According to the P.A.S.S. method, what does 'S' mean regarding using a fire extinguisher?

In the context of the P.A.S.S. method for using a fire extinguisher, 'S' stands for "Sweep the nozzle." This step is critical because it instructs the user to aim the nozzle at the base of the fire and sweep it back and forth in a controlled motion. This technique ensures that the extinguishing agent is most effective at smothering the flames and preventing them from re-igniting.

By focusing on the base of the fire, the user targets the fuel source that is actively burning rather than the flames themselves. This understanding of fire behavior is crucial for successfully extinguishing a fire.

The other terms mentioned in the options, while related to fire safety, do not accurately describe the second step of the P.A.S.S. method. The full method outlines a specific sequence of actions: Pull the pin, Aim low, Sweep the nozzle, and Sound the alarm, where 'S' specifically directs the user to aim and sweep for effective fire suppression.
