Air Tank Safety

Makes you wonder how much of that was due to compressed gas and how much was the oxygen exploding in flame. Considering that they had to extinguish it afterwards I'm guessing it was mostly the latter.

Once you start compressing oxygen in concentrations that are higher than what's in air, (20%), you have to be very careful about cleaning and lubricating the components involved as it can spontaneously burst into flame when exposed to anything flammable, I'd guess that the oxygen from that tank encountered cooking grease or something and that triggered the blast.
 
If it was a oxygen tank (not a air tank like what we use) there was probably not a lot in it as I think the explosion would be a lot bigger. But pure oxygen under pressure will ignite oils. I doubt the tank broke but what probably happen was the valve on the tank broke.

Im not a respiratory tech, but know a bit about the subject & yeah, it's an oxidizer so that makes way more sense than a simple burst oxygen tank.

All it'd take is a hot cigarette butt or some smoldering BBQ ashes tossed into that heap

I wonder if it was one of these. I saw one in Lowe’s a couple days ago, appears to have very little oxygen in it because it was extremely lightweight.
Both of those workers were very lucky that they weren’t hit with shrapnel. Obviously a garbage truck has lots and lots of paper products. And other disgusting things. Kudos to the worker that quickly ran and got a fire extinguisher and kept an eye on the fire that ensued.
