Extreme Cold

Near freezing temperatures are considered “extreme cold.” Whenever temperatures drop below normal and as wind speed increases, heat can leave your body more rapidly. These weather-related conditions may lead to serious health problems. Extreme cold is a dangerous situation that can bring on health emergencies in susceptible people, such as those without shelter or who are stranded, or who live in a home that is poorly insulated or without heat.  Here is what you can do:

Plan Ahead

Prepare for extremely cold weather every winter.  Make sure you are prepared for extreme temperatures by pre-planning to store supplies in your home and in your car.

Emergency Supply List

  • an alternate way to heat your home during a power failure:
    • dry firewood for a fireplace or wood stove, or
    • kerosene for a kerosene heater
  • furnace fuel (coal, propane, or oil)
  • electric space heater with automatic shut-off switch and non-glowing elements
  • blankets
  • matches
  • multipurpose, dry-chemical fire extinguisher
  • first aid kit and instruction manual
  • flashlight or battery-powered lantern
  • battery-powered radio
  • battery-powered clock or watch
  • extra batteries
  • non-electric can opener
  • snow shovel
  • rock salt
  • special needs items (diapers, hearing aid batteries, medications, etc.)

Keep several days’ supply of these items:

  • Food that needs no cooking or refrigeration, such as bread, crackers, cereal, canned foods, and dried fruits. Remember baby food and formula if you have young children.
  • Water stored in clean containers, or purchased bottled water (5 gallons per person) in case your water pipes freeze and rupture.
  • Medicines that any family member may need.

If your area is prone to long periods of cold temperatures, or if your home is isolated, stock additional amounts of food, water, and medicine.

Listen to weather forecasts regularly, and check your emergency supplies whenever a period of extreme cold is predicted.

If you plan to use a fireplace or wood stove for emergency heating, have your chimney or flue inspected each year. Ask your local fire department to recommend an inspector, or find one in the yellow pages of your telephone directory under “chimney cleaning.”

Also, if you’ll be using a fireplace, wood stove, or kerosene heater, install a smoke detector and a battery-operated carbon monoxide detector near the area to be heated. Test them monthly, and replace batteries twice yearly.

Your ability to feel a change in temperature decreases with age, and older people are more susceptible to health problems caused by cold. If you are over 65 years old, place an easy-to-read thermometer in an indoor location where you will see it frequently, and check the temperature of your home often during the winter months.

Insulate any water lines that run along exterior walls so your water supply will be less likely to freeze. To the extent possible, weatherproof your home by adding weather-stripping, insulation, insulated doors and storm windows, or thermal-pane windows.

If you have pets, bring them indoors. If you cannot bring them inside, provide adequate shelter to keep them warm and make sure that they have access to unfrozen water.

Prepare Your Car for Winter

You can avoid many dangerous winter travel problems by planning ahead. Have maintenance service on your vehicle as often as the manufacturer recommends. In addition, every fall:

  • Have the radiator system serviced, or check the antifreeze level yourself with an antifreeze tester. Add antifreeze, as needed.
  • Replace windshield-wiper fluid with a wintertime mixture.
  • Replace any worn tires, and check the air pressure in the tires.

During winter, keep the gas tank near full to help avoid ice in the tank and fuel lines.

Winter Survival Kit for Your Car

Equip your car with these items:

  • blankets
  • first aid kit
  • a can and waterproof matches (to melt snow for water)
  • windshield scraper
  • booster cables
  • road maps
  • mobile phone
  • compass
  • tool kit
  • paper towels
  • bag of sand or cat litter (to pour on ice or snow for added traction)
  • tow rope
  • tire chains (in areas with heavy snow)
  • collapsible shovel
  • container of water and high-calorie canned or dried foods and a can opener
  • flashlight and extra batteries
  • canned compressed air with sealant (for emergency tire repair)
  • brightly colored cloth

Indoor Safety

Heat Your Home Safely

If you plan to use a wood stove, fireplace, or space heater, be extremely careful. Follow the manufacturer’s instructions as well as the home safety measures on page 3, and remember these safety tips:

