Key Safety Rules |
| |
- In a home
or building, move to a pre-designated shelter, such as a basement.
- If an
underground shelter is not available, move to a small interior
room or hallway on the lowest floor and get under a sturdy piece
of furniture. Put as many walls as possible between you and the
outside.
- Stay away
from windows.
- If caught
outside in a vehicle, do not try to outrun a tornado. Get out of
the vehicle and seek safe shelter. Lie flat in a nearby ditch or
depression and cover your head with your hands.
- Be aware of
flying debris. Flying debris from tornadoes causes most deaths and
injuries.
- Mobile
homes, even if tied down, offer little protection from tornadoes.
You should leave a mobile home and go to the lowest floor of a
sturdy nearby building or a storm shelter.
-
Occasionally, tornadoes develop so rapidly that advance warning is
not possible. Remain alert for signs of an approaching tornado
such as a dark, often greenish sky, large hail, or a loud roar
similar to a freight train.

| Before a Tornado: |
| |
- Make a
written or videotaped inventory of household possessions/property
and store in a safe place with insurance policies, documents and
other valuables.
- Identify a
safe location in your home--a basement, center hallway, bathroom
or closet on the lowest floor.
- Take a
first aid class from your local Red Cross Chapter.
- Assemble a
disaster kit including: first aid kit, medications,
battery-powered radio, flashlight, extra batteries, canned food,
can opener, bottled water, sturdy shoes and work gloves.
- Make a
utilities checklist with instructions on how to turn them off.
- Conduct
periodic tornado drills.
- Listen to
your local radio and TV stations for updated storm information and
for instructions if a disaster occurs.
- Check your
homeowners insurance policy to make sure you're covered for damage
due to tornadoes.
|
| |
| After a Tornado: |
| |
- Call your
independent insurance agent as soon as possible.
- Make
temporary repairs to prevent further damage.
- Delay
permanent repairs until your insurer approves reimbursement.
- Get any
necessary construction permits from your community.
- Keep all
receipts.
- Prepare an
inventory of all damaged or destroyed personal property.
- Take photos
of damaged areas.
- Save
remnants of damaged or destroyed property for your insurance
company adjuster.
- Meet with
your adjuster first, before signing anything with contractors,
lawyers or public adjusters.
