@@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

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.

In respect of the fire in the Mont Blanc tunnel I would not have associated margarine with such a devastating and intense fire 🔥, whilst I appreciate it is a type of fat and as such will act as a fuel for fire I would never have guessed it could be so damaging. Surly in the event of fire you would always want to extract the oxygen and smoke from a tunnel fire, not draw fresh oxygen in to support combustion, perhaps I am looking at it to logically and simply but surly denying fire any one of the 3 elements needed for combustion should be a simple matter.

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.

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.

@johnwhitby5482

Жыл бұрын

@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.

silly why add a flammable surface to a concrete tunnel. All you need is a rough surface for traction.

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.

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).

My instant thought is why are there not 2 tunnels for the road with two lanes and emergency lane each with stops every km?. Why have traffic going both ways in a single damn tunnel one lane. Worse design ever and cheap for a country like Switzerland.

@JaidenJimenez86

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.

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.
