When this is all over, when they peel the metal tank away, will they have a gigantic clear block of material?

#42By the miraculous grace of God, a crack allowed pressure to bleed & enabled our engine company to prevent thermal runaway. A BLEVE was the projected outcome, a firefighters worst nightmare - see the Kingman BLEVE - https://www.cityofkingman.gov/government/departments-a-h/fir...

Not only that, but "there's a gas leak, let's strike it with a wrench" is one of the more interesting attempts I've heard of to win a Darwin award.

I feel like these arguments are always framed as an evil corporation wants to take advantage of consumers. Except that's misdirection. The guilty party isn't the corporation, it's you, the consumer. And the corporations are already regulated. Heavily. You want Gore-Tex (expanded PTFE) boots, Cobalt EV batteries (Child labor in the DRC), Solar Panels (Open pit quartz mines), Wind Turbine Blades (Epoxy Resins & glass-l…
Consumers don't control zoning laws or risk mitigation details.

Re: That Methyl Methacrylate Tank
#47Why wouldn't there be passive protection systems designed in? After a big earthquake you don't want to have to also deal with other emergencies (à la Fukushima). Aside: One good side-effect of the 2011 Tōhoku earthquake being so horrific is that it stopped the self-obsessed whinging in my city (Christchurch was still trying to recover from an earthquake).

In California, this is absolutely not the case. Regulations are strict, chemical emissions are heavily restricted and proper disposal of chemicals via specialized companies at great expense. Chemical companies have no need of formulating new versions because everything causes cancer under prop 65. They absolutely have numerous permits for chemicals, your claim that they don't denies reality.
This case probably fell through the cracks, was grandfathered in due to military importance, or is a symptom of the utter lack of industrial knowhow plaguing modern US manufacturing because much US manufacturing is legacy work from decades ago with little ability to modernize, at a plant that likely existing long before the nearby housing.

You’re reversing causality. People don’t want gore-tex, and they don’t want cobalt batteries. They want dry boots and transportation.
If some corporation comes along and says they have dry boots and electric cars, it is not realistic to expect every single consumer in a society to become expertly informed on fluorochemistry or the economics of mining, and then also expect them to make the decision that is best for all of us.

The spark could have caused an explosion.
I read that was the primary concern and wondered about drilling/piercing techniques that could avoid a spark. Spraying water sounds like the dumbest one but some kind of mud applied or something. CNC machines don’t seem to be light shows but i know very little.
My "I have no clue how this works" proposal to minimize the chance of sparking would be to re-purpose a waterjet cutter...

I believe they tried to inject some chemicals to slow the reaction, but the pump and/or valves failed and clogged.
That is active. Something passive could be submerging the tank in a pool of water (also good for proving spill containment won't leak).
Uh, you can't just disconnect a pressurized 35,000 gallon tank and drop it into a an enormous pool you just keep full under it at all times.
