Carbon monoxide (CO) is a clear, odorless and tasteless gas. It’s created by incomplete fuel combustion frequently caused by insufficient oxygen. In your house, appliances that rely on natural gas, charcoal, wood or kerosene are vulnerable. Especially if they are not running accurately or have been installed incorrectly.
Vehicle exhaust fumes from attached garages, as well as malfunctioning fireplaces could also create carbon monoxide. CO is dangerous to the body and is fatal at heightened levels or with extended exposure.
