Animation of Fire at ExxonMobil's Baton Rouge Refinery

On November 22, 2016, a fire erupted during maintenance activities at the ExxonMobil refinery in Baton Rouge, LA, severely burning four workers.

If the actual valve assembly looks anything like the animation, I would have to say that was one of the most gobsmackingly stupid accidents to ever occur.

[@dracula-dead]

I agree....you can't make this up. Must not had a great deal of pressure or just loosening would have been ugly.

[@jrow84]

Having worked with the CSB a few times, that is EXACTLY how that valve assembly looks. I’m always shocked at how accurate they are from jobs I’ve worked on

[@Syclone0044]

Jake Row I'm not even in industry whatsoever and I would bet my life on the accuracy of this animation matching the real valve. These USCSB videos are the real deal. Absolutely top notch. I've tinkered around with 3D map creation before, and I can't even imagine how much time it must take them to create each one of these animations. Literally everything you see had to be calculated and drawn out on a computer much like CAD.

[@LurkMoar101]

I work at a refinery, and every single one of these videos brings me one breath closer to no longer working at a refinery.

[@gregorymalchuk272]

Is the safety culture at your refinery as poor as it is in some of these other videos? Aging equipment, broken and leaking equipment, failure to do inspections, routine overrides of safety interlocks and alarms, and "Mickey Mouse" operators?

[@LurkMoar101]

@@gregorymalchuk272 No it isn't. In fact, HS&E constantly get hassled for being overly safety/security conscious, but I guess having no major incidents in 63 years really says something about the level of the work and planning they put in. Major shutdowns every 4 years with miniswoops in between to take care of maintenance and equipment, regular inspections, multiple failsafes and Ops that actually give a shit mean we get to come home every day. But it only takes one lapse in judgement, one mistake to change that.

Never assume how something is put together, always analyze your machinery and review your documentation before operating a task above your facility's minimum risk rating.

[@Syclone0044]

Yeah and I'm nothing but a hobbyist car mechanic. Tbh I was stunned when the thing didn't erupt as soon as they loosened/removed a few of the 4 bolts. What on earth was holding it shut after the 4 bolts were removed before they put the pipe wrench on the valve?!

[@skunkjobb]

@@Syclone0044 I suppose the pressure was not very high so rust and grime was enough to hold it together until force was applied with the wrench.

30 years ago. OH&S/EH&S was still coming more into the picture. In fact, we're still not always accepted as we should be in some businesses and even in state institutions. Lots of room for growth, but the field has always been hindered by budgets and cutting. Long-term impacts are often.

[@lettstim1474]

Agamemnon No ! Operations on it permit should have located the down stream isolation valve . It should have been locked and tagged out . Bolts removed under fresh air , checked and replaced after bracket removal . Valve tested for packing and gasket leak and put back into service . Clearly for the gas to escape the way the animation shows . The line was under pressure . Taking the screws out and not touching the plug is not the answer . You have to touch the valve . And if the bracket is suck , you'll have to bang on it to get it lose . It's and old style bracket that's been there for years . No bolts , banging , gasket leak . You have to have more command sense . Training only does so much . Everyone is not meant to work in this types of places . Facts . #UAFitter

[@celivalg]

when you work around a dangerous situation for a while, you start to loose the perception of danger, since you get more comfortable with the environment, I bet the guy wouldn't have touched them if it was his first few times, I also bet the guy was experienced... Mistakes are not reserved to the newbies, and it only takes one simple mistake to end up in a catastrophic situation

[@TomFromYoutube]

@Klaa2 well you already knew it was going to happen....

[@deltamachine2059]

Durco plug valves were made this way a 30 years ago...floserve has since changed the design so this is less likely to happen..the adapter bracket is mounted independent from the bonnet bolts...this accident happened many times with this older design. Now the new design comes equipped with a warning tag not to remove the bonnet bolts

[@Syclone0044]

Under what scenario could removing those 4 bolts possibly NOT result in a massive release?! It's hard to imagine what these 2 were thinking.

[@minimumstats9459]

i think key here is the 97% other valve assemblies being safe to unbolt. upon encountering this one, I would be like "huh? oh I guess it's these four instead" and feel like i've Solved the Problem. it wouldn't occur to me to consider the assembly as a whole if I was already used to considering it as separate components.

[@junaidbangash3969]

Thanks for animation

[@1010tesla]

at 1:18 and 1:55 the pipe wrench is applied to the valve in the wrong direction. the wrench needs to be flipped to rotate counter clockwise. it is shown correctly when the operators are holding it. also, at 1:28 the nuts appear to turn in the wrong direction to be removed from the bolts. Keep these videos coming, they are great!

