person in the shelter. Sanitation also may have to be managed and
controlled, perhaps by setting up emergency toilets and rules to insure
that they are used properly.

If you go to a _public_ fallout shelter in a time of attack, you
probably would not need to know a great deal about managing water, food,
and sanitation. A shelter manager and his assistants would handle these
problems with the cooperation of all in the shelter. He would make the
best use of whatever water and food supplies were available, provide
emergency toilets if necessary, set up rules for living in the shelter,
arrange for the shelter occupants to carry on various activities
necessary for health and well-being, and decide when it was safe for the
group to leave shelter and for how long at a time.

In a _home_ fallout shelter, however, you and your family would be
largely on your own. You would have to take care of yourselves, solve
your own problems, make your own living arrangements, subsist on the
supplies you had previously stocked, and find out for yourself (probably
by listening to the radio) when it was safe to leave shelter. In this
situation, one of your most important tasks would be to manage your
water and food supplies, and maintain sanitation. The following guidance
is intended to help you do this.

CARE AND USE OF WATER SUPPLIES

The average person in a shelter would need at least 1 quart of water or
other liquids per day to drink, but more would be useful (to allow some
for washing, etc.). Therefore a rationing plan might be required in your
home shelter, so as to make your available liquids last for 14 days.
(Many communities may continue to have potable water available, and
families could relax their rationing plans.)

In addition to water stored in containers, there is usually other water
available in most homes that is drinkable, such as:

--Water and other liquids normally found in the kitchen, including ice
cubes, milk, soft drinks, and fruit and vegetable juices.

--Water (20 to 60 gallons) in the hot water tank.

--Water in the _flush tanks_ (not the bowls) of home toilets.

--Water in the pipes of your home plumbing system. In a time of nuclear
attack, local authorities may instruct householders to _turn off_ the
main water valves in their homes to avoid having water drain away in
case of a break and loss of pressure in the water mains. With the main
valve in your house closed, all the pipes in the house woul
