Doomsday Bunker question ?

    So I've been watching the Doomsday Prepper series and have question regarding the various underground bunkers.

    Where is their air intake, I'm thinking there must be a pipe that leads up to the surface but if so what is to stop someone sealing it up or using it to smoke them out ?

    From what I understand people can hide them in bushes and/or other structures. Beyond that some may have recycled air systems which are much safer.

    I've seen some pretty elaborate systems where intakes and exhausts were redundant and disguised well, but these were large, long-term construction projects, were extremely complex, and the people had ample financial resources at their disposal. But as always, any static position is susceptible to siege by a determined group. Just as important, in knowing this, were the redundant means of emergency egress that were disguised just as well.

    I too wondered what would happen if someone just blocked it. Eventually, the people inside would have to come out!

    I seen one that had his generater stolen and wondered why they wouldnt just build a small run underground for it.

    IMHO, underground bunkers/shelters should be considered very temporary, at best. Yes, given an unlimited budget, they can be made pretty well. But as stated, you gotta be able to breathe. If air can go in, so can other things, like gasoline. Even if there is a diverter for just such a situation, the fumes will permeate & spread. Even if the fumes were not ignited, you would smell them & WANT to get out, because you know your done & if they were ignited, BOOM is the last thing you would hear. The end result would not be pretty if the people were determined to get you out at all costs. The only way to have one that is indeed at a "secret undisclosed location" is to transport it from the maker yourself, at night, with it covered up & have the equipment to dig the hole & set it in yourself & not tell the maker where you live, pay cash & hope no one in your family accidentally lets it slip.

    Nat Geo would be better serve the public by having a show that shows how to build a low cost storm shelter & ways to build houses stronger & safer to begin with.

    It was underground & bolted to a concrete pad. They dug it up & unbolted it & stole it. That was supposedly "at an undisclosed secret location" too. My money says it was one of the workers or their friends or they were just scoped out & followed during transport of the shelter.

    I was thinking the same thing when I watched it ! I think if you bury yourself underground & it's a real End of the World type of thing then it would just be a matter of time before you were found ! Especially if there is some type of generator of fan running all the time out in the middle of nowhere !

    I don't see any waterproofing or corrosion protective coating on the outside. Inside I see regular cabinets and plastics.

    In that type of confined space every material would need to be carefully considered.

    Anyone here with submarine experience?

    Some of them are all plastic to begin with (converted water/gas tanks), but the custom Steel ones are indeed sealed both inside & out with waterproofing materials.

    Some people might consider this meaningless but the off gasing of those materials can kill you.

    They learned this the hard way in submarines. Something as seamingly insignificant as vinyl binder covers has caused serious illness in young strong 18 year old men. Imagine the poisonous off gasing of all the other materials combined in that tiny space, your kids breathing that air would do well.

    I can see using such a shelter for a very short period of time to ride out a hurrican or tornado but not longer than a day and a night.
