Title Effects of thermal environment and chemical protective clothing on work tolerance, physiological responses, and subjective ratings
Bibliographic information Apr. 1991, Vol.34, No.4, p.445-457. Illus. 49 ref.
Abstract This study examined the physiological and subjective responses of nine men who completed exercise tests while wearing two types of protective ensembles (light work clothing and a self-contained breathing apparatus (SCBA), and a two-piece chemical protective ensemble (CHEM) with SCBA), in each of three thermal environments. The total worktime was found to be significantly shorter in the hot environment while wearing the CHEM ensemble. The mean maximum physiological values and subjective responses also indicated significant differences due to thermal environment and/or ensemble. Results suggest that when ensembles similar to the CHEM are used in hot environments, workrate should be reduced, work periods shortened and rest periods extended.
