Oklahoma does not have a federally approved occupational safety and health regulatory program. Consequently, federal occupational safety and health standards govern private sector workplaces in the state.
The state has adopted by reference the federal confined spaces standard for public sector (state and local government) workplaces in general industry and construction (Oklahoma Administrative Code 380:40-1-22).
The U.S. Department of Labor/Occupational Safety and Health Administration (OSHA) administers and enforces federal workplace safety and health requirements in private sector workplaces. The Oklahoma Department of Labor/Public Employee Occupational Safety and Health Unit administers safety and health rules for public sector workplaces.
