ATLANTA, Ga. (Atlanta News First) - When temperatures drop and heating systems fail, the choices homeowners make could save their lives, according to CDC data showing more than 100,000 people go to emergency rooms each year for carbon monoxide poisoning.

Several common heating methods produce dangerous carbon monoxide levels:

• Never use a generator indoors. Keep generators at least 20 feet from the home and never run them in garages, even with doors open.
• Never use stoves or ovens to heat homes. Don’t burn charcoal or grills inside buildings.
• Space heaters, fireplaces and wood stoves require proper ventilation. Crack a window to prevent toxic gas buildup.

• Clear snow and debris from outdoor gas furnaces. Blocked vents can cause dangerous gas leaks.
• When heating systems fail, close off extra rooms and stuff towels or rags under doors. Close blinds or curtains to retain heat.
• Never leave space heaters running while sleeping. Keep heaters at least three feet away from flammable materials. Plug heaters directly into outlets rather than extension cords.

Carbon monoxide symptoms include headache, dizziness and nausea. Anyone experiencing these symptoms should get outside immediately and call 911.

Experts recommend installing carbon monoxide detectors on every floor of homes.
