Carbon dioxide fire extinguishers - the most suitable for fighting fires occurring in electrical and electronic equipment, carbon dioxide has no corrosive effect, does not cause damage to the equipment. Dry powder fire extinguishers - it combines the strengths of carbon tetrachloride and carbon dioxide, suitable for fighting electrical fires, extinguishing speed.
Note that you can never use acid or alkali or foam fire extinguishers, because of its fire-fighting liquid conductive, hand-held fire extinguishers will be electrocuted. This liquid will strongly corrode electrical equipment, and it is not easy to remove afterwards. Dry powder fire extinguishers are filled with dry powder fire extinguishing agent. Dry powder fire extinguishing agent is used to extinguish the dry and easy to flow micro-fine powder, by the fire-fighting effectiveness of inorganic salts and a small number of additives by drying, crushing, mixing and become micro-fine solid powder composition. The use of compressed carbon dioxide to blow out the dry powder to extinguish the fire.
