Introduction: Based on existing knowledge and theory of the biomechanics and epidemiology of distal and upper extremity disorders, a semi-quantitative job analysis methodology was developed. The petrol pump workers who have the repetitive activity of upper limb by holding and keeping the nozzle at the petrol pump station. This repetitive activity increases the tension on the muscles, ligaments, and other soft tissues of the musculoskeletal system. This activity is carried out in standing posture. Objective: The purpose of the present study is to know the prevalence of upper limb deformity in petrol pump workers. Methods: Samples were assessed using Rapid Upper Limb Assessment (RULA) tool. Results: 60% of the population were found to be under medium risk, 14%of the population had a higher risk of developing a deformity and 26% had negligible or at low risk. Conclusion: Proper ergonomic care must be undertaken in the high-risk category and appropriate ergonomic advice should be given to the workers to prevent them from becoming vulnerable to upper limb deformities.
