Winter Safety For Schools
Children can be especially susceptible to the dangers associated with winter weather. Their youthful enthusiasm often takes over when common sense and safety should prevail. Even if they are cold, wet, or exhausted they often are not conscious of the potential impact these conditions pose.
School administrators and principals need to be sensitive to the dangers winter weather can pose to children and be prepared. Winter weather procedures and practices need to be established before the onset of the winter season. When formulating a winter weather safety plan consider the following:
The best
source for the latest information is NOAA Weather Radio. Most counties
fall within their coverage area. Commercial radio or television should
also be monitored. Arrangements can also be made with county sheriff's
office to have critical weather forecasts relayed to the school.
All schools
need to have a functional plan in regard to closures due to snow, ice,
or extreme cold.
During the
winter months, guidelines need to be established regarding outside recess
periods. Temperatures and wind chills need to be monitored and criteria
set as to when outside recess will be allowed.
School bus
drivers should receive extra training on driving during winter weather.
Snow and ice can often accumulate quickly and unexpectedly on roads creating
dangerous driving conditions.
With many
households having two working parents today, it may be necessary for some
children to be brought to school early. Schools should make provisions
to allow children inside school buildings as early as possible during cold
weather.
Recommended Winter Attire
Wear loose fitting, lightweight, warm clothing in several layers (the trapped air between the layers insulates). Layers can be removed to avoid perspiration and subsequent chill. Outer garments should be tightly woven, water repellent, and hooded. Wear a hat (half of body heat is lost through the top of the head). Cover the mouth with scarves to protect lungs from cold air. Mittens, snug at the wrist, are better than gloves. Gloves allow your fingers to cool much faster than mittens do. Try to stay dry. Do not stay outside for extended periods!
Noaa Weather Radio
Listen to NOAA Weather Radio for the latest weather forecasts before traveling in the winter. The National Weather Service broadcasts weather information, including watches, warnings, and advisories 24 hours a day. Weather radio transmitters have a range of about 40 miles. Almost 90 percent of the population of Illinois is within listening range of a NOAA Weather Radio. Here is a list of radio transmitters that cover Illinois:

Weather Terms
The National Weather Service uses the terms below to convey the weather threat to the public. It is important that everyone understands these terms and knows what actions need to be taken at that time.
WIND CHILL: A calculation of how cold it feels outside when the effects of temperature and wind speed are combined. A strong wind combination with a temperature of just below freezing can have the same effect as a still air temperature about 35 degrees colder.
FREEZING RAIN: Rain that freezes when it hits the ground, creating a coating of ice on roads and walkways.
SLEET: Rain that turns to ice pellets before reaching the ground. Sleet bounces when hitting a surface and does not stick to objects. An accumulation of sleet can make roads slick and hazardous.
Watches, Warnings, And Advisories
WINTER STORM WATCH: Indicates severe winter weather such as heavy snow or ice is possible within the next day or two. Prepare now!
WINTER STORM WARNING: Indicates severe winter weather conditions are occurring, imminent, or highly likely. Stay indoors!
Heavy Snow
Warning: Snowfall of six inches or more.
Ice Storm
Warning: Heavy accumulations of ice will create extremely dangerous travel
and damage trees and power lines.
Blizzard
Warning: Snow and strong winds will combine to produce blinding snow, near
zero visibility, deep drifts, and life threatening wind chill.
Winter Weather Advisory: Indicates winter weather conditions will cause significant inconveniences and may be hazardous...especially to motorists. Use caution!
SNOW ADVISORY:
Snowfall of three to five inches.
WIND CHILL
ADVISORY: Dangerous wind chills of 35 below zero or colder.
FREEZING
RAIN/SLEET ADVISORY: Light accumulations of ice will cause hazardous travel.
BLOWING/DRIFTING
SNOW ADVISORY: Poor visibility and hazardous driving conditions.
Remember these terms because the next time you hear them, your life and the lives of others may depend upon it!!
