This study develops empirical relationships between several indices of heat stress derived from a series of studies in 14 representative, hot industries. With particular emphasis on Wet Bulb-Globe Temperature, the analysis verifies and supplements certain relationships between heat stress indices developed by other investigators. Because of its large industrial data base, the study also provides a reliable basis for interrelating heat stress indices in future standard-setting procedures.
