That flash you see/saw...I noted it in another post as a volatile vapor flash. That's the ignition source, not a bomb. Something flashed over. I compare it to gasoline vapors flashing over to a gas can.

Under the right circumstances AA does explode. If a tank is leaking and the AA mixes with water...hydrogen peroxide forms...add heat from a fire you may attain a volatile vapor flash. I am not saying that is what happened as the plant had other chemicals onsight as well. But you have to consider what would cause two AA tanks to explode...which under normal circumstances pose no real hazard?

Makes sense. kinda like how you can put out a candle, light a match above the candle smoke, and the candle will re-light.

If it was the AA that exploded, that sure was a BIG BOOM!
