What is the correct procedure for using a fire extinguisher, according to the acronym PASS?

Question

BlackTom AI · Accepted Answer

When evaluating the acronym PASS for fire extinguisher use, we need to map each word to the correct action sequence.
Option 1: 'Pull, Aim, Squeeze, Sweep' - This matches the standard PASS steps exactly: pull the safety pin, aim at the base of the fire, squeeze the handle, and sweep the nozzle from side to side. This is the correct sequence and uses the proper verbs.
Option 2: 'Push, Aim, Squeeze, Sweep' - The first verb is incorrect. You do not push the lever or handle to discharge the extinguisher; you squeeze it. This makes this option inaccurate.
Option 3: 'Pull, Aim, Start, Sweep' - The third word is incorrect. The action should be 'Squeeze' to release the extinguishing agent, not 'Start'. This misstates the mechanical step required to operate the device.
Option 4: 'Push, Align, Squeeze, Sweep' - This option contains two errors: 'Push' is wrong for discharging the extinguisher, and 'Align' is not the standard term used in PASS. The correct preparatory action is to 'Aim' rather than 'Align'.
