I hear that, but it would have been going off continuously anyway, negating it's usefulness as the staff was clearly OK with bearing threshold levels...thats common since many alarm systems are set below necessary thresholds-some ridiculously so, I assume for liability reasons (maybe not this one, but people judge by overall experience).

because sometimes you can make an area safe while you make repairs but the alarm still sounds until the leak s repaired. the fire department should be the only ones with access to the silence button.

[@deeznoots6241]

So that you can fix the problem without it blaring at you, the idea being that you only silence the alarm when you actually have a plan to fix the problem.

[@brandonnewman8135]

One reason would be if it's a false alarm because of wiring issues or testing. or if your already aware and working on the issue not much point in keeping the loud ass thing on. they however did it in the worst case possible. they should have at least been monitoring the pressure and should have had personal detection devices they also probably should have worn their PPE and had a crew of fire department outside to keep in touch with them which is what you're supposed to do if you are entering any environments that possible contain hazardous gasses.

As someone who worked at an ice rink and was around ammonia, i cannot imagine in any way shape or form how they would even consider trying to restart the compressor. i remember when we had a leak it was around 10 ppm, and it was unbearable to be around. The first reading they got was 300 ppm.... that is insane.

Alarms are 100% safe, especially in silent mode...

[@vacciniumaugustifolium1420]

if you shut it down, you must be prepared like it was on, even if there is no immediate risk.

[@SenileOtaku]

I can understand silencing the alarm, because the noise could be severely distracting while trying to solve the situation. That doesn't mean to act as if it's no longer a problem, though. continue to behave as if there's still a danger until such time as you can be assured it isn't. And the obvious red flag should have been the levels the ammonia went to in the first place. If you have the alarm set to 35, and it reaches 300, that's a sign there has been a critical failure. I wouldn't have considered the ice itself to be safe either (not knowing just how far or even where the leakage was).

[@beefchicken]

Given the mode of failure, the alarm wouldn’t have helped them one bit.

[@Pikmin012]

If you know ammonia levels are currently safe and the alarm is still not shutting off, it will do you zero(0) good. Should ammonia levels rise again, the alarm will still be screaming like it was all day, and nobody will know.

[@mangore623]

They silenced the alarms, and restarted the plant...to save the ice. Unbelievable. The outcome was a fait accompli with stupidity of this magnitude. "The decision to operate the leaking chiller is pivotal in the development of the incident," reads the report. "Once the leaking chiller was put back into operation, additional actions and decisions were a response to cascading failures and were beyond the scope of training and situational awareness of those involved." The regular life expectancy of a chiller is 20 to 25 years. The Fernie chiller was 31 years old when it failed.

[@hajjdawood]

Not to mention who knows how much ammonia was leeching into the ice etc.

[@RootedHat]

Money talks, people die. Another day, another dollar.

[@acebulf]

The ice is never in contact even with the brine that the ammonia leaked into. Brine is circulated through pipes built into the concrete structure that the ice is built onto.

[@mfree80286]

The silenced alarms would only be a factor for getting an emergency response after the second incident (to warn anyone coming in that ammonia was present), and/or warning that response and anyone else arriving later that there's an ammonia leak. The three crew that died in there, that alarm would be incidental to them because they were hit with a sudden release and not an accumulated gaseous leak. I am surprised that there was a) nobody watching any of the pressure gauges on the chiller system, or b) no automatic pressure release mechanisms. But wasn't there a saline expansion tank? Was there a check valve working against a flow valve here, were the wrong set of valves closed during the emergency? If everything was sealed solid because of the ammonia content in the brine, why was anyone allowed in the building at all until it was stabilized? So yeah, you have it.. nobody understood the system, theory, risks, operation, and hazards well enough to manage the situation at all.

[@user46346bdtgry]

You should’ve called the firefighters to be back for the restartment because they were able to stop the ammonia pipe explosion but were told to leave because of their price

[@rwe52496]

This is why communication and having backup is so important. I can’t believe the system was restarted to save the ice in the rinks, when they could have easily known that was going to spike the ammonia levels once again. And no communication between municipal departments? Did the fire department not inform the city workers that dangerous fumes might be present? Did they not plan to have emergency services there during this obviously dangerous repair? I find it difficult to understand why high school football games have EMS on backup, but none was deployed to a worksite where lethal levels of ammonia were documented the day before.

