What does PASS stand for when using a fire extinguisher?

• A. Pull, Aim, Squeeze, Sweep
• B. Pull, Assess, Squeeze, Sweep
• C. Pull, Shake, Squeeze, Sweep
• D. Pull, Aim, Squeeze, Shock

Answer: (B)

The main idea tested is how to use a fire extinguisher quickly and effectively with the PASS method: Pull, Aim, Squeeze, Sweep. Start by pulling the pin to break the tamper seal, which allows the extinguisher to discharge. Then aim the nozzle at the base of the fire, not at the flames, so you target the fuel source. Next, squeeze the handle to release the extinguishing agent. Finally, sweep the nozzle from side to side at the base of the fire to blanket the area and smother the flames. This sequence ensures the agent reaches the fuel and has a better chance of stopping the fire. The other words shown in the options aren’t part of the standard procedure—Assess, Shake, or Shock don’t correspond to the required steps and could lead to delays or ineffective action.
