| Abstract |
Eight laboratories participated in a concerted research project on the assessment of hot working conditions. The objectives were to co-ordinate the work of the main European research teams in the field of thermal factors and to improve the methods available to assess the risks of heat disorders at the workplace, and in particular the "Required Sweat Rate" model as presented in ISO 7933 standard. The scientific bases of this standard were thoroughly reviewed and a revised model, called "Predicted Heat Strain" (PHS), was developed. This model was then used to predict the minute-by-minute sweat rates and rectal temperatures during 909 laboratory and field experiments. The change in sweat rate with time was predicted more accurately by the PHS model. This suggests that the PHS model would provide an improved basis upon which to determine allowable exposure times from the predicted heat strain in terms of dehydration and increased core temperature. |
