The PASS technique acronym stands for the steps used when operating a fire extinguisher. Which option lists the steps correctly?

• A. Push, Aim, Squeeze, Sweep
• B. Pull, Aim, Squeeze, Sweep
• C. Pull, Aim, Release, Sweep
• D. Pull, Target, Squeeze, Sweep

Answer: (B)

Using a fire extinguisher safely hinges on the PASS sequence. Start by pulling the pin to break the tamper seal and allow the extinguisher to discharge. Next, aim the nozzle at the base of the fire—the part where the fuel is burning—not at the flames themselves—so you attack the source of the fire. Then squeeze the handle to release the extinguishing agent. Finally, sweep the nozzle from side to side at the base of the fire to cover the area and push the fire back and, if possible, extinguish it completely. The other options fail because they describe actions that don’t release the extinguisher properly (pushing or releasing) or they indicate aiming at the wrong target (the flames or a point not at the base).
