Doesn’t need a detonator. AN will decompose with heat. As more mass decomposes( turns into gases which are volatile) it can increase decomposition until critical temp is reached, around 280 c for common AN.

Also, doesn’t need a fuel additive like petroleum to be an explosive. AN by itself is just a bit less “fast” an explosive than TNT.

So, a mass of AN, an uncontrolled fire, eventual decomp until critical temp of some portion is reached, then mass deflagration of the whole volume....

Well, well....... the facts come to light.

Thanks for that

I worked on farms in my ute. We used AN extensively as fertilizer. In retrospect I probably should of been more careful with the stuff.

Later in life we experimented with it's properties. It is not all that easy to trigger and expolosopn. That is why it used in mining in hugh and series quantities.. My bet is that we will never know what triggered this event.
