A lithium-polymer battery begins to smoke and swell after landing. The best immediate response is:
- AMove it away from people and flammable materials onto a non-combustible surface and let it burn out or use a Class D or ABC extinguisher as appropriate
- BPlace it back in the aircraft to contain the fire
- CPour water on it
- DPut it in a sealed container in the vehicle
Show answer and rationale
Correct: A. Lithium battery fires are self-sustaining; the priority is isolating the hazard from people and fuel. Water can spread burning electrolyte, and sealing it in a vehicle risks a larger fire.
- C — Water can spread a lithium fire.
- D — A sealed vehicle container concentrates heat and gas.
- B — The aircraft is combustible and valuable; do not re-contain.
