Recent data released by UL Standards has revealed a concerning trend regarding lithium-ion battery-powered devices overheating during airline flights. The report indicated a significant 28% increase in overheating incidents from 2019 to 2023. While such events are still relatively rare, the rise in incidents is alarming.
Among the various devices, e-cigarettes were found to be the most common source of overheating issues on flights. The reports from 35 different airlines showed that in 60% of cases, the thermal runaway occurred near the passenger who brought the device on board. These incidents can pose serious risks, as exemplified by a smoking laptop in a passenger’s bag that led to the evacuation of a plane on the tarmac at San Francisco International Airport.
Despite federal rules prohibiting the placement of e-cigarettes and chargers with lithium-ion batteries in checked baggage, a significant number of passengers admitted to doing so. The Transportation Security Administration (TSA) allows these devices in carry-on bags to mitigate the risks associated with fires in the cargo hold, which may be harder to detect and extinguish.
UL Standards based its findings on data from various passenger and cargo airlines, including major U.S. carriers. The Federal Aviation Administration (FAA) reported 37 thermal-runaway incidents on planes through August 15 of this year, with a notable 71% increase in such events from the previous year. The risks associated with lithium-ion battery overheating have been known for years, particularly after past incidents involving cargo planes carrying these batteries in bulk.
In the wake of these incidents, it is crucial for airlines and regulatory bodies to reassess safety protocols and regulations surrounding lithium-ion battery-powered devices on flights. With phones, laptops, wireless headphones, and tablets being the most commonly used devices onboard, measures need to be taken to prevent overheating incidents. Airlines must work towards implementing stricter guidelines to ensure passenger safety and prevent potential hazards due to battery malfunctions.
The increasing incidence of lithium-ion battery overheating on airline flights is a pressing concern that requires immediate attention and action. As the number of devices powered by these batteries continues to rise, steps must be taken to mitigate the risks associated with overheating. By adhering to regulations, raising awareness among passengers, and implementing enhanced safety measures, the aviation industry can work towards ensuring a safer and more secure travel experience for all passengers.
