Recently, due to global warming and. the heat-island effect, more and more people are exposed to danger of heat disorder. The hot thermal environment can be evaluated by various indexes, such as new Standard Effective Temperature (SET^*) using the 2-Node Model (2NM), Wet Bulb Globe Temperature (WBGT), Predicted Heat Strain Model (PHS Model) and so on. The authors aim to develop a safety evaluation approach for hot environments. Subject experiments are performed in a laboratory to comprehend the physiological response of the human body. The results are compared with the computed values from the 2NM and PHS models and modified the sweating model in 2MN in order to take account the relationship with metabolic rate. Additionally, this new sweating model was applied to evaluation for thermal safety for hot environment.
