Dry Powder fire extinguishers are the most versatile of all fire extinguishers and can be used on Class A, B & C fires and fires involving electrical equipment. For sensitive electrical equipment such as computers it is advisable to use a CO2 extinguisher which leaves no residue.

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:

1. Pull out the retaining pin (this will break the plastic "pull tight" security seal) and squeeze the grip to discharge the extinguisher.
2. On fires involving either liquids in containers direct the nozzle towards the near edge of the fire.
3. With the rapid sweeping motion drive the fire towards the far edge until all the flames are extinguished.
4. On fires involving flowing liquids, direct the nozzle at the base of the flames and sweep upwards.
5. On fires in electrical equipment, switch off the power supply if safe to do so and then direct the nozzle straight at the fire.
6. Where the fire is in an enclosed compartment, direct into any opening with the object of penetrating the interior.
7. 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.
   Note the 1Kg shrouded head extinguisher is press button operated
