There are no state laws requiring employers to have a dispensary at the worksite or to keep a doctor or nurse on call to treat workplace injuries. Wisconsin is not a state-plan state; it does not have a safety and health plan to regulate private sector (private businesses and nonprofit organizations) workplaces. Therefore, the federal Occupational Safety and Health Act (OSH Act) governs workplace safety and health in the private sector.
The federal law requires every employer to ensure that medical personnel are readily available for advice and consultation and that when an infirmary, clinic, or hospital is not within close proximity to the workplace, there is an individual (or individuals) who are adequately trained to administer first aid. Employers are responsible for making decisions about the details of emergency medical care in their workplaces, depending upon the size, the kinds of hazards present, the history of accidents, and the costs of various options (29 CFR 1910.151).
Public employers. Wisconsin does have safety and health statutes that regulate the public sector (government agencies, public schools) (WI Stat. Sec. 101.055; Sec. 101.11). The law's medical treatment standards are identical to those of the federal OSH Act. The law is administered by the Department of Commerce/Safety and Buildings Division.
There is additional information and a description of the basic elements of an effective medical treatment program.
