Carbon monoxide is a silent killer because not only can we not see or smell it, we also breathe it in normally with no irritation to our nose and throats. The gas kills when a large amount of it binds to our red blood cells and displaces oxygen. This eventually suffocates our body from an adequate oxygen supply.
