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 assess fatigue. Subjects were monitored over 3 consecutive shifts. TWL and WBGT were used to assess the thermal stress. Results Most subjects commenced work euhydrated and maintained this status over a l2-hour shift. The average fluid intake was L. There were no changes in core temperature or average heart rate between day l and .
