What is a recommended procedure for using a fire extinguisher?

The recommended procedure for using a fire extinguisher is to "Pull, Aim, Squeeze, Sweep." This method is commonly referred to by the acronym PASS, which serves as an easy way to remember the sequence of actions needed to effectively operate a fire extinguisher.

First, pulling the pin is crucial because it unlocks the mechanism and allows you to use the extinguisher. Then, aiming the nozzle at the base of the fire is essential since the flames need to be smothered at their source for maximum effectiveness. Squeezing the handle releases the agent contained within the extinguisher, which is designed to quell the flames. Finally, sweeping the nozzle from side to side helps to cover the area of the fire evenly and ensures that the extinguishing agent is applied effectively.

This method emphasizes safety and efficiency in dealing with fire emergencies, focusing on targeting the flames directly while maintaining control of the extinguisher's operation. Knowledge of the PASS technique is critical for ensuring quick and effective action during a fire situation, which is why this option is the correct answer.
