Interim Air Purity Guidelines for Dry Deck Shelter (DDS) Operations

Because Dry Deck Shelter DDS operations represent a hybrid of normal air diving and submarine atmosphere exposure, air purity questions for such missions fall outside the scope of current U.S. Navy documents. Thus the NMRI was tasked to develop purity standards for divers air derived from submarine air banks. This report provides screening procedures for verifying purity of divers breathing air during DDS operations. These guidelines have been previously promulgated to the Fleet COMNAVSEASYSCOM ltr 10560 00C32101 of 16 July 86 but only now are being formally published to facilitate reference and distribution. This published version is identical in all aspects to that previously distributed to COMNAVSEASYSCOM and the Fleet.
