Carbon Monoxide Gas CO

Carbon monoxide is a colorless, odorless, tasteless and non-irritating toxic gas at normal temperature and pressure. It is flammable in air and emits a blue flame when burning. Carbon monoxide slowly enters the human body without any stimulation and causes poisoning and death, and is the main cause of gas poisoning.
