Thank you for linking us to this.
As a retired FF i have always known that ammo is hazardous but of course back when, we had very minimal turnout gear compared to the gear worn today, but aerosol cans are much more dangerous in a fire.
I would have liked to see some 1 and 8 lbs canisters of powder included in the tests and some Black Powder ammo dropped and run over by that dozer.
I don't know where SAMMI boundary's are in those areas.
I however would not have stood behind that truck while blazing because there is still an unknown here and prudence would to me dictate to not expose yourself to anything if not absolutely necessary.
I sent this to our fire chief for use in training.
