A study of physiological and psychological effects of heat exposure among steel industry workers was conducted in a steel industry located in Gebeng, Kuantan, Pahang. This study involves 20 steel industry workers who were exposed to heat sources. The purpose of this study are to determine the physiological (body temperature and heart rate) and psychological (fatigue feeling) effects of workers when they are exposed to sources of heat in hot working environment.

There are significant differences between body temperature before and after working (p=0.003). However, for heart rate, the increment is not significant (p=0.838).

Furthermore, the relationship between body temperature with WBGT indoor are weak (r = 0.268, p > 0.05). However, the relationship between heart rate with WBGT indoor are strong (r=0.543, p<0.05).

Exposed to hot working environment can results in variety of heat-related illness and safety problems. A study of physiological and psychological effects of heat exposure among steel industry workers was conducted in a steel industry located in Gebeng, Kuantan, Pahang. This study involves 20 steel industry workers who were exposed to heat sources. The purpose of this study are to determine the physiological (body temperature and heart rate) and psychological (fatigue feeling) effects of workers when they are exposed to sources of heat in hot working environment. The factors that contribute to heat exposure among the workers were identified first.
