What does PASS refer to in fire extinguisher use?

PASS is a mnemonic device that stands for Pull, Aim, Squeeze, and Sweep, providing a simple and effective way to remember the steps for using a fire extinguisher safely and efficiently.

First, "Pull" refers to the action of pulling the pin at the top of the extinguisher to unlock it. This is a crucial first step in ensuring the extinguisher can be used effectively.

Next, "Aim" involves pointing the nozzle at the base of the fire rather than the flames. Hitting the base is important because that's where the fuel source is located, allowing the extinguisher to put the fire out more effectively.

Third, "Squeeze" means to squeeze the handle in order to release the extinguishing agent. This step is necessary to initiate the flow of the material that will help suppress the fire.

Finally, "Sweep" directs the user to sweep the nozzle from side to side at the base of the fire. This technique helps to cover the area of the fire, ensuring that the flames are properly addressed.

This systematic approach is designed to maximize the effectiveness and safety of using a fire extinguisher, making it critical for individuals to be familiar with these steps in emergency situations.
