There are no state laws requiring employers to have a clinic at the worksite or to keep a doctor or nurse on call to treat workplace injuries. However, the Washington Industrial Safety and Health Act requires every employer to ensure the ready availability of medical personnel for advice and consultation and that when an infirmary, clinic, or hospital is not within close proximity to the workplace, there is a person (or persons) who is adequately trained to render first aid (WA Rev. Code Sec. 49.17; WA Admin. Code Sec. 296-800-150 ).
Washington follows the federal OSH Act requirements for medical treatment in the workplace. There is additional information and a description of the basic elements of an effective medical treatment program.
