What does PASS stand for when using a portable fire extinguisher?

• A. Pull, Aim, Squeeze, Sweep
• B. Push, Aim, Squeeze, Sweep
• C. Pull, Alert, Squeeze, Sweep
• D. Pull, Aim, Stop, Sweep

Answer: (A)

PASS is the mnemonic for operating a portable fire extinguisher: Pull, Aim, Squeeze, Sweep. First you pull the pin to unlock the extinguisher, removing the safety seal so it can discharge. Next you aim the nozzle at the base of the fire, targeting where the fuel source is located rather than aiming at the flames. Then you squeeze the handles to release the extinguishing agent. Finally you sweep the nozzle from side to side to blanket the area and push the fire back until it’s out or you must retreat. The other options don’t fit because they change or omit a key step: pushing instead of pulling won’t arm the device, and terms like alert or stop aren’t part of the proper sequence for using the extinguisher.
