Proposing a customized model of safety culture and behavior in a car manufacturing company


Background: Work-related accidents and illnesses are a great concern in developed countries. This study was designed to develop a customized model of the safety culture and identifying effective factors in a car manufacturing company.

Methods: The present descriptive analytical study was conducted based on retrospective and field studies in a car manufacturing company. In order to present a new customized model of safety culture questionnaire, the study was designed in three phases: 1) offering a customized model 2) providing a customized questionnaire 3) field study.

Results: A total number of 619 cases completed the questionnaire 321 damaged and 298 undamaged people). The Cronbach's alpha for the questionnaire was 0.855. With the exception of the safety rules and conditions, the damaged population markedly acquired more points for the whole questionnaire in comparison with their undamaged colleagues, though, this difference was statistically significant (P<0.05) only in 7 questions. Moreover, the correlation of safety culture components in damaged personals and undamaged one or combination of both showed that approximately all components present positive correlations (P<0.05 or P<0.001).

Conclusions: The use of the customized model and questionnaire in car manufacturing industry is the marked feature of the present study. The result of the mentioned factors demonstrated that the safety culture of the damaged population is higher than undamaged one. Thus, it might be stated that the occupational accident is the milestone to evaluate the safety culture.
