What does the acronym PASS stand for when using a fire extinguisher?

The acronym PASS stands for Pull, Aim, Squeeze, Sweep, which is a systematic approach to using a fire extinguisher effectively.

• The first step, "Pull," refers to removing the pin or locking mechanism from the handle of the extinguisher. This step is crucial as it engages the extinguisher, allowing it to be operational.

• The second step, "Aim," involves directing the nozzle at the base of the fire. This is important because targeting the base ensures that the extinguishing agent is effectively interrupting the fuel supply to the flames.

• The third step, "Squeeze," indicates that the operator should squeeze the handle to release the extinguishing agent. This action discharges the agent needed to combat the fire.

• Lastly, "Sweep" means moving the extinguisher nozzle from side to side at the base of the fire, ensuring coverage over the flames until they are fully extinguished.

This method enhances safety and effectiveness while using a fire extinguisher, making it a critical concept for firefighters and the general public in fire emergencies.
