What is the final step in the PASS method for using a fire extinguisher?

The final step in the PASS method, which stands for Pull, Aim, Squeeze, and Sweep, involves sweeping the spray side to side at the base of the fire. This sweeping motion ensures that the extinguishing agent is effectively covering the area of the fire and disrupting the flames. By sweeping, you maximize the contact of the extinguishing agent with the fire, which can help remove its heat and prevent re-ignition. A steady side-to-side motion also helps ensure that all parts of the burning material are addressed, rather than just one spot, increasing the likelihood of successfully extinguishing the fire.

The other options do not represent the final step in the PASS method. Standing at least 20 feet away is a safety precaution that helps to ensure you are at a safe distance when approaching a fire. Squeezing rapidly is not a step in the PASS acronym, as the correct usage involves squeezing the handle to release the extinguishing agent steadily rather than rapidly. Aiming high would not effectively target the base of the fire where extinguishing action is most needed, as fires typically need to be disrupted at their source.
