Title Evaluation of heat load risk during work in hot environments
Original title Evaluation du risque de contrainte thermique lors du travail en ambiances chaudes [in French]
Bibliographic information 2001, Vol.XXXVIII, No.3, p.101-112. Illus. 31 ref.
Abstract The objective of this project was to coordinate the work of the main European research teams in order to develop and improve methods to assess the risks encountered during work in hot conditions. Methods and formulas were developed that take into account the dynamic effects associated with forced convection and the pumping effect associated with body movements and exercise, as well as more severe conditions in terms of radiation, humidity and different clothing. Criteria concerning the maximum increase in core temperature and the acceptable water loss, for acclimatized and non-acclimatized subjects, were reviewed and updated. These limits intend to protect 95% of the population. A strategy was developed to assess the risks in any working situation with varying conditions of the climate, of metabolic rate or of clothing. A methodology was developed for observation and analysis. The Predicted Heat Strain model developed as part of this project is presently proposed for the revision of the ISO 7933 standard.