  • Use fireplace, wood stoves, or other combustion heaters only if they are properly vented to the outside and do not leak flue gas into the indoor air space.
  • Do not burn paper in a fireplace.
  • Ensure adequate ventilation if you must use a kerosene heater.
  • Use only the type of fuel your heater is designed to use—don’t substitute.
  • Do not place a space heater within 3 feet of anything that may catch on fire, such as drapes, furniture, or bedding, and never cover your space heater.
  • Never place a space heater on top of furniture or near water.
  • Never leave children unattended near a space heater.
  • Make sure that the cord of an electric space heater is not a tripping hazard but do not run the cord under carpets or rugs.
  • Avoid using extension cords to plug in your space heater.
  • If your space heater has a damaged electrical cord or produces sparks, do not use it.
  • Store a multipurpose, dry-chemical fire extinguisher near the area to be heated.
  • Protect yourself from carbon monoxide (CO) poisoning by installing a battery-operated CO detector and never using generators, grills, camp stoves, or similar devices indoors.

Light and Cook Safely

If there is a power failure:

  • Use battery-powered flashlights or lanterns rather than candles, if possible.
  • Never leave lit candles unattended.
  • Never use a charcoal or gas grill indoors—the fumes are deadly.

Never use an electric generator indoors, inside the garage, or near the air intake of your house because of the risk of carbon monoxide poisoning:

  • Plug in appliances to the generator using individual heavy-duty, outdoor-rated cords.
  • Do not use the generator or appliances if they are wet because of the risk of electrocution.
  • Do not store gasoline indoors where the fumes could ignite.

Conserve Heat

You may need fresh air coming in for your heater or for emergency cooking arrangements. However, if you don’t need extra ventilation, keep as much heat as possible inside your home. Avoid unnecessary opening of doors or windows. Close off unneeded rooms, stuff towels or rags in cracks under doors, and close draperies or cover windows with blankets at night.

Monitor Body Temperature

Infants less than one year old should never sleep in a cold room because (1) infants lose body heat more easily than adults; and (2) unlike adults, infants can’t make enough body heat by shivering. Provide warm clothing for infants and try to maintain a warm indoor temperature. If the temperature cannot be maintained, make temporary arrangements to stay elsewhere. In an emergency, you can keep an infant warm using your own body heat. If you must sleep, take precautions to prevent rolling on the baby. Pillows and other soft bedding can also present a risk of smothering; remove them from the area near the baby.

Older adults often make less body heat because of a slower metabolism and less physical activity. If you are over 65 years of age, check the temperature in your home often during severely cold weather. Also, check on elderly friends and neighbors frequently to ensure that their homes are adequately heated.

Keep a Water Supply

Extreme cold can cause water pipes in your home to freeze and sometimes rupture. When very cold temperatures are expected:

  • Leave all water taps slightly open so they drip continuously.
  • Keep the indoor temperature warm.
  • Improve the circulation of heated air near pipes. For example, open kitchen cabinet doors beneath the kitchen sink.

If your pipes do freeze, do not thaw them with a torch. Instead, thaw them slowly by directing the warm air from an electric hair dryer onto the pipes.

If you cannot thaw your pipes, or the pipes are ruptured, use bottled water or get water from a neighbor’s home. As an emergency measure—if no other water is available—snow can be melted for water. Bringing water to a rolling boil for one minute will kill most microorganisms or parasites that may be present, but won’t remove chemical pollutants sometimes found in snow.

Eat and Drink Wisely

Eating well-balanced meals will help you stay warmer. Do not drink alcoholic or caffeinated beverages—they cause your body to lose heat more rapidly. Instead, drink warm, sweet beverages or broth to help maintain your body temperature. If you have any dietary restrictions, ask your doctor.

