What does the acronym PASS stand for when operating a fire extinguisher?

The acronym PASS stands for Pull, Aim, Squeeze, Sweep, and it is a crucial mnemonic used to remember the proper steps for operating a fire extinguisher effectively.

First, "Pull" refers to removing the safety pin or ring that secures the extinguisher. This action ensures that it is ready to discharge. Next, "Aim" involves pointing the nozzle or outlet of the extinguisher towards the base of the fire, which is important because targeting the flames directly may not extinguish the fire effectively. "Squeeze" instructs the user to squeeze the handle or lever of the extinguisher to discharge the extinguishing agent. Finally, "Sweep" entails moving the extinguisher nozzle from side to side, covering the area of the fire, which helps to ensure that the extinguishing agent reaches the fire thoroughly.

This systematic approach helps users efficiently operate a fire extinguisher during an emergency, maximizing their chances of successfully extinguishing small fires before they escalate. Understanding and remembering these steps is essential for safety training and fire prevention initiatives in various environments.
