Steps Of How To Use A Fire Extinguisher

Knowing the steps of how to use a fire extinguisher before a fire occurs could be the difference between successfully extinguishing the fire or the fire getting out of control.

Fire extinguishers should only be used in the following circumstances:

  • Once evacuation has been initiated.
  • When the fire service has been called.
  • When it is safe to do so considering the size and location of the fire.
  • Access to the fire is unrestricted, and a safe retreat is possible at all times.

Remember life is more important than property, don’t put yourself or others at risk.

What Does Pass Mean When Using A Fire Extinguisher?

  1. Pull the pin at the top of the extinguisher.
  2. Aim the nozzle towards the base of the fire.
  3. Squeeze the handle to discharge the extinguisher.
  4. Sweep the nozzle from side to side aiming at the base of the fire.

Remembering how to use a fire extinguisher, remember the PASS-word
