Abstract: Human factors have contributed to the causes of several accidents. The physiological parameters change law of labor employees before and after fatigue is researched in this paper. The purpose of this research is to find the relationship between physiological parameters and fatigue, design corresponding fatigue monitoring and early warning system, reduce the accident rate and optimize the working environment. The labor employees’ heart rate, RR interval, respiration rate and blood pressure under fatigue state are determined in the laboratory. The change law of labor employees’ heart rate, RR interval, respiratory rate and blood pressure are analyzed based on the paired samples t test by using SPSS software. The results show that labor employees’ heart rate and RR interval have no significant difference before and after fatigue. Labor employees’ respiration rate has significant difference before and after fatigue: the respiration rate decreased after fatigue. Labor employees’ blood pressure has significant difference before and after fatigue: blood pressure of labor employees after fatigue can be elevated. The results provide a richer theoretical and practical basis in what criteria are used to determine the fatigue. It has important significance in the safety management field and accident prevention.
