Which of the following is a protocol for using a fire extinguisher?

The correct answer is "Pull, Aim, Squeeze, Sweep," which describes the widely accepted protocol for using a fire extinguisher effectively. This method is known as the PASS technique.

1. Pull: First, you pull the safety pin from the handle of the extinguisher. This step allows you to use the extinguisher; without removing the pin, the unit cannot operate.

2. Aim: Next, you aim the nozzle at the base of the fire. Targeting the base rather than the flames is crucial because this is where the fuel is burning, giving you the most effective chance of extinguishing the fire.

3. Squeeze: After aiming, you squeeze the handle to release the extinguishing agent. This action should result in the discharge of the material that will combat the flames.

4. Sweep: Finally, you should sweep the nozzle from side to side at the base of the fire while continuing to discharge the agent until the fire is out. This sweeping motion helps cover the area of the fire and can help ensure that it is fully extinguished.

Understanding and remembering this sequence is key to safely and effectively using a fire extinguisher in emergency situations. Other options do not reflect
