Find out from officials if any public buildings in your community have been designated as fallout shelters.
If none have been designated, make your own list of potential shelters near your home, workplace, and school. These places would include basements or the windowless center area of middle floors in high-rise buildings as well as subways and tunnels.
If you live in an apartment building or high-rise, talk to the manager about the safest place in the building for sheltering and providing for building occupants until it is safe to go out.
During periods of increased threat, make sure your disaster supplies will be adequate for up to two weeks.
Blast & Fallout Shelters
Blast shelters are specifically constructed to offer some protection against blast pressure, initial radiation, heat, and fire. Even a blast shelter, however, can not withstand a direct hit from a nuclear explosion.
Fallout shelters do not need to be specially constructed for protecting against fallout. They can be any protected space if the walls and roof are thick and dense enough to absorb the radiation given off by fallout particles.
