Boeing Warns Carriers About Flying Bulk Shipments of Lithium Batteries

It's lithium ion batteries that power the iPhones, iPads and other iStuff that have come to be regarded as the essentials of life. Only problem is, they tend to catch fire, leading Boeing Co. to warn airlines that loading up their planes' cargo compartments with bulk battery shipments pose unacceptable fire hazards.
There've been plenty of cases of individual phones and other devices catching fire, both on the grund and in the air. Just one blazing phone is a problem; think what a blazing pallet of burning batteries could do.

That, says the Wall Street Journal, is what led Boeing to issue a formal warning to its customers, urging them to stop accepting large shipments of lithium batteries until safer packaging and fire protection efforts can be worked out.
Let them take a slow boat from China, Boeing advised, though not in so many words.

Nothing new

It's hardly a new problem. There have been many case over the years of cell phones igniting in people's pockets, on airplanes and in other inconvenient locations.

Last August, an airplane was evacuated in Tel Aviv after an iPhone 5 caught fire and filled the cabin with smoke. Last July, a smartphone caught fire under a 13-year-old girl's pillow in Dallas. And way back in 2008, a laptop computer caught fire in a vintage pickup truck in Nevada, destroying the truck, a Remington rifle and setting off two boxes of ammunition.

Boeing has reportedly been giving the no-big-battery-cartons advice to airlines who asked but has now issued a formal warning to all of the world's carriers, who are expected to comply. Airlines that disregard the warning would be on shaky legal ground in the event of a disaster attributed to flaming batteries.

Feds pondering

Boeing at least beat the U.S. government, which has been considering rules limited lithium batteries in carry-on luggage since 2007. In March 2007, the Department of Transportation said there had been five fires in airplane passenger cabins or cargo holds since 2005, a period of only two years.

Lithium metal batteries were banned from the cargo holds of U.S. airliners in 2004 but lithium ion batteries -- which are much more common -- are still good to go.

Lithium metal batteries are nonrechargeable while the lithium ion type is the one we're all familiar with -- requiring frequent plug-ins to keep the juices flowing.

The problem is that other things can get the juices flowing as well. Both types of batteries contain chemical-infused metals that get very hot very quickly if they come into contact with each other due to a short circuit or leaking seal. The result is a fast-spreading, very hot fire that is very difficult to extinguish.

While a single battery catching fire in a phone or laptop may start a small fire, a battery catching fire in a shipment of thousands of batteries could start a blaze that would quickly become catastrophic. 

Many airlines have already stopped accepting battery shipments and Boening's warning may push the recalcitrants to act as well. While Boeing's warning doesn't have the force of law, airlines nearly always comply with formal warnings from manufacturers, so Boeing may have accomplished what governments so far have not gotten around to.
