Preparing for
Tornadoes
When a tornado
is coming, you have only a short amount of time to make life-or-death
decisions. Advance planning and quick response are the keys to surviving
a tornado.
BEFORE
Conduct tornado
drills each tornado season.
Designate an area in the home as a shelter, and practice having
everyone in the family go there in response to a tornado threat.
Discuss with
family members the difference between a "tornado watch" and a "tornado
warning."
Contact your
local emergency management office or American Red Cross chapter
for more information on tornadoes.
Have disaster
supplies on hand.
- Flashlight
and extra batteries
- Portable,
battery-operated radio and extra batteries
- First aid
kit and manual
- Emergency
food and water
- Nonelectric
can opener
- Essential
medicines
- Cash and
credit cards
- Sturdy shoes
Develop an emergency
communication plan.
In case family
members are separated from one another during a tornado (a real
possibility during the day when adults are at work and children
are at school), have a plan for getting back together.
Ask an out-of-state
relative or friend to serve as the "family contact." After a disaster,
it's often easier to call long distance. Make sure everyone in the
family knows the name, address, and phone number of the contact
person.
Tornado Watches
and Warnings
A tornado
watch is issued by the National Weather Service when tornadoes
are possible in your area. Remain alert for approaching storms.
This is time to remind family members where the safest places within
your home are located, and listen to the radio or television for
further developments.
A tornado
warning is issued when a tornado has been sighted or indicated
by weather radar.
Mobile Homes
Mobile homes
are particularly vulnerable. A mobile home can overturn very easily
even if precautions have been taken to tie down the unit. When a
tornado warning is issued, take shelter in a building with a strong
foundation.If shelter is not available, lie in ditch or low-lying
area a safe distance away from the unit.
Tornado Danger
Signs
Learn these
tornado danger signs:
- An approaching
cloud of debris can mark the location of a tornado even if a funnel
is not visible.
- Before a
tornado hits, the wind may die down and the air may become very
still.
- Tornadoes
generally occur near the trailing edge of a thunderstorm. It is
not uncommon to see clear, sunlit skies behind a tornado.
DURING
If at home:
- Go at once
to the basement, storm cellar, or the lowest level of the building.
- If there
is no basement, go to an inner hallway or a smaller inner room
without windows, such as a bathroom or closet.
- Get away
from the windows.
- Go to the
center of the room. Stay away from corners because they tend to
attract debris.
- Get under
a piece of sturdy furniture such as a workbench or heavy table
or desk and hold on to it.
- Use arms
to protect head and neck.
- If in a mobile
home, get out and find shelter elsewhere.
If at work or
school:
- Go to the
basement or to an inside hallway at the lowest level.
- Avoid places
with wide-span roofs such as auditoriums, cafeterias, large hallways,
or shopping malls.
- Get under
a piece of sturdy furniture such as a workbench or heavy table
or desk and hold on to it.
- Use arms
to protect head and neck.
If outdoors:
- If possible,
get inside a building.
- If shelter
is not available or there is no time to get indoors, lie in a
ditch or low-lying area or crouch near a strong building. Be aware
of the potential for flooding.
- Use arms
to protect head and neck.
If in a car:
- Never try
to outdrive a tornado in a car or truck. Tornadoes can change
direction quickly and can lift up a car or truck and toss it through
the air.
- Get out of
the car immediately and take shelter in a nearby building.
- If there
is no time to get indoors, get out of the car and lie in a ditch
or low-lying area away from the vehicle. Be aware of the potential
for flooding.
AFTER
Help injured
or trapped persons
. Give first
aid when appropriate. Don't try to move the seriously injured unless
they are in immediate danger of further injury. Call for help.
- Turn on radio
or television to get the latest emergency information.
- Stay out
of damaged buildings. Return home only when authorities say it
is safe.
- Use the telephone
only for emergency calls.
- Clean up
spilled medicines, bleaches, or gasoline or other flammable liquids
immediately. Leave the buildings if you smell gas or chemical
fumes.
- Take pictures
of the damage--both to the house and its contents--for insurance
purposes.
Remember to
help your neighbors who may require special assistance--infants,
the elderly, and people with disabilities.
INSPECTING
UTILITIES IN A DAMAGED HOME
Check for gas
leaks--If you smell gas or hear a blowing or hissing noise, open
a window and quickly leave the building. Turn off the gas at the
outside main valve if you can and call the gas company from a neighbor's
home. If you turn off the gas for any reason, it must be turned
back on by a professional.
Look for electrical
system damage--If you see sparks or broken or frayed wires, or if
you smell hot insulation, turn off the electricity at the main fuse
box or circuit breaker. If you have to step in water to get to the
fuse box or circuit breaker, call an electrician first for advice.
Check for sewage
and water lines damage--If you suspect sewage lines are damaged,
avoid using toilets and call a plumber. If water pipes are damaged,
contact the water company and avoid using water from the tap. You
can obtain safe water by melting ice cubes.
