The federal Occupational Safety and Health Act (OSH Act) is “preemptive;” that is, it overrides state laws and regulations in the areas it covers. Since this amounts to virtually all areas of workplace health and safety in the private sector, the OSH Act supplants most state work safety requirements. Under the OSH Act, individual states may devise and administer their own laws and regulations, but only with federal approval, and only if the applicable state requirements are as stringent as the corresponding federal standards.
Mississippi has not adopted any workplace safety and health rules of its own; therefore, workplace health and safety in the private sector (businesses and nonprofit organizations) is governed by the federal OSH Act standards, administered by the Occupational Safety and Health Administration (OSHA). There are no workplace safety and health rules for public sector (state and local government) workplaces. There is additional information and a discussion of the federal standards.
