Underwater Purging Procedures for the Draeger LAR V UBA (Underwater Breathing Apparatus).

Abstract

The U.S. Navy has identified a need to switch to the Draeger LAR V closed-circuit oxygen Underwater Breathing Apparatus from open-circuit air while underwater. The revised purge procedure described in NEDU Report 5-84 and subsequently approved for fleet use was tested only at 1 ATA. This study was carried out to develop a purge procedure suitable for use underwater. Three different purge procedures were tested. The incluence of diver position in the water during the procedure and the type of open circuit air facemask regulator configuration used prior to switching to the LAR V were also examined.
