Carbon monoxide detectors are designed to alert occupants to the presence of carbon monoxide gas, which is colorless and odorless. This gas can be produced by fuel-burning appliances and equipment.
Because carbon monoxide cannot be detected by human senses, electronic monitoring devices are used as a safety measure. Detectors provide an added layer of awareness rather than preventing gas production.
Understanding their purpose helps explain why these devices are commonly recommended in residential settings.
