It can be done as stated above. You can also breath directly from the tank valve without a reg.
Um, yeah...I would HIGHLY....let me say again...HIGHLY recommend that this not even be attempted unless in an ABSOLUTE LAST RESORT!
If you over extend the valve just a minute amount, (especially easy to do in a panic situation) you will go from getting a couple PSI squeezing by the valve opening to having 3,000 PSI trying to get out all at once. That would be enough to rip your mouth apart, blow out your lungs; eyes, and or sinuses....etc.
So, while it "can" be done...I would never do this unless absolutely necessary for pure survival!
(Why do I get the feeling you have been watching "Into the Blue" to much lately?)
