What should be done if a lithium-ion battery fire is suspected?

When a lithium-ion battery fire is suspected, ventilating the passenger area while remaining alert for potential delayed fire ignition is the most appropriate response. Lithium-ion batteries can pose unique hazards, including the risk of thermal runaway, where the battery cells can overheat and reignite even after the fire appears to be extinguished.

Ventilation of the area helps to disperse any potentially flammable gases that can accumulate, reducing the likelihood of an explosion or further ignition. Additionally, being aware of the risk of delayed ignition allows responders to stay vigilant for signs of re-ignition or combustion after the main fire has been addressed. This approach prioritizes safety for personnel and any individuals in the vicinity of the incident.

The other options do not adequately address the risks associated with lithium-ion battery fires. Some suggest an approach that could lead to increased danger or insufficient response measures.
