I assume they removed the bang part first.

Funny story: When we had our explosives permit I asked our inspector: The Orange Book says air bags are explosive devices and are to be kept in a magazine and all other explosive rules apply. Is that right?

atf: yes, it is.

me: Then how is it just about every car has these in it but the drivers and owners not only don't have to store them in a magazine, under age kids and even foreigners are allowed to operate the vehicle. That's possession of an explosive device without a license, endangering a kid, and ... RUSSIANS can rent cars!

atf: um...err...ah...

me: well?

atf: um...

me: you said that already.

the Orange Book was later revised.
