Abstract
An experimental personal cooling ensemble was evaluated for its ability to cool four subjects exposed to varying degrees of thermal stress. Subjects dressed in complete chemical warfare protective clothing ensembles were exposed to both moderate (29.5 degrees C, 50% R.H.) and severe (35 degrees C, 75% R.H.) hot climatic conditions for 2.5 hours. The experimental sessions consisted of two exposures to each condition; one as control, the second with the personal cooling system. Physiological data recorded throughout the experiment showed that the cooling system was effective in preventing body heat storage under the moderate experimental parameters and that it reduced heat storage by approximately 65% during the more severe conditions.
