Preparation Steps
- Insulate your home. Seal drafts around windows and doors. Add insulation to pipes, especially those in unheated areas.
- Stock emergency heating supplies. Have blankets, sleeping bags, and hand warmers ready.
- Prepare an alternative heat source. Know how to safely use a fireplace or propane heater with proper ventilation.
- Winterize your vehicle. Carry a blanket, ice scraper, sand or cat litter for traction, jumper cables, and a phone charger.
- Build a winter emergency kit. Water, food, medications, flashlights, hand warmers, and a weather radio.
- Know the signs of hypothermia and frostbite. Early recognition saves lives.
Immediate Actions
If caught in extreme cold:
- Get to shelter immediately. Even a car provides protection from wind.
- Layer clothing. Use the COLD method: Clean, Avoid Overheating, Loose layers, Dry.
- Protect extremities. Hands, feet, ears, and nose lose heat fastest.
- Stay dry. Wet clothing accelerates heat loss up to 25x faster than dry clothing.
- Eat and drink warm fluids. Food provides energy for generating body heat.
- Avoid alcohol. It causes blood vessels to dilate, accelerating heat loss.
- Move. Physical activity generates body heat. Avoid sweating — it wets your clothes.
What to Avoid
- Do not run heating equipment designed for outdoor use indoors. Carbon monoxide risk.
- Do not rub frostbitten skin. This damages tissue.
- Do not eat snow for hydration — melting snow consumes body heat.
- Do not ignore shivering — it is your body's warning sign.
- Do not travel in a blizzard unless absolutely necessary.
Supplies Needed
- Thermal base layers (wool or synthetic — not cotton)
- Waterproof outer shell jacket and pants
- Insulated waterproof boots
- Wool socks (multiple pairs)
- Gloves and insulated mittens
- Balaclava or wool hat covering ears
- Hand warmers and foot warmers
- Emergency space blanket
- High-calorie snacks (nuts, chocolate, jerky)
- Thermos with hot liquid
- Portable propane heater (with CO detector)
Recovery Steps
- Treat hypothermia gently. Move the person to a warm area, remove wet clothing, and wrap in dry blankets. Give warm beverages if conscious. Seek medical attention.
- Do not rewarm frostbite in the field if there is risk of refreezing. Seek medical care.
- Check pipes. Inspect for burst pipes after a hard freeze.
- Monitor for CO. If you used alternative heating, check your carbon monoxide detectors.
