Abstract

Personnel working in industry can encounter hot and humid conditions where uncompensable heat loads are experienced; an inability to dissipate stored heat increases the risk of developing a heat illness. In order to minimise the incidence of heat illnesses, several heat stress reduction interventions have been developed which aim to allow for safe repeated bouts of exposure to high thermal heat loads. These vary from modification of the working environment, wearing of personal protective equipment designed to cool, heat stress indices and/or hydration regimens. Despite these interventions, personnel still experience heat stress related illnesses. Consequently, the overall aim of the thesis was to quantify the cooling capacity of an ice slurry beverage, and to measure the physiological responses of this simple, easily implementable and cost effective cooling intervention.
