Thermal work limit ( TWL ) is an index defined as the maximum sustainable metabolic rate that well-hydrated, acclimatized individuals can maintain in a specific thermal environment within a safe deep body core temperature (< 38.2 °C or 100.8 °F) and sweat rate (< 1.2 kg or 2.6 lb per hour). The index is designed for self-paced workers and does not rely on estimation of actual metabolic rates. The index has been introduced into the United Arab Emirates and Australia , resulting in a substantial fall in the incidence of heat illness in the latter.

21-477: A particular thermal environment in order to keep the body within safe physiological limits. The TWL is an integrated measure of the dry-bulb , wet-bulb , wind speed , and radiant heat . From these variables and taking into consideration the type of clothing worn and the acclimatization state of the worker, the TWL predicts the maximum level of work that can be carried out in a given environment without workers exceeding
28-421: A safe core body temperature 38.2 °C (100.8 °F) and sweat rate. Sweat rates are also calculated, so the level of fluid replacement necessary to avoid dehydration can be calculated. The thermal work limit algorithm builds on work originated by Mitchell and Whillier who developed an index "specific cooling power", which subsequently became known as "air cooling power" (ACP). The TWL has been included in

TWL and its management protocols have been introduced into several industrial operations where workers are subject to thermal stress . Since the introduction of TWL-based policies in
