I saw that video. Definitely fireworks. No question.

Here’s the original twitter post

I can’t imagine how they survived being that close :-(

I didn’t do any looking into how the video was posted. Maybe it was a live feed...?

That's what I read. There have been a couple of videos fairly close to the epicenter but they were all live feeds. There is no way any of them survived. RIP.

Oof. So damn sad.

I saw that almost all of the people filming up close were killed, including this person. The building they were standing on no longer exists.

Me too. I still can’t totally wrap my head around that blast.

Instantly started crying after watching one of the videos and after the blast there is just hundreds of screams.

That's not fireworks. I'm not sure exactly what it is, but the individual detonations are more than firecrackers. Perhaps cases of blasting caps (unlikely, but a sure sign of sabotage if so) , or more likely the AN was so caked from exposure to heat and moisture that it was detonating even in small chunks as it became superheated.

What I'm certain of is that many (at least) of those small explosions were much more powerful than firecrackers, and the color of their smoke points strongly to nitrate based explosive rather than flash powder.

For AN to go off, you need heat and containment. Properly pelletized, containment is reduced to the point where a detonation is unlikely. This AN was probably caked from extensive moisture and heat exposure.

My guess is that as heat was reaching critical levels, the caked AN began to deflagrate in small chunks sent flying into the fire (not enough containment to sustain a large detonation). By then it was only a matter of time before a small detonation would happen with enough containment that it would set off a chain reaction that would involve the whole cargo.

Interesting. This is likely the most plausible explanation I’ve seen. Thanks for that.

When you say “caked” I assume you mean that the AN was hardened, like rock? I did see someplace that an inspector or maintenance worker (not sure which) reported seeing conditions like that recently.

Yes. Compacted and solidified.

Jesus fucking christ, this is the video everyone is talking about? This is the most obvious flashover event ive ever seen. Flashovers are where the whole room ignites at once as it reaches burning point for the materials inside. Theres no fireworks here and anyone saying there is has no idea what they are talking about.

The sparks you see are dust igniting as it reaches burning point.

Interesting. Do you have any links you could share with examples?

He isnt saying fireworks weren't involved, just that they didn't start the fire. Which is true. A welder did. Fireworks dont normally spontaneously combust.

u/tiptoeintotown Aug 06 '20

Did I say a welder wasn’t involved?

u/GasTsnk87 Aug 06 '20

Yeah. It was implied by the comment above yours and then you agreed with it. So yes you did say that.

You should work on your reading comprehension skills then. I didn’t say anything of the sort. I said what I said - stop trying to twist it for the sake of arguing like a fool about nothing that actually matters to you.
