The units can be used as book cases, pantry shelves, or for miscellaneous storage. In an emergency, the storage units can be tilted up so that they rest on a stacked masonry wall built from materials stored nearby the units. In basements where the outside ground level is above the top of the tilted- up units, adequate shelter from fallout radiation is provided by filling the units with brick or solid concrete block 8” thick. The shelter will house 6 people. Approximately 2 man days are required to construct the storage units. The materials are readily available, from retail lumber yards.
