No matter what they say now, There is no way Ill go into those so called safety cell rooms in those death trap Tunnels. Id get out and walk towards an exit, yes I might die from smoke, but id rather that, then going into those no exit rooms.
Tunnels are sectional structures so I don’t understand why there isn’t a capability to close off a section or multiple sections to prevent air going in also rigged with fire systems like powder or foam. Entering a tunnel to fight a fire seems unrealistic in most cases so there needs to be a way to use the design of a tunnel to our advantage to reduce risk.
Being cooked alive is a horrifying way to go but I can think of worse. I believe the saying is the only thing that scares people worse than burning to death is being eaten alive.
@@_Meng_Lan are those safety survival cells not supplied with fresh air from another source? To me that would seem like a necessity for a 'survival' room.
RUclips isn’t a fan of people using the footage for some reason, I’ve seen a lot of people have to censor it to avoid age restrictions and/or demonetisation
This documentary is very interesting. But, from wich year is it? I see the construction of a skyscraper in Moscow, that is due to be completed in 2010!!! Uh....Sorry?! It's 2024 now! So this is very old! Or am i missing something?
Again, they forget to mention and explain why the third building , (building 7,,)went down on 9/11. It wasn't "hit" by any plane, so no jet fuel to melt the beams- ?. Duh,,, gee, I don't know!? How did that happen?? 🥴
sorry to disappoint you. The reason is that the damage to the foundation of both towers and the underlying structures did destabilize the foundation of WT 7 as well. There's been a Subway running underneath. All these factors were enough to cause the internal structure of the building to disintegrate over the next hours. It's that simple. But of course, if the tinfoil hat is too tight.......
@@theanteaterparadox344 uh huh. yep. That mustve been where the plane parts went from Shankville and the pentagon. And any videos of a plane hitting the pentagon. ohh! Wait! Breaking news coming in from my tinfoil hat_........Ray Epps cleared, Media and Biden fake laptop prove russians and Trump responsible for all. 87000 irs agents confirm.
why most tunnels are not fitted with exhaust 2 meters incline tube ducts at every 500 meters for every 2Km lenghts or every 250 meters for more than 2Km strectch run of every tunnels regardless of its locations or depth undersea or below mountain
Yes margarine is flammable. Margarine is basically vegetable oil solidified through a process called hydrogenation. It is not very volatile at room temperature so it is not easy to ignite it, but if you heat it it melts to liquid and will start to vaporize. It can then be ignited and once you get it burning it contains a great deal of chemical energy so creates a large amount of heat. Think of a wax candle... At room temperature it is solid but you can start it burning by melting a tiny amount of the wax in the wick with a match.
@@Rondon68 There is no need for ad hominem attacks. Tyani asked a fair question and I expect a lot of people would not think of margarine as being flammable. It certainly was not considered a dangerous cargo by the people running the tunnel! They have learned better now... By the way, I hate to be a grammar Nazi, but your 6 word comment "@Tyani-s, your not very bright are gou?" has 3 errors in it. First, the word you are looking for is "You're", not "your". Since it is at the beginning of a sentence it needs to be capitalized and you need to use the word that is a contraction of "You are" not the word indicating possession. Also the word "you" is spelled with a "y" and not a "g". I am sorry to give you this bad news, but perhaps a little more thinking and some proofreading would help you become a better RUclips commenter.
So, the old safety rooms couldn't cope with a fire of 1.200 degrees raging for 56 hrs. So they build new safetyrooms able to cope with 1.000 degrees for 4 hrs. Sounds like a comedian made the changes.
The only smart thing they added were actual escape tunnels that are accessed through the safety rooms and lead to the outside. Why they thought a bunker with no exits was a good idea for the first one they made, is a bit beyond me. I guess that the saying of “every safety regulation is written in blood” can be applied for this tunnel
EV vehicles are the biggest threat to tunnels and bridges imaginable

Extremely informative. Live long and prosper.🖖

Try finding the distribution of steel down any skyscraper.
Don’t know if I’d call a tunnel a miracle of modern engineering considering the oldest tunnel excavated is from the eighth century.
bet it didn''t have electric lights or fans though

You seem fun
We're talking proper tunnels here mate

They died lack of oxygen first probably

why did you blur out the 911 footage? i think everybody has seen the videos so why censor it?

am sure the Dubai tower had a massive fire
Super old videos on the skyscrapers

Think hard. It's not that difficult. Think thermite....
Yep. Plus for 3 months before that, the "Acme" Elevator Co. Was doing "major upgrades"" to the elevator systems. That would be access-
capitalists gonna capitalize on free money. every time. especially when they have enough money to influence governments

Documentary’s like this provide great knowledge to Archtect’s, designers and engineers in this field 🤞
The lesson from 9/11 is don't do controlled demolitions while people are still inside the buildings.

What would you suggest to bridge the difference?
