Title: Evaluation of the KIN and DUI Passive Thermal Survival Systems: Deep Dive 92.
Author: Russell, KL
Abstract: In the event of power toss to a hyperbaric or personnel transfer capsule, hypothermia can rapidly ensue if thermal protection is not provided. A simulated cooling profile, adopted from a Swedish Navy trial, was used to evaluate the effectiveness of the Diving UnLimited international (DUI) and Seaforth Kinergetics (KIN) passive thermal protection systems at 257 msw. Three data points were obtained for each system. The ability to protect subjects from heat toss, oxygen and carbon dioxide levels within the systems, and functional considerations were addressed. One subject remained in the KIN system for 12 hours, the maximum duration of the study. AIL other trials were terminated due to subject discomfort, rather than tow core temperatures or other termination criteria. If the DUI system is used with additional protection from the deck (a mattress), and the KIN with baffles inflated, it appears that greater than 12 hours thermal protection can be expected at 257 msw in a cooting profile scenario. Neither system appeared to provide superior thermal protection over the other if these guidelines were followed. Adequate oxygen levels were supplied by the DUI at 257 msw in a 0.46 ATA PO, environment, even though workup experiments showed oxygen levels within the DUI system might be a problem due to the to-fro design of the canister....
