Abstract
Data from two steel mills were used to develop a model to estimate current worksite environmental heat stress from outside meteorological observations. The final model developed to predict worksite wet bulb globe temperature (WBGT) utilizes locally measured dry bulb temperature (DB) and local psychrometric wet bulb temperature (PWB). It is contended that this model will prove useful in establishing safe limits for exposure to heat stress via the development of a heat stress index. The main finding of the study is that WBGT values can be estimated better in areas away from the open hearth steel furnace than in areas near the furnace. This is considered problematic since WBGT values are highest near the furnace, and, in fact, some workers are in this area for substantial periods of time. One explanation for the WBGT variability for fairly constant outside conditions is the change in temperature produced by process operations. In future analyses, attempts should be made to analyze data by different process times.
