Carbon Monoxide

Carbon monoxide (CO) is a dangerous gas that is invisible, has no smell, and can be deadly. It is created when carbon-based fuels like natural gas, propane, oil, wood, or coal are burned, but there isn’t enough oxygen for the fuel to burn completely. This is often caused by a malfunction in heating equipment, poor ventilation, or an improper air-to-fuel ratio. Because it is undetectable without special devices, carbon monoxide can build up without people noticing, making it vital to have carbon monoxide detectors in homes and buildings to ensure safety.
