What is carbon monoxide?

Carbon monoxide (CO) is a colorless, odorless and tasteless gas. It’s created by insufficient fuel combustion usually caused by not enough oxygen. In your home, appliances that consume natural gas, charcoal, wood or kerosene are susceptible. Especially if they are not running correctly or have been installed incorrectly.

Vehicle exhaust fumes from nearby garages, as well as fireplaces that aren’t working right could also produce carbon monoxide. CO is dangerous to the body and is lethal at increased levels or with extended exposure.
