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. The Maryland health and safety code has adopted the federal Occupational Safety and Health Act (OSH Act) workplace medical treatment requirements by reference. The law requires every employer to ensure that medical personnel are readily available for advice and consultation. When an infirmary, clinic, or hospital is not within close proximity to the workplace, an individual (or individuals) who is adequately trained to administer first aid must be present during every work shift. Employers are responsible for making decisions about the details of emergency medical care in their workplaces, depending on the size, the kinds of hazards present, the history of accidents, and the costs of various options (29 CFR 1910.151).
