Tech 045 Safety & Allowances Tips

 

What is an "ergonomic injury"?
Input from the recent ergonomics forums demonstrated to OSHA that there are a wide variety of opinions on how the Agency should define an ergonomic injury and that the definition adopted by OSHA depends on the context. Ergonomic injuries are often described by the term "musculoskeletal disorders" or "MSDs." This is the term of art in scientific literature that refers collectively to a group of injuries and illnesses that affect the musculoskeletal system; there is no single diagnosis for MSDs. As OSHA develops guidance material for specific industries, the agency may narrow the definition as appropriate to address the specific workplace hazards covered. OSHA will work closely with stakeholders to develop definitions for MSDs as part of its overall effort to develop guidance materials.
