iPhone Auto-Combusts On Australian Airplane 277
First time accepted submitter thegreymonkey writes "Last Friday, an iPhone caught fire on flight ZL319 operating from Lismore to Sydney. This incident is under investigation from Australian Transport Safety Bureau (ATSB) and the Civil Aviation Safety Authority (CASA). This accident might be related to the iPhone battery again." Whether it "caught fire" may be a matter of semantics; as reported in the above linked story and by Network World (hat tip to reader alphadogg), though, the iPhone "started glowing red and emitting dense smoke."

Who said it was? To prevent things like this you have to take the battery out. Oh, wait

One hand gernade is less than a 20oz soda, high explosives aren't calorically dense, they are good at release.
You may as well say a gram of anything has huge amounts of energy (E=mc^2), extracting it is left as a thought excersize.

Actually, the standard "Do not use water with electrical fires" is based on the danger of electrocution.
'Throwing' water on something would work fine as there is no stream connecting you to the electrified component.
In battery-powered systems this is usually not a concern and water is a fine medium to put it out with ;)
Hell, in any modern house the GFCI (http://en.wikipedia.org/wiki/Residual-current_device) should trip long before you're in any danger of serious damage. More likely than not the power has already tripped if there is an electrical fire, or it will trip the instant the stream of water causes leakage current from the burning piece of hardware.
High voltage is of course a completely different scenario, luckily one most wont have to deal with... Like a water cooling system next to a 132kV transformer... ugh...

Not by any means are you correct. Battery fires are classified as metal fires, and require a class-d extinguisher.
You try putting out a lithium fire by throwing water on it - I dare you.

That would probably have been an exploded electrolytic capacitor. The small ones inside low power devices usually just blow their tops which are scored to act as a safety valve. The larger type capacitors can literally blow up like an M80 firecracker. I've seen photos of TV sets that had a hole blown in the side of the cabinet by a capacitor going "bomb".

You sir are incorrect, if it is the electronics burning, and not the battery, he is 100% correct in hist statement. If the fire is a result of the battery overloading then it is an chemical/metal fire. In which case water is a bad idea; chemical splash/just wont work on metal.
You're missing the point entirely.
The iphone 4 uses a "Built-in rechargeable lithium-ion battery. (http://www.apple.com/iphone/specs.html)
Putting water with Lithium is bad. (http://www.lenntech.com/periodic/water/lithium/lithium-and-water.htm)
Since the battery is damn near on fire, it's probably not wise to assume it remains intact and is not, in fact, leaking. Because if you're wrong, you get a pretty interesting reaction. Try YouTube if you'd like some examples, I trust you can locate the 'search' bar.

If the battery manufacturer screwed the pooch, its Apple's fault?
They would be accountable, yes.

For example, if your iPhone you've stored in your flight bag in the back seat spontaneously combusts while you are flying solo:
Now, think about an iPhone starting to combust in some passenger's pocket on a 737.
So, yes, it is interesting for you to keep saying that "it's a checklist item". but not really relevant. I've also never seen it in any small aircraft checklist I've been through. Are you referring to checking the engine compartment for bird's nests and the like? And what does your checklist say to do about "flammable objects"? I know that I personally carry a lot of flammable objects every time I fly. Those sectional charts are printed on paper, you know. That book of approach plates? The batteries in MY cellphone, and the ones in my aviation handheld radios. Until they changed the certificates, those pilot certs you are required to carry used to be printed on some pretty easily ignited paper. Now they are flammable plastic, but the medical cert is still on paper.
Do you remove all flammable clothing when you fly and fly only in Nomex?

Any power adapter should be able to survive a complete short on the output if it is designed properly.
And as we all know, the consumer electronics market is known for its high quality and attention to detail in their designs and build quality. ;-)
