Lithium Battery Fires — What They Mean and What to Do
What lithium-ion battery fires involve — from devices to grid-scale storage — the exposure concerns, and the steps affected people can take.
Lithium-ion battery fires range from small device fires (scooters, e-bikes, phones) to large fires at grid-scale battery energy storage facilities. The scale and exposure concerns differ widely, but a shared trait is "thermal runaway" — a self-sustaining reaction that makes these fires hot, persistent, and prone to reignition.
Common exposure concerns
Battery fires can release toxic gases, and large facility fires have been reported to distribute heavy metals across the surrounding area. Fine particulate matter in smoke is also a concern for people nearby, especially those with respiratory conditions.
What to do
Follow official guidance first. Limit outdoor activity while smoke is present, keep indoor air as clean as possible, and seek medical attention for breathing difficulty. Afterward, document what you experienced — see our guide on documenting your exposure after an incident. To check whether your area is affected, use the area-lookup tool.
Authoritative references
The EPA, local air districts, and county emergency management agencies publish guidance and monitoring data relevant to battery fires. We cite the specific sources for each event on its incident page.

Common questions
Why are lithium battery fires a particular concern?
Lithium-ion cells can enter thermal runaway, burning hot, reigniting, and releasing toxic gases and, at large facilities, heavy metals. Fires can be difficult to extinguish and may smolder for an extended period.
What should I do if there is a nearby battery facility fire?
Follow official guidance — shelter-in-place or evacuation. Limit outdoor air while smoke is present, and seek medical attention for breathing difficulty. Document any impact to your home or health.
