1st lesson is to make sure that the person with the power to bypass is educated fully from top to bottom with the equipment that they control. It's not the guys fault that that actually did bypass the purging process ...nor the guy who gave the code to authorize it. Perfect example of why recertification should be mandatory every so many yrs. fault goes right to the top of the food chain on this one and shit should roll downhill a just a little bit...2) there should be a checklist in place that should be signed off on after every single step of the checklist when doing all procedures in the plant. Everything should be itemized and part 2 of checklist can not begin until part one was completed by workers and signed off on by a operator in control of the equipment the first task was done on..that's what we did and it is why I said that the place I worked it's virtually impossible for this to happen...every single thing u do in chemical plants like this (and I'm speaking from my own experience close to identical as this) we had to write out a permit for the work being done and you would call the operator on cb of that equipment and have him come to where the work is being done and you physically show him everything you are doing that's on the permit to the smallest details...we would lock any equipment valve's that only I had the key for and everyone else does it too and the operator puts a lock on it...only then will the operator sign the permit and work could begin. Even if this was done.... And I'm sure it was... It still would have happened...this tells you it's lack of retraining and recertification and not procedure itself that's at fault...this is something that they have done many many many times...and should and will continue because time is money...the perfect storm hit dead on which is virtually impossible to detect until after the fact... Which is even more of a reason to make sure that people get retrained/recertified...every year I had a few different things to get recertified to get on the grounds and work...they would not let the person who delivered our checks every week from the check company and we had to send someone to the entrance gate to meet them...16hr OSHA safety training cert is needed and the boss of our company gave the chemical companies we worked for the names of the individuals who have had and passed the OSHA safety course certification and when you pulled up u said your name and the company that you work for... definitely an oversight from the top and I can assure everyone it's impossible for that person responsible for the oversight to do anything similar again cause with that one his safety record it would cost the company that hires him a fortune for workplace insurance to have him on the site. Besides profit...there is nothing more important for chemical companies than having a clean slate with no injuries from workers onsight at the plant...no chance in hell someone else hires him..

For everyone who has gotten their undies in a bunch about toxic gas in our medical devices, calm down. For one thing, its chemical properties are what lets it kill off all the bacteria we can't avoid getting on the device, even in a clean room. I design medical devices and one of the most important things we do is figuring out exactly how much ethylene oxide (EO) to use and also testing to make sure there's no EO left after the process is over. There's actually a test called "EO residuals" we have to pass before we can market devices. The test shows any leftover gas is WAY below dangerous limits. So no fear! We've all thought about this!

About 15 years ago at about 3:30 AM, we get a call for a gas leak in a hospital. On arrival, maintenance met us saying "That alarm is going off" "Take your meters and sniff around". I questioned him if the alarm was in surgery. Well of course it is. An indignant nurse then proceeded to tell us our job, "Just go down there and read that yellow book on the wall" she says. Long story short, an evacuation occurred with a first alarm assignment, the county haz-mat team was called complete with decon lines. All because of marginal training on staff and no monitoring systems in place. BTW it was a false alarm!

Very good review of causes. Although they focus on operator training and supervisor bypass, the key element that was missing (IMO) is the LEL detection within the chamber. There should have been no way that a system could be bypassed or advanced until that detector indicated less than 25% of the LEL within the chamber. You absolutely cannot 100% predict human behavior, even given good training.

Layers of protection

Including an open flame in a process that uses C2H4O or any potentially explosive material is simply asking for disaster.

Ethylene oxide is pretty nasty stuff with a very wide flammability range, pretty much any concentration more than about 3% will burn and pretty violently. At least one source states it is used as fuel in thermobaric weapons (i.e. fuel-air explosives).That would explain why the flashback and explosion was so powerful and violent

So let me get this straight - someone designed a container for an explosive carcinogen, then attached a catalytic component with OPEN FLAMES?

