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

The acronym PASS stands for Pull, Aim, Squeeze, and Sweep, and it serves as a critical guideline for effectively using a fire extinguisher. Each component of the acronym represents a vital step in the process of operating a fire extinguisher safely and efficiently.

• Pull refers to the need to pull the pin at the top of the extinguisher, which unlocks the mechanism and allows for operation.

• Aim involves pointing the nozzle at the base of the fire, where the fuel source is located, ensuring that the extinguishing agent can effectively reach and suppress the flames.

• Squeeze means to squeeze the handle or lever to release the extinguishing agent. This step is essential to control the discharge of the agent efficiently.

• Sweep suggests moving the nozzle from side to side at the base of the fire, which helps to cover the area and effectively extinguish the flames.

Understanding and following the PASS technique is crucial for anyone who may need to use a fire extinguisher because it maximizes the chances of successfully putting out a fire while minimizing risk to oneself and others.
