UL Standards has reported that devices powered by lithium-ion batteries are overheating more frequently during flights. Incidents rose 28% from 2019 to 2023, yet remain rare. E-cigarettes were the most common culprits, based on data from 35 airlines.

Lithium-Ion Battery Risks on Planes

Airlines are facing increased challenges with lithium-ion batteries overheating. These devices are often stored in checked luggage, posing a risk in the cargo hold. UL Standards highlights that thermal runaway incidents mostly occur near passengers’ seats.

Regulatory Measures and Incidents

The Transportation Security Administration prohibits lithium-ion-based e-cigarettes in checked baggage due to fire risks. A recent laptop incident in San Francisco’s airport highlighted the importance of this rule. Additionally, a Dallas to Orlando flight was forced to land after a battery ignited.

Survey Insights on Passenger Behavior

A survey revealed over a quarter of passengers store devices against federal guidelines. The Federal Aviation Administration noted a significant rise in incidents, emphasizing safety concerns.

Potential Dangers at Altitude

David Wroth from UL Standards states that thermal-runaway events at high altitudes can be uniquely hazardous. Past incidents with cargo planes prompted discussions on stricter shipping restrictions, but changes were minimal.

• Phones, laptops, and other devices are common on flights.
• 35% of incidents involved e-cigarettes; 16% involved power banks.
