Slight misinformation. The O2 generators were not labled as hasmat and it is thought that a un secured tyre was also in the cargo hold, suspecting a impact with the box of generators.
Also, it is not a matter of pulling the pins out of O2 generators but installing a shunting cap that grounds the 2 pins that activate them together preventing them from discharging from as small of a current as electro-static.
This is off topic.
