Abstract. Work-related musculoskeletal disorders have posed a concern on both the individuals health and industries. In India majority of workforce are in the informal economy, also known as unorganised sector in the country. Among the unorganised sector, stone quarry, cutting and polishing units are where a large number of workers are involved and prone to various occupational injuries and health hazards. The present study focuses on occupational health and safety deficiencies in the stone quarry, cutting and polishing industry in North Karnataka. The study was conducted using Nordic Questionnaire, Postural analysis using REBA method and on use of PPEs and other welfare activities. The collected data was analysed statistically. The results indicated prevalence of WRMSDs in both stone quarry workers and stone cutting and polishing workers. The REBA scores showed a significant high risk among majority of workers. Physical work environment factors like noise and heat were also measured, and found to be above the acceptable levels. It is concluded that the working conditions in stone quarries, cutting and polishing units’ needs to be improved. The postures adopted by workers are mostly in higher risk categories and need to be changed urgently. The noise levels are above the permissible limits and the use of PPEs should be encouraged. Overall the productivity of these industries can be improved by incorporating the ergonomics and OHS recommendations.
