[@lpconserv6074]

Wow... Shocking to read of this. I was the operating engineer in that plant up into the late 90's when it was Quantum Chemical and before Lyondell bought it. I have had my hand on that valve. It was a zirconium cast valve and the whole time I was there, we did everything imaginable to NOT touch that one or the one next to it also zirconium. They are right, the plug valves used are a quite old and standard design, although cast of a new and amazing material. As the video played out, I saw the animated guy reach behind the actuator assembly. They got it right that there are studs holding that plug cover plate to the valve body. Those should have never been touched. I have seen that actuator removed in a previous plant outage. It has been sticking to that shaft every time. It has corrosion on the shaft from a tiny amount of leakage through the top shaft seal for years. But all would have been fine had they not touched those 6 stud bolts holding that cap down. For the undergrad below that is trying to learn what these valves (and really most all common valves in use) Try to find a Crane valve book from ancient times.... about the year I was born. Ebay has been my source. I have 4 excellent copies of the 1953 version on my shelf at the moment and one 1960 version. I have given away 7 or 8 of these to some very worthy engineers in the years to guys I thought would use them. Had these guys had one, there are cutaway photos of these and almost all common valves you will come across. Mine are not for sale, as I have at least 2 earmarked for a couple of really good engineers that need them. But the USCSB is right, these valves could be made to be less likely to be opened by accident here. Yes, dying from the reactor contents here would be a particularly bad way to go. Vile stuff in that reactor, along with a LOT of dissolved carbon monoxide in pure form.

[@gmaxwell]

Do you think it's possible that the workers had experience with *installing* other actuator designs where the actuator has a mounting plate that is captured by the valve cover bolts? it wouldn't be a correct procedure to remove the valve cover to remove those actuators either, but someone could just think they were supposed to reverse the install procedure.

[@Jonnyg325]

Why does the actuator have to be removed to ensure the valve stays shut, isn't there a setting for it to keep the valve shut without removal?

[@lpconserv6074]

@@gmaxwell Yes, when I was there, this was a top critical part and ONLY a designated supervisor and his best two mechanics were allowed to touch it. And we avoided touching it at any opportunity. Unfortunately, in todays world of cheapest labor standards, it will be obvious to the experienced plant people that these guys had no idea how that valve was assembled.

[@lpconserv6074]

@@Jonnyg325 The rule is set up to prevent just this occurrence. It is reoffered to as a "lock out tag out procedure." It takes the whole complex manager to get this rule modified or changed. We looked at this valve to modify it for a locking pin to be added so it could be mechanically prevented from rotating. It was deemed to be impractical due to the Zirconium material. The primary shaft would need to be drilled and a pin made with stops so it would not be able to turn. But zirconium being drilled, was possible ( though highly unlikely) to get hot enough to catch on fire itself. So it was abandoned. My input was that this valve requires so much torque to open and close that we were worried that if someone re-connected the pneumatic air to it even if with a utility hose, the unsuspecting mechanic would likely have enough force to break the pin and activate the valve. It is a difficult thing with plug valves. people struggle with this in many places. The way I dealt with it while there is put in a rule with the supervisors in the plant, that either a supervisor or myself would be standing on deck with this valve if anyone was going to work around it. Many of the mechanics are not intimately familiar with the inner workings of these valves. Only ever had 2 shutdowns while I was there and one did not require this valve to be touched. The other one, we simply removed the orange actuator (it was actually orange in real life in the field) and as always found the coupling to be jammed on. We finally freed it up and got it off, but with at least a full shift trying to make it release. Several times we needed to remind the mechanics NOT to touch any of the 6 bolts holding that cover on.

[@lpconserv6074]

@@Jonnyg325 The only "Setting" is the removal of the actuator air supply. However the "rules of lock out - tag out" do not allow this method of making certain the valve would not rotate. Seems obvious that it would not move , but the rules push for mechanical stops to be in place to prevent rotation of that shaft. Seems a bit much, but remember those 3 guys up there almost certainly have with them a pipe wrench. That alone would turn the valve to the open position. I understand it would be stupid to do that. But pulling not one but SIX cap bolts is what actually killed them.

