Tornado Safety Rules in Schools
Several
times in recent years, schools have been hit by tornadoes. In most
instances, fortunately, classes were not in session. In some other
instances, where students were present, school officials familiar
with twisters safeguarded the children by taking prompt action just
before the tornadoes hit.
NOAA's
National Weather Service urges that all schools develop plans and
conduct drills to cope with tornadoes--particularly in the South
and central states, where the threat is greatest. Tornado drills
require different actions than fire drills.
Among
details to consider:
- Remember
that the National Weather Service issues a tornado Watch when
the possibility of tornadoes exists, and a tornado Warning when
a tornado has been spotted or indicated on radar. Remember also
there may not be time for a tornado Warning before a twister strikes.
Tornadoes form suddenly. Teachers and students should know the
difference between a Watch and a Warning.
- School
officials at the State and county level should have a plan for
rapid dissemination of tornado Watches and Warnings to every school
in the system--either by radio or telephone.
- Each
school should be inspected and tornado shelter areas designated.
Schools with basements should use these as shelters. Schools without
basements should use interior hallways on the ground floor that
are not parallel to the tornado's path, which is usually from
the southwest. Never use gymnasiums, auditoriums, or other rooms
with wide free-span roofs. Teachers and students should know their
designated shelter areas.
- School
Administrators should establish procedures governing use or non-use
of school buses during tornado Watches and Warnings. Generally
speaking, school buses should continue to operate during tornado
Watches, but not during tornado Warnings. School buses are easily
rolled by tornado winds.
- During
a tornado Watch, specific teachers or other school staff members
should be designated to monitor commercial radio or TV for tornado
Warnings, even if the school has a NOAA Weather Radio tone-alert
system. Weather spotters also should keep an eye on the sky for
dark, rolling clouds, hail, driving rain, or a sudden increase
in wind, in addition to the telltale funnel. Tornadoes are often
obscured by precipitation or darkness. Other public agencies,
too, report tornado sightings.
- A
special alarm system should be designated to indicate a tornado
has been sighted and is approaching. A backup alarm should be
planned for use if electrical power fails--perhaps a battery-operated
bullhorn, an inexpensive hand-cranked siren, or even an old-fashioned
hand-swung bell.
- Specific
teachers should be assigned to round up children on playgrounds
or other outdoor areas during a tornado warning. Otherwise, they
might be overlooked.
- Children
in schoolrooms of weak construction--such as portable or temporary
classrooms--should be escorted to sturdier buildings or to predetermined
ditches, culverts, or ravines, and instructed to lie face down,
hands over head.
- Most
tornado deaths are caused by head injuries.
- When
children are assembled in school basements or interior hallways
during a tornado drill or Warning, they should be instructed
to
respond to a specific command to assume protective postures,
facing interior walls, when the danger in imminent. Such a
command might
be: "Everybody down!" It is essential that this command
be instantly understood and obeyed. Illustrations showing the
protective position should be posted on bulletin boards.
- If
a school bus is caught in the open when a tornado is approaching,
the children should be escorted to a nearby ditch or ravine and
made to lie face down, hands over head. They should be far enough
away so the bus cannot topple on them.
- School-bus
drivers should be regularly drilled in Tornado procedures.
- School
district officials planning new buildings or additions should
keep tornadoes in mind when setting construction standards.

Warning
Signal:____________________________________________
IT
MEANS: A tornado has been sighted. Go at once to the area listed
below. If you see or hear the tornado coming, do not wait for the
Warning Signal--go to your shelter area if there is time, it not,
curl up on the floor and protect yourself as the boy in the picture
is doing. If a tornado comes while you are on the school bus, get
away from the bus and into a nearby ditch or ravine. Lie down, hands
over head.
