What is the correct method for using a fire extinguisher?

The effective method for using a fire extinguisher is summarized by the acronym "PASS," which stands for Pull, Aim, Squeeze, and Sweep. Initially, when confronted with a fire, the first step is to pull the pin at the top of the extinguisher, which unlocks the operating lever and allows you to use the device.

Next, you aim the nozzle at the base of the fire, ensuring that you are targeting the source of the flames rather than the flames themselves. This is crucial because extinguishing agents need to eliminate the combustible material fueling the fire.

The third step is to squeeze the lever slowly to release the extinguishing agent. This action should be steady and controlled to efficiently disperse the agent over the fire. Finally, you sweep the nozzle from side to side, covering the area of the fire until it is fully extinguished. This sweeping motion helps to thoroughly coat the fire with the extinguishing material, enhancing the likelihood of successful suppression.

Other provided methods contain variations in wording or sequence that do not accurately represent the correct procedure, highlighting the importance of remembering the established "PASS" technique to effectively use a fire extinguisher in an emergency situation.
