What are the four steps of the PASS technique for extinguishers?

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

Answer: (D)

PASS is the four-step method for using a portable fire extinguisher safely and effectively. You start by pulling the pin to break the tamper seal and enable discharge. Then you aim the nozzle at the base of the fire to target the fuel source rather than the flames. Next you squeeze the handle to release the extinguishing agent in a controlled stream. Finally you sweep the nozzle from side to side at the base of the fire to blanket the area and prevent re-ignition. This sequence ensures the safety mechanism is disengaged, directs the agent to where it’s needed, and provides thorough coverage. Using a push rather than pull would fail to activate the extinguisher, and tilting the nozzle while aiming wastes effectiveness by not targeting the fuel source at the base.
