What is carbon monoxide?

Carbon monoxide (CO) is a clear, odorless and tasteless gas. It’s made by partial fuel combustion usually caused by not enough oxygen. In your house, appliances that need natural gas, charcoal, wood or kerosene are vulnerable. Especially if they are not working correctly or have been installed improperly.

Vehicle exhaust fumes from nearby garages, as well as malfunctioning fireplaces could also produce carbon monoxide. CO is toxic to the body and is deadly at heightened levels or with extended exposure.
