Physiological study of occupational heat stress by means of a simple standard laboratory type heat-work test along with an exhaustive study of men at the work site. Data are presented on the actual climatic environment of the work site, the physiological and psychological demands of the job, the daily work-rest regimen, the heat exposure history, the health and nutritional status, the state of body hydration, the non-working physical environment with its seasonal variations, and the non-working activities of the workers. The physiological responses of the men to the standard tests are significantly correlated with the responses elicited by the job and its environment and also reflect the climatic conditions of the living environment. The amount of sweat evaporation required for maintaining body heat balance is calculated for each observed job and is used for quantitative description of the combined heat and work stress. Body heat balance values are calculated both for short term peak exposures and for average eight hour exposures so they can be used for setting acceptable limits both for eight hour time weighted average levels and for peaks above base line.
