Tragic? Yes. Accident? NO! "...he had left a fork-shaped bracket on the cable car’s emergency brake to disable it because it kept locking on..." Likely, the emergency brakes were dragging and the wire rope was periodically overloaded.
Either the blood spilled before they were written, or the blood spilled by them. Don't blindly trust the standards, they're not always written to protect you.
In the army we had a rule about proper positioning around APC's when they're being prepped for repairs or finished up. One of those includes "not shoving your hand into a turret mount while the electrical system is connected no matter what" We even got the recording of the screams of horror and pain of the person who didn't follow that rule. Also had a coroner report for the guy that pulled open a drop-down back door of an APC. It mostly read "shattered piece of XYZ" or "Shredded piece of (presumes) XYZ". That gets people to really respect the rules.
@@ScarletFlames1 Had a tanker buddy once tell me about a rule they have about keeping all extremities away from the breach when its loaded, apparently one guy thought his phone was more important then that rule. He had been recording with his phone and had dropped it after he had just loaded a round and bent down to grab it without thinking then WAM. The pictures look like somebody took a 2000lbs bat to the dudes head or what was left of it anyway. Rules are definitely written in blood
"THERE ARE NO ACCIDENTS!" These were the first words the instructor said when I took the OSHA safety class in college. The instructor introduced her self, reached behind the desk, pulled out a huge, thick book and slammed it down on the table and said "there are thousands of safety rules written in this book. The one thing they have in common is they are all written in blood." Hundreds of pages (probably over a thousand). Then she asked someone to call out a page number and she read the safety rule. This went on for 15-20 minutes. Her next comment was "The majority of these accidents were due to lack of common sense". Her final comment that began the discussion was there are no accidents... every accident is preventable". We then picked apart 25 or so accidents that each of us had seen or been involved in. This happened...why? Because of this...why? Because this... why? She took every single example and reverse engineered it to its beginning and where it started and how it could have been prevented. Lazy maintenance workers cut corners, lack of common sense, goofing around, lack of observation, complacency, poor housekeeping, improper use of tools or equipment... the list goes on. In the following weeks we studied so many scenarios... every single one could have been prevented or by using proper safety equipment and PPE the outcome would have been different and someone would not have been injured or lost their lives.
I had an ole' timer once tell me "Even if someone has been doing something for 30 years doesn't mean they have been doing it right!" I still apply it to my job.. and it still holds true
This reminded me of something said of a so called expert. "There's a big difference between twenty years experience and one year of experience twenty years ago".
That is the fault in his "never seen that happen before" argument, then he needs someone to fall to their deaths at least once to learn that it CAN happen. Idiotic logic. People have imagination and foresight for a reason.
I've left several jobs because of the phrase "we've always done it this way." Just not worth arguing with that mindset especially when safety is involved.
@@SocietyIsDoomed I would have thought the outer wires would be the first to go since they'd be under the most compression/tension when they change direction.

