What does the acronym PASS stand for in the context of using a fire extinguisher?

The acronym PASS stands for Pull, Aim, Squeeze, Sweep, which is a widely recognized method for using a fire extinguisher effectively. The first step, 'Pull,' refers to pulling the pin on the extinguisher to unlock it and allow it to operate. Secondly, 'Aim' means pointing the nozzle at the base of the fire rather than at the flames themselves, as this is where the fuel source is located. The next step, 'Squeeze,' involves squeezing the handle to release the extinguishing agent. Finally, 'Sweep' directs the nozzle back and forth at the base of the fire until it is completely extinguished. Understanding this sequence helps to ensure the extinguisher is used safely and effectively in an emergency situation.
