Hughes Enterprises : I don't like that there are industrial disasters where people get hurt... but I sure do love the videos showing what went wrong.

Artisan Auto Body : A most excellent use of tax money, imo. Thank you for your informative videos.

Ben Barker : Your quality keeps going up, fluid sims, lighting, shaders, mocap, etc.

Useless Duck Company : Why am i so facinated by these. And the narrator sounds like the narrator from homeworld

465maltbie : Another excellent presentation, people learn better from this format than from a flyer or bulletin. Thank you.

Liam Tarr : Who thought no labels was a good idea?

TheSpacecraftX : Really high quality animation on this one.

Dan Watt : Who LOCKS emergency breath masks......

10mintwo : yaaas my monthly dose of engineering failure autism is here

lassefar Thygesen : vape nation represent

readmorebooksidiots : The reenactment graphics are great in this one! Did your cgi person get new software?

L V : Awesome work and informative. I actually look forward to this videos.

Leo Williamson : As a Health and Safety committee Chair and former Chemical Controller at a large facility I was somewhat appalled that there were no labels on the connections, no supervision of the connection and a the operator did not ensure that the NaCl connection was not locked before leaving the area, after it's last use.

joeylawn36111 : If the operator had just waited to watch where the Driver attached that Hose instead of walking away....

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.

icannotfly : the graphics just keep getting better and better!

Winston Duong : they have stepped up their animation game 10 fold, its awesome. We need full documentaries made by these people

Gustav Derkits : Write your congressman! Trump’s budget proposes eliminating the chemical Safety Board. It costs $11 million per year , less than Trump will gain from his tax change, and it saves lives. The real reason for the proposed shutdown is that companies want to avoid the expense of safety and avoid objective accident analysis when a lawsuit occurs.

Charles Thomas : 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.

OttoVonNitro : USCSB notification squad checking in! (Better late than never)

Doxie Lain : Why in earth did the company lock their respirators up? that seems insane

tc : Operators under stress is cause of all accidents.

felix the cat : i can't get enough of these videos, is there any similar channels on youtube like this anyone can suggest?

Pedro Brito : We should be pouring buckets of funding into this agency, so much learning so little videos 😭

Luis Gil : Congrats, the quality of the video it's so great and professional as usual. Thank you for sharing it.

Harrison William : Why would this company not have the fill lines tagged out and labeled? There should be locks on each fill line with a tag stating what line it unlock and each line should have it's own separate lock.

Sean Fowler : It seems like the connections of the two chemical fill pipes should be different so there is no way to connect to the wrong fill line

PopcornMax179 : When are we gonna get a feature film?

voxelemur : My question is why the hell are dangerous chemical combinations not prevented by using different types of valves so that they don't ever mix them up? Why aren't they at least color coded?

Shami Algawzi : A great shared lesson learned, many layers of protection failed.

Atayfordays : Love the new graphics

MUHAMMAD ALIM ADHA BIN MAKHTAR - : It's seem like the Bhopal incident...

A S : why the hell would you lock up escape respirators????

juan gonzalez : Hey we have these two chemicals that are highly toxic if mixed right? What if we put both of the fill nozzles 18" apart instead of on opposite ends of the compound because reasons. Ya know these two compounds in tanks that probably have bleed valves for when they heat up and over pressure. Yeah, all of these are great ideas.

javier7high : If we're so worried about robots taking over we should start doing our jobs better lol, I mean look at these dudes, chemical transfer happens without any supervision, incorrect connection, breathing equipement locked up.

Corvid : 4:10 I seriously hope no firefighter was stupid enough to walk into a cloud of Chlorine gas wearing a fire tunic... even the pump in my tiny retained station has a couple of the old "Teletubbie" spaceman suits to be worn over your entire BA set!

David Sonnen : Wow! Yet another example of poor process design. It's good that CSB analyses these incidents and publishes their results. I'm sure that the affected industries would simply bury the information

DrHillbillyShow : In the aircraft fuel business this problem was solved decades ago. Jet fuel (kerosene) and Avgas (high octane gasoline) are distributed through hose and connector systems that CANNOT be cross connect because they will not fit together. Thus, mixing is not possible. It's that simple.

elgemin : So, if I'm the owner of a chemical plant: "Get some pipe labels." I guess also "Ensure access to safety equipment". But realistically, if it reaches Hazmat levels, do I have those on site? Or would the workers be wiser just to gtfo regardless?

Robert K : I dont understan two things. Why the operator did not wait untill the driver connect the hose even from distance. Why driver did not go for ask which hose is which. Both of them knew that they are not filling the swimming pool....

John Tucker : Conservatives want more industrial deregulation? Why, so workers and the public can be exposed to dangers and poisons like this?

Adon : which csgo map is this

felix the cat : i can't get enough of these videos, is there any similar channels on youtube like this anyone can suggest?

TheWittyGeek : The animations are those of a popular YouTube channel but the deadpan demeanor of the people screams federal government. Overall, these.videos are really interesting and I hope y'all continue to produce them.

bubba99009 : You would think a driver hauling hazardous materials would pay attention to where he is unloading. They are have to go through some kind of certification to haul this kind of stuff. Did he just pick a connection at random? The labeling could have been closer to the connection point but the lines were labeled if he cared to look. The end result could have been much worse than a chlorine gas release depending on what he decided to dump his sulfuric acid into or if the venting wasn't sufficient for the quantity of chlorine gas being produced. Many reactions with strong acids are really energetic.

Keiya : Yeesh. Ideally, the connecty bits would be keyed such that you literally can't connect the wrong things together without physically altering the connection points, but with so many different chemicals being distributed I don't think that's practical. Hmm. I suppose putting the 'fixed' connectors further apart, perhaps behind separate gates, would help. People are lazy, if you make it way easier to do the right thing they'll do it almost every time even *without* instruction.

Fred Frond : Human factors? Wtf make sure everything especially loading of liquids and even powders into the process is labeled in a chemical plant. You have labels on the washroom. Your spice rack spices are labelled this is beyond unacceptable. What would your food taste like if you had no idea of the spices you were using. Sounds like a half assed operation. Hopefully Trump does not kill this agency. Regulations too many, get rid of them.🀨

hallerd : And to think that Trump was going to defund the CSB in last year's budget proposal. smh

Jordan Gansemer : This feels like a TV show.
