In
the event of a tornado you have only a short amount of time to make
life-or-death decisions. Planning in advance and quick response are the keys to
surviving a tornado.
Be
Prepared
Conduct
tornado drills each season. Designate an area in the home to serve as a shelter,
and practice with the whole family the drill of going to that area in response
to a tornado threat.
Discuss
with the family members the differences between a "tornado watch" and
a "tornado warning".
Be
sure to have all necessary supplies on hand for a disaster. Refer to the
Disaster
Supplies Kit page for further information.
Develop
an Emergency Communication Plan
In
the event that family members are separated from one another during a tornado,
especially applicable during the day when adults are at work and children are in
school, have a communication plan developed to aide in getting everyone back
together. Ask an out-of-state relative or friend to serve as your family
contact. It is often easier to call long distance after a disaster. Make sure
everyone in your family knows the name, address, and telephone number of the
contact person.
Tornado
Watches and Warnings
A
Tornado Watch is issued by the National Weather Service when
tornados are possible in your area and the conditions in the region specified
are favorable for the development of tornados. Remain alert for approaching
storms. This is the time to remind family members where the safest places within
your home are located, and listen to the radio or television for further
developments and reports.
A
Tornado Warning is issued when a tornado has been sighted or indicated
by the weather radar. This is the time to take immediate action.
Mobile
Homes
Mobile
homes are particularly vulnerable to tornados and severe storms. 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 a ditch or low-lying area a safe
distance away from the unit.
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.
-
Tornados
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 the 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:
-
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 out drive a tornado in a car or truck. Tornados 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 building 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, such as 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 advise.
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.
Mitigation
Mitigation
includes any activities that prevent an emergency, reduce the chance of an
emergency happening, or lessen the damaging
effects of unavoidable emergencies. Investing in preventive mitigation steps
now, such as checking local building codes and ordinances about wind-resistant
designs and strengthening un-reinforced masonry, will help reduce the impact of
tornados in the future. For more information on mitigation, contact you local
emergency management office.