The elevators in my office get annual inspections. I can’t believe there are not bus loads of inspectors for every conceivable form of transport in a EU country. It boggles the mind this could go unnoticed for so long.
2014..... Wow. So did inspectors never try and test the emergency brakes at least once during all those years? It's safe to conclude that the inspectors either. * Did not do their job properly... Or * Knew the brakes were disabled and failed to report it.
"WORST-CASE SCENARIOS ARE ALWAYS CONSIDERED UNLIKELY" If you’re an analyst/mechanic/manager responsible for warning or risk management, remember that when you paint the most dangerous scenarios as worst-case, you make it easier for the decision-maker to dismiss them. Use language like "most-consequential" and not "worst-case."
It’s sad to think of all the men whose blood and sweat went into building that thing which included (among thousands of design elements) designing, building and installing a brake feature that was, decades later, disabled for negligent reasons. Hard work disgraced. Pride lost for foolish reasons.
It didn't happen just recently that the brakes have been disabled. Part of my family have worked for different companies (to make sure the owners of the cable cars are sticking to proper safety procedures etc.) in the Alpes and they can vouch that that has been common practise since (at least) the 1970s. In the capitalist system it just isn't profitable enough to keep the brakes on at all times. Why? Because whenever the wind is too strong or something else happens, that is out of a human's control like the weather, the (very sensible) brakes already intervene and it angers the greedy owners. Caring about humans isn't profitable, but using humans as cannonfodder sure is.
@@andrevdm6406 i agree to an extent, but this was not the doing of a youngster. Quite the contrary. So perhaps your perspective is worth reconsidering. Or just chalk it up to an ‘exception’ and continue living in the ignorance of generalizations.
@DavidSharp also expecting its the responsibility of the guy at the bottom of the pyramid to quit as the solution is no solution at all. Right or not people will chose to feed their family over yours when push comes to shove. The incentives need to involve the higher ups. It is their responsibility to verify the working conditions are such that safety can be maintained as much as it is the workers to follow the safety guidelines. The liabilty needs to go further up the chain than it currently does in practice.
In Italy the CEO or founder of the company is ultimately responsible for safety He can delegate the execution, but not the responsibility The other people involved should only get the equivalent of aiding and abetting
I have stopped two "orders" that way! They do that so they look good that production started again, but when things go sideways you are left holding the bag!
As someone who just got hired by a facility with significant amounts of deferred maintenance: nothing is more permanent than a quick fix to get back in production.
A friend of mine was the safety inspector at a theme park years ago, he shut down a coaster because it was unsafe. The park fired and replaced him and a week later the coaster went off the rails. Profit > Safety
I worked as a ride operator for a summer, and thankfully they took safety really seriously. Every day before opening an engineer would inspect each ride. Then the manager would inspect every ride in their section. Then the ride operator(s) would perform a third inspection. Shout out to Oaks Park outside of Portland OR.
Italy has a ton of government. How corrupt it is might be a different story. I completely agree with Ave. This management and if their government gives final oversight then they're management.
Disabling the breaks seems to be at the level of criminal negligence, like drinking and driving, and those responsible should be tried for manslaughter.
exactly! just like in plane crashes when airlines are caught cutting corners and it leads to a fatal accident they get charged for it same should be happening with the maintenance crew or at the verry least the company running the cable cars
This whole situation with the brakes sounds like when someone replaces a fuse with a bigger fuse, then finally wraps the fuse in foil, because the circuit keeps popping fuses. The brakes dragging was a symptom of a maintenance problem, not the source and cause of the problem.
@@imgoodaswell9558 Haven't you? People also tie up the emergency levers that requires constant pulling to not stop the action on lawnmovers, chainsaws and logs splitters all the time.
A friend of mine had a new car under warranty and the turn signals blew the fuse. Garage looked at several times and shrugged. We wrapped the fuse in tin foil and burnt out the entire wire harness....then they fixed it.
@@Narcan885 I had an old Sabre lawn tractor that I put a big wire tie around the seat sensor. There was no way to get on and off it other than shut it off. That doesn't work with a leaf vac with the garbage can you have to empty every row. The battery died before I got very far. The newer X500 I have now lets you engage the parking brake and hop on and off (the brake also turns off the blades). So sometimes the safety is so badly designed it's useless. Not the case with the cable car, but poorly designed safeties are more likely to be disabled than well designed.
I LOVE these talks on safety or standards. They give me ammo to bring into contract talks regarding maintenance scheduling. As well as justification for making management follow through on time sensitive work orders & requisitions.
@@rogerborg I can't wrap my head around this "too big to fail" approach to the corporate world You're looking through the same lense as described in the video- the comodifying and dehumanizing of the individual You may never again work in system that pays out six figures, but as an able bodied human being there is always a path to proactive behavior. You find people to work with/for who have the same outlook when it comes to doing the right thing
This "accident" has had a strong impact on all of us here in Italy. Heartbreak: yes. Surprise: no. And that's very sad in itself. We've had countless "accidents" on infrastructure over the years. This one, as well as the bridge collapse in Genoa, just to name another. All of these events have the same underlying cause: WILLFUL lack of proper maintenance. They knew the strands in the Genoa bridge were corroded, they knew the brakes were faulty on this aerial tramway, they knew the track was faulty when a train derailed a couple years back. Like AvE would say, IT NEVER ENDS. I am disgusted.

This is such an important video. Every engineering school, or mechanical trade school should have to watch this before starting in the field. Good stuff
@@MattBrownbill there's a reason there are so few. Unfortunately, covering up mistakes and liability tends to hinder these. You never see entries like 'found safety cable just had one thread left, suggest check more often.'. That's why we tend to have to write it in blood. The other thing is, things get found on inspections and I think most of the time people don't realise the significance - IF a series of events had lined up. For example, a paperclip falling into a keyboard in a subway control office could set of a chain of events leading to a dozen deaths.
@@MichaelOfRohan Agreed. (Assuming you're not being sarcastic) Isn't it sad that when somebody speaks properly, we notice it and feel the need to bring it up?
Damn. That was some truly horrific negligence. I can't even begin to imagine the stark terror those poor passengers must have felt for the few seconds it was going downhill. Heads should roll for that dereliction of maintenance. They're called emergency brakes for a reason - purposely _locking them out_ for other than a brief test is unforgivable.
Invent something foolproof and the world invents a better fool. Could have put every stop gap and interlock in place and someone will have been told to bypass it.

As an aircraft mechanic, this makes my stomach turn. When you have a job that involves repairing vehicles that transport multiple souls, there should never be a shortcut to get work done.
When I was a young guy in the service, working as a mechanic, I recall hearing a Captain give a safety briefing prior to a lot of equipment being moved into a new hangar. He said simply that "There's nothing in this entire building worth a human finger". That stuck with me, and has allowed me to enjoy a lucrative career working with construction equipment, primarily on aerial work platforms. Just keeping what he said in mind became the very strong work ethic that I've developed, something I've had to defend when confronted about repair costs, and I've even gone so far as to my refuse to perform sub-standard work on a variety of aerials and earthmoving equipment. And I sleep well at night because of it.

