitrogen-packed cans)
Ways to Supplement Your Long-Term Stockpile
The above staples offer a limited menu, but you can supplement them with
commercially packed air-dried or freeze-dried foods and supermarket goods.
Rice, popcorn and varieties of beans are nutritious and long-lasting. The
more supplements you include, the more expensive your stockpile will be.
Following is an easy approach to long-term food storage:
- Buy a supply of the bulk staples listed above.
- Build up your everyday stock of canned goods until you have a two-week
to one-month surplus. Rotate it periodically to maintain a supply of common
foods that will not require special preparation, water or cooking.
- From a sporting or camping equipment store, buy commercially packaged,
freeze-dried or air-dried foods. Although costly, this will be your best
form of stored meat, so buy accordingly.
If the Electricity Goes Off... FIRST, use perishable food
and foods from the refrigerator.
THEN use the foods from the freezer. To minimize the number of times
you open the freezer door, post a list of freezer contents on it. In a well-filled,
well-insulated freezer, foods will usually still have ice crystals in their
centers (meaning foods are safe to eat) for at least three days.
FINALLY, begin to use non-perishable foods and staples.
