Assessment of the risk of arm repetitive movements among workers in the motor vehicle glass finishing industry

The aim of the study was to evaluate risk associated with biomechanical overload of the upper limbs in workers exposed to repetitive movements, employed to the finishing of glasses for motor vehicles. The risk assessment was performed using the OCRA method (OCRA index for every worker and Check-List OCRA for every workstation) and the results have been distributed for exposure levels. Altogether the results suggested the existence of risk associated with repetitive movements of the upper limbs and different risk classes (high, medium, light, very light). OCRA index and Check-List OCRA values showed together high risk in the workers with age and employment duration great (respectively 20.68% e 27.58% of workers), with especially involvement of the women, employed to jobs with high frequency.