[@jlo7770]

They say every "accident" are preventable. I've argued ad nauseum with "teachers" that not all accidents are 100% preventable. It seems "educated" people are taught that nothing happens randomly. I do agree most accidents I've seen are typically preventable (I work in oilfield on rigs) I've seen some wicked incidents but it's annoying to have some person whose never worked a day in their life tell you something elwas preventable, "yeah that catastrophic failure of a brand new rope wire that dropped 95,000lbs was 100% preventable and your fault".. ahh yes thee old "you should have inspected it and noticed it was going to fail" method of avoiding a lawsuit and trying to blame the employees instead of taking responsibility for your purchase of Chinese shit that almost killed 3 people exscuse. Those people got mad when I said "if I was that good at being a psychic I sure as fuck wouldn't be working on rigs". I think "safety" is looked at the wrong way, instead of pointing fingers and blaming the individual, saying their at fault, safety should be looked at from the perspective of teaching people how to recognize risk and how to situate themselves in better positions to avoid injury. If you like "safety" lessons learned videos there's a channel called "Brick Immortar" that does a lot of maritime accidents but also some other stuff that's extremely well put together and gives you the facts and how they could have reacted differently to avoid situations when available, and what people did right. Very interesting channel if you're into this type of "safety" content

What makes this even more tragic is the acutator was being removed to allow for valve lockout. These workers were killed/injured performing a job that was intended to make another job safer. The risk assessment of repairing the leak was properly done, but the risk assesment of the task needed to complete the required work for that leak repair was lacking. The same as an electrician getting blown up by an arc flash while racking out a disconnect to de-energize something for repair.

[@benjaminhampel8640]

What makes it even worse is that the valve actuator did not have to be removed in the first place. Usually, only the power supply to the actuator is interrupted when it is closed, so that it cannot be operated.

One of the workers explained his reasoning for removing the pressure-retaining nuts. He told the CSB they had to remove the interior fasteners because “…it’s all connected. As [the actuator] sits up there, it’s all connected to one another.” This worker did not seem to understand that the interior fasteners were pressure-retaining and should not have been removed.

[@benjaminhampel8640]

If it was really necessary to remove the pressure retaining screws to remove the actuator, which I doubt, then the actuator should not have been removed under any circumstances. But that would not have been necessary to secure the valve so that it would not be opened accidentally. Usually you disconnect the power supply to the actuator when it is closed to prevent it from being opened accidentally.

Here is my theory on why they removed those nuts: On *some* actuators (see page 20 of the report) the actuator is installed by putting a plate under those nuts. You still shouldn't remove them when removing the actuator, there are other nuts for doing that.... but if you had only ever *installed* new systems using that style plate you might think that the correct way to remove the actuator was to reverse the install procedure. This is also consistent with the worker's explanation for their actions.

[@MoritzvonSchweinitz]

I'm a big fan of good "error culture". Errors happen, and we have to fix the processes and systems to reduce the likelihood of them occurring. I think it's fascinating how these CSB videos rarely, If ever, blame the workers for the accidents. It's very similar to the investigations and recommendations after an aviation mishap. Don't blame the person. Blame and fix the system that allowed the person to commit an error. Thankfully, even the medical sector is finally starting to improve their error culture.

[@kosannicholas2842]

I tried to push this approach through as much as I could in my previous manufacturing job while on the safety committee. Even beyond that, when approached by management to isolate quality issues (since I was often the most knowledgeable of our entire production chain in my dept), I always made sure my answers indicated policy & procedure problems, so long as there was no evidence procedures had not been followed. Most of my direct managers must have appreciated that, because they kept coming back to me for advice/direction on quality/safety investigations. I think it's always important approach problems that way.

