unfortunately thermal imaging 'sees' the temperature of the first non-transparent surfaces in its field of view so the engineers will need to come up with some gadget that's more intimate with the battery cargo that can get the "it's getting hot in here" message to the crew.
Without that hydraulic injector any heat alarm might not buy much more time, though. My gut feel is that by the time any practical device notices the temperature rise of a sizeable mass of batteries, the reaction is well established. OTOH, if there's a suitable flat surface nearby an extra minute's warning is no doubt praise-worthy.

Note: This is SQC's first and just recently converted BCF (ex. 9V-SPA). Not the first time I hear of false cargo hold fire warning's on the BCF.
A Singapore Airlines Cargo Boeing 747-400 freighter, registration 9V-SCA performing freight flight SQ-7866 from Taipei (Taiwan) to Tokyo Narita (Japan) with 4 crew, was enroute near Okinawa Island about one hour into the flight when the crew reported they had a fire alert on board and decided to divert to Naha (Japan) on Okinawa Island. The aircraft landed safely at Naha Airport about 30 minutes later, attending emergency services found no trace of fire.
The runway was closed for about 20 minutes. The cause of the fire alert is under investigation.

Oxygen needs
Air is a mixture of components the proportions of which change only slightly with altitude. For humans the two most significant in the short term are oxygen and carbon dioxide, oxygen makes the systems work carbon dioxide has control influences
The proportions may considered as having partial pressures in accordance with their fractional volumes. Normal air mix provides sufficient oxygen partial pressure up to about 10,000 ft although some reduction in body functions are detectable above about 8,000 ft. Above 10,000 ft increasing percentages of oxygen are required to be the equivalent partial pressure of air at 10,000 ft. Above 25,000 ft the equivalent partial pressure of even pure oxygen is insufficent because the overall pressure is so low that is less than the partial pressure would be at 10,000ft
The answer is to breath pure oxygen at increased pressure. This is called pressure breathing and is available to military crews who fly at these altitudes for short periods should the cabin pressure fail or the pressure hull be penetrated by enemy fire. In combat it is common to reduce the pressure setting to a lower level to reduce explosive damage from hull damage and the severity of cabin altitude change should it happen.
There are systems in place to allow crews to use high pressure oxygen but they involve carefull individual fitting of specialised equipment and are not practical for commercial flights. Pressure breathing is very tiring and ordinary oxygen masks don't work because the pressure makes the throat swell. The whole head must be encased.
There were other RAF aircraft using these systems but sadly they are gone. Those were the days

Pressure suits are not needed , oxygen masks will do just fine.
Only above 60.000ft a absolute need for a constant pressure suit becomes an issue.

Asiana Crash
Hardly a blip on the media radar screen here in the US!
Same as with the UPS crash in DXB.
A couple of "freight dogs" crash in a far out place. Sadly no one gives a damn!
Now, if a bunch of civilians had died and happened to be a slow news day, we would perhaps hear a little more!

Has FedEx ever made it five years without a hull loss in the past couple of decades? Much larger pax carriers like United, American and Delta certainly have as I recall.

New development on the Asiana accident.
Chosun Online is reporting that an insurance policy taken out by the Captain of the doomed aircraft is arousing suspicion, and an official investigation has been put into action.
Seems like the Captain signed up for life, medical, and accidental coverage, with payout totaling $3040089 USD in case of death. To make things worse, it seems the Captain signed up for all these policies in late May/June, thus had only paid into this policy for one month before the accident.
A new conspiracy begins......

Conspiracy?
Sorry if this is thread drift, butas the subject has arisen...Some years ago, a colleague of mine in his late 40s took out LOL Insurance, paid one premium and then went for his bi-annual medical. Whilst on the dyno-bike gizmo his heart began to flutter, the test was stopped and he was rushed to hospital with an incipient heart attack. Never flew again! These things happen.

It certainly may just be coincidence. Or, maybe not.

@ free at last
Nope, just sharing hardcore facts that was readily available on the net.
Asiana pilot have taken out 7 insurance policies Asiana Airlines crash may have been a suicide - eTurboNews.com
Would you care to share a FACT, not your BS intuition?? But before you do, learn to spell you YANK

You bloggers are a joke, crew had a cargo fire, airplane quits flying at altitude and you call it insurance scam, YOU should be ashamed of you'r self. 
) blogger has his brain switched ON here! 
Come on people wake up!
It's been about 4 full days since the accident, the wreckage, the bodies and CVR haven't even been fished out of the ocean yet, and only one blogger is smart enough to know the exact accident cause already?!
There's room for improvement here...
