Tech specs Dry chemical powder Demsa ABC 75

  1. General Features
    Demsa ABC 75 is an efficient ABC type dry chemical extinguishing powder. It is based on mono-ammonium phosphate, the best known and effective multipurpose extinguishing agent. The active ingredient is mixed with silicone additives to improve their fluency and makes it resistant to extreme weather conditions. Demsa ABC 75 is foam agent compatible.
  2. Applications
    Demsa ABC 75 is a multipurpose fire extinguisher powder. It is used in:
    Class A fires: Fires originated by solid combustibles such as wood, paper, fabric, plastic, and most kinds of trash.
    Class B (US std.) – Class B/C (EEC std.) fires:  Fires whose fuel is flammable or combustible liquid or gas
    Class C (US std.) – Class E (EEC std.) fires:  Fires involving potentially energized electrical equipment.
    Demsa ABC 75 is not appropriate for extinguishing metal fires.
    It may be used in both, hand portable and wheeled extinguishers, vehicles and fixed systems. The use of nitrogen as propellant is advisable. Compressed air, or carbon dioxide may also be used.
