Falling Through the Cracks

CSB safety video on the 2009 explosion at NDK Crystal in Belvidere, Illinois, which fatally injured a truck driver at a nearby gas station

[@yummyumsOG]

Imagine walking back to your car after going inside to pay and coming back out just to die because someone that you've never heard of, didnt inspect their crap

[@Takeshi357]

Imagine finding out your significant other or parent isn't coming home because they died because a stupid industrial accident they had absolutely nothing to do with, caused by someone not inspecting their crap.

[@Sawta]

​@@Takeshi357 And even more than that, the company that was responsible was given an excemption by state regulators! That the very designer of the equipment TOLD the company to inspect it regularly, and neither the company nor the state ever bothered. No one cared until someone died, and even then, they didn't care about the dead person, they cared about _getting blamed for it_ . It's just so far beyond absurd. "Oops! Sorry about your loved one! BTW, we're not responsible. Good luck with the funeral for whatshisface."

The NDK was about a good mile and a half from a Belvidere High School. From the front door, you can clearly see the building so it was close. I remember being in my Biology class having the day almost done. We were doing an activity when we heard a loud boom from what we assume to be from upstairs. We all thought it was some sort of shelf or a bunch of books fell till we saw a class go outside. I didn't realized how bad it was till our principle went over the intercom stating that Highway 20 is close so students must take a different path home. At that point I was confuse till the day end and I went outside to see emergency personals surrounding the building. I saw the news the night of the accident explaining that the building exploded killing one man. It was the talk for a while in school.

the acimite/acmite was actually seen as a protective feature in scientific literature. It's fairly easy to see a company going 'we have these scientific reports saying it's good, it should be fine.' Granted, that third-party inspection should have clued the lot of them in, but disregarding one bad piece of information because the rest is good is ever so common in humanity.

[@Syclone0044]

As an American, it's really awesome to hear our government's safety efforts are being freely shared and utilized worldwide. I feel proud in a rare manner.

[@acadman4322]

I've been to the kinds of meetings where managers convince themselves the Insurance study and/or government or other safety engineers recommendations are crap and do not need to be followed. The "Good Old boys" all know each other. the "Boss" is the guy they all want to please. He calls the meeting, and everyone reads the letter listing the violations and short comings of the process in question and corrections recommendations from the inspection people. "Boss Guy" then rubs the side of his nose, rocks back in his chair, looks very serious down his glasses at the "Boys" "Well? What do you guys think?" One guy- usually the best golfing pal of the "Boss"; "Hell, Bob (Seems the "Boss Guy" is always a Bob)-We know our process better than any insurance goof ball. I say we wait. to hell with those pansy assed recommendations.".: Most of the "boys" eagerly nod in agreement- what else are they supposed to do? And anyone who objects to that tone of ass kissing, who knows the existing process is dangerous and shaky at best, just keeps their mouth shut, usually studying the spots on the floor. I would invariably speak up- like the idiot i was- -; "From the Safety Department, I see no reason not to follow the recommendations. We should at least verify the insurance inspectors findings. If it makes the place safer, what do we have to lose?" Then come the guffaws. "Oh, you Safety guys- you are always such "scaredy cats"." Laughter all around. The "Bob the Boss" giving me a long look of pity, slightly wagging his head in disappointment- "Only Money, Mr. Safety man- you never think of that, do you?" Well there went my Christmas bonus. Then the decision of "wait on it" is made- in other words, do nothing!- at least until some future "sign post" like a never before attained high profit statement or a new manager comes along or a letter from some Big Wig upstairs tells them to comply or something just as stupid. And they do not forget that meeting- even though most often no minutes are kept- no letters written- no responsibility is assumed- it is like it never happened. But, of course, if the place blows up- the Boss Bob will be sure to find someone who was at the meeting to blame it all on. The general thinking is; Nothing bad has happened in all these years of operating like that and probably nothing will happen before these jokers are gone from the company anyway with their cushy profit sharing and retirement bonuses. But, months later someone would invariably say to me; - "See? That thing is still standing/hasn't blown up/killed anyone...what were you all worried about Safety Man?" Then, I get the notice that the budget for the Safety Department has been cut again- in the interest of saving expenses. That's how it was back in the old days of the 80's...and I would betcha it is still the same today.

