What is carbon monoxide?

Carbon monoxide (CO) is a colorless, odorless and tasteless gas. It’s made by incomplete fuel combustion usually caused by a lack of oxygen. In your residence, appliances that rely on natural gas, charcoal, wood or kerosene are at risk. Especially if they are not operating accurately or have been installed wrong.

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