A Study of the Causes of Occupational Accidents in Manufacturing Companies

摘要

Background: Studies have found that several individual and organizational factors influence the occurrence of accidents. Researchers have also highlighted the need for the development of new accident models. The main aim of this study was to assess the contributing causes of occupational accidents using a questionnaire. Methods: A total of 365 managers and employees participated in the current study from 9 manufacturing companies located in the northwest of Iran. A questionnaire comprising 100 accident causes was used to gather the required data for this study. Results: Exploratory factor analysis (EFA) yielded 14 factors contributing to accidents, and confirmatory factor analysis found satisfactory fit indices for the EFA model. The participants reported unsafe acts as the most important factor for the occurrence of accidents. A t-test revealed that participants who received safety training experienced fewer occupational accidents than other respondents. The one-way analysis of variance showed that the companies significantly differed in the perception of accident causes. Structural equation modeling indicated that organizational-managerial factors had a larger effect on individual factors than external factors. Conclusion: The results indicate that providing safety training is necessary to control the employees' unsafe acts. Managers of the companies should pay special attention to the organizational factors affecting the occurrence of accidents. The findings of this study might help the managers to develop more targeted countermeasures for reducing occupational accidents.
