A valid method for comparing rational and empirical heat stress indices
No single heat stress index has gained universal acceptance within the past 20 years., despite extensive research. It is currently difficult to directly and quantitatively compare the many rational and empirical indices that are available, which results in confusion and a reluctance to change to a different index. A method is developed using the concept of limiting metabolic rate which allows ...

Hydration status of expatriate manual workers during summer in the Middle East
Background: Implicit in all indices used for risk assessment in the prevention of heat stress is the assumption that workers arc healthy and well hydrated; studies in Australian mine workers have shown that this is not the case. Where workers arc poorly hydrated, the level of protection offered by management strategies based primarily on environmental monitoring is compromised. Objectives: To ...

Empirical validation of a new heat stress index
Thermal stress is a well-recognised health hazard in the workplace. In addition to the health deficits, working in the heat can impact significantly on the productivity of some industries which are located in harsh environments. A long-standing dilemma in OHS has been the specification of what constitutes a safe working environment. The current indices used to evaluate the environment are either ...
