Carbon monoxide (CO) is a colorless, odorless and tasteless gas. It’s created by partial fuel combustion usually caused by a lack of oxygen. In your residence, appliances that use natural gas, charcoal, wood or kerosene are vulnerable. Especially if they are not working properly or have been installed incorrectly.
Vehicle exhaust fumes from attached garages, as well as fireplaces that aren’t working right can also create carbon monoxide. CO is toxic to the body and is lethal at increased levels or with prolonged exposure.
