So, no leak.
If you would like to learn more about these types of incidents, the US Chemical Safety Review Board has a fantastic series of videos on YouTube: https://www.youtube.com/user/USCSB
They explore the root causes of historical accidents. Importantly, they do it from a broad perspective: not just the chemistry, but the human factors, the decision making, and the process failures that led to the accident and how to prevent such things in the future.
I'd be curious how it came to pass that 40k people were living within the blast radius of a plant processing toxic chemicals. Isn't this sort of thing the primary justification for the existence of zoning laws?
MMA (this stuff) hardens when exposed to sunlight. The tank and valves are outdoors.
I would not be surprised to learn that is why the pipes/valves/etc are "gummed up" (to use the term from the article) - people who touch the valves/etc probably have mma on their hands/gloves, and then because those are outdoors, it eventually hardens.
Or something similar.
Why can’t they drill it and pipe it off into some drainage pipe for cooling or collecting in trucks?
Divide and conquer
Where are all of the humanoid robots? Get them in there with whatever the oil and gas industry uses for tapping pipes/containers under pressure. I'm only half kidding.
More fire / explosion risk than the "toxic cloud engulfs city" rhetoric people have been spreading.

They talk about the possibility of a spill going into the environment, but if they know it might spill, can't they make it spill and capture it?
Is it not possible for them to just... spray it with ice cold water?
The LD50 of methyl methacrylate in rates is 7-10 g/kg. In comparison, the LD50 of table salt in rats is 3 g/kg. So it's not a highly toxic chemical.
They say it will fail for sure, either leak or explode.
I wonder why they can't drain the tank into another facility. Maybe they just lack an appropriate container.
I love how the current title of this post just assumes that everyone lives in California.
There are other "Orange County"s in the U.S.
Worth mentioning that in February the EPA proposed to severely deregulate chemical facilities like the one in Garden Grove, gutting third-party audits, hazard reporting, and public transparency requirements. They titled it the ‘Common Sense Approach to Chemical Accident Prevention.’ The public comment window closed just eleven days before this disaster…
