What does the acronym PASS stand for in using a fire extinguisher?

The acronym PASS stands for Pull, Aim, Squeeze, Sweep and is a crucial mnemonic for the correct operation of a fire extinguisher. Understanding this sequence is essential for effectively using an extinguisher to combat a fire.

• The first step, "Pull," refers to removing the safety pin from the extinguisher's handle. This is a necessary action to enable the extinguisher to be activated.

• The second step, "Aim," involves pointing the nozzle at the base of the fire. Aiming at the source of the flames is critical for effectively extinguishing the fire rather than just dispersing the flames.

• The third step, "Squeeze," requires you to compress the handle to release the extinguishing agent. This action is necessary to actually dispel the foam or powder that will put out the fire.

• Finally, "Sweep" means moving the nozzle from side to side at the base of the fire to ensure that the extinguishing agent covers the area thoroughly and effectively smothers the flames.

This systematic approach helps ensure that the user operates the fire extinguisher correctly and responds effectively in an emergency.
