What does the acronym PASS stand for in the context of using a fire extinguisher?

In the context of using a fire extinguisher, the acronym PASS stands for "Pull, Aim, Squeeze, Sweep." This mnemonic helps individuals remember the proper sequence for operating an extinguisher effectively and safely.

The first step, "Pull," refers to pulling the pin at the top of the extinguisher, which allows you to begin using the device. The second step, "Aim," is about directing the nozzle of the extinguisher towards the base of the fire, as this is where the flame originates and where the agent can be most effective. The third action, "Squeeze," involves squeezing the handle to release the fire-suppressing agent contained within the extinguisher. Lastly, "Sweep" instructs users to sweep the nozzle from side to side at the base of the fire until it is completely extinguished.

This systematic approach is crucial for ensuring safety and effectiveness when responding to a fire. The other choices provide different phrases that do not correspond to the standard method for using a fire extinguisher, making them less effective for this specific context.
