Heat and resulting humidity buildup inside protective suits cause discomfort for first responders and impair performance. The extent of the effects can be as severe as heat stroke, heart attack or even death. The use of a cooling garment under protective clothing may improve these adverse conditions and help the wearer concentrate on the task. Current military operations in Iraq and Afghanistan represent another application for cooling garments. The purpose of this study was to compare physiological and perceptual responses of subjects wearing two prototype portable liquid cooling systems vs. no cooling under controlled environmental conditions. The prototype vests were identical except for tubing. Flexible PVC tubing was in one vests and a less flexible but more conductive tubing was used in the second vest. The vests and no cooling treatment were worn under level A and Level B suits with full gear. A 30 minute protocol was devised to closely simulate typical incident activities of first responders. Environmental conditions were controlled at 80 F and 50% relative humidity. Dependent variables included: core and skin temperatures, sweat rate, heart rate, RH and temperature of the microenvironment and perceptual data. Six volunteer male subjects who had experimental hazmat training (age range: 20--41) participated in this study. The results showed that the cooling garments were effective in providing relief during the testing. The subjects' perception of cooling relief agreed with the physiological data. The two prototype cooling vests positively affected skin temperatures at two locations, chest sweat rate, microclimate temperature and humidity and perceived temperature and humidity. Both physiological measurement data and perception data indicated that there were no significant and consistent differences between the two cooling vests.
