· Rules. Missouri is not a "state plan" state; that is, it does not have a federally approved occupational safety and health program. Therefore, the federal OSH Act and regulations govern private sector employers. Missouri has no worker right-to-know law for public sector (state and local government offices and operations) workplaces.
The Hazard Communication Standard, popularly known as "worker right to know," is a part of the federal OSH Act. Worker right to know is intended to inform employees about the health hazards of the toxic chemicals and other hazardous substances present in their workplaces. For a detailed discussion of the standard, see the national section HAZARD COMMUNICATION STANDARD.
· Administration and enforcement. OSHA administers and enforces the federal rules under the OSH Act for private sector workplaces in Missouri.
