What does the P.A.S.S method refer to in the use of fire extinguishers?

The P.A.S.S method is a crucial procedure for effectively using a fire extinguisher. The correct sequence is Pull, Aim, Squeeze, and Sweep.

Firstly, "Pull" refers to pulling the safety pin from the handle of the extinguisher, which allows the device to function. Next, "Aim" involves directing the nozzle at the base of the fire, targeting the fuel source rather than the flames; this is critical because extinguishing the fuel is what will effectively put the fire out. The third step, "Squeeze," means to press the handle to release the extinguishing agent, which helps to combat the flames. Finally, "Sweep" entails moving the nozzle side to side at the base of the fire, ensuring a thorough application of the extinguishing agent across the affected area.

Understandably, the other options do not accurately represent the standard P.A.S.S method. They substitute or mix up the steps, thus failing to convey the correct process needed to effectively extinguish a fire. Knowing the proper P.A.S.S method is essential for safety and effective fire response in emergency situations.
