Ergonomic Assessment of Musculoskeletal Risk Factors at Four Mine Sites

This study examined musculoskeletal injury risk at four mining sites: underground coal, underground limestone, surface copper, and surface phosphate. Each site offered opportunities to investigate musculoskeletal disorder (MSD) injury risks and how those risks might be identified and categorized. The National Institute for Occupational Safety and Health (NIOSH) worked with these sites to (1) identify work activities that showed evidence of MSD injury risk, (2) examine physical risk factors that can lead to MSDs for a handful of work tasks at each site, and (3) develop a set of ideas for problem-solving to help reduce risk factors for examined work tasks.
