Hazard communication standards, or “worker right-to-know” laws, regulate how information about workplace chemical hazards is communicated to employees. As with most workplace health and safety standards, worker right-to-know laws have developed in large part according to standards adopted under the federal Occupational Safety and Health Act (OSH Act).
Because Maine does not have its own approved occupational safety and health plan, the federal OSH Act and its right-to-know standards are the governing law of the state in all private sector workplaces. The state has adopted the federal safety and health, including worker right-to-know, rules by reference for public sector (state and local government offices and operations) workplaces (ME Rev. Stat. Tit. 26 Ch. 6 Sec. 561et seq.). There is more information about public sector rules. There are detailed discussions of the federal regulations.
