40k people evacuated with no end in sight. Craig Covey’s non-update updates are enraging to the displaced.
They were taking readings of the outside of the container thinking everything was okay but this morning they got to see the gauge on the internal temp reading showing a jump from 77 yesterday to 90 today. That’s why the had the evacuation rescinded and now extended it again.

Lots of cool drone usage happening

I can already hear commentary in the USCSB video, "... at approximately 3:42pm the pressure release valve failed, releasing 150,000 pounds of MMA...".

Well, unless Trump has abolished it in the meantime.

Update: Unfknblvbl! He did actually try and abolish it. The safety authority that was created to prevent situations exactly like this one. https://www.thechemicalengineer.com/news/us-chemical-safety-..., and then Congress gave it a one-year lifeline, https://www.chemistryworld.com/news/congress-rescues-industr....

"There are three large tanks with a highly toxic chemical called methyl methacrylate, or MMA, used to make plastic, at the site in the 12000 block of Western Avenue in Garden Grove."

"In terms of the acute toxicity of methyl methacrylate, the LD50 is 7–10 g/kg (oral, rat). It is an irritant to the eyes and can cause redness and pain"

what is the toxicity of the partialy burnt smoke and byproducts? how BIG an explosion and fire? which fucking way will the wind be blowing when it pops? *please dont do disaster management unless you can run ALL the failure modes, and know you are missing something.
That actually doesn’t seem that toxic. Doesn’t seem like a carcinogen either. Obviously still bad, but at least we’re not talking about something on the tier of phenol or benzene here!
