What does the acronym PASS stand for in fire extinguisher usage?

The acronym PASS is a crucial mnemonic that guides individuals on how to effectively use a fire extinguisher in an emergency. The correct answer outlines a sequential process: Pull the pin, Aim the nozzle at the base of the fire, Squeeze the handle, and Sweep the extinguisher from side to side.

Understanding each step is key. Pulling the pin breaks the tamper seal, allowing the extinguisher to operate. Aiming the nozzle at the base of the fire is essential because you need to extinguish the fuel that is burning, not just the flames. Squeezing the handle releases the extinguisher's contents, and sweeping the nozzle from side to side helps cover the area of the fire effectively, ensuring that the fire is extinguished rather than just pushed around.

This methodical approach maximizes the chances of successfully extinguishing a fire and minimizing hazards, which is why it is widely taught in fire safety training programs.
