[@seeker296]

@Antonio Luna ​Not just an irritant - corrosive. Chlorine gas reacts with the water in your lungs to form hydrochloric acid and hydroxide. Your lungs are not irritated - they are being dissolved into a strong acid and a strong base (Cl2 + 2H2O into 2H+ + 2Cl- + 2-OH). There is probably a neutralization reaction happening simultaneously. If so, the inside of your lungs are foaming. Lymph and blood are pouring into the area due to compromised vessels and lysed cells. It is probably more similar to drowning than anything else. Think of open blisters forming inside your lungs. In addition, your body's physiological response is to produce extreme inflammation (trying to deposit more water and buffer to control the pH of your lung fluid and remove the highly oxidative chloride ions (think: the opposite of antioxidants)). Your tracheobronchial tree is swollen shut (like in anaphylaxis) and full of fluid. tl;dr: your lungs dissolve from the inside as acid & base are formed from Cl2 + H2O ->. physiological swelling prevents passage of air, like in an anaphylactic reaction. source: 2nd year MD candidate Chlorine gas was one of the first chemical agents used in warfare. I once accidentally made a very very small quantity of Iodine gas in an organic chemistry lab. My TA immediately closed the fume hood and reprimanded me. There was a warning clearly written in the lab instructions. Any halogen (chlorine, iodine, and other members of that column) gas is extremely corrosive. In the case of iodine, purple crystals form as well, which are actually rather beautiful - just keep it away from your lungs!

Sometimes the workers running the plant were rummy from working double shifts and the procedures varied from plant to plant. Always and I mean always make sure the load will fit in the storage tank. Trace the fill line at the hook up point to the storage tank. Look for nomenclature on the lines and the tank. Ask questions all the time. Once I started the unload process I would make sure the level of the storage tank indicated it was filling by vision, sound and or feel and if that was not possible I would get a hold of the control room to verify the tank was filling. 38 years Driving trucks and I never injured myself or anyone else.

And cut him loose on the roads, he put a guy in a Honda Civic in the hospital after rear ending him after the original dump truck caused the accident.

The animation is strong with this one. One thing I noticed is the trailer, it looked like an MC407. These types of trailers have an internal hydraulic valve to shut off flow quickly if there is a problem. There are devices that breakaway and vent the pressure holding the internal valve open. One or two in the front and one at the rear. Hit them with your hand and they snap off fairly easily, shutting the internal isolation valve thus stopping the flow. It seems the driver was trying to manually shut the external valve but could no reach it, then tried to shut the internal from the other side. DOT drivers should know this, but it is an easy thing to miss when there is an emergency. Something to keep in mind if you are loading/unloading trailers. Drivers should also be in attendance during transfers per DOT regulations within 25 feet of the hose/isolation valves IIRC. Being in the cab is not in attendance and if he was watching the transfer he would have been able to stop it. There are some gaps in plant readiness for a vapor cloud. Putting some water from a fire monitor would have probably knocked down some of the gas. I don't even need to comment on the respirators being locked up. Those photos of the vapor cloud are stunning in scope. The DOT Emergency Response Guide for evacuation of the area is up to 7 miles downwind depending on conditions. Anyways, enough of my armchair quarterbacking from my soapbox. Be safe out there.

The hose got ripped off from the fill line, but also took the emergency shutoff valve with it this time, which was designed to stop the outflow of manure in case of a hose failure or a hose being ripped off. A big part of the province smelled like manure for days after around 100.000 liters of manure flowed out before operators were able to stop the outflow manually (which, due to the nature of manure and the gasses it produces was still dangerous and actually wounded one of the operators, just like in the accidents you hear about farmers being found dead in the manure-basements of their farm after having gone down into the basement and being overwhelmed by a lack of oxygen).

[@yggdrasil9039]

7:45 Having a different coupling for each chemical would be a great idea. All compatible chemicals can then share a type of coupling, so even if there is a major error, and the wrong line is chosen, at least there is no catastrophic reaction.

[@jmowreader9555]

Lessons learned, at least from where I'm sitting: Lesson 0: NEVER LOCK UP YOUR DAMN RESPIRATORS! That's like putting the fire extinguisher on the side of the gasoline tank. Lesson 1: Sign all loading connections. Print signs in English, Spanish and French. If the chemical has a common nickname, add that too; if everyone at the chemical supply company and everyone at the using company calls Stoddard solvent "Varsol," put "Varsol" on the sign. Lesson 2: Install an automated ball valve on every loading connection. Configure it so the valve is closed when de-energized; if the lights go out while you're pumping chemical into the tank, the valve will stop the loading operation instantly. Put switches in several locations, including the control room. And DON'T run them off your computer! Lesson 3: If practical, use a different loading connection for every chemical. This one might NOT be practical because the chemical supply house doesn't have a different truck for every chemical; it has one and they wash it out between loads. Lesson 4: Install a chemical release alarm. The workers in this incident discovered the release by either seeing the cloud or smelling the chlorine gas. By that time, it's probably too late.

