What method is used to operate a fire extinguisher effectively?

The method used to operate a fire extinguisher effectively is known as PASS, which stands for Pull, Aim, Squeeze, and Sweep. This acronym provides a straightforward, systematic approach to using a fire extinguisher properly.

First, you pull the pin to break the seal and ensure that the extinguisher is armed. Next, you aim the nozzle at the base of the fire, where the fuel source is located, rather than at the flames themselves, as this is essential for effectively suppressing the fire. Once aimed correctly, you squeeze the handle to release the extinguishing agent. Finally, you sweep the nozzle from side to side to cover the area of the fire, ensuring you adequately extinguish it.

Using the PASS method not only enhances the effectiveness of the fire extinguisher but also promotes safety by providing a clear sequence of steps for operating it amidst the stress of an emergency situation. Understanding this method is crucial for anyone who may need to use a fire extinguisher.
