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

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

They are not. I said ice cold. I read this article and several other articles about this.

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?

Doesn't that mean they can bike to work there?

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

Surely they've had to get new permits over time as their operations changed? And why didn't the presence of the plant prevent the town from growing around it?

There's a home 430 feet away from it. At that point you didn't even try to create a buffer zone.

I guess you ask why they are using water at ambient temperature (20°C; 68°F) instead of very cold water (0°C; 32°F). Some reasons I can think now: They are using a lot of water, as most as possible, from pipes at whatever temperature it is. There are no enough mobile refrigerators, not enough electricity to make them work, and it's very hard to transport cold water or ice if you don't use the pipes. Also, the center…

Ah, that makes sense. It's too bad they can't drill into it to relieve pressure without destroying the integrity of the tank (not that I'd want to be anywhere close to it either).

If they didn't have to worry about it imminently exploding I wonder if they could somehow wrap it with reinforcement (e.g., wrap some high strength metal around the tank to prevent it from deforming when drilled into) and then drill into it to extract the liquid?

One of my other less serious ideas was to helilift a Chernobyl style containment structure around it, but I imagine they don't have one of those just sitting around waiting to be used.

The actual site of the tank is 33.78356416377991, -117.99993897629278 [1] - its in an industrial park, and its not a large scale chemical manufacturing facility. Its 'light manufacturing' for a company that makes custom formed acrylics for aerospace. https://www.google.com/maps/place/33°47'00.8%22N+117°59'59.8...

Perhaps "light manufacturing" is the wrong classification for this kind of business, then. Most of their neighbors are distribution warehouses, or companies doing machining or sheet metal pressing - if you ask me those are more in line with the definition of "light manufacturing" than the 7,000 gallon runaway exothermic reaction we're seeing here.

I get that, but the reality is that 40k people were evacuated. Shouldn't zoning be set up so as to prevent that? Light manufacturing in general is fine but it seems like these particular storage tanks might have been a bit too large for that location.

> I get that, but the reality is that 40k people were evacuated. Shouldn't zoning be set up so as to prevent that? It's funny that you would suggest this about California, where it is notoriously hard to build things. Accidents happen, it's not obvious that this was a forseeable outcome (happy for corrections from folks who have expertise in this area).

California isn't notoriously hard to build in - that's a result of it being incredibly conservative - not politically, but "anything that's built can remain forever, nothing new can be built" conservative.

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.

Provided the plastic doesn't need significantly more space than the source material, of course. We all know what happens when you try freezing a sealed bottle filled with water.

Their operations have not changed very much. They have always made acrylic windshields for airplanes.

This area is zoned as an industrial park, which doesn't require buffer zones. Probably city planners at the time just thought of them as a windshield manufacturer and didn't realize the potential risks.

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.

It's common sense if you're trying to make more money and are a psychopath.
