not always possible and not necceserily safer they will still have fires and crashes

@@jimmyormerod4075 generally safer in that in the event of a fire, there is usually an escape route (the other tunnel).

You prolly dont give a damn but does someone know of a method to get back into an instagram account?? I somehow forgot my login password. I love any tricks you can offer me

@Derek Enzo instablaster ;)

@Dalton Adriel i really appreciate your reply. I got to the site through google and im trying it out now. Looks like it's gonna take a while so I will get back to you later with my results.

@Dalton Adriel it did the trick and I actually got access to my account again. Im so happy:D Thanks so much you really help me out :D

@Derek Enzo happy to help =)

EPA junk in a nut shell.

To be honest I wonder why this hasn't happened in America? I've never heard of trucks just spontaneously catching fire like this.

I pictured a kangaroo in a tunnel. Speaking of vehicle tunnels, do you guys have them? And if so, are road trains allowed to transverse them?

Right? Does it just cost too much for a multi billion dollar project to add some sprinklers?

@@will16320 Even large Sprinklers wont be effective enough at putting out these huge hot fires like the examples in the video, you would need insane amounts of water. Also water on certain chemicals or hazardous goods that may be getting transported can make the fire worse or even cause large explosions. Its definitely been thought of before, and unfortunately its not practical

@@j3sspyle Hi Jess, sprinklers would hopefully prevent a fire from reaching a 1000C temp to begin by dampening / suppressing the early stages of the fire and completely smothering it before it can become something more serious, such as a fuel tank ignition. Whilst the sprinklers at your home use water, Modern commercial sprinklers do not use water, they use foam which is effectively the same as ABC powder and can be safely used on any fire type. Check out videos of it in petrol stations and aircraft hangers, highly effective against fuel fires. There may be other practical considerations but water availability / effectiveness of sprinklers are not issues

In Australia I believe our tunnels do have this

That is fine for a short tunnel, but I was 6.5km in, smack in the middle of the 13km tunnel and there is no way I'd have been able to run that distance in the heat that was building up, so would probably have got in one of the shelters, where I'd have perished like those who did so on the French side of the fire as the heat passed the failsafe temperature of the shelter. I was better off waiting for the fire crews and tunnel direction vehicles to pick us up and get us out of there. Also those who tried running out on the French side who weren't already near the entrance were all overcome by the toxic smoke, so collapsed and died before they'd gone more than a hundred metres or so. They didn't realise there was a fire until they saw the smoke approaching fast towards them, once the lights failed the ones further back never even saw the smoke in the first place, so died in their cars.

the tunnel is used with roads to connect inter Switzerland and Italy.

@ronald nolan Its a 100km drive to the Italian border from the south portal and I couldn't find anything backing your statement.

The Tutorialist no it doesen t, the tunnel starts in the Italian part of Switzerland, and end in the German part of Switzerland.

BrauseKL I think they mean the Italian part of Switzerland.

ronald nolan the tunnel doesen t go to Italy, it ends in the Italian part of Italy.

Probably funnelled off to less populated areas then runs through scrubbers, just like you get on factory exhausts.

Licensed background music and royalty free music that are used in documentaries are never on Shazam. Nor available to buy on Spotify etc. But in the case of the introduction, the music might have been composed for this series specifically

Extracting the oxygen is not that easy and if it was possible it would have led to the death of everyone in the tunnel, including me and the ten other survivors on the Italian side of the fire who couldn't turn our trucks around in the narrow tunnel to drive out. I certainly couldn't have run the 6.5km to the exit before becoming overcome by either the intense heat or toxic smoke as it spread throughout the tunnel once the fans failed.

Yes, it's really obvious, but it's still much better than the dubbing over most documentaries do.

That is swiss german, specifically a dialect which is spoken where the tunnel is, in the canton of Bern. there are many dialects in Switzerland, in every region they differ between one another.

I believe this video is wrong, I watched a documentary years ago about it, and it says that the controller actually tried to suffocate the fire, by extracting the air, this in some respect helped, however also sucked the air in the tunnel out, meaning that people running to safety suffocated (assuming they didn’t die from smoke inhalation first), and that those trying to turn their cars around and escape in their vehicles couldn’t, because their engines cut out and wouldn’t start as there was no air, it was being sucked out by the ventilation fans, and any remaining air was being rapidly consumed by the fire.

@the fiesta guy, he didn't extract the air, that is impossible because the tunnel is open at both ends, so extracting it at one end would just pull fresh air in at the other, he tried to blow the smoke out of the tunnel so people wouldn't suffocate, but the smoke was already too thick and any oxygen not already consumed by the flames was pushed to the top of the tunnel by the heavier dense smoke beneath. Even if he hadn't switched the fans to maximum (until the wiring burnt out), those on the French side would still have perished as the lower air pressure on the French side of Mt. Blank was dragging the smoke through that way anyway (which was the normal way the tunnel was ventilated, but usually around 330 days each year it is lower on the Italian side, 30 days on the French side and around 5 days per year it is equal and the fans need to be on full blast or the tunnel closed). It is only the fact it was one of the 30 days of flow towards France and the fans blowing in that direction too, that meant myself and 10 other truckers survived.

It's the carbon-monoxide in vehicle exhausts that's the killer, as it replaces oxygen in the blood-stream!

The Tutorialist how many times do I have to say it?

