Not classified as flammable. This product can react vigorously with acids to liberate hydrogen, which can form explosive mixtures with air. Under special conditions nickel can react with carbon monoxide in reducing atmospheres to form Nickel Carbonyl, Ni(CO) 4 , a toxic gas. Metal powders when heated in reducing atmospheres may become pyrophoric.
