The Guide applies to all Stanford University facilities, including leased properties. It covers all unfired pressure vessels (i.e., storage tanks; compressed gas cylinders) that have been designed to operate at pressures above 15 psig., including the storage and use of compressed gas cylinders and cryogenic fluids.

Note that there are numerous regulations governing the proper use of compressed gas cylinders; use is not addressed by the Guide, as it is a work practices issue, rather than design feature.
