A comparison of three observational techniques for using postural analysis in a cable factory چکیده
Work-related musculoskeletal disorders (WMSD) which are related with repetitive and demanding working conditions continue to represent one of the biggest complications all over the world. Assessment of exposure levels to WMSD risk factors can be an appropriate base for planning and implementing interventional ergonomics programs in the workplace. This study is focused on posture analysis of a cable manufacturing company workers. The study was conducted on 03 workers engaged in different process of manufacturing. The different activities of the workers were recorded by video and still photography, and these images were used for analysis. Posture analysis tools RULA, REBA and QEC were used. The results of RULA showed that about 33% of the workers were under high risk level and needed a necessary action immediately. About 3.73% of the workers were under medium risk levels and about 53% of the workers were at lower risk levels. The results of REBA have shown that about 5.73% of the workers were under very high risk levels and required immediate change. About 33% of the workers were at high risk levels and a change is necessary soon, and 3573% of the workers were at medium risk levels. According to the QEC method of assessment, it was found that .73 of the workers needed no corrective measures. About 33% of the workers needed additional examination and 3573% of the workers were at high risk and required immediate change. It can be concluded that there are ergonomic deficiencies in the planning and work approaches. A significant proportion of the workers are working in high risk postures. Therefore, the workers are under moderate to high risk of WMSDs. The current study suggested a suitable implementation of ergonomics interventions program with awareness and training among workers to reduce the risks of WMSD.
