It does definitely sound more like a lung condition from the packing talc than anything to do with the chemicals in the explosive flash - as said they have filters.
Forgive me if this is a stupid question, but why do they need an explosion anyway? Would it not be easier to have a small very high pressure canister of inert gas that fires to inflate the bag? Or would the inflation not be quick enough?
Firstly you need to put that compressed gas canister somewhere - it is hard enough packaging all the components of a modern car without trying to fit a scuba tank in too! Forgive me if this is a stupid question, but why do they need an explosion anyway? Would it not be easier to have a small very high pressure canister of inert gas that fires to inflate the bag? Or would the inflation not be quick enough?
Also can't guarantee that the compressed gas canister will maintain enough pressure to deliver the correct amount of gas throughout the 15 year lifecycle of an airbag.
ETA - oh - and it is not an explosion it is a rapid release of gas but there is no shock wave, if it exploded you would be dead....actually didn't Honda have a problem recently where some of their airbag initiators DID explode and one person was killed?

Side airbags do not remain inflated.... they would impede a persons escape more than front airbags.
dont know why any one would hang around breathing in any fumes when i was smashed into my first priority was to get the hell out of dodge
Surely it was to get the hell out of (Peugeot?)?dont know why any one would hang around breathing in any fumes when i was smashed into my first priority was to get the hell out of dodge

Ya it was a 407. i was going along minding my own business approaching a corner . a nissan micra cam around said corner a way too fast lost control and skidded sideways down the road and straight into me . The impact was so large that the engine and gearbox was ripped straight out of the micra. Right before impact i closed my eyes . afterwards i opened my eyes and seen was seemed to be smoke (most likely the talc) and then just gut the hell out of there.
The Airbag is really sore when it hits you in the face !!!!

There was one case of a police driver who ended up in an accident, the airbag deployed whilst his arm was 'over' it - it damaged is arm/ shoulder so badly, he never regained full use of it.

Not a silly idea as that is exactly how a great many modern side & passenger airbags work. They have a small pyro charge to burst a disc that releases the gas. An alternative is the 'hybrid' which has a larger pyro element that heats the gas for a higher output.Whilst I'm not aware of the technologies used in the car in question Sodium Azide has been phased out of the majority of airbags for several years now.

Was the airbag completely inflated at the point when it was punctured (and thus merely expelling nitrogen gas)? I guess we'll never really know.
Well actually I guess we will considering that it's impossible to burst an airbag......as it's already got holes in it to let the gass out as soon as it's inflated WITH HYDROGEN.http://www.youtube.com/watch?v=hO5syWQQlAI
Having been to an awful lot of rather bad RTC's I would offer that airbags don't save lives, they prevent additional injuries once a seat-belt has saved your life. The arguement is quite simple; take any collision scenario and in one example use just a seat-belt and in the other use just air-bags; I know where my best bet would be.....
Tragic for the family but so very difficult to prove a direct link between the fatal pneumonia and the airbag chemical.

You'd have to be nuts to fill a crashed car with hydrogen.

Oh no, a 'dagerous' chemical in a car!! Excuse me guys, but we happen to driving around with the second most powerful explosive in the world in our fuel tanks. Petrol. I think we should've been told !!
Surely there are plenty of explosives with a higher yield than petrol? It's not very explosive just sat in a petrol tank either.At TVR, Peter Wheeler's philosophy was " “If someone crashes one of my cars and it’s their fault then I can live with myself. If we were to put an airbag in one of our cars and it ended up killing someone, I couldn’t live with that ”.
I understand that he believed that in the event of a "roll-over" accident in a convertible, the driver's head would be pushed into danger by the air bag?

I'm calling b
ks on this story. As an airbag engineer for many many years, there's no way that the airbag brought on his pneumonia. This unlucky fella may have got a lung full of talc but that's it. True a pre-existing condition may have been aggravated by this but if the side window was smashed, how much of the stuff could he have realistically breathed in? The propellant is a red herring. Minor burns are about as bad as it gets from a driver airbag.
On another note, cold gas inflators do exist for knee and curtain airbags but there's no room to package one in a steering wheel so pyro inflators are used which are much smaller. They get hot but it's a small price to pay.
Lastly, seatbelts do nearly all the work as said above but I'd rather have some minor burns and slight abrasions than a steering wheel in my face.
