||WBGT clothing adjustments for four clothing ensembles under three relative humidity levels

||Threshold limit values for heat stress and strain are based on an upper wet bulb globe temperature (WBGT) for ordinary work clothes, with clothing adjustment factors (CAFs) for other types of clothes. This study investigated CAFs for various types of coveralls against a baseline of cotton work clothes and examined the potential effect of relative humidity. A climatic chamber was used to slowly increase the level of heat stress by increasing air temperature at three levels of relative humidity (20%, 50% and 70%). Study participants wore one of five ensembles while walking on a treadmill at a moderate metabolic rate. Physiological and environmental data were collected. CAFs are proposed for each type of coverall.