Extreme Cold
Extreme cold temperatures in Illinois pose a substantial danger during the winter months. Prolonged exposure to the cold can cause frostbite, hypothermia, or even death. Persons most susceptible to extreme cold are infants and the elderly.
FROSTBITE is a severe reaction to cold exposure of the skin that can permanently damage fingers, toes, the nose, and ear lobes. Symptoms are loss of feeling and a white or pale appearance to the skin. If these symptoms are apparent, seek medical help immediately. If medical help is not immediately available, slowly rewarm the affected areas. If the victim is also showing signs of hypothermia, always warm the body core before the extremities.
Hypothermia (Low Body Temperature) is a condition brought on when the body temperature drops to less than 95 degrees F. Symptoms include slow or slurred speech, incoherence, memory loss, disorientation, uncontrollable shivering, drowsiness, repeated stumbling, and apparent exhaustion. If these symptoms are detected, take the person's temperature. If below 95 degrees F, immediately seek medical help. If medical aid is not available, begin warming the person slowly. Always warm the body core/trunk first. If needed, use your own body heat to warm the victim. Get the person into dry clothing, and wrap them in a warm blanket covering the head and neck. Do not give the person alcohol, drugs, coffee, or any hot beverage or food; warm broth is better. Do not warm extremities (arms and legs) first. This drives the cold blood toward the heart and can lead to heart failure.
Be Aware!!
Cold weather puts a strain on your heart, even without exercise. Be careful when shoveling snow, pushing a car, or performing other tasks. Regardless of your age or physical condition, avoid overexertion in the winter.
Wind Chill
Most of the time, cold is judged in terms of a thermometer reading. With people and other living things though, both temperature and wind speed are needed to produce a "wind chill factor". The wind chill is based on the rate of heat loss from exposed skin caused by the combined effects of the wind and cold. As the wind increases, heat is carried away from the body at an accelerated rate, driving down the body temperature. The wind chill shows how cold the wind makes exposed flesh feel and is a good way to determine the potential of frostbite or hypothermia.
Remember...wind chill temperatures apply only to people and other living things. If the temperature is 35 degrees F and the wind chill is 10 degrees F, objects such as pipes or cars will only cool to 35 degrees F. The wind chill factor does not apply to non-living objects.

Read right and down from the calm-air line. For example, a temperature of 0 degrees F. combined with a 20 mph wind, has an equivalent cooling effect of -39 degrees F.
Home Heating Tips
Conserve
fuel if necessary by keeping your house cooler than normal. Temporarily
"close off" heat to some rooms.
Hang blankets
over windows at night (let the sun shine in during the day). Stuff cracks
around doors with rugs, newspapers, towels, or other such materials.
When using
kerosene heaters, maintain ventilation to avoid build-up of toxic fumes.
Refuel kerosene heaters outside and keep them at least three feet away
from flammable objects.
If you have
a fireplace, stock an ample supply of wood that is easy to get to during
a storm. Use a screen. Do not leave unattended, especially at night.
If you have
a small camp stove, keep ample fuel. When in use ensure that it is well
ventilated.
Winter Deaths: Everyone is potentially at risk with the actual threat depending upon individual situations. Recent winter death statistics in the United States indicate the following: Related to ice and snow: About 70% occur in automobiles; 25% are people caught out in the storm; and the majority are males over 40 years old. Related to exposure to cold: 50% are people over 60 years old; over 75% are males; and about 20% occur in the home.
Water Pipes
Frozen water pipes aren't life threatening, however frozen or broken water pipes do cause damage to homes each winter. If pipes in the walls aren't properly insulated; they can freeze and rupture. (An eighth-of-an-inch crack in a pipe can release up to 250 gallons of water a day, soaking floors, rugs, and furniture.)
To prevent the mess and aggravation frozen pipes cause, protect your home or apartment by following the simple steps below.
Before Cold Weather
Locate and
insulate pipes most susceptible to freezing--typically those near outer
walls, in crawl spaces, or in the attic. Insulation made especially for
this purpose is available.
