Older adults lose body heat more easily than younger people, and babies sleeping in cold rooms are at risk of hypothermia. Set up a safe backup before winter, then keep the heat you have in one room when the furnace stops.
Before winter
- Keep a backup heat source readyExtra blankets and warm coats count, and so does a fireplace with dry firewood or an electric space heater.
- Use an electric space heater with an automatic shut-off switch
- Put battery-powered carbon monoxide alarms in the house
- Keep flashlights and lanterns with fresh batteries in place of candlesCandles start house fires during outages. If you use one, never leave it lit in an empty room.
- Have the heating system serviced by a qualified technician every year
Get ready for a winter without heat
- Set aside extra blankets and warm coats for an outage
- Put fresh batteries in the flashlights and the CO alarms
- Book the yearly heating service
When the heat goes out
- Pick one room to keep warm and close the doors to the rest
- Block the drafts under the doors with towels
- Close the curtains, or cover the windows, at night
- Keep the doors to the outside shut as much as you can
- Never use the stove or oven to heat the house
- Never run a generator, grill or camp stove inside, in the basement or in the garageTheir exhaust carries carbon monoxide, which can kill. A generator goes at least 20 feet from the windows, doors and vents.
- Keep a space heater 3 feet from curtains, bedding and furniturePlug it straight into the wall, never into an extension cord, and keep children away from it.
- Let the faucets drip and open the cabinets under the sinksThe moving water and the warm air keep the pipes from freezing. Thaw a frozen pipe with a hair dryer, never a torch.
Babies and older adults
- Dress a baby in warm sleepwear and keep pillows and soft bedding out of the crib
- Arrange to stay somewhere else if the house can't be kept warm for a baby
- Check the indoor temperature often if you're over 65, and check on older neighbors
- Know the signs of hypothermiaIn adults, look for shivering, exhaustion, confusion, fumbling hands, slurred speech and drowsiness. A baby with hypothermia has bright red, cold skin and very little energy.
If someone's temperature drops below 95°F, get medical help right away. While you wait, move them to the warmest room and take off any wet clothing. Warm the center of the body first: the chest, neck, head and groin. Warm drinks help, but never alcohol, and never give a drink to someone who isn't awake. Hypothermia can set in above 40°F when someone is wet from rain or sweat.
Running a portable generator safely covers the generator in detail, and space heater safety covers placing and plugging in a heater.
FAQ
Is it safe to heat the house with a gas oven?
No. Turning on the stove or oven for heat is never safe.
How do I keep the pipes from freezing without heat?
Let the faucets drip and open the cabinet doors under the sinks. If a pipe freezes, thaw it with a hair dryer.
When is someone too cold to wait it out?
When their temperature is below 95°F, or a baby has bright red, cold skin and very little energy. Get medical help right away.
