Development and validation of the predicted heat strain model
(2001) In Annals of Occupational Hygiene 45(2). p.123-135- Abstract
- Eight laboratories participated in a concerted research project on the assessment of hot working
conditions. The objectives were, among others, 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 International Standard ISO 7933 Standard (1989). 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... (More) - Eight laboratories participated in a concerted research project on the assessment of hot working

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 collected
from the partners. The Pearson correlation coefficients between observed and predicted
values were equal to 0.76 and 0.66 for laboratory experiments and 0.74 and 0.59 for field
experiments, respectively, for the sweat rates and the rectal temperatures. The change in
sweat rate with time was predicted more accurately by the PHS model than by the required
sweat rate 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. ã 2001 British Occupational Hygiene Society.
