What does the acronym PASS stand for in firefighting?

The acronym PASS is a vital safety procedure used in firefighting, particularly when utilizing a fire extinguisher. It stands for Pull, Aim, Squeeze, and Sweep.

Understanding each component helps ensure effective use of the extinguisher. "Pull" refers to pulling the pin on the fire extinguisher, which unlocks the operating lever and allows for use. "Aim" means directing the nozzle at the base of the fire, as this is where the fuel source is located. "Squeeze" indicates that the handle should be squeezed to release the extinguishing agent; this is necessary to create the pressurized discharge of the substance within the extinguisher. Finally, "Sweep" means to sweep the nozzle side to side at the base of the fire to effectively extinguish the flames.

The other options do not represent the standard procedure recognized in firefighting practice. Therefore, understanding PASS is crucial for any firefighter to act safely and effectively in emergency situations.
