A single personal electronic device that overheats and catches fire in checked luggage on an airliner can overpower the aircraft’s fire suppression system, potentially creating a fire that could rage uncontrolled, according to new government research.

Regulators had thought that single lithium battery fires would be knocked down by the flame-retardant gas required in passenger airliner cargo holds. But tests conducted by the U.S. Federal Aviation Administration found the suppression systems can’t extinguish a battery fire that combines with other highly flammable material, such as the gas in an aerosol can or cosmetics commonly carried by travelers.
