Natural ventilation is provided by the shelter entrance, and by the air
vents shown in the shelter wall.

This shelter can be used as a storage room or for other useful purposes
in non-emergency periods.


A PREPLANNED BASEMENT SHELTER. If your home has a basement but you do
not wish to set up a permanent-type basement shelter, the next best
thing would be to arrange to assemble a "preplanned" home shelter. This
simply means gathering together, in advance, the shielding material you
would need to make your basement (or one part of it) resistant to
fallout radiation. This material could be stored in or around your home,
ready for use whenever you decided to set up your basement shelter.

Here are two kinds of preplanned basement shelters. If you want to set
up one of these, be sure to _get the free plan for it first_ by writing
to Civil Defense, Army Publications Center, 2800 Eastern Blvd. (Middle
River), Baltimore, Md. 21220. Mention the full name of the plan you
want.


PREPLANNED SNACK BAR SHELTER PLAN D

This is a snack bar built of bricks or concrete blocks, set in mortar,
in the "best" corner of your basement (the corner that is most below
ground level). It can be converted quickly into a fallout shelter by
lowering a strong, hinged "false ceiling" so that it rests on the snack
bar.
