Hell, even a pure vacuum is survivable.
I always thought films that show someone surviving a vacuum were utter BS, but then researched it a bit and found it is quite possible to survive.

A bloke at work once took a deep breath of helium and then ran off while holding that lung of helium to show his friends what a funny voice he had.

He got about 20 meters and dropped like a stone. He came round again as soon as his brainstem overroad his moronic frontal lobes.

As Polwart says, he was a moron before the incident.

Why do you think you don't stick your head in nitrogen purged vessels and use a gas monitor instead?
Ahh now! If we're comparing grabbing a lung full from a tube (as originally mooted) to entering a Confined Space, that's a different kettle of Haddock. Confined Spaces,,,, welcome to my world!!

Not entirely, with nitrogen been heavier than air they is the potenial for the deck to fill with nitrogen, if the user was to inhale a lung full and "faint" as suggested they would fall into the boat where nitrogen could have already collected, then die.... whats the difference between popping your head into a vessel and getting a lung full and getting a lung full from a tube?

But if enough nitrogen had leaked out of the tubes to fill up the deck space, the tubes would be flat, allowing all that heavier than air N2 to run out onto the floor/sea. This would create a partial vacuum on the deck which would then fill up with luverrly O2 rich air.
Your move (probably to the bilges)
