||Fluid losses and hydration status of industrial workers under thermal stress working extended shifts
||Feb. 2003, Vol.60, No.2, p.90-96. Illus. 44 ref.
||This study examined the fluid consumption, sweat rates and changes in the hydration state of 39 male underground miners in northern Australia on extended shifts under significant levels of thermal stress (WGBT>28░C). Urinary specific gravity was measured before, during and at the completion of the working shift. Environmental conditions were measured hourly during the shift. Fluid replacement was measured during the working periods and during the meal breaks. It was found that dehydration did not occur in well-informed workers. Fluid replacement during meal breaks was not significantly increased above fluid replacement rates during work time. Urinary specific gravity was found to be a good indication of hydration status and a practical method for improving workforce awareness and understanding of this important risk factor.
