These materials provide general requirements for the Hazard Communication Standard (see 29 CFR 1910.1200(g) and Appendix D of 29 CFR 1910.1200). It does not alter or determine compliance responsibilities in the standard or the Occupational Safety and Health Act of 1970. Since interpretations and enforcement policy may change over time, the reader should consult current OSHA interpretations and decisions by the Occupational Safety and Health Review Commission and the courts for additional guidance on OSHA compliance requirements. Please note that states with OSHA-approved state plans may have additional requirements for the Hazard Communication Standard, outside of these outlined. For more information on those standards, please visit: 

Other information related to the revised Hazard Communication Standard can be found on OSHA’s Hazard Communication Safety and Health Topics page, located at:
