- Abstract
- The study examined the capabilities of three technologies (a liquid cooled undergarment, a thickly-ribbed vest of hydrophylic nylon, and an air vest) to alleviate thermal strain in personnel working in Explosives Ordnance Disposal (EOD) clothing under environmental conditions of 18C @ 40% relative humidity (rh), 34C @ 40% rh, and 34C @ 80% rh. Simulated EOD tasks consisted of treadmill walking (10 min), unstacking/carrying/stacking weighted boxes (10 min), and a rest period (15 min) with the EOD helmet and jacket removed repeated for a target duration time of 90 min. Physiological data included rectal temperature, skin temperature, heart rate, sweat production and evaporation, metabolic rate, and subjective evaluations of thermal comfort and perceived exertion. The results indicated that wearing the EOD suit produces significant increases in thermal physiological strain over performing the same tasks in a standard station uniform. TRUNCATED
