ارزیابی نیروی وارد بر کمر هنگام جا‌به‌جایی دستی بار به روش Utah در کارگران ساختمان‌سازی شهرستان همدان در سال 1394: یک گزارش کوتاه

Background and Objectives: Manual load handling is one of the several factors causing work-related musculoskeletal disorders in construction industry and causes serious issues with major economic consequences. The aim of this study was to investigate the forces exerting on the back of building construction workers in the manual load handling tasks. Materials and Methods: This cross- sectional study was carried out among 100 building construction workers in 2015, who were assigned the load handling tasks and totally 955 direct and indirect observations in four tasks and in the five building construction workshops were assessed by Utah method. Data were analyzed using Pearson's correlation test and one - way ANOVA. Results: The amount of exerted force on the back of the workers is compared with NIOSH (National Institute for Occupational Safety and Health) standard (700 lb). Exerted force (Fc) on the back was less than permissible level in all workers. In this study, the average exerted force on the back of workers among different tasks levels by one - way ANOVA showed that there was not a significant difference   among them (p =0.423 ( Conclusion: Based on the findings of this study building construction workers were exposed to risk factors that cause pressure on the intervertebral disk L5/S1. Using Utah method as a simple tool and quick screening in order to obtain compressive force on back in manual material handling is useful.
