Hyperbaric Chamber Question.

[Jim Ernst]

A reality show Tells a story of a Female Scuba Diver doing a dive to 350ft, Something goes wrong and she has to bolt for the surface.

She makes it, But of course has to take a chamber ride, during the time she is in the Chamber, somehow someone Opens the chamber door and it instantly Kills her and sends Blood flying......

I hate to sound Stupid, But could there be any truth to that???????????


Thanks in advance!!

Wow, No one Knows......?? Anyone???

I assume you're asking about: "1000 Ways to Die - Tanked Girl #710."

We've done this one before, there's a whole thread on it. My opinion is that, from what I know about chamber design, it is not possible ... the doors of treatment chambers are sealed by the pressure and can not be opened unless the chamber is surfaced first. It's a fraud.

Well it would make sense that it could kill her almost instantly since it would be like literally rocketing to the surface from whatever depth was being simulated at the time. That would be some serious DCS. As far as the ability to open the door while the chamber is pressurized, not sure about that. Anyone?

I used to be a chamber operator for a multi-lock chamber.

The doors had no locks or latches of any kind. The door was hinged to the inside, so interior pressure held the door closed.

We once tried pulling the door open from the inside. With two of us pulling we couldn't do it when the chamber was at 30 fsw, so we kept getting shallower and trying. We were able to force the door open at about 1 or 2 fsw.

So the first big hole in the story is opening the door.....let alone the slasher film blood splatter....


All the best, James

I thank all of you, I didn't know this had been discussed Before, But I do Appreciate all of you answering me, I thought that story was BS, But it was on some live or die TV Show that my son was watching tonight!!


Thanks Again Guys!!!!

Multiply the area of the door by the pressure in the chamber, its not opening ... no way!

I pretty much thought so...

But , I had to ask, thanks again Thalassamania!!

Lets see, we'll make an assumption of a normal treatment depth of 60 fsw. Thats almost 66 feet or 3 atmospheres absolute. (Note- if anyone feels like running the real numbers knock yourself out- this is just a rough approximation ) Thats a bit less than 30 PSI more on the inside of the door than on the outside.

I'll use Catalina as an example since I work there- the door is held shut by the interior pressure when the chamber is at depth. (Chamber doors open inward) Door is (very) roughly 5' x 3', or 15 square feet. That works out to 2,160 square inches. If we multiply by the 30 PSI that would get us 64,800 pounds of pressure holding that door shut. (It's a steel door and probably a couple of inches thick)

Offhand I'd say we can call BS on that one.

Booo, I was coming here specifically to do that math, then make a hysterical joke about me being able to do it after growing up drinking my milk...

Alas, you have deprived ScubaBoard of my genius comedic stylings.