[@thesciencefan5728]

The bolts are also way too long. Max 5mm. :) But, srly, I´m surprised that no one died. Isobutane isn´t that kind of friendly. Lucky them it wasn´t a pipe containing H2SO4 or H2S.

[@HobbyOrganist]

I noticed that, though it would still work it WAS backwards, and a crescent wrench would have been far more appropriate than a pipe wrench!

[@dracula-dead]

A plug valve or ball valve will turn 360 degrees in any direction with the actuator removed. It will not function as designed for flow but it will "spin" with no stops.

[@ronknight1010]

This accident should have never occurred. Just another reason all equipment must be designed with the assumption it will be operated by moron's. I build automated equipment for a living and we are constantly installing gaurding to prevent people from being able to almost intentionaly hurting themselves

[@celivalg]

[@HarryBalzak]

You guys must not work with CNC machines much, if at all. They are crazy dangerous, have bizarre and confusing UIs, and basically zero safety. I think the only reason no one at my work has been hurt or killed by the CNC I operate is because they have no idea how to work the thing so they never try.

[@Killerspieler0815]

@Aaron Provance - YES , it should be designed for people from the movie "Idiocracy" from 2006

[@MonkeyJedi99]

It is a shame that engineers have to design to the lowest human denominator. Because of those people, we no longer have lawn darts, lawnmowers have more warning stickers than technical data plates, and riding a bicycle now involves more worn safety equipment than mining.

[@obfuscated3090]

Every maintenance action should be required to have tech data SPECIFIC to the part in the techs hand and reviewed before touching anything. Good enough for aviation, good enough for industry.

[@Mrstealth93]

It honestly seemed like a odd choice to remove the entire bracket, when the gearbox could have been removed from the bracket and leaving it in place instead.

Kalel Kent Really ? So if the plug need replaced , or the seat need fixing , or even the valve needed replacing . How would you do it if you didn't remove the bolts ? Give it some thought . The bolts shouldn't have been the problem . This job minus basic safety procedures .

[@tommypetraglia4688]

Tim Lett They weren't performing maintenance on the valve. They needed to operate the valve to perform maintenance further along the stream

[@lettstim1474]

Tommy Petraglia I'm not sure what you call maintenance where your from , or work friend . But in my trade , that's exactly what they were doing . They were removing bolts and trying to remove an item . Any work on that valve on that valve live meant , the isolation valve downstream from it was suppose to be locked and tagged out .

[@norbertdx]

Should they've put the bolts back in place before trying to turn the valve?

[@gantmj]

I'm amazed they could take them out at all without the thing blowing out. They should've only taken out the two side bolts holding the gearbox to the bracket.

[@DAN007thefoxx1]

If it didnt blow just from that it seems like that would have prevented the whole thing. Im no refinery worker but I do tinker a bit with mechanical stuff from time to time. I had to replace a radiator in my car and I know that if you just open the cap while the engine is still hot, you'll blow scalding chemicals all over the place. And the manual said that if you HAVE to remove it hot, get a thick towel and gradually turn it til it hisses then remove it when it stops hissing.

[@user-tz2ti3vi6f]

[@qbasic16]

Man... some people don't seem to give a single thought during such procedures.

[@lukeward9590]

If that animation is acurte and that bracket was attach to the valve bonnet like that then it should of been pulled out of service and changed for a better safer design, also if you cannot notice that removing these bolts will make the bonnet lose then you shouldn't be working in or near any sort of refinery. Just my thoughts

[@sylviaelse5086]

"Accepted practice"? Just how often do the gear boxes fail to operate? Sounds like a problem right there.

[@Nivola1953]

At 1:36 “…but unknown to the operators….”, I’m not a mechanic but if the animation rendering of the accident is anywhere near to the actual location, you don’t need to be a mechanical engineer, to understand that those 4 bolts hold together the top part of the valve and the main body! I actually jumped in my seat when I saw the animation of the bolts being removed, even before the voice said there was a problem! What the hell happened here? How can experienced operators not realise the danger of that operation and how was this gear removal considered “standard practice” with this kind of valve installation? Only 3% of the valves, but one was on the isobutane line! WTF man this is criminal stupidity!

