[QUOTE="Truckdriver, post: 3402233, member: 45123"] There was a fire in the fireworks factory next to the AN storage warehouse. Here is video of the fireworks factory right at the first explosion [URL]https://mobile.twitter.com/Woj_Pawelczyk/status/1290756576849133570[/URL] You can see the rapid pressure and fire work it's way out the windows The 2nd blast was moments later. The thing about AN is that it isnt inherently explosive in its "relaxed" state. You can set a match on it and no boom. It takes a bit of work to get it unstable enough to be explosive. You have to either mix in additional ingredients to change the composition, OR you have to apply heat AND pressure. Heat and pressure make it definitely unstable through oxidation Here is a news article from 2019 in Arkansas about a truck full of AN that had a brake fire. The fire grew and applied heat to the tank which created a lot of pressure, then either the tank split or the fire worked it's way through to the AN and the whole thing detonated [URL]https://www.arkansasonline.com/news/2019/mar/28/blaze-sets-off-fertilizer-load-rig-driv-1/[/URL] The welders might have made a small fire or not been at cause at all for the AN to go off. They might have started the fireworks factory fire though. The main reason the AN went off, according to theory, is that the fireworks factory fire radiated enough heat to begin to destabilize the AN. Then the initial factory explosion created enough pressure to finish the instability. Then add an ignition source such as flaming debris from the initial explosion, and BLAMMO!
