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

The acronym PASS stands for Pull, Aim, Squeeze, Sweep, which is a critical methodology for using a fire extinguisher effectively. Understanding this sequence helps ensure that the extinguishing agent is deployed safely and effectively to combat a fire.

Pull refers to the action of removing the safety pin from the extinguisher's handle. This is a necessary first step as it enables the extinguisher to operate. Aim instructs you to direct the nozzle or hose at the base of the fire, which is essential because aiming at the flames is ineffective. Squeeze involves pressing the handle of the extinguisher to release the extinguishing agent; this requires sufficient pressure to ensure that the agent flows out appropriately. Lastly, Sweep means moving the nozzle from side to side at the base of the fire, which helps to cover the area where the fuel is burning and effectively eliminate the flames.

Mastering the PASS technique is crucial for anyone who might need to use a fire extinguisher, as it provides a structured approach to responding to a fire emergency safely and effectively. This training emphasizes not just how to use the extinguisher, but also improves the likelihood of successfully extinguishing the fire before it spreads.