Outdoor Safety

When the weather is extremely cold, and especially if there are high winds, try to stay indoors. Make any trips outside as brief as possible, and remember these tips to protect your health and safety:

Dress Warmly and Stay Dry

Adults and children should wear:

  • a hat
  • a scarf or knit mask to cover face and mouth
  • sleeves that are snug at the wrist
  • mittens (they are warmer than gloves)
  • water-resistant coat and boots
  • several layers of loose-fitting clothing

Be sure the outer layer of your clothing is tightly woven, preferably wind resistant, to reduce body-heat loss caused by wind. Wool, silk, or polypropylene inner layers of clothing will hold more body heat than cotton. Stay dry—wet clothing chills the body rapidly. Excess perspiration will increase heat loss, so remove extra layers of clothing whenever you feel too warm. Also, avoid getting gasoline or alcohol on your skin while de-icing and fueling your car or using a snow blower. These materials in contact with the skin greatly increase heat loss from the body. Do not ignore shivering. It’s an important first sign that the body is losing heat. Persistent shivering is a signal to return indoors.

Avoid Exertion

Cold weather puts an extra strain on the heart. If you have heart disease or high blood pressure, follow your doctor’s advice about shoveling snow or performing other hard work in the cold. Otherwise, if you have to do heavy outdoor chores, dress warmly and work slowly. Remember, your body is already working hard just to stay warm, so don’t overdo it.

Understand Wind Chill

The Wind Chill index is the temperature your body feels when the air temperature is combined with the wind speed. It is based on the rate of heat loss from exposed skin caused by the effects of wind and cold. As the speed of the wind increases, it can carry heat away from your body much more quickly, causing skin temperature to drop. When there are high winds, serious weather-related health problems are more likely, even when temperatures are only cool.

 Avoid Ice

Walking on ice is extremely dangerous. Many cold-weather injuries result from falls on ice-covered sidewalks, steps, driveways, and porches. Keep your steps and walkways as free of ice as possible by using rock salt or another chemical de-icing compound. Sand may also be used on walkways to reduce the risk of slipping.

Be Safe During Recreation

Notify friends and family where you will be before you go hiking, camping, or skiing. Do not leave areas of the skin exposed to the cold. Avoid perspiring or becoming overtired. Be prepared to take emergency shelter. Pack dry clothing, a two-wave radio, waterproof matches and paraffin fire starters with you. Do not use alcohol and other mood altering substances, and avoid caffeinated beverages. Avoid walking on ice or getting wet. Carefully watch for signs of cold-weather health problems.

Be Cautious About Travel

  • Listen for radio or television reports of travel advisories issued by the National Weather Service.
  • Do not travel in low visibility conditions.
  • Avoid traveling on ice-covered roads, overpasses, and bridges if at all possible.
  • If you must travel by car, use tire chains and take a mobile phone with you.
  • If you must travel, let someone know your destination and when you expect to arrive. Ask them to notify authorities if you are late.
  • Check and restock the winter emergency supplies in your car before you leave.
  • Never pour water on your windshield to remove ice or snow; shattering may occur.
  • Don’t rely on a car to provide sufficient heat; the car may break down.
  • Always carry additional warm clothing appropriate for the winter conditions.

What to Do if You Get Stranded

Staying in your vehicle when stranded is often the safest choice if winter storms create poor visibility or if roadways are ice covered. These steps will increase your safety when stranded:

  • Tie a brightly colored cloth to the antenna as a signal to rescuers and raise the hood of the car (if it is not snowing).
  • Move anything you need from the trunk into the passenger area.
  • Wrap your entire body, including your head, in extra clothing, blankets, or newspapers.
  • Stay awake. You will be less vulnerable to cold-related health problems.
  • Run the motor (and heater) for about 10 minutes per hour, opening one window slightly to let in air. Make sure that snow is not blocking the exhaust pipe—this will reduce the risk of carbon monoxide poisoning.
  • As you sit, keep moving your arms and legs to improve your circulation and stay warmer.
  • Do not eat unmelted snow because it will lower your body temperature.
  • Huddle with other people for warmth.
