Lithium Battery Fires Push the FAA to Tighten Safety Rules

The Federal Aviation Administration (FAA) has issued an urgent safety alert warning airlines about the risks associated with lithium batteries carried onboard by passengers and crew.

This alert comes in response to a surge in incidents throughout 2025 involving lithium battery failures that have led to fires or smoke within passenger cabins. For example, though not in the US, a 2025 air crash was traced to a fire ignited in an overhead bin due to a portable battery stored in carry-on luggage.

Lithium batteries are commonly found in everyday devices passengers bring aboard, including smartphones, laptops, portable power banks, e-cigarettes, and hearing aids. A malfunctioning battery can lead to a chemical reaction that causes overheating and possibly fire.

The FAA warns that lithium batteries stored in overhead bins or carry-on bags are concealed, difficult to access quickly, and not easily monitored. This can delay timely detection and firefighting onboard.

The alert urges airlines to reevaluate their policies on storing lithium batteries. For example, Southwest Airlines has implemented a policy that requires hazardous devices to remain visible during flights.

The FAA encourages advanced crew training for recognizing and suppressing lithium battery fires, including protocols for effective firefighting and proper use of thermal containment bags.