[@notmuch_23]

How would that meeting have changed if the head of accounting, the one *everybody* listens to since that person is always looking at the bottom line, tells the Boss Man that the insurance company will no longer cover them if the company continues to do things the way they've always done? At that point, their cushy profits are suddenly at risk of disappearing in a flash. When people don't look past their own wallets, *that's* where you pose the threat to force the change.

[@acadman4322]

exactly right. It seems safety is only a consideration when it has an influence on cash in their pocket in a more positive way.

[@arbitterm]

The problem always seems to be that with safety and security, when the system works, nothing bad happens. The longer a site goes without incident, the more management starts to think all that safety and security is excessive and wasteful. Then the cuts start, and once they start they're hard to stop because they usually have no immediate negative consequences. So they keep going, like a Jenga tower, trying to see how much they can cut away while still meeting bare minimums. Then, when disaster strikes, it turns into the blame game. Someone else is always at fault, so nobody is held responsible. As far as I'm concerned, anyone who's business decisions reflect a "Profit Above All" mentality should be given no authority over safety matters. The highest ranking person in any chemical manufacturing business shouldn't be the CEO, but the god damn safety officer.

[@StCreed]

This is one reason I always make sure to keep minutes of important meetings, and mail them around after the fact. Put it in writing. They won't like it but... you're in the documented clear.

[@Indrid__Cold]

This is really interesting. I collect a lot of synthetic crystals, and the ones made with the high pressure caustic lye solution are always more perfect than the ones made with calcium carbonate at lower temperatures and pressures. Even the folks over at Sawyer Labs in Cleveland will tell you that their process grows crystals roughly half as fast as the process NDK was using. Thus, the big crystals you saw in this video would take around 300 days to grow at 350 degrees Celsius using a calcium carbonate mineralizing agent. It's interesting to note that the Chinese now grow most of the world's synthetic Quartz. I'm going to assume that their policy of extremely light regulation allows them to use the dangerous high pressure, high temperature, and highly caustic process. I have seen crystals weighing in at ten to fifteen kilograms coming out of their huge autoclave. In complete fairness to NDK management, it should be noted that a LOT of scientific literature states that the acimite coating (which is usually purposely encouraged during a "run in" crystal growth process, is widely accepted in scientific literature to protect the walls of the pressure vessels from subsequent corrosion damage. In fact, I have a bunch of "control crystals" (small crystals grown for the purpose of verifying the growth parameters) that are colored greenish brown because iron from the walls of the growth vessel is incorporated into the crystals themselves during the run-in. Check out my video on synthetic Quartz grown by the former Soviet Union. It's funny to note that a crystal scientist from Sawyer labs has several smaller pressure vessels in his garage in which he grows various beautiful Quartz crystals. I wonder if his neighbors know they are living near a bomb?

[@eliasbouhout1]

Very cool, the ASMR videos were also very fun

Confined spaces can be a pain in the arse especially when filled with lye, but what excuse is there if you're doing a shutdown every 150 days to extract your product? In any respect, to make things easier & safer for workers I would design an inspection camera rig based on spring-loaded wheels to ride up and down the tubes. I'd also suggest the insertion of a non-permeable membrane (a big sock) inside the vessels to be changed every 150 days.

[@pvtimberfaller]

Probably something more like a magnetic or dye penetrent test would be in order.

[@cvp5882]

Considering the pressure, temperature, and corrosive nature of the materials I'd say you would need dye penetration, magnetic particle, ultrasonic, AND radiography. A simple visual inspection would almost be more dangerous than not doing any inspection at all. You'd fool yourself into a false sense of security.

The vessels should be internally clad with a corrosion resistant material like hastelloy. Of course this would be expensive and by no means replace the need for proper inspections.

To have continued on as before after being served that engineering inspection report which explicitly stated the real dangers present and the annual inspection regime that was necessary in order to operate safely establishes the companies absolute contempt for public, employee and community safety! There should have been prosecutions for causing the death of that driver, the damage and injuries at the neighbouring building and the public danger! After that, the company should have been served with a compulsory winding up order, after paying compensation and fines!

