While most of us probably keep our laptops and other large electronics in our carry-on bags, the Federal Aviation Administration (FAA) still wants to avoid the risk associated with exploding lithium-ion batteries in the cargo hold of passenger aircraft. According to an official FAA document uploaded by PetaPixel's Michael Zhang, the agency is proposing a ban on large personal electronics (anything bigger than a cell phone) in checked baggage.
The FAA conducted 10 tests of laptops inside of suitcases. A heater was set against the lithium ion cell to force the battery to overheat. In one of the tests, a can of aerosol dry shampoo was in the suitcase. The currently permitted shampoo ignited from the overheating battery and caused a fire that could not be extinguished by a cargo-hold fire suppression system typical of most airlines. Other tests found similar results with other "dangerous goods" like nail polish remover, hand sanitizer and rubbing alcohol.
While banning this particular combination of items in checked baggage would be the logical next step, the FAA writes that doing so would confuse passengers even more. "We believe that it would be difficult for passengers to understand and correctly meet requirements that vary based on the specific content of their checked baggage," the FAA said in the document. "Complexity increases the likelihood of non-compliance and continued presence of the risk." Requiring that these items be carried on in airplane cabins remains the simplest method, according to the FAA. Cabin crews are more effective than automated cargo systems at stopping any fires from spreading, says the FAA.
The agency presented its results and recommendation to the ICAO Multidisciplinary Cargo Safety Group that met in Paris in July. Members of the group agreed to revisit the guidelines around large electronic devices, with plans to ban them from checked baggage altogether. The current document was presented to the Dangerous Goods Panel, a multi-national working group that tells governments what provisions to introduce into national legislation. The proposed ban is set to be discussed this week and next. We've reached out to the FAA for more details and will update this post when we hear back.
