Abstract

Background and Objective: Manual materials handling (MMH) by lifting, carrying, lowering, pulling, and pushing is very common in work environments. The aim of this study was to determine the prevalence of musculoskeletal disorders and to compare the evaluation of MMH using SNOOK TABLES and National Institute for Occupational Safety and Health (NIOSH) lifting equation in stone cutting workshops.Materials and Methods: This cross-sectional study was carried out among 100 workers in stone cutting workshops, 2017. SNOOK TABLES, NIOSH lifting equation, and General Nordic questionnaire were used to assess MMH tasks and the incidence of musculoskeletal disorders. Finally, these two methods were compared in terms of agreement on risk assessment.Results: The results showed that 48% of the workers experienced pain at least once during the past year with highest frequency in the low back (48%), elbows (44%), and shoulders (36%). Weights of the loads were more than the recommended weight limit (RWL) obtained from the NIOSH equation and SNOOK TABLES. Regarding the results of both methods, the risk level was high in different workshops. The comparison of two methods showed that their accuracy for risk assessment were quite different.Conclusion: The results showed high prevalence of musculoskeletal disorders among workers. Therefore, ergonomic measures are necessary to improve working conditions. It seems that NIOSH lifting equation has higher accuracy and stricter than SNOOK TABLES in the risk and RWL estimation.
