Ergonomics is the science of fitting workplace conditions and job demands to the capabilities of the working population. A major component of ergonomics is the development of industry-specific and task-specific guidelines to reduce and prevent workplace musculoskeletal disorders (MSDs). These voluntary guidelines are tools to assist employers in recognizing and controlling ergonomics-related risk factors. Employers in other industries for which guidelines have not been developed may find useful information in these guidelines for implementing their own ergonomic programs.
