A contractor showed me how to fix dents in granite with superglue. It’s totally clear. The trick is to scrape it with a razor blade at a 90 degree angle (strait horizontal). The imperfections become nearly invisible.
I've been told this is a cheap way to fix small windshield cracks. Never tried it but sounds like it would work for the small spider sized and shaped cracks from small rock impacts.
I expect something with a lot of small bubbles and cracks, also it also overheated and got weird decomposition and reactions, something like a overcooked/toasted meal. Reusing a comment that I made in a previous thread:
For comparison, there is a nice video by NileRed https://www.youtube.com/watch?v=phNLecfyWS8 He is making Bakelite that is a type of plastic. It's a tiny amount, in a lab, on purpose and he may make a few attempts. Anyway it overheat and instead of a nice piece of plastic he got a nasty block of foam with burned plastic. No imagine a huge tank of a similar chemistry reaction.
Why 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).
Based on the article, the inhibitor chemicals _are_ the passive protection system, they just can't be perfect because too much of that stuff ruins the purpose for having the chemical in the first place.
It can actually make it more dangerous in some ways. When you go to use it, too much inhibitor and the conditions needed to start the reaction will start to get wild, so the reaction will occur faster once started.
> The use of high levels of inhibitor can cause the monomer system temperature to far exceed the onset temperature of thermal polymerization under external heating. Once the inhibitor is exhausted, the thermal runaway reaction proceeds at an elevated temperature with a substantial reaction rate and very little reactant/monomer consumption.

Because the US chemical industry has been effectively unregulated for a century and can do whatever it pleases.
There's a neutralizing chemical that could have been injected to stop the exothermic reaction in its tracks. They didn't have it on site. A "response team" (likely a contractor that responds to chemical emergencies) did, but by the time they showed up, supposedly things were too damaged to inject it. That neutralizer should have been a Big Red Switch away.
They also should have had a deluge system, for example, to cool the tank. With a standpipe for firefighters if there's no water available onsite. Was there? Nope! No requirement for it. Despite the dangers of this stuff being very well documented, it having caused disasters before, etc.
Consider that the chemical industry can invent a new chemical and the onus is on everyone else to prove it is hazardous. So what does the US chemical industry do? Spend lots of time "innovating" new versions of chemicals to constantly leverage the 'innocent until proven guilty' scam. Chemical A is found to be cancerous, so they rework it slightly, enough to call it a new chemical even though it's nearly the exact same thing, but we're right back to square one on it "not being hazardous."
Protection systems cost money. If something really bad happens the cost of the disaster far outweighs whatever assets the company has hanging around, and in the US, we basically never hold anybody responsible for what they do in the course of their job running a corporation. GM willfully ignored problems with Chevy Cruze ignition switches that caused countless people to die because they'd randomly shut off _and shutting off meant the airbags would get disabled_. Did anyone in those teams, or their managers, ever get held accountable? Nope, not except in some civil suits, where Chevy repeatedly claimed they didn't have any documentation. Well, at some point Congress went after them for something, and in the massive pile of documents lo and behold there wer piles and piles and piles of documentation about the ignition switch issues.
A company like that isn't even required to carry a lick of insurance, far as I'm aware. Meanwhile, and I wish I were joking on this - if I want to get a permit to set aside space in front of my apartment building to park a moving truck, I have to carry a million dollars insurance that protects the city.
If I park my car blocking an ambulance I get charged with at least one crime, possibly even manslaughter or homicide. Ditto for blocking a fire truck trying to get to a fire. A railroad can do it to half a county, dozens of times a year, and everyone just shrugs as people are harmed or killed, or half a neighborhood burned down. All because private equity is milking the railroad so tight that it's making trains that are miles long instead of lengths that are appropriate for the tracks they're on and won't block fire trucks, ambulances, police cars, school busses, and the general population as a whole.
The free license corporate America gets to shit all over society has got to stop.
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
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-like fibers), and so on. All those things sound nice and good for the environment but don't appear out of some magical horn of plenty. All those things require intensive chemical and industrial processes that cost a lot of money.
"Just make the government solve the problem by criminalizing their entire operation" isn't a serious solution. It's a generic anti-corporation/NIMBY argument to outsource uncomfortable things to another country without labor or safety protections. Consumers need to accept that if they want nice things those things come with some amount of cost to the environment and level of risk. The government needs to work with corporations to find the safest _practical_ mitigation that doesn't bankrupt them. If that's done correctly you will actually avoid accidents like this because everyone is working together on the same page.
Wow that is a hell of a lot of responsibility to heap on the consumer. I think the right/rational argument is properly regulated safety procedures for storing large quantities of extremely hazardous chemicals. There is a middle ground. This is in my view a regulatory failure if I ever saw one… who was inspecting this tank and what were they looking for? I am willing to bet the gas pump nearest me gets more attention from whoever is responsible for weights and measures.
By 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...
It's ok to just treat it like a thing people say. When people say 'bless you' I don't explain to them that sneezing doesn't actually expel my soul from my body.
> I always love how religious fruitcakes think that their 'god' both is completely omnipotent and infallible but also somehow gives a shit about them, and listens to them.
Such a miserable existence looking down on people for their own beliefs. Please get a hobby.
You don't believe in anything, good for you. But it's not healthy for you to harbor so much hatred and anger for those with different opinions. You're free to worship your golden calf, but why not be civil?
Seems more like the miraculous grace of incompetence and no maintenance. You ever have a problem at work and you procrastinate long enough and it just sort of goes away for “reasons”? This kind of reminds me of that. Not maintaining the valve was saved by taking even worse care of the tank.
What a disaster and complete failure on the local government in the way they handled this situation. If we ever get hit by an earthquake or other larger disaster, it's safe to assume we're all on our own.
Also, as someone affected by this, it has been extremely frustrating getting updates via xitter. Do we really have no other options?
I had wondered the whole time why they didn’t just pierce it with an AM rifle. Would that not have been better than a random partial failure via a crack?
Genuinely open question. I don’t know anything about stuff.
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.
> The immediate danger seems to abated, fortunately,
The "it will explode leveling a couple city blocks" danger seems to be abated, but instead it's spraying an insanely toxic chemical out into the open, which will likely have health repercussions for residents for decades?
Thousands of gallons of toxic chemicals don't just disappear.
It probably polymerized completely and it's a giant block of nasty looking solid plastic, that perhaps can be lifted with a crane (with some support, in case it has cracks or something).
In some plastics the monomer is toxic, but the polymerized form is safe. (I think it was use for windshields for planes, so once polymerized it was probably safe to touch at least.)
In this case it was an uncontrolled reaction so I'm not sure if someone knows the exact current composition of the goo, so I strongly recommend to avoid licking it.

Something passive could be submerging the tank in a pool of water (also good for proving spill containment won't leak).
Because the US chemical industry has been effectively unregulated for a century and can do whatever it pleases.
