Is it not possible for them to just... spray it with ice cold water?

They have been doing exactly that for the past 24 hours. However the contents of the tank are polymerizing, that reaction is exothermic, and the tank is quite large.

I wonder if they’ll try drilling or shooting a hole into the bottom. A semi controlled leak to disperse it locally. A mess for sure. But better than going up and out.

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?

The plant has been around since at least the 1970s. At the time it likely was on the edge of town, but through 50 years of urban sprawl, the town grew around it.

It may be even older than that. My source for the age of the site is this 1970 NASA ALSEP supplier list (from the moon program!), which lists the address as an approved manufacturer on page 38: https://www.lpi.usra.edu/lunar/ALSEP/pdf/31111000671279.pdf

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.

It is however highly flammable and potentially explosive when sealed in a tank, which is the main concern.

And then we need to consider the byproducts produced when it burns - both nominally as well as the sort of extremely dirty incomplete combustion an explosion would produce.

Read the article. They have been doing that, but that is just slowing things down and buying them time.

Unprompted rules-lawyering is not productive or interesting discussion either

It's neurotoxic, a respiratory irritant, and an eye irritant.

No, if it's injected in your bloodstream it won't immediately kill you, but if you inhale a few milligrams of vapor you'll wish you could cough up a lung.

Also, the vapors are heavier than air, so if you fall in a ditch near the hypothetical blown tank you would likely suffocate and die.

Imagine how often this situation lie this would be happening without institutions like OSHA or the EPA. Stuff like this happens in Texas on a fairly regular basis, but it rarely ever makes national news.

From what I hear[1], we should be relying on the fact that environmental disasters are bad for business in a true Scotsman "free market".

Because greater Los Angeles is the USA's (post-)WWII aerospace hub disguised as a megacity and cultural production center? All sorts of folks spent the 40s-00s (scientifically) blowing stuff up in the hills, and manufacturing the resulting products down in the basin and points south. Those businesses needed labor, which needed nearby housing, and here we are.

That's... not really a reasonable characterization of LA's urban growth patterns. To begin with, Hollywood quite clearly predates the aerospace buildout in the 40's and 50's. It was an oil production and refining hub before that, and an agricultural shipping center even before the dust bowl.

This particular neighborhood in Orange County certainly looks aerospacey, but I bet the Disney-centered service workers in Anaheim made up just as much of the population as the industrial folks.

Big cities are big for a bunch of reasons, basically. There are no simple answers at this scale.

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… https://www.govinfo.gov/content/pkg/FR-2026-02-24/pdf/2026-0...

Yeah, what this administration calls common sense is more like dumbass sense than anything else. On almost every level.

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 believe they are having issues with the valves, from what I’ve read. But I’m just some guy.

They are having valve problems. One of the possible reasons is that it may be turning into a solid plastic.

If so, that could be one of the best outcomes. As long as it does not blow up before the process completes.

Yes, as of recent the third possibility mentioned by officials is that it will Turn into plastic and not explode.
