How does one effectively utilize a fire extinguisher according to the PASS technique?

The PASS technique for effectively using a fire extinguisher is centered on a specific sequence of actions that ensure safety and effectiveness. The correct sequence involves pulling the pin, aiming the nozzle at the base of the fire, squeezing the handle to release the extinguishing agent, and then sweeping the nozzle from side to side at the base of the fire.

Starting with "Pull," this action is crucial because it allows you to unlock the extinguisher and prepare it for use. The next step, "Aim," is vital; focusing on the base of the fire is essential because this is where the combustion is occurring, and extinguishing agents need to reach this area to be most effective. The "Squeeze" action releases the extinguishing agent, providing the necessary flow to combat the fire. Finally, "Sweep" entails moving the nozzle from side to side, ensuring that the extinguishing agent covers the fire completely and preventing re-ignition by ensuring consistent application.

While the other options may use different terminology, they do not reflect the correct sequence or the essential actions involved in using a fire extinguisher safely and effectively.