Okay, for the "this stuff's in covid swabs!" people. A few molecules remaining inside the swab packaging won't hurt you. It's a gas. It doesn't form a layer that remains behind like spray paint. It's pumped in, it does it's job, it's pumped out, the tiny remainder left over filters out of the packaging over time leaving only possibly a stray molecule here and there, possibly not even enough to detect with the most advanced lab machines. This stuff's probably been used to sterilize all swabs and tongue depressors you've ever encountered in a doctor's office, unless you're old enough to predate this method entirely. You probably do more damage to your body every time you drink a bottle of beer or a can of soda, eat a hot dog, or get a sun burn. If you freaked out over every thing that's in any product that's dangerous in certain amounts you wouldn't be able to eat or drink ANYTHING. Not even water. I'm not saying nothing's dangerous, but learn how it actually works instead of freaking out over conspiracy theories and lies. You need to know what's actually dangerous or possibly dangerous. I'll give you some hints: if you want modern stuff to avoid, try carpets, mattresses, cushions, scented soaps and shampoos, and antibacterial hand soaps, for starters. Not that I avoid most of those, they're everywhere so it's not worth the effort, although not all hand soaps are antibacterial so I do okay on that one. But really. Potatoes contain "scary and dangerous" stuff that's perfectly safe as long as you aren't eating green or sprouted potatoes or enough to kill you anyway. Apples contain more formaldehyde than a vaccine. All this antivax or covid conspiracy stuff is just silly. If you're going to freak about it you may as well fear every food, drink, and other product you come in contact with because they're no safer, and in many cases less.

Not only a flame arrestor, but also redundant flammable sensors upstream that safely isolates the catalytic oxidizer while halting any more venting until the problem can be sorted out. I would guess that a 3 way valve bypass into the scrubber while isolating the remaining chambers, and gas wash injection into the piping would also be in order. It's sad to see that they relied on humans, never making mistakes, or equipment /software never malfunctioning to avoid an explosion.

Typical that they did the same job every freaking day without knowing what and why they did what they did

"safety is for life"

did it not occur to them that an open flame in a chamber used to remove explosive chemicals could be a hazard...? the extent of my chemistry knowledge is 10th grade chem but even i know that's dangerous

Probably because the oxidiser is a bad idea to begin with. Open flame near toxic gas.... nope.

I’d say the safety system tried very hard, almost perfectly designed not to poison people. With threat of self destruct if people insist on entering the room full of angry gas.

Upon further investigation CSB found the special password was......password.

How come there is an option to skip the gas washing when it is clear that you wil get an explosion when the gas cycle is skipped once the treatment gas has entered? Like once gas entered the chamber its a definite BOOM if not properly washed. This is not just an operation problem. It was a design problem too.

@@lemuelharing4137 There should always be a way to override the procedure or skip steps. Ironically, it's part of safety. It's a requirement that any step could be stopped mid-procedure (e.g. emergency stop) or skipped in this instance. Was it poor judgement to skip the ventilation step? Obviously. It caused the explosion after all, but that's why it requires the manual override and supervisor's password to confirm. The supervisor and technician were poorly trained and did not know the "science behind the methods" leading them to believe something that wasn't true. An unfortunate event.

@@anonypersona3189 Wrote a long message, batery went out, not going to rewrite. In short though, you are correct and it makes sence, could have been designed better regarding how the system runs with bypasses, rather all to scrubber than back vent with flame, cost? Extra design time, coding and accomodation of scrubber treatment rate or volume storage. But a lot of exstra design for all single shutdowns, could just train people on what happens under the assumption that training is done sufficiently for many years. It was a trade between time and increased risk of accident. Was a reasonable trade im my oppionion. Human life loss still bad. I need to design these processes. Its an tradeoff between exponential design time increases and creating a fool proof system. How safe should something be? 99%? 99.99%? 99.999999%? If your system blows up at 99.999 safety due to the greed of others, its resembles a moral predicament. Its morally easier for me to design systems for the military and the intent to kill than a system that is ment for civil use and prevention of human harm under any circumstance(worldly or concience/stentient input). Tradeoffs in a world of appliece science, statistics and the infinite scalling cost of pure science or progress towards it. Its not a qaulatative question but a quantative one that is not be required to be asked nor answered. But it is asked. An always moving line to keep track off. Thats the summary

@@lemuelharing4137 Yeah, I do agree that there should have been some more redundancy in the safety systems. Like the narrator mentioned, there should have at least been a sensor alarm to note that there was still flammable levels of gas within the system that could combust when it went to the burn chamber. That definitely seemed to be a huge oversight on the designer's side of thinking. Even if all of the procedures went according to plan, I know I would definitely want to have a sensor in place for that.

Well it's not wrong- disregard safety and you tend to end your life.

The control room windows were not shatter resistant. Have none of them seen the day after tomorrow the movie.

Partly software failure. The software should have explained the risks and consequences of bypassing the safety step, as part of the bypass process. Authoring that information should have been a key step in designing the safety bypass.

Why does a MAINTENANCE supervisor have the authority to override an Operations function? In my former business, it was the Operations supervisor's line manager (who did understand the process) who had to authorise any deviation from normal operations, and that only after a full risk assessment had been carried out.
