What does the 'P' in the PASS acronym for fire extinguisher use stand for?

The 'P' in the PASS acronym, which is a widely recognized method for using a fire extinguisher, stands for "Pull the pin." This step is crucial as it enables the user to activate the extinguisher. Pulling the pin typically releases a safety mechanism that allows the extinguisher to be discharged. This initial action is essential because, without pulling the pin, the extinguisher cannot function properly even if other steps are followed.

Understanding the PASS acronym is important because it provides a systematic approach to fire extinguisher use, which can be critical in emergency situations. The subsequent steps in PASS instruct the user to aim the extinguisher at the base of the fire, squeeze the handle, and sweep the nozzle side to side. Each step builds on the previous one, but pulling the pin is the foundational action that enables the rest of the procedure.
