Abstract

Background and aims: the musculoskeletal disorders over a large percent of occupational diseases, therefore, in order to protect workers from such disorders, there is a need to evaluate workers positions at work in different jobs. There are several methods to evaluate risk factors causing work - related musculoskeletal disorders. this study perform on bakers population of four different types of bakeries(Tafton davar,Tafton sonnati, sangak and baget) and we evaluated WMSDs causal risk factors by OCRA Index technique. Methods: In this research four data gathering methods including observational, interview ,questioner and check list were utilized. Totally 423 samples by proportional cluster sampling method collected and we used spss15 soft ware for statistical analysis. Results: The results of this investigation demonstrated that maximum mean value of OCRA index in left and right hands were related to shatery task in sangak bakery (OCRA index=14.99).finally,56.5,67.4,77.3 and 75 percent of all tasks at Tafton davar,Tafton sonnati, sangak and baget bakeries respectively were in the red area also our results showed that only ,left and right hands OCRA index means of nandari , forushandegi and nandara/forushandegi tasks were equivalent. Conclusion: with regarding to this point that major of tasks in the bakery job locate in the red zone therefore attention to this problem is necessary and use of ergonomics controls to eliminate or reduce exposure of workers to the ergonomics stressors associated with the development of WMSDs is recommended.
