QUESTION: Is carbon monoxide more of a threat in winter months?

ANSWER: Carbon monoxide poisoning is always a threat, but tends to happen more often during colder months—causing an average of 430 deaths, 20,000 visits to the emergency room, and more than 4,000 hospitalizations each year in the U.S. The main culprits are unventilated heating, cooking and power sources being used indoors during power outages.

Never use a generator, grill, camp stove or other gasoline, propane, natural gas or charcoal-burning device inside any enclosed area. Such devices should be kept outside and at least 20 feet from open doors, windows and vents.

Because carbon monoxide is both invisible and odorless, installing carbon monoxide alarms in central locations on all levels of your home will provide early warning of accumulating carbon monoxide—and peace of mind all winter long.