[@complainer406]

I wish this sort of thinking would get applied to car accidents. It's always about liability and incompetence instead of road design, vehicle safety requirements and licensing

[@Jordan-dt6qx]

That's the key! When writing policy and procedures to be done by thousands of people over millions of collective work years, you have to account for human error. Its guaranteed to happen. Levels of redundancy, thinking past stage one, and never being in a position where any worker is ever one mistake away from injury. When I was a young guy learning to fly, the instructor gave me a piece of flying advice that I apply in many places in my life. "Always be at least 2 mistakes from the ground".

[@voyagerwitch]

if you blame individual people, especially people who have died, there is no recommendation to be made. it's saying everything can just keep going as normal because all of the problems have been purged. this is the only possible way.

I think they missed one - design plug valves so that they do not need their actuators removed in order to lock them in the closed position.

[@jonathan1427]

I think it should be a feature of the actuator assembly. At my plant we always have a manual valve in line with any automatic valve on process fluid piping.

[@maoiljitschguevara]

Could you maybe enlighten us why in this case there might have been a need to remove the actuator at all? Can't one just tell the actuator to close the valve?

[@bevanjarman7472]

​@@maoiljitschguevara It is probably ironically for safety purposes. If you remove the actuator, it can't accidentally open the valve. So once the valve is closed, it stays closed while they are working on it.

Or close and lock the air supply powering the actuator.

It's similar to what destroyed Piper Alpha. Maintenance workers removed a pump for servicing but the paperwork was not seen by the next shift. The workers started the pump not knowing it was down for maintenance. The maintenance crew had only put a temporary seal on the pump so it leaked and the whole rig went up.

That's a LOTO issue. This is workers without relevant training or knowledge messing up a task that's routine and low risk when a qualified worker is performing it.

Before I started following chemistry, it had never occurred to me that acetic acid could be dangerous - after all, it's in vinegar, and we use that all the time. But, of course, if it's concentrated enough, acetic acid could absolutely be dangerous.

[@empireoflizards]

When using certain silicone sealants, the odor is described as 'acetic acid'. Having used it, the fumes do have an intense burning sour smell when inhaled and is considered toxic in accumulated amounts.

[@stephanzielinski7922]

And according to the report at www.csb.gov/lyondellbasell-la-porte-fatal-chemical-release-/ , it was at 238 °F. (!) (There was also water and methyl iodide in the mix, but those would have vaporized at that temperature and standard pressure.)

[@adrianhenle]

It's worth pointing out that concentrated acetic acid is also flammable, which is obviously not a property of vinegar. It's tempting to compare chemicals to the common products in which we encounter them, but the pure stuff needs to be considered in its own proper context. 10 % (vinegar) and concentrated (glacial) acetic acid have different safety data sheets for a reason!

[@MonkeyJedi99]

Chemistry is interesting indeed. A block of sodium is so reactive, it will exothermically break apart water, possibly leading to a hydrogen fire/explosion. Chlorine gas is so reactive, it will kill you if inhaled, and may do so with enough skin contact. Put the two together, and it's one of the more crucial components of our bodies, one we can't live without.

[@michaelmerritt7406]

All chemicals are dangerous. Acetic acid can easily cause chemical burns, and acid vapors are hazardous.

This is a scary one because I have started disassembling vales myself that I didn't have manuals for myself, albeit on air or hydraulic systems that can't usually kill you. These poor contractors where in a situation where I'm sure they thought their mechanical knowledge could overcome the lack of a valve removal procedure. We can all learn alot of lessons about making sure you know the entire process before starting and not being afraid to stop if there's inadequate materials. RIP to these workers.

[@Awegner176]

Coming from oil and gas, it's pretty alarming to me that these people were working on a non "blocked-in" valve on the bottom of a full vessel. When possible, it's typical to install control and isolation valves with options to either blind off or manually isolate with secondary valves to make maintenance tasks safe and efficient. This is a failure on the design side first and foremost.
