How would one know though by just looking at the device? I have chassis that came with Intel 11th gen, but the brainboxery, keyboard, battery, touchpad -- all have been swapped over time.
It's possible to drill or cut without creating sparks. Just need to control the speed of the cutter.
Besides, tanks like these have various portholes, valves and drains already. The article mentions an "inoperable valve" so maybe that's the problem but I'd be surprised if there were just one. They must have been getting the contents out of the tank and into the manufacturing process somehow.
Does this mean that we should shoot holes in it like cowboys to relieve pressure, or does that instead mean that we should not shoot holes in it like cowboys to relieve pressure?
(Because, I mean: If this thing is as sketchy as it is made out to be, then nobody is just walking over there with a spanner to loosen a cover. There aren't enough dollars nor PPE available to make this happen.)
Shooting holes in pressurized vessels with explosive stuff is probably a very bad idea, as outlined in my comment[1]. Slowly loosening a valve is a better idea.
That being said, in no way, shape or form am I an authority on the subject.
The standard choice for MMA processing is actually stainless steel, because carbon steel/iron/etc scavenge the inhibitor used to prevent thermal runaway.
HDPE would work, and often how it is transported in drums, but for actual processing, everything would normally be spec'd as stainless steel.
Which, of course, is pretty spark resistant to begin with.
Even if this wasn't true, this is not a hard problem, you can use non-sparking tools, proper coolant, lots of things to avoid sparks.
Or you know, we could require that highly flammable materials subject to thermal runaway have "drill here in case of emergency" patch of non-sparking material or something.
The cost of ATEX/Class 1 Div 1 compliance would not really go up if you required this.
Inb4: I don't work in the industry, my knowledge is limited to a faint memory of a college course on fluid dynamics.
If I recall correctly, high pressure ignitable stuff can spontaneously turn !!FUN!! in absence of heat if it is suddenly relieved through a pinhole. Basically jet is followed by a ring-like zone where the stuff mixes with oxygen. Jet creates tiny zones of very high temp, thus igniting the mixture ring that follows.
Maybe the thought process is that leak would effectively be pressure normalizing over a larger area and more gradually than creating a tiny hole, so whatever I said about jet ignition would not be applicable
So MMA has a fairly high autoignition temperature - it's >815F (gasoline is like 475F).
It also has a fairly small explosive concentration range (2-12%).
(the inhibitors it gets mixed with are about the same autoignition temperature, but have higher flashpoints).
In any case:
1. The pinhole issue can be resolved pretty easily by making a big hole instead of a small one :)
2. MMA is normally stored at ~0psi. The increasing pressure here is from runaway polymerization boiling the liquid (the runaway comes from the polymerization being strongly exothermic). These tanks are not built to handle very much pressure, usually a few psi max. I doubt whatever the tank pressure is currently qualifies as the kind of high pressure you are talking about.
3. There is apparently a significant crack now that is relieving most of the pressure. Which is preventing it from bursting. Assuming the crack didn't exist before this all occurred (so far the prevailing theory is it did not, but who knows how it will turn out), it almost certainly started as a pinhole that propagated, so if it was going to ignite the way you said, it would have happened already. My guess - even if what you say is 100% correct, the pressure is never high enough to cause issues, even with pinholes.
There is US exported media that just randomly becomes popular in a specific demographic. Case in point: Adventures of Ford Fairlane, a flick with Andrew Dice Clay that got a razzie the year it came out. IIRC it got a cult following in Norway because the voice over was done by a popular radio DJ.
In Germany it's just plain illegal to have public space within the camera's field of view.
The camera must also be mounted in a way that it can't be rotated by software and can't be rotated easily by hand in a way that it is able to have public space within the field of view.
Cameras at main stations and within trains, only store their data for 24 and gets deleted afterwards afair, as long as it's not requested by some entity that a specific recording should be retained.

I usually use English to talk to Gemini, but the other day I wanted to try and find out the original band of a Siberian punk song that I have carried around in my music collection since time immemorial. Problem is the tags are all over the place in this genre and there are situations where "Foo-Bar" and "Foobar" are two completely different bands. Gemini was clearly trained on some genre forums from late 90s which are... shall I say non-PC by any stretch of the term.
In the middle of the conversation it randomly switched from English to Russian and clearly struggled to maintain the tone imposed by the built-in prompt.
Inb4: not remotely in the marine field, so a genuine question. Would it really make an impact?
Robotaxis market is much broader than the submersibles one, so the effect of consumers' irrationality would be much bigger there. I'd expect an average customer of the submarines market to do quite a bit more research on what they're getting into.
Having the whole world meming on rich dudes in submarines could plausibly make the whole industry seem less cool to people with the money to buy even a good submarine. Imagine being a rich dude with a new submarine and everybody you talk to about it snickers about you getting crushed like Stockton. Maybe you'd just buy a bigger yacht and skip the submarine, which you were probably only buying for the cool factor in the first place...
