Nickel carbonyl poisoning

Nickel carbonyl is a liquid metal compound formed by the reaction of nickel metal with carbonyl (-CO) under a certain pressure. Nickel car-bonyI poisoning is a systemic disease with damage to the respiratory and nervous systems. Nickel carbonyl is a highly toxic substance. It is estimated that the lethal concentration of human in 30 minutes is about 3000 mg / m3. Nickel carbonyl gas is non-irritating and difficult to detect. In the industry, nickel carbonyl is used for refining high-purity nickel powder, organic synthesis, rubber, petroleum catalyst, nickel spraying, etc. After workers inhale a large amount, acute poisoning can occur.
