What fire extinguisher is used for magnesium alloy fire?
Under no circumstances shall water or any other non D fire extinguishers be used to extinguish the fire caused by magnesium. Water, other liquids, carbon dioxide, foam, etc., react with the burning magnesium and strengthen the fire, not the fire.
Iron debris: no other good fire extinguishing materials are available, the main role is to reduce the temperature to the burning point of Mg, rather than suffocate the fire.
Small fire area with dry sand and covering agents suffocate.
Class D fire extinguisher: the material is usually using sodium chloride or a base powder by graphite powder passivation, its principle is through the exclusion of oxygen to smother the fire; because of the late origin of magnesium alloy die casting in our country, the class D extinguishers only foreign manufacturers have the production, so the purchase must look for the security products quality certification and insurance companies, to ensure the safety of practical and effective.
