Carbon monoxide (CO) is an odorless, colorless and tasteless toxic gas. It is a by-product of the incomplete combustion of fossil fuels such as gas, kerosene, oil, wood and coal. Common sources of carbon monoxide in the home include heating systems, ranges and ovens, clothes dryers, water heaters, fireplaces and wood stoves. Indirect sources include powered tools, charcoal grilles and motor vehicles.

Considerations
To minimize CO concerns, the HouseMaster Technical Staff recommends homeowners install (and test regularly) carbon monoxide detectors throughout their homes. Should any CO concerns surface, all fuel-burning and venting provisions should be checked. The potential infiltration of CO gases from attached garages should also be considered as a source of CO.
