What does PASS stand for in fire safety?


    What is the PASS fire extinguisher method?

    PASS stands for Pull, Aim, Squeeze, Sweep and refers to the correct and safest way to extinguish a fire using a fire extinguisher. It is a useful way to remember each step when it comes to extinguishing a fire.

    • PULL

      If you need to use an extinguisher, the first thing you need to do is pull out the safety pin, enabling you to push the handle down.

    • AIM

      After you have pulled the pin out, you need to aim the nozzle at the base of the fire. If the extinguisher is aimed too high, the source of the fire is more likely to continue to burn.


      Next, you should squeeze the handle to activate the fire extinguisher and discharge its contents. It is vital to use the correct type of fire extinguisher for the class of fire that is burning.

    • SWEEP

      For the most effective results, when squeezing sweep the nozzle from side to side, covering the base of the fire and fully extinguishing the flames

    CO2 Fire Extinguishers

    It is worth noting that CO2 extinguishers are different to other types of fire extinguishers, and it is important you are aware of the difference when using one. Due to the nature of a CO2 fire extinguisher's contents, the nozzle must not be touched during discharge, as the extremely cold temperatures which result can burn the user's hand.
