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. In high rise buildings, go to interior small rooms or halls. Stay away from exterior walls or glassy areas.
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. Lightning can strike up to several miles away from the thunderstorm. Do not take a bath or shower. A pickup truck or hard top automobile with the windows up can also offer fair protection.
