What does the acronym PASS stand for in relation to using a fire extinguisher?

The acronym PASS is a fundamental guideline for using a fire extinguisher effectively and safely. It stands for Pull, Aim, Squeeze, and Sweep.

Pull refers to the action of pulling the pin on the extinguisher's handle. This is an important first step because it allows you to use the extinguisher and ensures that it is ready for operation.

Aim involves directing the nozzle of the extinguisher toward the base of the fire. This is crucial, as aiming at the flames rather than the base will not effectively smother the fire.

Squeeze means to squeeze the handle to release the extinguishing agent. This step is where the user actively engages with the extinguisher to deliver the necessary material to combat the fire.

Finally, Sweep is the motion of moving the nozzle from side to side while aiming at the base of the fire, which helps to cover a larger area and effectively extinguish the flames.

Understanding and practicing the PASS method is essential for anyone trained to respond to a fire, ensuring that they can act quickly and efficiently in an emergency situation.
