On April 12, 2021, the Occupational Safety and Health Administration (OSHA) published an official Federal Register notice to extend the comment period of the notice of the proposed amendment in the Hazard Communication Standard (HCS) by one month. As the current HCS is predicated on the third revised edition (Rev 3) of the United Nations (UN) Globally Harmonized System of Classification and Labeling of Chemicals (GHS). The proposed amendments include updating the HCS to be following the seventh revised edition (Rev 7) of GHS.
