The federal Occupational Safety and Health Act (OSH Act) is “preemptive”; that is, it overrides state work safety and health laws and regulations for the private sector. If an individual state wishes to enact its own work safety laws for private sector employees, it must have federal approval, and its state plan must be at least as stringent as the federal act.
Idaho does not have an approved occupational safety and health regulatory program; therefore, in the private sector workplace, the OSH Act prevails and governs health and safety.
Public (state government offices, commissions, boards) sector workplaces are regulated under state workplace safety and health laws (ID Code Sec. 67-2311 et seq.; ID Admin. Code 17.10.01), administered by the Idaho Division of Building Safety.
