What is carbon monoxide?

Carbon monoxide (CO) is a clear, odorless and tasteless gas. It’s created by insufficient fuel combustion frequently caused by insufficient oxygen. In your house, appliances that consume natural gas, charcoal, wood or kerosene are susceptible. Especially if they are not running properly or have been installed improperly.

Vehicle exhaust fumes from attached garages, as well as malfunctioning fireplaces may also create carbon monoxide. CO is toxic to the body and is fatal at high levels or with long exposure.
