title: Thermal stress: the need for an international standard.
abstract: There is a universal need for a single index of heat stress. Such an index would make it possible to standardize thermal working conditions on a global basis. It is proposed that the WBGT index, corrected for energy expenditure and airflow, can fill this need. A review of available indices suggests that for all practical purposes the WGBT index is most likely to find universal acceptance.
