The use of physiological measurements, heart rate and oral temperature, for evaluating a heat stress situation in an industrial plant is described. In contrast to evaluation of hot jobs by environmental measurements and subjective evaluation of metabolic rate, the technique used with the WBGT criteria, evaluation of heat strain by measurements of the individual's heart rate and oral temperature is simpler, less expensive, less restrictive and more protective. A description of the technique involved for an industrial job along with suggested heart rate recovery criteria are included.
