How Do I Use Air Water Fire Extinguisher?

Water fire extinguishers are suitable for use on class A fires involving solid combustible materials such as wood, paper, and textiles. Each fire should be tackled differently depending on how the fire is spreading.

Before attempting to tackle a fire with an extinguisher you need to make sure that the extinguisher is safe to use.

  1. Check that the extinguisher is fully charged by ensuring the pressure gauge is in the green area and that the safety pin is not bent
  2. Quickly check that there is no live electrical equipment in the area
  3. Ensure you remain a safe distance from the fire and remove the safety pin this will break the tamper seal
  4. Where to aim the fire extinguisher hose:
  5. Fires spreading horizontally: Aim the hose at the base of the fire, moving the jet across the area of the fire
  6. Fire spreading vertically: Aim the hose at the base of the fire, slowly moving the jet upwards following the direction of the fire
  7. Squeeze the lever slowly to begin discharging the extinguisher, as the fire starts to diminish carefully move closer to it
  8. Ensure all the fire has been extinguished, try to focus on any hot spots that may re-ignite.

                                            

Air Water Fire Extinguisher Maintenance

It is routine for fire extinguishers to be checked every six months by a service team as required per regulations. However, we recommend once a month to ensure the following:

  • The extinguisher is not blocked by equipment, coats or other objects that interfere with access in an emergency.
  • The pressure is at the recommended level, this means the needle should be in the green zone- not too high and not too low.
  • The nozzle or other parts are not obstructed
  • The pin and tamper seal is intact
  • There are no dents, leaks, rust, chemical deposits and other signs of abuse/wear. Wipe off any corrosive chemicals, oil, gunk etc. that may have landed on the extinguisher.
  • Fire extinguishers should be pressure tested (a process called hydrostatic testing) after a number of years to ensure that the cylinder is safe to use. We provide our partner, majestic fire with pressure testing and maintenance services.
