The first question is, what was causing the pressure to build? Physically, there is no difference between a tank sitting on its wheels on a track and a tank lying on its side on the ground. There is nothing about a tank lying on the ground that would cause pressure to build. Was there a fire around the rail cars? I've seen nothing indicating that this was the case, nor is it likely there was a wild land fire in the middle of winter in Ohio. How did they know pressure was building? Were they monitoring a pressure gauge on the tank? If so, they were close enough to put out any fire that might be threatening the tank. Furthermore, transport tanks are equipped with a pressure relief valve that would not allow pressure to build enough to burst them. Note: If the contents of a transport tank are so hazardous that they are unsafe to vent via a relief valve, additional requirements are imposed on tank strength and integrity during accidents.
Because rollovers and derailments are expected, hazardous transport tanks are designed to survive them. They are also designed with rollover protection so that fill connections are protected to remain accessible and functional in the case of these accidents. This would have allowed responders to connect to and empty the tanks into alternates such as over-the-road tanks and then hauled away. Why was this approach rejected?
Finally, these tanks are made of ductile material, typically mild carbon steel. They do not eject shrapnel when they burst. Rather, they split apart, with all material remaining contiguously attached. The tank itself might become airborne, but it would not break up into pieces. Why was the governor of Ohio told the tank would produce shrapnel?

Following the Science/Engineering is SO problematic for the preferred narative.
Just stop it or become a Meritless Garland/Fey Wray target.
Very simply. To kill white people.
Indeed.
And why was the military involved?
Oh, but it’s just so ‘overblown’. /s
Generally to mitigate the risk of a BLEVE.

Loose buttplug?
Was there a fire around the rail cars?
Yes - a hot axle resulted in a fire (red hot) that preceded the derail moment by some miles.
Otherwise, derailing can include battery by a variety of physical objects, with attending structural failures that are both expected and unexpected.
Thanks for a thought provoking article
great questions!
question authority and
think critically
Yes a BLEVE is a bad thing.
But why is intentionally breaching the tank and dumping the contents and then lighting it on fire better?
I also have to wonder; If the cars are still on their wheels and on the tracks, why couldn’t the cars have been hooked up to an engine and be pulled to a location better suited to cooling them down?
BLEVE
Why wasnt the alert system working?
They have sensors that alert on the rails.
Epic fail.
Like everything today we are to believe the sh## they spew and not ask questions. They have proved themselves a thousand times over, they are not our friends and they have the ultimate distain for us because they know WE ARE THIER BOSSES we just haven’t flexed enough to prove it to them. God have mercy on them all if we ever do
I could not believe how quickly they decided to blow it up. Didn’t those retards remember the beached whale?
But seriously, why didn’t they consult the Navy or Air Force about how to put out a fire like that? They are experts at putting out fires... I think.
The train apparently went over two detectors before the hot axle apparently seperated and perped the derailment.
NS has some ‘splainin’ to do.
After Ohio train derailment, residents are living the plot of a movie they helped make
Vinyl chloride boils at ~8 degrees F. When burned, one of the byproducts is Hydrochloric acid, which isn’t great when concentrates, but that’s preferable to vinyl chloride vapor.
That doesn’t really address the bigger question of “did they attempt to offload the chemicals?”. There was a trench that the chemicals were poured into prior to burning. If they had time to fetch heavy equipment and dig a trench, they had time to fetch a trailer that could at least handle some of the chemical. You may have to sacrifice a milk truck or two , but given the current reality, it’s worth asking if it was even considered.
Because, frankly, Idiots Abide.
I don’t know if it was the right or wrong decision. I think there were no “good” decisions because a BLEVE does appear possible from early video.
Video here - https://www.youtube.com/watch?v=dsw4ZKkLQp8
In this video you can see cars that do not appear to be on fire, but we know they were full. There are cars that are possibly full of ethyl-methyl death that are on fire or in fires. Bad day for a firefighter!
Video of a LPG BLEVE on a train from 1983 - https://www.youtube.com/watch?v=gRP5FeYenuI The rail car that exploded traveled approximately 3600’ in this incident. At the 3 minute mark in the video there is a second BLEVE.
I am reading a lot of comment here and elsewhere that either ignore this as a possibility or minimize the risks of this happening in this crash.
A BLEVE is unbelievably powerful and it is never going to “improve” a situation. Does that mean the burn-off and venting operation was the right thing? I don’t know, but I am not going to dismiss the possibility because it does not fit the “politics”.
This did not happen because of Trump, Biden, Obama, or Bush. The big railroads own our legislatures. The trains keep getting bigger and the bigger they are the more likely you have a catastrophic failure. They rolled the dice like Boeing did with their 737 issue to make a little bit more money and it bit them (the downside of capitalism perhaps) and the poor community where it happened.
I hope this mess causes some changes that will prevent another similar incident in the future.
Just my opinion, but they probably figure cheaper to emit all the hazardous material into the armosphere. Letting it seep into the ground requires much more money to abate and remove chemicals. Airborn release will dissipate over much broader area.
