Apparently fire and air bags do not mix.
Sodium Azide (2 NaN3 ) is used to inflate the bag. It does not like heat and goes bang at 300 °C. It then breaks into Nitrogen and Sodium. We also know that Sodium and Water do not dance well together and we end up what we see in the video.
And now you know you are driving around with an explosive device aimed at your face. Have a good day.

In the mid 90’s, I worked at a independent shop in Texas. This was when airbags were becoming a big thing. I was working on a Taurus with the first generation airbags. All I had to go on was a book, so a trip to the dealer was in order. They had a tech that did all the airbag work. We talked at length about what was probably wrong and I got a good lesson on how airbags work. I thanked him and as I was leaving he asked me if I had ever been hit with a airbag. Of course I hadn’t. His parting words were”it hurts like hell”.
After I left the independent shop and moved to a better(?) job at a dealership in Iowa, I got a lot more airbag experience. That first shop and two dealerships later, I never did set one off. Back then a airbag, used at the scrap yard was nearly 1000 dollars. New ones were around 1400. The wife’s Buick minivan has the 2nd generation airbags that aren’t as violent when they go off.
If you happen to have a older car with the 1st gen airbags and have a accident, it’s going to hurt. I don’t know what’s in the newest version, but unlike the originals, they won’t embed your glasses in your face if they go off.

I do not like airbags. They provide a false sense of security, increase the effectiveness of seatbelts by only 3%, actively cause several additional injuries(engagement ring surgically implanted in your FACE, anyone?), and can knock you out during standard operation. Also a friend of mine who is a mechanic dreads working on cars which have airbag systems because they’re kind of really unstable and can deploy when you’re working on them up close and personal as opposed to sitting in the car like you’re supposed to.
That fireman, on the other hand.
*spray, spray, spray,* “KABOOM!” “Huh.” *spray spray spray*
The first lesson I learned was how to disarm them. Mostly it’s just unhooking the battery and waiting 5 minutes. Never had one go off in almost 20 years.
Good to know, I’ll remember that.
