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 Arizona Health and Safety Code, which is virtually identical to the federal Occupational 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. According to OSHA, for areas where accidents resulting in suffocation, severe bleeding, or other life-threatening or permanently disabling injury or illness can be expected, "close proximity" means a 3- to 4-minute response time (from time of injury to time of administering medical treatment or first aid). In other circumstances, such as where a life-threatening or permanently disabling injury is an unlikely outcome of an accident, a longer response time such as 15 minutes is acceptable.
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.
State follows federal requirements. Arizona has adopted the federal safety and health standards by reference. for an explanation of federal requirements and a description of an effective workplace medical program.
