The guys undid the wrong bolts. If they'd done the right ones, there would have been no danger. They didn't realize that this one had a different design. It wasn't an issue of them being made to do something they thought was dangerous. The action itself had not been thoroughly vetted by a safety team.

I left a job because of lack of safety awareness. They had an extreme turnover rate for EHS managers (employee safety and health). Any EHS manger that identified safety issues and recommended changes (that usually cost time and money), were quickly run off. After a co-worker was seriously injured during a fire/small explosion due to a machine being set with the wrong parameters due to a fault in the old timing equipment. It was not a fault of any operator. This was clearly evident to all who knew how this process worked. The EHS manager at the time was instructed to find an employee, any employee possible that he could put the blame on. This would keep them from having to update the equipment, and blame it on operater error, and possibly avoid spending a lot of money and downtime. He refused. This was the last straw for him, me, and several others. 2 years after I left, the same incident occured, but this time it caused a much larger fire, and much more damage. There were a few injured. OSHA got involved, and the fines were massive. I have the safety first mentality. To many, that it just a catch phrase. Take it seriously. I have seen way to many accidents that could have easily been prevented if someone had spoken up about a safety issue, or followed proper guidelines.

This is a prime example of a case where the old design should have been adequately safe, but required to field personnel to pay attention, which is why the newer design came to be. No matter how much we try, we cannot design everything to be completely fool-proof, because there's always a bigger fool out in the wild. We do however try to make things as user friendly as possible, and the fundamental design lesson from this incident is to not use pressure containing features to support less process critical features. The operational lessons are to select your people for smarts, don't over-stress or over fatigue them, and make it abundantly clear that if a job is not going as smoothly as it should, to stop and call for help... and lay down the law on people who give others a hard time for reaching out for help.

But when I think about it, all the equipment, that I ever worked with had a meter close to the flange bolts somewhere - and when you see the pressure indicator, the brain immediatelly tells you not to touch the bolts - and this was not the case in this accident. From my point of view - I would use different style of bolts for all the structural elements, which you are not suposed to touch, when performing a normal maintenance. Also, using some water-proof housing for the gearbox would most definitelly help - the whole problem was created by rusted equipment in the first place...

A way the older valves could have been modified to make them a bit safer would be to drill a small extra hole through the support bracket base, and the top and topcap faceplates to run a padlock through.

These incidents always seem to boil down to "Nobody was responsible for ensuring safe practices" and in my experience the reason is always the same...when safety procedures are strictly enforced and adhered to, there are usually few to no incidents. This lack of incidents leads management to presume that such strict protocols must be excessive and thus the long backsliding on safety begins, since doing things at the height of safety is time consuming and thus expensive. The sad fact is managers are seduced into thinking "If nothing has happened so far, everything must be fine". Add in elements like fatigue, inexperience, and poor training and you have a recipe for a disaster cocktail.

Great content. One small minutia, I scrolled the comments and think the video properly addressed 99% of it, at 7:00 however they mention addressing workers discussing difficulties removing the gearboxes as a potential avenue for disaster mitigation. While this is correct I don't believe this would have mattered as the employees did NOT have difficulties removing the gearboxes, nor did the one who were not properly trained on recognizing the procedure for the old valve have knowledge of their errors. It's basically saying workers would've self-identified hidden future knowledge to forewarn the company. Now the investigation may have revealed former complaints or incidents which would change the above, however it was not mentioned in the video.

If this animation is correct, well, I don’t know what to say, except that the workers were ridiculously incompetent. The bolts obviously went thru the entire valve cap assembly.

Looking at the valve support fixture it looks like on both old and new versions the gearbox can be removed by removing the top bolts completely eliminating the need to touch the top cap.

The pipe wrenches are facing the wrong way when used to open the valves. That's not how you orient them. The jaws should face into the direction of travel, not away. You have to wonder at the lack of awareness by the individuals opening the valve not to realize that those bolts held the top cap on. It's obvious when you look at it.

If they had been dealing with the newer versions where you removed the bracket with the gearbox. Then you might be inclined to remove the bracket for the older ones as well. But they obviusly didn't give this much thought. Maybe fixing the gear required the bracket(alignment and so forth). Maybe they've seen it being done that way by others, different being they replaced the 4 bolts. When you are going through the motions its easy to miss the glaring obvious.

