Abstract

Background: The objective of the study was to investigate the physiological responses of construction workers labouring in thermally stressful environments in the UAE using Thermal Work Limit (TWL) as a method of environmental risk assessment.

Methods: The study was undertaken in May 2006. Aural temperature, fluid intake, and urine specific gravity were recorded and continuous heart rate monitoring was used to a

The development of a rational heat stress index called thermal work limit (TWL) is presented. TWL is deŽ ned as the limiting (or maximum) sustainable metabolic rate that euhydrated, acclimatized individuals can maintain in a speciŽ c thermal environment, within a safe deep body core temperature (< 38.20±C) and sweat rate (< 1.2 kg/hr¡1). The index has been developed using published experimental studies of human heat transfer, and established heat and moisture transfer equ
