What does the acronym PASS stand for in fire safety?

The acronym PASS in fire safety specifically stands for Pull, Aim, Squeeze, and Sweep. This acronym is essential for the proper use of a fire extinguisher. It serves as a mnemonic to help individuals remember the correct steps to take when attempting to extinguish a fire.

When one hears "Pull," it refers to pulling the pin at the top of the fire extinguisher, which unlocks the mechanism and enables operation. Next, "Aim" indicates directing the nozzle at the base of the fire, as targeting the flames directly may be ineffective. The term "Squeeze" pertains to squeezing the handle or lever, which releases the extinguishing agent. Lastly, "Sweep" describes the action of sweeping the nozzle from side to side at the base of the fire until it is completely extinguished.

This method is critical because using a fire extinguisher correctly can prevent small fires from escalating into dangerous situations. Misunderstanding or misapplying these steps can lead to ineffective fire suppression and increased danger. Thus, knowing and correctly using the PASS procedure is crucial for safety in emergency situations involving fire.
