The Civil Aviation Authority (CAA) has sounded a stark warning to travellers about the dangers of packing certain electronic devices in checked baggage as the summer holiday season gets underway, particularly in Scotland this week. Fires caused by lithium batteries are now the primary safety concern for aircraft, with a significant increase in incidents involving these devices.
Data shows a concerning trend: incidents of lithium battery devices found in hold bags almost doubled last year, rising from 316 to 643, while reports of overheating or malfunctioning also saw a surge, increasing from 123 to 206. The risk of a fire in the inaccessible hold poses a far greater threat, potentially going undetected until it's too late to control.
Lithium batteries are common in items like power banks, vapes, mobile phones, laptops, and smartwatches, storing substantial amounts of energy in a compact form. While incredibly useful, a defective or overheating battery can ignite a fire that spreads rapidly and is difficult to extinguish. The CAA estimates approximately two lithium battery incidents occur every week, leading not only to potential fire hazards but also to flight delays due to baggage removal or diversions.
Airlines UK Chief Executive Tim Alderslade described the risk from lithium battery incidents as a "growing challenge" due to the increasing number of electronic devices people carry. While pilots and cabin crew receive training to manage such situations, prevention remains the optimal strategy, starting with careful packing. Product safety engineer Giuseppe Capanna warned that substandard versions, often purchased from third-party sellers, are frequently responsible for these dangerous malfunctions.
To mitigate these risks, passengers must adhere to strict guidelines: mobile phones, vapes, and power banks must always be carried in cabin baggage, with a limit of two power banks per person. They are strictly prohibited from being charged onboard. Laptops intended for checked luggage must be completely switched off, not just in sleep mode.
