Abstract : The Navy Experimental Diving Unit (NEDU) evaluated a modified AGA Full Face Mask (FFM) with open circuit/closed circuit switchover capability for use with U.S. Navy closed circuit UBA. This FFM, designated Interspiro OC1 FFM, was found to function acceptably with both the MK 15 and Draeger LAR V UBAs, and provides adaptability to the MK 16 UBA should a need be identified. This mask provides an open circuit emergency bailout capability as well as a means of extending dive duration beyond the limitations of the closed circuit UBA.
