Evaluation of the KMS 48 Replacement Full Face Mask with the Emergency Breathing System for Use with MK 16 MOD 1 Underwater Breathing Apparatus

摘要

Navy Experimental Diving Unit (NEDU) was tasked by references (1) and (2) to test and evaluate the MK 16 MOD 1 underwater breathing apparatus (UBA) for use as an emergency breathing system (EBS) in conjunction with the KMS 48 full face mask (FFM). Testing was designed to assess the abilities of the KMS 48 FFM and the MK 16 MOD 1 to perform as an EBS during unmanned and manned open water dives to the maximum operational working depths for each breathing medium: 190 feet of seawater (fsw) 58.2 meters of seawater (msw) with nitrox (N2O2), and 300 fsw (91.9 msw) with heliox (HeO2).
