Investigation of the Relationship between Biorhythms and Occupational Accidents Severity in a Chemical Industry, 2009-2022
Abstract
Introduction: Occupational accidents have several life and financial consequences in industries. Among the causes of accidents, human error and unsafe behavior are known as the most important factors. Studies showed that biorhythms affect human errors and occupational accidents. This study aimed to investigate the relationship between biorhythms and the severity of occupational accidents in the chemical industry. Materials and Methods: This study investigated chemical industry accidents from 2009-2022. After removing the incomplete reports, 279 accidents report was collected. The investigated accidents were classified into two groups major and minor. Information related to the biorhythms cycles was analyzed using Natural Biorhythm software. Data analysis was done using SPSS-24. Results: The investigation of accidents showed that 115 and 164 people were involved in major and minor accidents, respectively. In this study, in the critical state of the intellectual cycle, the number of major accidents was significantly higher than minor accidents (P=0.009). In the investigation of morning shift work accidents, the relationship between the critical state of the intellectual cycle and the severity of accidents was confirmed (P=0.004). We found no significant relationship between physical and emotional cycles with the severity of accidents. Conclusion: The results of the present study showed that the critical days of the intellectual biorhythm are related to the severity of occupational accidents. It is recommended to conduct more studies on different jobs and duties to clarify the exact relationships between the variables.
