At The Dive Shop Dive Club meeting we have these Scuba 101 questions...this is question #1 from the January 2006 meeting...

Hmmm, My research got me a psi that would need another choice :wacko:

oops, did i make a typo when i posted it?

Here is the answer for Jan question #1

A. 100 to 300 PSI. Do not store your tanks either empty or full. The more air in your tank, the more corrosion possible when moisture is present. There is potential hazard when a stored tank contains high-pressure air and a fire occurs. Heat may cause some tanks to explode before the valve burst disc ruptures. The optimum storage pressure is low, but not zero.

Thanks for participating
