Health and safety in the workplace are regulated in large part according to standards developed under the Occupational Safety and Health Act (OSH Act), a federal law. The law provides for individual states to devise and administer their own work safety laws and regulations, but only with federal approval and only if the applicable state requirements are at least as stringent as the corresponding federal standards.
Iowa is among the “state-plan” states, which means it has received federal approval for its state plan, governing both private and public workplaces. Iowa's standards are, in most important respects, identical to those established by the federal government. The state law is administered and enforced by the Iowa Workforce Development's Division of Labor (DOL).
