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

The acronym PASS stands for Pull, Aim, Squeeze, Sweep, which is a universally recognized method for using a fire extinguisher effectively.

To use a fire extinguisher correctly, first, you "Pull" the pin on the extinguisher. This pin is designed to prevent accidental discharge and must be removed before operating the extinguisher. Next, you "Aim" the nozzle at the base of the fire, ensuring that you target the source of the flames for maximum effectiveness. After aiming, you "Squeeze" the handle to release the extinguishing agent. Finally, you "Sweep" the nozzle from side to side at the base of the fire until it appears to be out. This sweeping motion helps cover the area with the extinguishing agent to ensure the fire is thoroughly extinguished and does not reignite.

Understanding this procedure not only ensures proper usage but also enhances safety during a fire emergency, which is why recognizing the correct elements of the PASS acronym is crucial for anyone handling fire extinguishers.
