(WCPO) -- An invisible killer could be lurking in you home, especially if you use gas, oil or kerosene.
As the cold weather settles in, 9 First Warning Meteorologist Sherry Hughes tells you how to protect yourself from carbon monoxide poisoning.
Cincinnati firefighters respond to carbon monoxide calls more often in winter months than any other time of the year.
Capt. James Kettler said, "Carbon monoxide is a colorless, tasteless gas and without being able to detect it, it's very toxic to humans and animals as well."
Carbon monoxide detectors and smoke alarms can be found in home improvement stores in a range of prices.
Former fireman Barry Hatter now works for Loews, and feels carbon monoxide detectors are the best protection.
"Why take a chance on something that can be really serious when the cost and effort to change all that or detect all that is really minimal?" he said.
If cost is a big factor, some fire departments will give them out by request.
To keep your family safe, it's best to place one carbon monoxide detector on every level of your home, in sleeping areas and in basements.
