OSHA Amends Hazard Communication Standard to Align with UN’s Globally Harmonized System

In the May 20, 2024 issue of the Federal Register, the Occupational Safety and Health Administration (OSHA) issued a final rule amending the Hazard Communication Standard, 29 CFR § 1910.1200, to conform to the United Nation’s Globally Harmonized System of Classification and Labelling of Chemicals.
The final rule becomes effective July 19, 2024.
This amendment will provide better alignment with other U.S. agencies and international trading partners, while enhancing the effectiveness of the standard. The modifications to the standard include revised criteria for physical hazards, revised provisions for updating labels, new labeling provisions for small containers, new provisions related to trade secrets, technical amendments related to the contents of safety data sheets, and related revisions to definitions of terms used in the standard.
