What does the acronym "PASS" stand for in fire extinguisher use?

The acronym "PASS" in the context of fire extinguisher use stands for "Pull, Aim, Squeeze, Sweep." This method is essential for effectively operating a fire extinguisher in an emergency situation.

The first step, "Pull," refers to removing the safety pin from the handle of the fire extinguisher. This action prevents accidental discharge and allows the extinguisher to be used. Next, "Aim" indicates that the user should point the nozzle at the base of the fire, which is crucial because extinguishing a fire from the top will not effectively eliminate the flames.

The third step, "Squeeze," instructs the user to squeeze the handle to release the extinguishing agent. This action allows the agent to shoot out at high pressure, maximizing its effectiveness. Finally, "Sweep" instructs the user to move the nozzle side to side at the base of the fire, ensuring that the extinguishing agent covers a broad area and reaches the fuel source.

This systematic approach is vital for safely and efficiently combating small fires, highlighting the importance of following these steps in a real-world scenario. Understanding and using the PASS technique can significantly improve safety outcomes in fire-related emergencies.
