Abstract

                                                                                                    Background and Objectives: The concept of safety culture is improving safety in workplaces. Recent focus on the management role in the causes of accidents has led to greater attention to the concept of safety culture. Various tools have been developed to measure safety culture in different studies. The purpose of this paper was to provide a standard tool and validate a customized questionnaire for assessing safety culture in the petrochemical industry.

Materials and methods: This cross-sectional study was conducted in the petrochemical industry in Iran during autumn 2014. The studied subjects consisted of 44 petrochemical workers with registered accidents from 2011 to 2014. A questionnaire including 37 questions was distributed to staff members and the reliability and validity of questionnaire were assessed. In order to confirm the factor analysis, the Kaisor-Meyer-Olkin (KMO) and Bartlett’s sphericity tests were used. Ethical considerations in this study were adhered based on the Helsinki guidelines.

Results: The results of reliability analysis of questionnaire showed that Cronbach’s alpha reliability coefficient was 0.95. The results of KMO (0.72) and Bartlett’s sphericity test (x²=1300.81, p<0.001) suggested that factor analysis was appropriate method for assessing the factor structure of the questionnaire. There were significant positive correlations between all features of safety culture questionnaire.

Conclusion: This study has found that the customized safety culture questionnaire had 7 effective components and the validity values indicated that this questionnaire may be appropriate tool for assessing safety culture in petrochemical industries.