You can clearly see it's a right angle bracket that's also bolted from the vertical stroke, why on earth would you not just remove those bolts instead of the ones holding the pressure valve together

0:57 Management of safety is critical to the protection of workers, but sadly it seems that it's often treated mainly as a cost, reducing company profits.

why didn't they leave the four bolts on the main valve and remove gear box at the correct to removal safe side on that flange connection?

theoreticataly, they could put them back and safely open the valve, but once the bolts were back, they would not be able to put the gearbox back. it is possible to remove GB, open valve and put GB back only with newer model where the gearbox is not connected to the top cap

I MISSED YOU GUYS

Why didn't they bolt the valve back after removal of gearbox but before wrenching the axle? Just some common sense!

It's clear why the old design would appear reasonable, as it utilizes existing mounting hardware without requiring the pipes to be changed. Likewise the newer design is also reasonable as it avoids reusing the pressure bolts for the mounting bracket, to avoid confusion on which bolts to remove. Having both sets in the same facility especially with incomplete training is the problem here. If you only knew how to remove the newer design, the older design would be confusing and it would be likely anyone would assume the pressure bolts were the proper ones to remove, if they were not aware of the true function of those bolts and the top plate.

The refinery is a ship. The captain is responsible for everything. At the refinery it is management. Hire the first guy that passes the drug test. On the job training, the old guys train the new guys. 3% of the valves different without markings or warnings Worker comp expenses are cheap compared to one day's profits. Particularly TX and LA.

How do you not see that removing the 4 bolts is not a good idea?

Yeah, because the business has no responsibility whatsoever to train workers. Why should employers bother training workers? If they weren’t bad workers then they would already know how to be safe! If a worker gets hurt it means they’re a bad worker that should be let go, which I’m absolutely certain is exactly what happens to everybody that falls into the Exxon meat grinder.

Thanks for this information

If the purpose was change the pump, the last valve beforer that shoud be was close with an open drain between them , why they ere attemped open the valve? to drain the pipe completely? it was not clear. Can you enswere?

I just don't know how anyone could possibly not realize that those bolts were holding the top plate, which is the lid to an open pipe. That is pure insanity.

Same guy that uses a pipe wrench backwards. Maybe?

This accident happened because the guys weren't paying attention to how the valve worked, or didn't understand how it worked. Perhaps they also didn't know that isobutane was flammable, or that it would escape if they took the valve apart. There is a limit to how far one can go to combat ignorance.

Please study the recent accident at DSM resins in Augusta Georgia

a large percentage of the workers there got their jobs being related or associated to someone else that works for Exxon-no degrees or training before hand

Agreed, even the most basic mechanic should be able to look at that and see it's going to be a problem.

I wonder if that was as easy to spot in the actual valve. Seems bloody obvious that that was a bad way to remove the gearbox, especially when you could loosen only 2 bolts to do it right.

I’ve been around tons of the 2 types of valves mentioned in this video. It’s pretty obvious which ones you don’t want to go unbolting on a live line and which ones you can. It was either pure stupidity or ignorance as to why the person/s decided to completely unbolt the valve bonnet.

Two of the contractors settled 16 hours ago as of the writing of this post, i.e 2019-11-04.

I hate how they show the pipe wrench being used BACKWARDS. This is a safety video and you guys can't even properly demonstrate basic tool use? On another note, it is called a valve bonnet not a top cap. As a pipefitter, I completely agree that removing the bolts from a valve bonnet that is under pressure is a terribly dangerous practice. Unfortunately I'm not surprised that someone was injured/killed.

A silver sharpie with some notations wouldve been good Alternately if they remembered to put the bolts back in as well But why was there no procedure to consider more maintenance when the unit failed?

Why not use a stud/nut/bracket/nut combo? It would be cheaper than replacing all the old valves. Or is it that the old valves were so unwieldy/stubborn that a large wheel and worm gearbox couldn't turn them?

I was curious why they took off the whole bracket instead of the 2 bolts holding the gear box to the bracket. Looking at the picture did they think it was too corroded to do so?

How can you not see what bolts to remove? Holy smokes.

Inspite of safe operating procedures and good written practices, how could a mechanical device provided with single system of connection for both valve and top bracket and how could that worker operate a valve leaving the top bracket open😳 it’s purely stupidity.

I worked in quite a few refineries and chemical plants before retirement and looking back now I'm like what was I thinking. Grain elevators , ship yards, refineries and chem plants are extremely dangerous work environments and I wouldn't recommend working at any of them especially refineries and chemical plants .

Very interesting how someone could make such a mistake. What could have confused the technicians is the top doesn't get pressure until the valve opens a little, so they thought the bolts were just mounting bolts.

Jeez man. How can you be so negligent to the pressure systems when opening the system.

Are they slow? They did not see when they took the bolts out there was nothing holding the top on to the pipe? Just a gasket between two pieces of metal. I mean you don’t have to be an engineer to see if you take the bolts out there’s nothing holding that valve to the plate or pipe
