a) Working of DCP?

     DCP extinguishers put out fire by coating the fuel with a thin layer of dust, interrupting the chemical reaction & cutting off the oxygen supply.

b) Maintenance of DCP

• Check the hose outlet and clean
• Check the safety pin in position
• Check labels are in place
• Check the pressure needle in the green zone.
• Check for caking of powder.
• It must be inverted once a month to avoid choking.
• Weight a cylinder

• Do not use in a fully enclosed space or a poorly ventilated area.
• Working pressure is high (55 bar), so hold it tightly.
• Due to higher pressure, it discharges very quickly, so aim directly at the fire.
• When CO₂ turns from liquid to gas, the temperature is extremely low; Do not hold the horn until it is a frost-free horn.
• Switch off the power supply of the equipment in a fire.
• It makes a very strong discharge noise, which is normal.
