摘要: Publisher Summary In determining what protective equipment or safety and health precautions to take in extreme thermal environments, it is useful classify the factors existing environment which person affected most often exposed, including air temperature, radiant wind velocity, water vapor pressures. It possible minimize adverse effects of hot environments by allowing workers time acclimatize their environment, characterized an increased sweat output a lowering pulse rate, internal deep body temperature response stress. The performance sedentary tasks with low metabolic heat should be avoided temperatures as difficult provide sufficient insulation. approach problems associated such industries farming, dock work, building very parts world will have physiological behaviorally based, work adapted within limits physiology training, education, improvements standards.
