What is carbon monoxide?

Carbon monoxide (CO) is an invisible, odorless and tasteless gas. It’s produced by incomplete fuel combustion frequently caused by not enough oxygen. In your house, appliances that rely on natural gas, charcoal, wood or kerosene are susceptible. Especially if they are not working properly or have been installed improperly.

Vehicle exhaust fumes from attached garages, as well as malfunctioning fireplaces can also create carbon monoxide. CO is dangerous to the body and is deadly at high levels or with prolonged exposure.
