Lithium-ion Batteries: A Growing Threat to Air Travel Safety

The increasing number of passengers carrying lithium-ion batteries in their electronic devices is leading to a rise in onboard fires. FAA tests demonstrate the catastrophic potential of lithium-ion battery thermal runaway, which can cause short circuits, escalating temperatures, and ultimately, battery failure with the ejection of molten electrolyte, flames, smoke, and toxic gases. While halon extinguishers are recommended, they may be insufficient, necessitating the use of water and other resources. The FAA prohibits external battery packs in checked baggage, yet many passengers still do so. A recent incident involving a South Korean Airbus A321 highlights the dangers, prompting new regulations. Southwest Airlines now requires battery packs to be in plain sight and prohibits charging in overhead bins. Experts stress passenger awareness and advocate for purchasing quality devices to mitigate the risks associated with cheap, potentially defective batteries.