[@louisd.4010]

Similar accidents also occur, e.g. when workers need to remove a supported actuator but instead remove the valve stem support, which consequently flies out and releases a vapor cloud... Any bolt holding back pressure should be color coded in my opinion

[@CBeezyDSGB]

Damn all they had to do was put the bolts back in before turning the stem. I’m not sure if the animation makes it looks simpler then it was but how do you not see the pressure containing cap was bolted with the gear box

[@cleaner10399]

Gear operated valve stuck, replace gearbox. Still stuck with replacement gearbox, tag-out system, purge system then replace valve. The production delay would have been cheaper than the cost of the damage that was done. (foresight rules, hindsight sucks) Do not attempt to override the design of the setup.

[@lexluther919]

[@IrishEddie317]

Who could look at that design and not realize that the bolts were holding the whole valve assembly together?

[@teacher555555]

so who was really to blame for this accident? the two operators who mistakely removed the support bracket there by causing the chain of events or their supervisor for clearly not training these two well enough to know they could have removed the two bolts on the top and side of the support bracket and would still have been able to remove the gear box.

[@percival23]

wow, wow & wow. Any grown man or women in any field should be able to tell that those bolts are holding the top plate. And that the top plate is access to the entire pipe.

[@SuperAWaC]

these valves are stone age simple. surely it was millwrights who messed this up? they're the only ones whose modus operandi is "remove all fasteners and wrench it until something happens"

[@thesciencefan5728]

Also, if your unable to shut/open the valve with the "normal equipment" it should be time to install or new one or repair/clean the valve (if there is enough time). Sadly this handling is normal in every Refinery and most chemical site. "Use a wrench to open/close the valve" should not be a term for a supervisor.

[@SuperAWaC]

using a wrench on a sticky valve is perfectly normal. sometimes all it needs is to be turned. disassembling the valve requires bypassing the valve or shutting off the whole system

[@thesciencefan5728]

It should be enough to turn the valve via man power. But, its also depending why the valve is stuck. e.g. The pipe is normally transporting PCL3 (Phosphorus Trichloride) at ~150°C, the PCL3 should be a liquid at those temperature. In case of an shutdown (e.g. TAR) the pipes and valve needs to be cleaned, because the PCL3 will get solid. (IF the pipe isn´t dumped using N2) In this case there was no information about the stucked/hardly movable valve. They could have cleaned or change this valve. But, as I stated in my last post, lucky workers. In 6 days I´ll be working for ~4 weeks on Ineos near Dormagen (Bayer ChemPark), wish me good luck. It will be my hardest TAR. Lots of SCBA work.

[@SuperAWaC]

yes, if they had removed the valve handle properly and wrenched it open, the thing to do would to be mark it as a sticky valve for later maintenance, they were lucky indeed good luck at chempark, you should be fine. slow is safe and safe is fast.

[@wanderlustspirit4607]

[@nhzxboi]

Why are the pipe wrenches in this video always used backwards? Bad graphic.

[@Wolficefang]

In the workers' defense, the newer design was made so that removal of the vertical screws, not the higher, horizontal screws, was the proper procedure for removing the gearbox. The workers involved in the explosion removed the vertical screws, just as they would have done on 97% of the gearboxes at the facility.

[@Xclub40X]

Who needs enemies when you have employees like that"

[@HobbyOrganist]

Predicatable accident, why they didnt remove those TWO horizontal bolts instead of the FOUR vertical ones is a real mystery! The gearbox bracket was held on by 4 bolts and the gearbox by 2 bolts to the bracket, they could have removed the 2 bolts, leaving the bracket still on but maybe the guy wanted the bracket out of the way too so he didn't have to do half turns of the wrench and reposition the wrench each time because the bracket was in the way. Crazy that BOTH guys didnt figure out those 4 bolts helt the cam on TOO!

[@tommypetraglia4688]

Victorian Sculptures Excuse me to correct you but the plug valve, like a ball valve is a quarter-turn valve with no need to turn past that. Turning further than 1/4 closes the valve again. But you are correct, there was no need to remove the bracket and there shouldn't have been for this incident, just the top bolts attaching to the gear box. The screen shot at 1:20 shows this configuration with the gearbox removed, the bracket remaining in place and the wrench turned a 1/4 turn When removing anything for repair, especially in service, one must always first identity all parting lines involved with the removal. Even still, any idiot paying attention would have seen the four bolts as flange bolts holding the valve top cap and that the bracket did not need to be completely removed. They went through extra work to get themselves and everyone around them nearly killed. Clearly the common sense training of these workers is very lax and they never should have been issued the tools without supervision

[@puncheex2]

This appears to be a ball valve. A quarter turn will do.

There are lots of people putting the blame on the workers here, I understand why. But why didn't the plantowners replace all of these valves to the updated design.
