Re-Evaluating the DSI Contaminated Water Diving Kit's Ability to Prevent Water Aspiration into the MK 21 MOD 1 UBA
Abstract
A contaminated water diving system (CWDS) protects a diver from exposure to water-borne toxic, volatile, corrosive, or microbial agents. This report followed up on a previous report that evaluated the ability of the Diving Systems, International (DSI, Santa Barbara, CA) contaminated water diving kit to prevent water aspiration into the MK 21 MOD 1 underwater breathing apparatus (UBA). These kits are comprised of double flapper exhaust values and a secondary water dump value. Testing was conducted to a maximum depth of 60.6 msw (198 fsw) , using respiratory minute volume (RMV) levels as high as 90 liters per minute (LPM). The performance of the values was continuously monitored using a video camera mounted inside the UBA during testing. The values maintained watertight integrity until the inspiratory pressures produced by the mechanical breathing machine far exceeded those that a diver can produce. Thus, the contaminated water kit provides working divers definitive protection from water aspiration. Therefore, NEDU continues to recommend the DSI contaminated water kit for Navy use in the MK 21 MOD 1 UBA.
