The Civil Aviation Authority has quietly issued an urgent safety alert to all British airlines. Sources confirm the warning targets lithium-ion batteries in power banks and vapes, which have overtaken traditional sources as the leading fire risk onboard aircraft.
Documents obtained by this newsroom reveal a sharp increase in incidents involving overheated or exploding portable chargers and e-cigarettes since 2023. The CAA alert, circulated to carriers including British Airways, easyJet, and Ryanair, instructs crew to treat any smoking or overheating device as an immediate fire hazard. Cabin staff are being retrained to use specialised fire containment bags and to douse affected items with water, not chemical extinguishers.
One cabin crew member, speaking on condition of anonymity, described a recent incident: “A passenger’s power bank started hissing mid-flight. Within seconds, smoke filled the row. We had to evacuate three seats and isolate the device. It’s happening more often than the public realises.”
Industry data supports this. The CAA reports that battery-related incidents on UK carriers rose 40% in the past year, with power banks and vapes accounting for 70% of those cases. The alert stresses that passengers must not place these items in checked luggage, and advises airlines to announce restrictions before boarding.
“This is a ticking time bomb,” said a former CAA safety inspector. “Lithium batteries are incredibly energy-dense. One short circuit and you have a fire that burns at over 600 degrees Celsius. In an aircraft, that’s catastrophic.”
The CAA’s move follows a similar directive from the Federal Aviation Administration in the US. But critics say the UK regulator has been slow to act. “We’ve been flagging this for years,” a union representative told me. “Now they’re scrambling to catch up after near-misses.”
Airlines are now updating their safety briefings and adding extra checks at the gate. Passengers may soon see more thorough inspections of carry-on items, particularly on long-haul flights where the risk is greatest. The CAA also advises travellers to use only certified chargers and to avoid packing multiple power banks together.
The economic angle is telling. The market for vapes and power banks has exploded, with cheap unbranded devices flooding the market. These lack the safety circuits of reputable brands, increasing the risk of thermal runaway. The CAA’s alert implicitly acknowledges a regulatory gap: consumer safety standards on the ground failing to keep pace with aviation safety requirements in the air.
One aviation safety consultant put it bluntly: “The industry is playing catch-up. The batteries got smaller and more powerful, and the rules didn’t evolve. Now we’re seeing the consequences in the cabin.”
The CAA declined to comment on the record, but an internal memo seen by this newsroom warns that “failure to comply with these new procedures may result in enforcement action.” For airlines already struggling with post-pandemic staffing and cost pressures, this is another operational headache. But for passengers, it is a matter of life and death.
As one veteran pilot told me: “In the old days, it was cigarettes in the lavatory. Now it’s these gadgets. But the fear is the same. A fire at 35,000 feet has no good outcome.”
