EXPERT ANALYSIS: U.S. OSHA Amends HazCom To Align With GHS Revision 7

On 20 May 2024, the U.S. Occupational Health and Safety Administration (OSHA) amended the Hazard Communication Standard (HazCom) (29 CFR 1910.1200) to align with the Globally Harmonized System of Classification and Labeling, 7th Revised Edition (GHS Rev.7). 

OSHA amended the HazCom standard to better align requirements with U.S. trading partners and to correct or clarify some points in the existing regulation. The safety data sheets (SDS) and label requirements in the U.S. were aligned with the 3rd Revised Edition of the GHS. This regulation aligns with the GHS Rev. 7, adds some elements from GHS Rev. 8, but still retains some U.S.-specific requirements not included in the GHS.
