Background: Posture is a physical factor identified in occupational musculoskeletal injuries awkward working posture had a strong relation to the causation of musculoskeletal injuries. In sugar-producing factories, workers are directly involved in the production process. Industrial physical activities such as manual material handling (e.g., heavy load lifting, lowering, carrying, pulling, and pushing) and awkward working postures are very common. In this situation, a high rate of WMSDs is expected. Ovako working posture analysis was used for asses the working posture (OWAS). Objectives: To assess working posture in sugar factory workers Methodology: The observational study done on thirty participants working in pravaranagar sugar factory. Working posture was analysed by ovako working posture analysis system (OWAS) Results: The OWAS shows some working posture needs modification and intervention the distribution of action category among trunk. The action category 1(code1) was 26.6%. The action category 2(code2) was 23.3%. The action category 3(code3) was 23.3%. The action category (code4) is 26.6%. The distribution of action category among upper extremity. The action category 1(code1) was of3.33. The action category 2(code2) was 36.6%. The action category 3(code3) is of 30%.The action category (code4) was 26.6%. The distribution of action category among lower extremity. The action category 1(code1) was of 26.6%. The action category 2(code2) was of 20%. The action category 3(code3) is of 30%.The action category (code4) was 26.6%. Conclusion: This study shows that some postures were inappropriate while working and they need to be corrected using ergonomic intervention and work place modifications. Lectures and educations programs should be conducted in sugar producing factories.
