Dry Powder Extinguishers
Dry powder extinguishers are extremely versatile, and can be used on fires in Class A, B or C – involving flammable liquids, electrical fires, or burning materials like wood or paper. However, if the fire could involve computers, choose residue-free CO2 Fire Extinguishers.
Specialist applications require particular types of dry powder fire extinguishers, such as a Monnex fire extinguisher for fuel storage or motorsport, or L2 fire extinguishers for burning metal fires. Popular for a car extinguisher is the 600g aerosol extinguisher or the 1kg dry powder extinguisher.

Dry Powder fire extinguishers work by chemical reaction with the fire causing the particles to expand , chemically inhibiting combustion and expelling the oxygen necessary for combustion thereby "knocking down" the flames. Dry Powder fire extinguishers are colour coded with a blue label.
Using a dry powder fire extinguisher:
- Pull out the retaining pin (this will break the plastic "pull tight" security seal) and squeeze the grip to discharge the extinguisher.
- On fires involving either liquids in containers direct the nozzle towards the near edge of the fire.
- With the rapid sweeping motion drive the fire towards the far edge until all the flames are extinguished.
- On fires involving flowing liquids, direct the nozzle at the base of the flames and sweep upwards.
- On fires in electrical equipment, switch off the power supply if safe to do so and then direct the nozzle straight at the fire.
- Where the fire is in an enclosed compartment, direct into any opening with the object of penetrating the interior.
- When the fire appears to be extinguished release the grip to shut off the discharge and allow the atmosphere to clear. If any flame is then still visible, discharge again.
