Hazard communication standards, or “right-to-know” laws, regulate how information about workplace chemical hazards is communicated to employees. As with most workplace health and safety standards, right-to-know laws have developed in large part according to standards adopted under the federal Occupational Safety and Health Act (OSH Act). The law allows individual states to devise and administer their own work safety laws and regulations, but only if the state program has federal approval. To qualify, a state plan must be at least as stringent as federal standards.
Because Oklahoma does not have its own approved occupational safety and health plan, the OSH Act and its right-to-know standards are the governing law of the state in all private sector employment. A comprehensive discussion of the federal regulations is available.
Oklahoma no longer has its own hazard communication standard for public sector employers. Public sector employers in Oklahoma must follow the state hazard communication, or worker right-to-know law, which has adopted the federal hazard communication standard by reference.