Wrap pipes
with heat tape (UL approved).
Seal any
leaks that allow cold air inside where pipes are located.
Disconnect
garden hoses and, shut off and drain water from pipes leading to outside
faucets. This reduces the chance of freezing in the short span of pipe
just inside the house.
When It's Cold
Let hot and
cold water trickle at night from a faucet on an outside wall.
Open cabinet
doors to allow more heat to get to uninstalled pipes under a sink or appliance
near an outer wall.
Make sure
heat is left on and set no lower than 55 degrees.
If you plan
to be away: (1) Have someone check your house daily to make sure the heat
is still on to prevent freezing, or (2) drain and shut off the water system
(except indoor sprinkler systems).
If Pipes Freeze
Make sure
you and your family know how to shut off the water, in case pipes burst.
Stopping the flow of water can minimize the damage to your home. Call a
plumber and contact your insurance agent.
Never try
to thaw a pipe with an open flame or torch.
Always be
careful of the potential for electric shock in and around standing water.
Prepare Now Before The Winter Storm Strikes...
At Home And At Work
The primary concerns are the potential loss of heat, power, telephone service, and a shortage of supplies if storm conditions continue for more than a day.
Have Available:
Flashlight
and extra batteries.
Battery-powered
NOAA Weather Radio and portable (AM-FM) radio to receive emergency information.
These may be your links to the outside world.
Extra food
and water. High energy food, such as dried fruit or candy, and food requiring
no cooking or refrigeration is best.
Extra supply
of medicine and baby items.
First-aid
kit.
Heating fuel.
Fuel carriers may not reach you for days after a severe winter storm.
Emergency
heating source, such as a fireplace, wood stove, space heater, etc. Learn
to use them properly to prevent a fire. Have proper ventilation.
Fire extinguisher
and smoke detector. Test units regularly to ensure they are working properly.
On The Farm
Move animals
to sheltered areas.
Haul extra
feed to nearby feeding areas.
Have a water
supply available. Most animal deaths in winter storms occur from dehydration.
In Cars And Trucks
Plan your
travel and check the latest weather reports on current conditions!
Fully check
and winterize your vehicle before the winter season begins.
Carry a WINTER
STORM SURVIVAL KIT: blankets/sleeping bags; high-calorie, non-perishable
food; flashlight with extra batteries; first aid kit; knife; extra clothing
to keep dry; a large empty can and plastic cover with tissues and paper
towels for sanitary purposes; a smaller can and water-proof matches to
melt snow for drinking water; sack of sand (or cat litter); shovel; windshield
scraper and brush; tool kit; tow rope; booster cables; water container;
compass and road maps.
Keep your
gas tank near full to prevent ice in the tank and fuel lines which could
leave you stranded.
Try not to
travel alone.
Let someone
know your primary and alternate routes and anticipated timetable.
When Caught In A Winter Storm...
Avoid overexertion, such as shoveling heavy snow, pushing a car, or walking in deep snow. The strain from the cold and the hard labor could cause a heart attack. Sweating could lead to a chill and even hypothermia.
Outside
Seek shelter
to stay dry.
Cover all
exposed parts of the body.
If no shelter
is nearby, prepare a lean-to, wind-break, or snow cave for protection from
the wind. Build a fire for heat and to attract attention.
Do not eat
snow as it will lower your body temperature. Melt it first.
In A Vehicle
If you have
a cellular phone, call for help.
Stay in your
vehicle. Disorientation occurs quickly in wind-driven snow and cold.
Run the engine
(after making sure the exhaust pipe is not blocked and opening windows
a little for fresh air to avoid carbon monoxide poisoning) about ten minutes
each hour for heat.
Make yourself
visible to rescuers. Turn on the dome light at night when running engine.
Tie a colored cloth (preferably red) to your antenna or door. Raise the
hood indicating trouble after snow stops falling.
Exercise
from time to time by vigorously moving arms, legs, fingers, and toes to
keep blood circulating and to keep warm.
At Home Or In A Building
Stay indoors.
