Tornados
If a tornado was approaching, would you know what to do?
Tornadoes are the most violent atmospheric phenomenon on
the planet. Winds of 200-300 mph can occur with the most violent tornadoes. The
following are instructions on what to do when a tornado warning has been issued
for your area or whenever a tornado threatens:
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. 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. See the left figure for an example of where to go in a school. Crouch
down and cover your head as shown in the right figure.
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.
The picture below illustrates clearly what a violent tornado can do to a car.
IF NO SUITABLE STRUCTURE IS NEARBY:
Lie flat in the nearest ditch or depression and use your
hands to cover your head.
