What is the correct PASS method sequence for using a fire extinguisher?

• A. Pull safety pin; Aim nozzle at base of flames; Squeeze handle in short 0.5 sec bursts; Sweep nozzle from side to side.
• B. Aim nozzle at base of flames; Pull safety pin; Squeeze handle; Sweep.
• C. Squeeze handle in short bursts; Pull safety pin; Sweep; Aim.
• D. Sweep nozzle from side to side; Pull safety pin; Squeeze; Aim.

Answer: (D)

PASS means Pull, Aim, Squeeze, Sweep. The idea is to quickly enable the extinguisher, direct the agent where it does the most good, release it in a controlled way, and then cover the fire to prevent reignition. Start by pulling the safety pin so the extinguisher can discharge. Then aim the nozzle at the base of the flames to target the fuel source. Squeeze the handle to release the extinguishing agent. Finally sweep the nozzle from side to side at the base of the fire, moving the stream as the fire is knocked down. The effectiveness comes from activating the device, directing it at the fuel, releasing it in controlled bursts, and thoroughly covering the base area.