Firstly he was Belgian and secondly he was 6.5km into a 13km tunnel, there was no way Gilbert could drive it another 6.5km once the cab started burning. There's a huge difference between a hundred metres and 6,500 metres pal..!!

P.S. if he'd tried, then he'd have passed my truck 100 metres further on and I'd have died of smoke inhalation too, along with another nine truckers behind me and all the ones behind Gilbert would still have died anyway, so by stopping where he did, he saved eleven of us, not to mention the car drivers on the Italian side who managed to turn their cars around when nothing was coming in the opposite direction.

Fair enough.

On May 13, 1949, a bad collision occurred by two trucks, carrying hazardous materials, in the Holland Tunnel's eastbound tube. A major fire ensued. A ceiling section was destroyed, It took both the New Jersey and NYC fire departments to extinguish this huge blaze.

Automatic water sprinkler systems will fail to function in a long, artificially ventilated tunnels as the hot air will be blown by them big turbines causing it hard to detect where the actual fire located. Basically, it will be overwhelmed by the tunnel's airflow, so it's not as effective as it should be. Sprinklers may be used in naturally ventilated and or short tunnels.

A detection system should be in place. What the @#& is wrong with engineers.

Fire sprinkler isn't always the solution for fires. As a Hazardous material hauler myself, I carry elements that would explode if contact with water was made. Having a semi trailer that caught fire under one of the sprinkler suppression would be far more catastrophic then one would think. If my truck catches fire I have to call the dispatch to not send water trucks for the main fire but foam trucks to spray.

Probably because these tunnels go up and down, pooring it full with water would simply flood flood them.

Baron von Limbourgh the tunnel don’t go up and down, they start at a low point and go up to the end or to a middle point and go down again, this is maid so that the rain water that goes trough the rock can flow down.( maybe they also have channels for water)

Probably because the faults leading to that disaster were related to the train and had nothing to do with the tunnel. I don't know if the tunnel itself was ever criticized.

Even something like a jersey barrier would help somewhat. Maybe they don't want to do that as it would block emergency vehicles being able to drive down the middle? The reason highways are so much safer than surface roads is due to the separation of opposing traffic flows.

Musk: hold my glorified sewage pipe deathtrap

*What a retarded comment u loser*

Apparently there was some evidence given by witnesses driving in the opposite direction, that the fire started in the engine's air-filter intake (possibly by a lit cigarette-butt)!

ive heard it all now thats not physiccly possible mate the tnnel is way higher then the lorrys and the lorry wouldent be scraping against it for miles would it now it would have been a mechanical fault like most car fires

Absolute rubbish, all normal trucks in Europe run at a maximum height of 4 metres because of bridge heights on the motorway system across Europe, but the alpine tunnels are higher than that to accommodate 'convoi exceptional' vehicles that can't normally use the twisty alpine passes over the top. The main suspects for ignition were a fractured fuel line leaking diesel onto insulating material around the exhaust, the aforementioned careless cigarette but, or an overheated brake disc that had been binding. Even Gilbert Degrave, the driver couldn't say which when we spoke in the hotel whilst waiting to see if we could drive our trucks out once the fire was out (obviously Gilbert couldn't do that anyway, but as it turned out 3 days later, neither could the other 10 of us).

Which, in many cases can make the problem much, much worse. Apparently you've never heard of Class 4.3 Flammable Solids (aka Dangerous When Wet) materials that are often transported on...wait for it...trucks!

The goal is to prevent fire and not only give protection after its stated

they cant work fucking miricles haha thats the best humens can do right now what do you expect

The original fire shelters could only withstand temperatures up to 800°C for 6 hrs maximum, but with no escape tunnel that made them a death trap oven in this case. The new shelters can withstand 1,000°C for 4 hrs, giving those inside enough time to be safe waiting if it's a smaller fire that can be extinguished reasonably quickly, or if it develops into a more serious fire, they can exit safely via the new escape tunnel doorway in each shelter to a central air fed access tunnel beneath the roadway level. That is what makes it safer.

Morse Code Reviews modern cars catch fire more than old ones used to.

You know, there are some people in the German part of Switzerland and also some Germans, to be honest, a lot of them, and some of them drive like there are no laws, I can say this because I’m from the Italian part of Switzerland and my mother is German.(I know how people drive in these places)

@@user-ky6vw5up9m You've forgotten about the 1990's

car and truck fires happen al the time you just arent going to hear about it unless its major its usually just and inconveinace and cost to the driver but if its in a tunnel its dangerouse when you have millions drive throughe a tunnel a year your gonna get hundreds of fires its part of having a car or truck theres risk of fire learn how the engine works and youll realize why its so common

actually the winecoff was fire proof its steel structure held up and didnt collapse as it was suppsed to

We're now trained to carry on driving, only stop if you absolutely cannot drive any further at all. We're also instructed to not stop near a bridge, homes, or drainage if possible.

That would be too smart

What a brilliant idea. You must be a genius!

...also this is where autonomous vehicles could really have a great impact. Imagine if the whole line of cars could just reverse back out of the tunnel perfectly in sync!

The people inside would have suffocated

@@sad1234ee Great point, and a good example they have fire rescue specialists tackling fire tunnels and not someone like me 😁 I'd suffocate everyone trying to get out!

@@DamianDeEu electric vehicles would be the only thing that could save people here, lack of oxygen conked out peoples car engines before they could escape