While factually correct, the video is focusing on the action of disabling the ammonia alarm and not wearing PPE during the oil change. But both of those decisions were AFTER the actual mistake: attempting to restart the compressors at all when the system was suffering from 2 serious failures. Either the deadly ammonia leak or the large pressure buildup in the brine system alone is enough of a red flag to keep the system offline until a thorough investigation and repair could be made. Attempting to restart a system suffering from this kind of serious instability is highly negligent.

First mistake: Not detecting or repairing pinhole leak during the shut down period. Second mistake: After the leak occurs, and knowing there is a leak, attempting to restart anything without finding the source of the leak and repairing it. Third mistake: Valuing the cost of the ice or the event to be held on the ice over the potential injury or loss of life. I've seen this sort of progression several times over the years. Fortunately, either someone stepped in and injected reason or in the other cases, they got lucky. It is unfortunate, that the lucky cases encourage people to push the bounds of safety.

I worked in the explosives community for 30+ years. Many times I was ridiculed, cursed at, and even laughed at for following established safety protocols. Superiors would get pissed off at the overtime costs, work disruptions, and inconveniences to the community. Even those who WROTE the safety policies would get pissed off when I followed THEIR own policies. But i never wavered. Not once. And because of that, I am here and able to write this constructive critique. Safety protocols are there for a reason. Never, and I mean NEVER , ignore them or take shortcuts. Especially when those who demand you take them, will never be the ones to go downrange. Follow your protocols. Follow your training. Do the job, and DO IT RIGHT. Do that and control the risks. Do that and minimize the dangers. Do that and LIVE.

This isn’t just ammonia it’s anhydrous ammonia and it’s nasty stuff. It absorbs water with anything it touches, including all the water on your body. We had training on it at the fire department.

They should’ve had Class A HazMat gear. 300 ppm is highly likely to be lethal but when that pipe bursts i bet it got into the 10,000s. Anhydrous ammonia spreads FAST and it’s really nasty stuff. It eats away the skin and dries out the lungs almost instantly and burns them up. Nasty nasty stuff. I hope I never respond to a ammonia leak.

[@Cautionary_Tale_Harris]

This video is great for illustrating the effects of using *passive voice* in your writing in a way to obscure who acted...or who did not act. A quick example is the active voice, "We made several mistakes" vs the passive voice, "Several mistakes were made." I've noticed a few things in the narration: 1:32 "This *leak was not repaired* during the 2017 summer seasonal shutdown." Whose responsibility was it to repair the leak? 1:52 "On October 16, 2017, at approximately 6:ooam, the *chiller* for the curling rink *was started* and put back into service." Who restarted the chiller? 3:04 "*One of the city workers closed* some of the brine system and ammonia system valves; the shaking stopped." Here the wording uses active voice; probably because the city worker did something productive or effective. 3:13 "The *firefighters vented* the building." Same as before; active voice because of a productive or effective action. 3:23 "A city *worker* then *isolated* the leaking chiller and *shut the system down*." Yep, active voice. 3:34 "The firefighters *were told* they were no longer needed, and left the location between 4:3o and 5:ooam." Now with a bad decision being made, we're back to passive voice. Who told them they we no longer needed? 3:40 "At approximately that time, *it was decided* that the compressors should be restarted in an effort to save the hockey rink's ice." Bad decisions get passive voice. Who *decided*? 3:49 "However, because the compressors' oil had been contaminated with brine, the compressors could not *be restarted* until the oil had been changed." Restarting the compressors is part of the bad ideas category, so it gets passive voice. 4:02 "*An external contractor dispatched* a refrigeration mechanic to the site to change the compressor oil." Active voice, possibly to make it clear *who* sent the mechanic into danger. 4:09 "Prior to the arrival of the refrigeration mechanic, *arrangements were made* to put the ammonia alarm in silent mode for the repairs." This is a big one and probably the best example in this video of using passive voice to obscure just who the actors were. 4:35 "They were not wearing appropriate personal protective equipment and did not have personal monitors for ammonia exposure. There was no backup team, and emergency responders were not present." I included this part because, at least when I watched the video, it seemed to imply that they did not have these resources available, which may have been true. Did the city worker who initially entered the building with the firefighters borrow one of their breathing units, and when they left they took it with them? Perhaps. Of course then you have to ask why a refrigeration mechanic sent to work on a refrigeration system would not have had safety equipment on his service truck. It looks somewhat likely that the three men chose to not wear the gear because they didn't believe they needed it. What happened to these men is awful and I hope their families are doing ok.