@@AlessioSangalli This would fall under lock-out-tag-out, and the disabling of said brakes should also result in the machine being mechanically unusable until the brakes are re-engaged.

Probably very poor troubleshooting abilities. the hydro e-brake applies when there is a drop in pressure. the brake was dragging, indicating a possible valving or other pressure related issue with the hydro pack. too little pressure, the brake partially applies and drags the cable. or, another type of mechanical problem caused the dragging. has to be fixed properly in every case, no exceptions.
i work on manlifts for a living, there is one overwhelming rule, never disable safety equipment. ive had alot of customers ask me to bypass a limit switch, or let them know how to bypass one. once they ask that i leave my lockout on the machine and let my boss know, take pictures and leave. had people ask me to just pencil whip an aerial inspection also, thats not going to happen. people forget how dangerous these machines can be, you can get lucky 100 times and nothing happens but that one time something does can take a life.
The local large reputable elevator company came to service the elevator in my building. They took one look, disabled it, and said it would need extensive repairs and/or replacement.

Everyone running the system with red maintenance safety lockouts in place is complicit. If they don't know that is inappropriate then there is another training failure. The trusting public doesn't know what the red bits indicate.
Negligence is when someone fails to do something they should. These people knowingly did something they knew they should not. It's not negligence, it's far worse than that.
This was no accident (a series of random, unforeseeable events leading to an outcome). It is a mishap, which is a chain of events that occurs leading to an undesirable outcome. Mishaps can always be prevented. The first mistake here is that the bean counters run the show with the mentality that we run it until it absolutely needs fixed {it breaks}. The second is that the technician believed it inconceivable that the cable could break, which makes this tech lazy and inept. The rest of the events in this mishap are plainly obvious. I have seen the corporate profit mentality in action and it is very literally 'if it ain't broke, don't fix it'. Then you have the operators that are the first ones to notice a problem and keep running until it breaks. Rather than dealing with a small problem now, they wait until it's a big problem and production stops and complain the whole time their machine is down. Like they say - if it jams, force it; if it breaks, it needed fixed anyway. This mentality at all levels is becoming commonplace. It's all a safety first until it interferes with profit.

In italy the infrastructure is basically a giant minefield. Imagine: you are transporting a 35t cargo on a bridge that has a 40t safety limit. The bridge collapses. The company that transports it is at fault, even if it's is rated for 40t. To carry parts needed to build a chemical plant, every road on the truck's path needs to be analyzed by the company itself, even if the cargo is nowhere near the stated bridge limit.
So given the cost of doing that any Companies moving heavy loads are effectively rolling the dice. It must be a huge disincentive for companies looking to invest.
As a young aurcraft mechanic the guy training me used to say , every time he filled out the paperwork and signed the forms, do you know what i just signed?

NASA did a presentation called "Normalization of Deviance." It's applicable to situations like this brake override. Definitely worth a watch. Edit: A former NASA Astronaut
Nasa is one to talk about Normalization of Deviance. Between their history of failed launches, deaths on the gantry (Apollo 1), and lost orbiter (Challenger 73 seconds after launch, Columbia breakup upon reentry), they have lots of material.
I am impressed by the amount of knowledge you have on all the things mechanical and electronic. It's a shame they didn't do the maintenance properly...
In my experience as an engineer this kind of stuff happens when management starts putting unreasonable schedule/cost pressure on people. You ultimately see a shift from prove to me this is safe, to prove to me it's unsafe. Deviance becomes normalized and then eventually someone dies. It's sad and disappointing because there are standards and they exist for a reason. As someone who serves on ASME BPV committees I can say it is basically always the case that it's due to death (in the case of the BPV go check the Grover Shoe Factory out). You would think after the Bhopals and Challengers the world the lesson would stick, but it never lasts all that long unfortunately.

I have seen this out in the field: "Get our system back up and running!!" "Okay, okay, uh... let me just, uh...." The line manager does not care about whether the system is safe. He wants it running. And that's all.
I appreciate your commentary on this one. This affirms my default position when deciding weather to down a piece of equipment over bypassing a safety. I work on industrial emergency power generation. I always take the "what if " position . Sometimes the customer wants me to leave the unit in service because the particular " what if " event is a 1 and million. Your outlook on this shows that shit does happen and when it does , people die. I always document along with taking time stamped pictures of the method used to lock out the equipment . I have brought units offline before only to find out they have been placed back in service after I left the property.
Sadly, I think every safety rule book out there was written in blood. Someone out there had to get hurt(or killed) before they knew that a rule was needed for that.
You are NOT wrong. I worked (43 years) for a huge Oilfield service company in the Wireline division. The way you describe the construction of, and failure modes for wire rope is exactly correct. We have a facility dedicated to pull testing wireline cables and testing splicing techniques. I witnessed several tests where the wireline broke. It is scary as hell. Keep up the excellent analyses.
