ISS Dry Powder system

Dry powder extinguishing system:

Extinguishing powder mainly consists of non-toxic, inorganic salts treated with hydrophobic and flow promoting additives. It is a highly effective and rapid extinguishing agent. The sudden extinguishing effect is obtained from the suffocating and so called anticataly effect a chemical interruption of the combustion process. Powder extinguishing systems are therefore especially recommended where sudden extinguishing is required,e.g. with liquid and gas fires.
