I think many here are forgetting that when firefighters respond to a structure fire, they have absolutely no idea what is inside the structure. Holes in floors, gas cylinders, gasoline containers, illegal fireworks, live grenades, tear gas cylinders, and anything else you can think of are not uncommon to find. I've seen the youtube video, but if there are no lives in danger and a large amount of ammunition is burning and detonating, I'm not going near it because of the risk of chambered rounds, plus the chance there is something more dangerous in the same area as well.
