Without 'blood' the NTSB rarely gets involved.

tree68 Euclid I think that is correct. Somehow the process of shipping has to be made safer in order to handle this material. That may true with other types of hazmat as well. The fact there there hasn't been a plethora of similar incidents involving this chemical speaks to said chemical having been shipped before with no problems. Assuming that reports of the car being humped are correct, this seems to be the smoking gun. If cars/containers carrying it have been humped without incident in the past, it would seem that the railroads handling it have been lucky so far. This time caught up with them. OTOH, if the railroads normally take "Do Not Hump" at face value and don't hump the cars, it would seem that they've been handling it pretty safely in the past. No need for knee jerk reactions. The railroads handle thousands of movements of hazmat daily, with danged few incidents. In fact, incidents such as this one are quite rare. Most of the hazmat incidents we hear of are secondary to some other issue - like the axle at East Palestine.

EuclidAxles will always break or burn off, but if a lot of hazmat explodes and burns as a result, I would not dismiss that as “secondary” just because it was caused by a broken axle, which came first.
As devastating as a hazmat incident is, it's still secondary to whatever caused the accident in the first place. The primary cause of the incident is the mechanical failure, without which the hazmat incident would not have occurred.
I would opine the primary concern of the investigators at East Palestine was not the hazmat - it was the burned axle and the lack of detection and action that resulted in the incident.

I think the investigation will focus on the following factors:
1. How was the commodity packed?
2. How was the commodity secured in the container by the shipper knowing how dangerous it is?
3. Which UP employee authorized the car to be sent over the hump and why did he do so when the container was marked DO NOT HUMP?
4. Why did'nt the hump yard master prevent the car from going over the hump?
CSSHEGEWISCH NTSB investigates a lot more than railroad accidents, aviation issues take up much of their time and manpower.
The kind of investigating that the NTSB does roughly (ahem) falls in the tracks of what the Civil Aeronautics Board was doing for airliner accidents. The ICC did investigate RR accidents but not to the level of detail that the CAB did with fatal airliner accidents, e.g. re-assembling the airframe from bits and pieces of debris.

EuclidHowever, the point you obviously intend to make by the use of the word “secondary” is the part of the definition meaning “less important than.” You appear to be making that point simply to downplay the disaster.
Don't humor yourself. That is NOT what I meant.
I'd explain it, but you probably wouldn't get it.
I'll probably get dinged for that, but it had to be said.
There's an article from the North Platte Bulletin newspaper that quotes one of the public officials saying the car went over the hump at 530am, the source of that info isn't given. One of the pictures, if captioned properly, shows that car and some other intermodal cars towards the west end of one of the sub yards within the complex. The flow of both humps goes west to east. It's not in one of the hump bowl tracks, so if humped it must have been moved.
Looking at a map of Bailey Yard, it's hard to place the car's location. I almost think it could be the west end of the eastbound receiving yard, but that doesn't look quite right either. The way the tracks are arranged, with car men's roads between groups of 2 tracks suggest one of the departure yards, but with those I think there should be more tracks in the background.
There are links available, but I'm posting this from my phone. The NP Bulletin article was from 9/18, there is Bailey Yard map available on the Trains website. That map is from about 2010.
Until a definite statement from a UP official or FRA report says the car went over the hump, I'll be skeptical. I wonder if it was in a block of IM in a manifest and the rest of the manifest cars where humped that morning.
The article, has I think others have too, state that the local responders had to talk to people in Cheyenne to find out the contents. This is perplexing. It seems like they were going through channels instead of talking to someone in NP.
I'm guessing the first report of the car involved being batteries was someone looking at a track list and noticing a container with lithium ion batteries and thinking, given experiences with those-an autorack of Teslas went up in flame at NP, thought those were involved. They may have seen the listing of the acid but like most of us, probably didn't have clue towards it's volatility.
Given it's bad reaction with seemingly almost everything, it's surprising there isn't more incidents. Just using it in a manufacturing process, let alone transport would seem problematic.

Peracholric acid has a reportable quantity of anything meaning if you have an ounce of this stuff you'd better have corrosive placards in place. It loves to react with anything organic or that has carbonates. It's considered more dangerous than red nitric acid will explosive react with wood metal glass and certain plastics. If being shipped in liquid then it requires Ceramic lined containers held in suspension in water. We sometimes haul it but if we do the rate we charge well let's just say our customers don't ask us to move it very often. We start the rate at 20 a mile for us to move it.

Thanks for that information. About the only thing I have found on transporting Perchloric acid deals with transporting it across a room in tiny quantities. So I am curious about the part of your comment that I have highlighted in blue. It sounds like a way to cushion the containers holding the acid. But it raises questions about how that is actually done, and the exact reason behind it. The shipment that ignited/detonated in the Bailey Yard was 50 drums holding 55 gallons each.
What else can you tell us about the shipping method you mentioned?
How we require it to be shipped is sealed ceramic containers we require a double o rings silicone seal secondary sealed on the outside with wax then it's placed inside a framework of the water-filled container. We basically nest the acid container inside another container full of water. We've never had a release of it that was undesired. But when we're moving it we'll have a team on the truck. This stuff is to freaking nasty to play with and we routinely play with the worst of the worst in corrosive world. So if we're scared to mess with this crap I don't really want it messed around with.
This info below is NOT to explain fully or minimize the perchloric explosion. As Jeff has said, we need a lot more information.
Upon research, I discovered .....but aqueous solutions up to approximately 70% by weight at room temperature are generally safe.
Thus the comment about food/drugs may be applicable, when mentioned in the Trains News article several days ago. After all, look at almost all your medicine.... it contains hydrochloric acid. HCl (often in the name of the medicine). endmrw0925231320

This is supposed to be the standard used for this. However some will call them less than scrupulous carriers won't use them. They think that it isn't that bad or they won't have trouble. They literally are playing with people's lives with how they treat hazmat sometimes. But until the fmcsa or other alphabet agencies that regulate how stuff like this is shipped step up accidents like what happened in North Platte will happen.
