On March 26, 2012, federal OSHA issued this final rule (Federal Register) to modify its Hazard Communication Standard (HCS) to conform to the United Nations’ Globally Harmonized System of classification and Labeling of Chemicals (GHS). 

The modifications to the standard include revised criteria for classification of chemical hazards; revised labeling provisions that include requirements for use of standardized signal words, pictograms, hazard statements, and precautionary statements; a specified format for safety data sheets; and related revisions to definitions of terms used in the standard, and requirements for employee training on labels and safety data sheets. OSHA is also modifying provisions of other standards, including standards for flammable and combustible liquids, process safety management, and most substance specific health standards, to ensure consistency with the modified HCS requirements. 

The N.C. Commissioner of Labor adopted this final rule verbatim with an effective date of June 11, 2012.
