Handling and storing compressed gas are inherent parts of virtually all diving activities, whether conducted with scuba or surface supplied diving equipment. It is imperative that divers be familiar with the safety aspects of handling compressed gas. Diver's compressed gas shall be stored in military standard (MIL-STD) or DOT approved cylinders or ASME flasks applicable to the type and pressure levels of the compressed gas being stored.
Compressed gas shall be transported in cylinders meeting Department of Transportation (DOT) regulations applicable to the compressed gas being handled. DOT approved cylinders bear a serial number, DOT inspection stamp, a pressure rating, the date of last hydrostatic test, are equipped with applicable cylinder valve, and are appropriately color coded.
