What does the 'P' in the acronym PASS stand for when using a fire extinguisher?

The 'P' in the acronym PASS stands for "Pull the pin." This is the first step in using a fire extinguisher safely and effectively. Pulling the pin breaks the tamper seal and allows the extinguisher to be activated. It’s essential to hold the extinguisher upright while doing this to ensure it is ready for use.

Understanding this process is crucial for effective fire response; if the pin is not pulled, the extinguisher cannot discharge, rendering it ineffective in controlling the fire. Familiarity with this step, along with the subsequent actions outlined in the PASS acronym—aiming the nozzle, squeezing the handle, and sweeping from side to side—ensures that individuals are adequately prepared to respond to a fire emergency.
