What is Carbon Monoxide?

Carbon monoxide (CO) is a colorless, odorless, and tasteless gas produced by burning fuels such as gasoline, wood, propane, and charcoal. According to the Mayo Clinic, CO can be deadly. Appliances and engines that are not properly vented can cause CO to build up to dangerous levels, and the risk is heightened in tightly enclosed spaces.