When using alternative heat from a fireplace, wood stove, space heater,
etc. use safeguards and ensure proper ventilation.
If you have
no heat, close off unneeded rooms and place towels or rags under the doors.
Cover windows at night.
Eat to supply
heat and drink to avoid dehydration.
Wear layers
of loose-fitting, light-weight, warm clothing. Remove layers to avoid overheating,
perspiration and subsequent chill.
Winter Driving Tips
To minimize the possibility of break down, winterize your vehicle following the suggested maintenance schedule included in the owners manual or have your vehicle serviced by a reputable dealer, garage, or mechanic.
Check your wipers, tires (use snow tires if possible), lights, and fluid levels (radiator, windshield washer, power steering, oil and brakes) regularly. Make sure the brakes and transmission are working properly. Lubricate door and trunk locks with lock lubricant to prevent them from freezing.
During a winter storm ask yourself, "is this trip really necessary?" If you decide the trip cannot be delayed, check on weather conditions along your travel route. Listen to weather forecasts on TV, local radio stations, or NOAA Weather Radio. Call 1-800-452-IDOT to get current road conditions for Illinois' interstate and freeway systems. Information is updated every two hours during a storm.
Do not leave without a WINTER STORM SURVIVAL KIT. The page titled "PREPARE NOW" lists the recommended contents of a kit.
Tell someone at home (a friend, relative, or co-worker) that you are taking a trip, where you are going, the routes you will travel, and when you expect to arrive. When you reach your destination, make a call to report that you have arrived.
Before you leave town, fill your gas tank. While traveling, frequently re-fill the gas tank. The stops will relieve tense muscles. When you stop, don't flaunt large amounts of cash. Keep valuable items out of sight. Avoid talking with strangers. Stop at well-lighted, well-traveled facilities.
If your vehicle breaks down, pull as far off the road as possible. Your greatest personal danger at this point is that of being hit by passing cars. Don't panic. Use common sense! The steps on the page titled "WHEN CAUGHT IN A WINTER STORM..." in a vehicle will help you survive.
Winter Vehicle Operation
Winter driving is often the most difficult due to blowing snow, icy slick spots and fewer daylight hours. When you are on the road:
Buckle your
seat belts!
Be prepared
to turn back and seek shelter if conditions become threatening.
In fog, drive
with your headlights set on dim, or use foglights. If the fog is too dense,
pull off the roadway and stop. Do not drive at five or ten miles per hour.
In rain,
fog, snow, or sleet, do not overdrive your headlights. Stay within the
limits of your vision.
Keep your
windows clear of snow and ice. Do not start until your windshield is defrosted.
Drive slower
and increase your following distance. Your speed should be adjusted for
the conditions and match the flow of traffic.
Roadway conditions
may vary depending on the sun, shade, or roadway surface. Watch for slick
spots especially under bridges, on overpasses and in shaded spots. Be prepared
to react physically and mentally.
If the pavement
is snow or ice covered, start slowly and brake gently. Begin braking early
when you come to an intersection. If you start to slide, ease off the gas
pedal or brakes. Steer into the direction of the skid until you feel you
have regained traction then straighten your vehicle.
When a snow
plow is coming towards you, allow plenty of room for the plow to pass.
When the center line is being cleared and salted the plow tip may be on
or over the line. Snow plows are big, heavy pieces of equipment. So play
it safe, give them room to pass.
When you
approach a snow plow from behind, pass with care and only when you can
see the road ahead of the plow. You should not try to pass in blowing snow,
there may be a vehicle in that cloud of snow. Allow more distance between
you and the plow, they may be spreading salt.
Be alert
when you approach a cloud of snow which covers the road, especially on
passing lanes of interstates or freeways. A snow plow may be at work clearing
the lane or preparing to turn around.
Be careful
after a minor rear end accident. If you are bumped from behind and you
do not feel comfortable exiting your vehicle, motion the other driver and
drive to the nearest police station, 24-hour store, service station, hospital,
or fire station.
