• B. Push, Aim, Squeeze, Sweep; used on all fires.
• C. Pull, Alert, Squeeze, Stop; used on large fires.
• D. Pull, Aim, Squeeze, Stop; used on any fire.

Answer: (A)

PASS is a quick guide for using a fire extinguisher safely on a small, early-stage fire. It stands for Pull, Aim, Squeeze, Sweep. Pull the pin to break the tamper seal, Aim the nozzle at the base of the flames, Squeeze the handle to release the extinguishing agent, and Sweep the nozzle from side to side at the base of the fire until it’s out or you can no longer reach it safely. This method is appropriate only for incipient fires that a trained person can handle with a clear, safe exit path. If the fire is large or spreading, evacuate and call emergency services instead.
