Abstract Background & Objectives: Musculoskeletal disorders are one of the major causes of occupational disease in the work places. Prevention of these disorders requires assessment and improvement of working conditions by ergonomics techniques. This study aimed to assess ergonomic risk factors for musculoskeletal disorders construction worker using PATH. Material & Methods: This is a descriptive – analytical study. Work status of 60 construction workers were evaluated using the PATH. Data analysis was performed by SPSS 16 statistical software and presented with general linear model and descriptive statics. Results: from three successive jobs of building Foundation, hard work and joinery have been selected. Labors age was 30/8 ± 10/4 years and the average work experience was 10/6 ± 5/6 years. The trunk posture in the work procedures of the study showed a statistically significant difference) (.Trunk and legs status assessment showed that neutral state labors make up about 50% of the time. In most jobs, about 80% of labors work in a neutral position and about 51% of labors did not bearing weight during their work. Conclusion: Further studies aimed at assessing job offers, ergonomic tools and design tools and teaching labors in proper lifting techniques can be effective in reducing musculoskeletal disorders
