Abstract

Human safety protection in hot environments is required in many fields, such as high-temperature industrial operations and fire fighting. This paper presents a method to estimate human safety in hot environments. The method combines the bio-heat theoretical model and experimental simulations. The hot experimental environment uses a high-temperature cabin heated by an infrared thermal radiation board. The body temperature and required perspiration rate are calculated by the theoretical model for the real-time experimental parameters. The balance between the warming and the sensible heat released by perspiration is simulated using a NEWTON thermal manikin. The bio-heat response of the body temperature and the perspiration rate due to the heating is studied for 30-40 ^oC thermal environments. The human safety is estimated for both hyperthermia and dehydration. The results show that this method can accurately simulate the human thermal physiological response and estimate the human safety status in hot environments.
