Tornado Safety
Each year about a thousand tornadoes touch down in the US. Only a small percentage actually strike occupied buildings, but every year a number of people are killed or injured. The chances that a tornado will strike a building that you are in are very small, however, and you can greatly reduce the chance of injury by doing a few simple things.
Be
alert to what is happening outside as well. Here are some of the things that
people describe when they tell about a tornado experience: Encourage your family members to
plan for their own safety in many different locations. It is important to make
decisions about the safest places well BEFORE you ever have to go to them. The best places are: Wherever it is, the shelter
should be well known by each member of the family. If you and your family
will conduct annual emergency drills (fire, tornado, etc), everyone will
remember what to do and where to go when a tornado is
approaching--automatically and without panic. Choose a friend or family
member in another part of town or elsewhere to be a "contact
person" that will be called by everyone should the family members
become separated. The Red Cross suggests that
you assemble a "disaster supplies kit" that you keep in your
shelter area. It should contain:
Leave auditoriums, gyms and
other free-span rooms, exiting in an orderly fashion. Go to the interior
rooms and halls on the lowest floor, but avoid halls that open to the
outside in any direction. If there are no interior hallways, avoid those
that open to the southwest, south, or west, since that is the usually the
direction the tornado will come. Stay away from glass, both in windows and
doors. Crouch down and make as small a "target" as possible. If
you have something to cover your head, do so, otherwise, use your hands.
Don't assume that there will always be a teacher or other adult there to
tell you what to do--if there is, you should follow their direction, but you
need to know these things too. TO AND FROM SCHOOL, WORK, OR
AFTER-SCHOOL ACTIVITIES: If really severe weather is
expected, your school may be dismissed early in order that you can reach
home before the worst of the weather reaches the area. If you are on foot or
riding a bike, it is doubly important that you go home immediately, and not
linger with your friends. If caught in the open, you should seek a safe
place immediately. The chances of encountering falling trees, power lines,
and lightning is greater than encountering the tornado itself. The basement
of a sturdy building would be best, but lying flat in a ditch or low-lying
area may be the only thing available. A culvert in a ditch MAY be a good
choice if there is no rain, but if there IS rain, flash flooding may be more
dangerous and likely than the tornado. Interior rooms and halls are the best
locations in large buildings. Central stairwells are good, but elevators are
not. If the building loses power, you may be in the elevator for a long
time. Stay away from glass walls and windows, no matter how small. Most tornado deaths occur in cars and mobile
homes. If you live in a mobile home park, you should find out from the
manager where you should go in the event of a tornado--but don't wait until
you really need the information--ask him/her on a nice day! Mobile home
parks may have a designated tornado shelter, or a steel reinforced concrete
laundry room. If they don't, you need to find another substantial structure
that you can reach very quickly. You may have only seconds to get to it. The
photo below shows what an 60-80 mph wind can do to a mobile home. At 100
mph, they may start to disintegrate. 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, theaters, and warehouses. Crouch
down and cover your head. Deaths have occurred in large, single story
department stores. They have occurred inside the building when the roof or
wide span brick walls, which collapsed. A corner would be safer than the
middle of the wall. A bathroom, closet, office, or maintenance room with
short walls would be the safest area, especially if it was on the north or
east side of the building. Source: 
One
of the most important things you can do to prevent being injured in a tornado is
to be to the onset of severe weather. Most deaths and
injuries happen to people who are unaware and uninformed. Young children or the
mentally challenged may not recognize a dangerous situation. The ill, elderly,
or invalid may not be able to reach shelter in time. Those who ignore the
weather because of indifference or overconfidence may not perceive the danger.
Stay aware, and you will stay alive!
If you see a tornado and it is not
moving to the right or to the left relative to trees or power poles in the
distance, it may be moving towards you! Remember that although tornadoes usually
move from southwest to northeast, they also move towards the east, the
southeast, the north, and even northwest.
IN HOMES OR OTHER SMALL BUILDINGS
IN SCHOOLS
Peak time for tornadoes to strike varies from region to region. In some
southeastern states, early morning tornadoes are almost as common as late
afternoon ones. In western and northern states, peak hours are from 3 to 7
PM, just at the end of the school, but including the hours of afterschool
activities.
IN HIGH-RISE BUILDINGS
MOBILE HOMES
SHOPPING CENTERS, HOSPITALS, AND FACTORIES
Is it likely that a tornado will strike your home or school? No. But being
ready for the possibility will keep you safer!
Deaths and injuries from tornadoes have dropped dramatically in the past 50
years. Casualties numbers are holding steady as scientists learn more about
tornadoes and develop the technologies that detect them sooner. Forecasters
must continue to improve techniques because the population is increasing.
The National Weather Service, Storm Prediction Center and television and
radio weather people have taken full advantage of the advancements in
tornado prediction to improve warnings.
In addition, many people generously donate their time and expertise to help
protect their neighbors and communities in another way--by tornado and
severe storm "spotting." "Spotters" combine an interest
in the weather, a willingness to serve and often, ham radio experience to
make tornado prone areas safer for all. Spotting can provide a focus to a
person's interest in the weather, and ham radio helps you meet other
like-minded people. It is not often that something that starts out as a
hobby can potentially do so much good.
