Colder weather means a higher risk of carbon monoxide poisoning. Here's how to protect yourself

Calls about carbon monoxide poisoning to the Oklahoma Poison Center Carbon increase as cold weather moves into the state and people begin using their furnaces and fireplaces, according to a press release from the center.

Carbon monoxide is found in fumes produced when fuel is burned in gas furnaces, water heaters, vehicles, small engines, stoves, lanterns and grills. According to the Oklahoma Poison Center, proper ventilation is essential when these are used.

“People will occasionally attempt to heat their home with grills or stoves,” Kristie Edelen, Poison Center managing director, said in the release. “This is extremely dangerous; there is no way these attempts at heating can be made safe.” Edelen added.”

Chimney damage or blockage, vents or exhaust can cause carbon monoxide to build up indoors. The center advises against using a generator, charcoal grill, camp stove or other gasoline or charcoal-burning devices indoors or near a window.
