Carbon monoxide (CO), commonly referred to as carbon monoxide, is an invisible, odorless and tasteless gas that is toxic to humans and animals. It is often referred to as the "silent killer" because it cannot be smelled, tasted or seen. The initial symptoms of CO poisoning are fatigue and headache, similar to the common cold or flu, but prolonged exposure or high concentrations lead to disorientation, fainting and loss of consciousness and may lead to death within a few hours.
Carbon monoxide is produced during incomplete combustion of fuels and combustible materials, e.g. coal, wood, heating oil, kerosene, gasoline, natural gas, propane, butane, etc.
