How to use Wet Chemical Fire Extinguishers

  1. Before attempting to fight a fire with a fire extinguisher it is important to firstly check that the extinguisher is fully charged (Fig. 1) and that the safety pin has not been bent (Fig. 2).
  2. Turn off the heat source if it is safe to do so.
  3. Ensure you remain a safe distance from the fire and remove the safety pin (Fig. 3) this will break the tamper seal.
  4. Hold the lance at arm's length, well above the fire with its nozzle at least 1 metre away from the fire.
  5. Squeeze the lever slowly to begin discharging the extinguisher.
  6. Apply the fine spray in slow circular movements, this allows the wet chemical agent to fall gently onto the surface of the fire and helps to prevent hot oils splashing on to the user.
  7. Discharge the entire contents of the extinguisher to ensure that all of the fire has been extinguished, the wet chemical formula helps to prevent re-ignition.
