Title: Evaluation of a Diver Cooling System for Use With Personal Protective Equipment in Contaminated Water Diving
Author: Leyva, FF; Goehring, GS
Abstract: Current Navy recommendations for diving in contaminated water include wearing a vulcanized rubber dry suit mated to a MK 21 diving helmet to isolate the diver from the contaminated environment. However, even in situations (e.g., visible oil spills, noxious fumes, and sewer outflows) where the need for protective gear is uneguivocal, thermal stress from working in a warm environment often precludes the use of such gear. The purpose of this study was to identify and evaluate a commercially available diver cooling system through field trials for overall effectiveness, comfort, durability, and ease of use in and of incorporation into Navy diving practices. Ten dives were completed over 2 days in November 2003 at Naval Base Guantanamo Bay, Cuba. No systematic testing was performed. During dives, divers were asked to report on their level of thermal stress, and after diving, each diver completed a feedback survey. Overall the suit performed well in cooling the divers, despite temperatures greater than 100 deg F by heat index. Divers found the suits comfortable and easy to use, with minimal change to normal diving procedures. Problems were found with overly buoyant cooling hoses and hose connectors that detached too easily. Despite these shortcomings, however, all divers recommended the system for diving in warm environments with maximal protective gear, end we recommend that the Navy consider further evaluation of the suit for inclusion on the ANU List.