[@hem1957]

legal enforcement is required for regular time bound inspection

[@shizzler7176]

Somehow I find this series of videos extremely entertaining. Especially great is the part at the beginning where they describe the chemical or material that is going to explode.

[@broden4838]

I usually pass by that factory while I drive to Chicago, and it's still looking the way it after the collapse of that reactor (Until I drove past the Belvidere Oasis in December 2015)

I'm curious... was this originally the place Western Bell invented growing quartz, and were the neighboring facilities built after the NDK location?

[@Indrid__Cold]

Matthew Trzcinski : Nope. Bell/WE sank their autoclaves in the earth. They were nowhere NEAR as prolific a producer as NDK (a Japanese Co.). Their growth chambers were about 10ft tall and maybe 12" in diameter. Their crystals were also a lot smaller.

How could someone operate giant vessels at 2000 bar/400°C, uninspected? I have been servicing 134°C/2,2 bar sterilizers for some years and they require inspection of the boilers supplying steam and change relief valves every 12 months!

[@MrEric_API]

Boilers and pressure vessels along with pressure relief valves and safety relief valves all have different inspection intervals depending on where they are located. The laws vary from areas called jurisdictions. Some entities are states or providences, some counties and cities are jurisdictions. Inspection on some equipment isn't even required annually. It it's variable....... and subject to variances, or exemptions.

Thank you so much for such an informative content!

[@WJack97224]

Fatally injured? Why not say "killed?"

[@srinithyamanavalagan1918]

Very good informative video about stress corrosion cracking .we need to more care in inspection

These USCSB videos are fantastic.

[@modman287]

Ive been binge watching these videos, and i swear every... Single... One has the same basis... Company wants to save money, so they sacrifice safety and it inevitably backfires down the road.

One of many cautionary tales for those who complain that governmental regulatory agencies are overbearing.

This proves how important inspections are.

[@brendanwood1540]

I like how you let them know that they could have prevented it and they intentionally let it happen. Not sure why employers aren't charged in criminal court. No candy asses allowed.

[@conflagrationTuesday]

Criminally neglegent, surely... The board should be charged.

As mad as I am on the behalf of the man who lost his life despite someone explicitly telling the company that this would happen, I can’t even imagine how his relatives felt when that letter was made public.

In Germany we have the TüV Organisation to prevent such hazards by law and it works very good.

Safety must be number 1 for all workers.

[@babajungLA]

I'm most shocked to learn that the vessels did not meet the ASME Pressure Vessel code. This is like Pressure Vessel 101, how did it make it past engineering? And how did no one else question why these vessels are not engineered and fabricated to meet industry standard design codes!?? Mind boggling!

[@runelee-kolhoff9471]

I drove past that building back in August 2013 when my dad, my sister and me where in a road trip to go to Chicago. I was wondering what that building was. Now I know.

[@JohnSmith-ym9fd]

I hope someone went to jail for this that is just straight up negligence.

[@tomstickland]

They had a report that clearly stated the risks but ignored it.

[@NotTheBomb]

I hope they got sued to the point of bankruptcy.

[@ShawnC.W-King]

I remember this; I was spending time with a friend up in unincorporated Belvedere at her house and after a late lunch we heard a HUGE explosion and a minor rumble was felt. It was insane... Moments later, we saw a massive smoke plume. SMH, Leave it to Illinois "regulators" to do a half-assed job to inspect subpar industrial plants 🙄

[@No_Way633]

I always wondered what happend to that building I was up and down I-90 for so long I had stopped for a while then started taking it again and it was like the building was there and gone

[@gfunk4014]

The insurance investigators predicted exactly what would happen two years later. Unbelievable!

[@ballsthatclank]

all of these videos have someone recommending something but it never gets done...why are they just recommendations?

[@MrEric_API]

The owner/ user is ultimately responsible for the vessels operation. Anyone who inspects them makes recommendations that the owner/ user may or may not follow. It's up to them to decide what to do with their equipment.

[@amberblyledge7859]

WOW. Worst up keep I have heard yet. I hope they got sued. And I don't usually hope those things, but this is ridiculous. Absoulutely, completely unjustifiable.

[@williamorr9203]
