Abstract
This assessment of intermittent work in hot environments was conducted to demonstrate the usefulness of modelling and simulation to the Canadian Forces. Analytical predictions of work and rest durations were made using a thermal physiology model and a human performance modelling tool, IPME. The results indicate that current guidelines could be extended to cover work in more extreme climatic conditions, including WBGT(C) values into the mid 40s, and that the published CF work and rest durations may be too conservative in some conditions. The available time for this study did not permit validation of the predictions by empirical studies, but an approach is presented for a more comprehensive investigation that would lead to a validated update to the current guidelines for commanders.
