  • Slide Show Notes Welcome to the training session on ergonomics in industrial work areas. This session will look at some of the basic principles of ergonomics so that you can use a commonsense approach to working safely. In particular, the information presented here will focus on musculoskeletal disorders, or MSDs, and how ergonomics helps prevent them.
