Basic Firefighter Written Practice Exam

Which step is the last in the PASS method for using an extinguisher?

1. Squeeze the handle

2. Aim the nozzle

3. Pull the pin

4. Sweep back and forth

The correct answer is: Sweep back and forth

The last step in the PASS method for using a fire extinguisher is to sweep back and forth at the base of the fire. This action is crucial because it helps to cover the area of the fire effectively, ensuring that the extinguishing agent is applied thoroughly and can adequately suppress the flames. Sweeping back and forth allows the firefighter to address the fire from its base, where the fuel source is located, rather than just trying to put out flames that may be above the fuel. This method increases the likelihood of extinguishing the fire completely and minimizes the risk of flare-ups. In contrast, pulling the pin is the necessary first step that allows the extinguisher to be activated, squeezing the handle releases the extinguishing agent, and aiming the nozzle prepares the user to direct the agent at the fire. Each of these steps is important, but the sweeping motion is the final action that can effectively extinguish the fire.
