Comparative Human Factors Analysis of the U. S. Navy Mark V. and Mark XII Dive Systems.
Abstract
A series of tests were conducted to assess the suitability of the U.S. Navy prototype Mark XII hardhat diving system as a replacement for the U.S. Navy standard Mark V diving system. The tests combined operational testing with human factors testing to depths of 300 ft under four separate environmental conditions: open tank, hyperbaric chamber, Anacostia River, and open water. Air was used as the breathing medium for shallow depths, with HeO2 substituted as depths increased. Task times were recorded and compared, as well as dressing and undressing times. An equipment evaluation was made by each diver on the Mark XII. An anthropometric study of both systems was performed, measuring range of movements on 14 anthropometric measures.
