Federal aviation administration (FAA) A security warning issued Uncontrolled on Tuesday associated with the risk of risk of fire lithium battery,
The spare lithium battery is commonly prohibited in the goods check, but even in the carry-on baggage, they can pose risk and risk to passengers and crew members.
Lithium batteries are also often found in cell phones, computers, portable chargers, hearing aids and other devices, which can upset and create “thermal runway events”, where the pressure and temperature grow rapidly and can ignite the fire on the fire.
The FAA said that this is especially dangerous when the batteries are not in plain vision.
“Lithium battery, passenger overhead compartments and carrie-on baggage can be unclear, may be difficult to reach, may be difficult to arrive, or not easily monitoring by passengers or crews. Due to this, the thermal runway and firefighting measures may be delayed in detection, the flight may increase, increase the risk for security.”
The FAA recommended the airlines to modify their “traditional firefields” to take into account the appropriate response to thermal runway events, which “needs to use large amounts of water to cool the battery and suppress flames.”
While Halon can briefly press the open flames, they do not prevent the rapid spread of energy included in thermal runway events.
“It is necessary to cool the device with water to continue the response until all cells have discharged their energy.”
Aviation officials advised the airlines to re-look at their safety materials to ensure that they are the best advice to the passengers to handle and store the battery so that they do not have damaged or short-circuits-which can occur when the battery can occur when the battery exposed terminals touch other metals or keys.
Comes as alert FAA has registered an increase In recent years, the number of safety incidents associated with lithium battery. So far in 2025, 50 incidents have been verified and seven were still pending as September 2.
In 2024, 89 incidents were recorded in 2023 compared to 77. In 2022, 75 incidents were recorded in 2021 compared to 54 incidents.
From March 2006 to August 2025, the FAA recorded 648 verified lithium battery incidents, of 252 of which were from batteries, 138 of which were from e-cigarettes or vepping devices, of which 97 were from cell phones, 81 were from other electronic equipment, 77 were from laptops, and 3 were from medical devices, and according to the agency, according to the agency.
