What is the correct technique for using a fire extinguisher on a bus?

• A. Use the PASS method (Pull, Aim, Squeeze, Sweep) and only for small fires; evacuate if needed.
• B. Push, Aim, Squeeze, Sweep and use for any size fire.
• C. Pull, Align, Squeeze, Sweep.
• D. Pull, Aim, Squeeze, Spin.

Answer: (A)

The main idea is using a fire extinguisher safely with the PASS technique and knowing when to evacuate. Start by pulling the pin to break the tamper seal, then aim the nozzle at the base of the fire, not the flames. Squeeze the handle to release the extinguishing agent, and sweep the nozzle from side to side to blanket the base of the fire. This sequence is designed to tackle small, contained fires quickly while keeping you in a safe position with a clear escape route. If the fire is spreading, you feel heat or we smoke becomes a threat, evacuate the bus immediately and call emergency services. Using a different sequence or trying to fight a fire beyond your ability isn’t appropriate, because the goal is to suppress a fire only when it’s safe to do so; otherwise, getting everyone out safely is the priority.
