Evaluation of stresses of exposure to heat.
Department of Industrial Environmental Health Sciences, Graduate School of Public Health, University of Pittsburgh 1976 Jan; :1-14
A report is presented on the reliability of the wet bulb globe temperature, or WBGT, index, numerical coefficients describing safe limits for heat exposure, and the heat stress meter or Hatch cylinder. High humidity and low air movement produce more physiological strain than the other conditions in their respective WBGT grouping. The numerical coefficient for safe heat exposure is apparently underestimated by about 30 percent in a 36 degree centigrade environment. The coefficient for a clothed individual is about 62 percent of that when seminude. Modifications in the Hatch cylinder could eventually yield a model to replace man.
