Carbon monoxide detectors are essential safety devices that detect the presence of carbon monoxide (CO) in the air. Carbon monoxide is an odorless, colorless, and tasteless gas that is produced by burning fuel such as natural gas, wood, oil, and coal. It is a deadly poison that can cause serious health problems and even death. Carbon monoxide detectors are designed to alert you when dangerous levels of carbon monoxide are present in your home or business. They are an important part of any home or business safety plan and should be installed in all areas where fuel-burning appliances are used.
