[PSUBS-MAILIST] submarine escape procedures

[hank pronk via Personal_Submersibles]

Cliff,
Thanks', I spoke with a diver friend about bailing out at 400 feet.   He said it is very doable, but suggested taking a couple of breaths of another type of gas, I think it may have been helium.

Here is the escape trunk placard from the USS Albacore, the one on my boat (USS Torsk) was much the same. Note the bottom times on the bottom.

I have a Steinke hood in protocol but not sure I would use it.  Had a long discussion with doctors and tech divers.  As Phil notes ,  issue is onset of nitrogen narcosis rather than bends given the short time exposed to pressure.  Would be an uncontrolled ascent.
