What does the 'P' in PASS stand for in fire extinguisher operation?

• A. Pin
• B. Pull
• C. Push
• D. Pour

Answer: (B)

In fire extinguisher use, PASS is a quick, four-step sequence to deploy the extinguisher safely in an emergency. The first step is to pull the pin, which removes the safety seal and unlocks the operating lever. The pin is there to prevent accidental discharge during handling, so pulling it is the necessary action before you can proceed to aim, squeeze, and sweep. The other options don’t fit: you don’t push the pin to start or pour anything from the extinguisher—what you do is pull to unlock, then aim at the base, squeeze the handle, and sweep the nozzle across the fire.
