What is the proper sequence to operate a fire extinguisher?

• A. Pull the pin, aim low, squeeze the lever, sweep side to side
• B. Pull the pin, aim high, squeeze the lever, sweep side to side
• C. Pull the handle, aim low, squeeze the lever, sweep side to side
• D. Pull the pin, aim low, press the lever, sweep side to side

Answer: (A)

Using a fire extinguisher follows the PASS method: Pull, Aim, Squeeze, Sweep. Start by pulling the pin to break the tamper seal and unlock the device. Then aim low at the base of the fire so you target the fuel source rather than the flames. Next, squeeze the lever to release the extinguishing agent. Finally, sweep the nozzle side to side at the base of the fire to blanket the area and prevent reignition. The correct sequence is important because missing the base or releasing the agent in the wrong order reduces effectiveness and can allow the fire to keep burning.