[@SmileyxKyley]

It’s probably to avoid defamation lawsuits, and also in the case of the two city workers who perished it might not be clear which of the two was responsible for which actions.

[@straightpipediesel]

This comment is great for illustrating the effects of the grammar police commenting on something they know little about. Accident investigations, whether it be chemical safety, plane crashes, train crash, are intended to promote safety and prevent reoccurrence, and specifically not to assign blame. Further, there's two sides of every story and some unknowns, so care has to be taken to separate the established facts and things like actions that we aren't certain exactly who did what. Nobody knows who restarted the chiller because everybody who could have is now dead and there wasn't any CCTV or other conclusive evidence. Your brain is going to explode when you see some of the aircraft accident reports where sentences are required to tightly follow a formula. "It is certain that the accident was caused by a fire. It is considered highly probable that the fire was caused by gasoline in checked luggage. It is considered highly probable that the dangerous goods were not detected... It is considered probable that..... It is considered likely that...."

I am an industry insider and respect the investigators involved! How ever I have problems with blaming the service provider called to the scene getting any blame for the events that led to his death!

As soon as I heard about the pinhole leak at the beginning, I was wondering at which point in the story a weakness in the pipe system will breakdown.

[I just realized from the comments below that the relief valve WAS closed to prevent shaking of the overflow containers]. Well, that's the fatal mistake right there.

[@ateam505]

Yeah, that’s sad. Whoever closed the valves to the expansion tanks meant well, but that caused the explosion since the brine/ammonia mixture could no longer vent and pressure began building in the system. Besides that though, so many things were done wrong for this to happen.

[@OlOleander]

@@ateam505 It's kind of a perfect demonstration of the Swiss Cheese Model.

[@warrax111]

they should make the pipe leading out of the building, with weakest point installed there. So it breaks up there, outside of building. Of course, surrounded by some safe building from concrete, with alarm. But money talks. It would be safer, but more expensive to build.

[@stevep5408]

I know I'm just a stupid oul refinery Steamfitter but since when do you allow the cooling fluid to be at a higher pressure than the circulating fluid? I don't even know why alarms can be silenced. Why wasn't a high pressure alarm separate?

[@ZipperOfficial]

Also pressure relief (relief valve/ safety valve) into a reservoir should've been in located in areas prone to high pressures. Especially ones containing highly dangerous chemicals

[@jond3929]

Under normal operating conditions, the cooling fluid (ammonia) will typically be at a low pressure on the evaporator side of the refrigerator (the side where the circulating fluid passes through tubes which are cooled by the boiling ammonia). Meanwhile, the ammonia on the opposite side of the refrigerator (condenser side) will be at a high pressure. So normally the cooling fluid is at a lower pressure or similar pressure to the circulating fluid. However, when the refrigerator shuts down, there is a tendency for the pressures on the low pressure side and high pressure side to equalize (this is because the compressor has stopped and there is no longer any reason for the refrigerant on the low pressure side to stay at a low pressure). The cooling fluid pressure can then increase above the pressure of the circulating fluid. This is not unusual and the vessels must be designed to account for these high pressures as well as being fitted with pressure safety relief devices. As far as having a high pressure alarm on the brine system; It is not common practice to put a high pressure alarm on the brine side, nor is it required by law. Typically a pressure relief device will be fitted to the brine cycle to prevent high pressure in the cycle. A pressure relief device is typically fitted to the expansion tank, which was isolated in this case and so was not able to relieve the excess pressure in the system, leading to the pipe rupture.

[@mfree80286]

Water absorbs ammonia. Absorbs a great amount of it actually, and this is a simplified statement, but it wasn't so much that there was ammonia and brine separate in the saline system, it's that the brine absorbed a great deal of ammonia while operating and self-distributed, and it boiled out as the system warmed up. it's like champagne, the colder it is the less CO2 comes out of solution... but get it very hot and the bottle can burst.

Heat exchangers need to be cleaned and tested every year (sometimes less, so every 2-5 years). It depends on many things: -The products. (Ammonia might damage the heater) -The pressure and temperatures. (The high temperatures are stressing the metal, checking for small cracks (NDT) is needed!) -Additional: In same cases HTHA (High Temperatur Hydrogen Attack) is possible, in this case it´s not possible.