Bit like how car wiring looms have different connectors so you can't wire them up wrong.

[@jmowreader9555]

AltairRules, if you could design your chemical receiving area like that, it would be fantastic. Alternately, you could put padlocked caps on the loading points, and attach each key to a separate tag with the name of the chemical on it. (You'd have to be careful not to get suckered into buying "fifty padlocks, one key opens them all" packages.) When the guy with the truck full of sodium hydroxide shows up, his not being able to put it in the hydrochloric acid tank because he can't get the lid off the connector will prevent huge explosions.

[@wonniewarrior]

Our farm has 4 oil tanks, connected to a manifold that leads to 1 fill point with 2 valves in tandem, 4 inlet tank valves, 4 outlet tank valves, 2 day tank transfer lines, and 4 emergency points (cappped). When it was my turn to have oil delivery day, I always double checked valves, and manually 'moved' them just enough to make sure they were either fully open or closed. Also had to make sure valves inside each boiler room had it transfer valve closed to avoid oil from overflowing day tank and flooding boiler room floor. It might have been a pain in the arse, but it only took 1 leak to reinforce checking and double checking. We also numbered our tanks with large paint so driver knew which 1 we were filling. 30,000 litres of oil in a paddock was something we could not risk ever, and we got damn lucky 2 people knew it intimately, and another person who filled in knew it basic but was trained to call us if problem or unusual. Would rather tell that person to leave everything shut off and I drive 30 minutes in just to make sure (on day off) than a disaster.

I really like these videos, and while I dont know if they are actually meant for the general public, or more for people involved in this area of industry, but I really appreciate the time taken to create these videos, much simpler than reading through sometimes hundreds of pages of text from a report or investigation etc, especially for someone like me that has limited insight yet a great (although sporadic) interest in this sort of safety (or where it fails, rather), and should I want to delve further, I still can. Also, since these are created for the sake of the actual subject in mind, they are much more condensed and relevant than many tv-shows about X/Y/Z disaster. In any case, thank you.

[@TheCarson116]

Well, it's unfortunate that another incident like this had to happen, just thank God no one was killed. I have to agree that the operator should have been on scene during the filling, to make sure the correct fill line was used and the filling was done properly, along with all chemical facilities across the nation should have automatic valves between EVERY piece of equipment and piping, in case of an accident like this one. In addition those valves (and by extension all valves at every chemical plant across the US) should have been clearly marked so the driver knew which was which. Although I'm sort of surprised that while the CSB covered most of the problems that lead to the incident both in the animation itself and in the investigation breakdown after, the one thing they did not mention was that emergency respirator cabinets should be unlocked at all times. After all, someone's life may depend on them. It's also interesting to see actual brand names now(excluding the names of the companies which were involved/responsible for the incident) in the CSB's animations, like the Mack truck in this animation.

[@TheCarson116]

First of all, calm down, accidents happen, we all make mistakes, the important thing is no one was killed. Second, yeah, I recall seeing a KAMAZ truck in their phosgene release video, very odd why they would use a RUSSIAN truck for an animation set in the US, unless that was the only truck model they had/could find at the time.

[@BillSchillaci]

There was more than one mistake here. But the worst was the MGPI operator just walking away -- assuming that's what really happened. That seems utterly irresponsible.

[@Nareimooncatt]

TheBrodsterBoy I drive tankers, including sulfuric acid. Most trucks have a PTO air compressor to pressurize the trailer, which then pushes the product out. There is no "tank pump" for the storage tank that facilitates unloading. I have a few questions about this as well, because the PTO should have been able to be shut off from inside the cab before he ever got out. This alone would slow and eventually halt the transfer as the trailer lost pressure. If he didn't do this, then perhaps he used the plant's air supply. This is also possible to pressurize the trailer, and would explain why he couldn't get to it to shut it off, depending on where that valve was. Fyi, this is one reason why I prefer using my truck's compressor. But if his trailer was like what I use, there would've been an emergency shutoff valve on the nose of the trailer on the divers side (in addition to the two valves at the rear). So why he wasn't able to reach that is baffling me unless the cloud was already enveloping the cab and affecting him as soon as he opened the door. He also should've verified with the plant operator which pipe to connect to. That way he would've known even after the plant operator left. But this doesn't seem to be a video meant to dive into every minute detail, and is a broad overview that hits the most important points. I suspect there are other factors from both the plant and the driver that aren't included here.
