Ergonomics is the science of fitting the job to the worker doing that job. The goal of ergonomics is to reduce a worker's exposure to musculoskeletal disorder (MSD) risk factors by changing the design of a workstation or the way a job is performed, allowing workers to rotate through different jobs, or providing personal protective equipment (PPE). While the Clinton-era ergonomics standard was revoked, OSHA will cite ergonomics violations under the General Duty Clause.
