Abstract:

The physiological responses of two volunteer subjects exposed to an extreme cold water environment 0C while wearing the 316 inch Chloroprene Wet Suit, 18 inch Chloroprene Wet Suit, and the Polyvinyl Chloride Wet Suit were investigated under two conditions of use constant immersion-flotation COND I and immersion-flotation for a two-minute period followed by raft occupancy COND II. In view of exposure duration ranging from 0.5-1.0 hr and from 2.0-3.0 hr under CONDITIONS I and II, respectively, the results indicate that survival and tissue damage protection is afforded, within expected limits of time under both emergency conditions for search and recovery, by any of the clothing assemblies tested. It is recommended, therefore, that the 18 inch Chloroprene Wet Suit be considered as the most acceptable on the basis of such physical characteristics as reduced weight and bulk.
