DCP Fire Extinguisher

DCP Fire Extinguisher is standing for Dry Chemicals Powder Fire Extinguisher. DCP Fire Extinguishers in Pakistan are the most widely used of all types of extinguishers.

The main base chemicals used in DCP extinguishers are sodium bicarbonate and potassium bicarbonate. DCP extinguishers put out the fire by coating the fuel surface with chemical powder.
This separates the fuel from the oxygen in the air and prevents vapor formation. The powder also interrupts the chemical chain reaction of fire.
The disadvantage is that it leaves a residue, particularly making it difficult to clean up in case of sensitive equipment.

Special Dry Powder Extinguisher

Special extinguishing agents are used for extinguishing
metallic fires.
Dry powders extinguish the fire by forming a crust on
metal surface excluding air and also absorbs heat from
the metal surface.
E.g., Blended sodium chloride-based dry powder,
ternary eutectic chloride(TEC) powder, graphite etc.

Classes of Fire DCP can Extinguish:

DCP fire extinguishers are very reliable for extinguishing the following classes of fires:

  • CLASS A (ORDINARY COMBUSTIBLES)
  • CLASS B (FLAMMABLE LIQUIDS, GREASES, OR GASES)
  • CLASS C (COMBUSTIBLE GASSES)
  • CLASS E (ENERGIZED ELECTRICAL EQUIPMENT)
