Battery-powered devices are overheating more often on planes and raising alarm
Battery-powered devices are overheating more often on planes, and that is raising safety concerns because of the fire danger
Devices powered by lithium-ion batteries are overheating more often during airline flights and passengers often put them in checked bags that go into the cargo hold, where a fire might not be detected as quickly.
Overheating incidents rose 28% from 2019 to 2023, although such events remain relatively rare, UL Standards said in a report released Monday.
E-cigarettes overheated more often than any other device, based on reports from 35 airlines, according to the report.
In 60% of the cases, the overheating — called thermal runaway — happened near the seat of the passenger who brought the device on board.
In July, a smoking laptop in a passenger’s bag led to the evacuation of a plane awaiting takeoff at San Francisco International Airport. Last year, a flight from Dallas to Orlando, Florida, made an emergency landing in Jacksonville, Florida, after a battery caught fire in an overhead bin.
More than one-quarter of passengers surveyed for the study said they put vaping cigarettes and portable chargers in checked bags. That is against federal rules.
The Transportation Security Administration prohibits e-cigarettes and chargers and power banks with lithium-ion batteries in checked bags but allows them in carry-on bags. The rule exists precisely because fires in the cargo hold might be harder to detect and extinguish.
UL Standards, a division of UL Solutions Inc., a safety-science company previously known as Underwriters Laboratories, based its findings on data from 35 passenger and cargo airlines including almost all the leading U.S. carriers.
