In Homes Or Small Buildings:
Go to the basement (if available) or to an interior room on the lowest floor, such as a closet or bathroom. Upper floors are unsafe. If there is no time to descend, go to a closet, a small room with strong walls, or an inside hallway. Wrap yourself in overcoats or blankets to protect yourself from flying debris.
In Schools, Hospitals, Factories Or Shopping Centers:
Go to interior rooms and halls on the lowest floor. Stay away from glass enclosed places or areas with wide-span roofs such as auditoriums and warehouses. Crouch down and cover your head. Don't take shelter in halls that open to the south or the west. Centrally-located stairwells are good shelter.
In High-Rise Buildings:
Go to interior small rooms or halls. Stay away from exterior walls or glassy areas.
In Cars Or Mobile Homes:
ABANDON THEM IMMEDIATELY!!! Most deaths occur in cars and mobile homes. If you are in either of those locations, leave them and go to a substantial structure or designated tornado shelter.
If no Suitable Structure Is Nearby:
Lie flat in the nearest ditch or depression and use your hands to cover your head. Be alert for flash floods.
During A Tornado:
Absolutely avoid buildings with large free-span roofs. Stay away from west and south walls. Remember: lowest level, smallest room, center part.
To Prepare For A Tornado:
Store water in clean covered containers. You should keep disaster supplies in your home at all times (i.e. flashlight, candles, matches, etc.).
