Montana does not have a federally approved occupational safety and health regulatory program for the state; therefore, private sector workplaces must comply with federal occupational safety and health standards.
The state has adopted the federal confined space rules by reference (Admin. Rules of MT 24.30.102) for public sector (local and state government offices and operations) employers in general industry workplaces.
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 in the state. The Montana Department of Labor and Industry (DLI)/Safety and Health Bureau administers workplace safety and health rules in public sector workplaces.
