Back in 2012, OSHA aligned its Hazard Communication Standard (HazCom or HCS) with Revision 3 of the United Nation’s Globally Harmonized System of Classification and Labeling (GHS), which resulted in the current HazCom 2012 Standard.
Since then, the UN has continued to publish updated versions of the GHS every two years. Its most recent edition — GHS Revision 7 — is of particular significance as OSHA has expressed its intention to update HazCom 2012 to align with this latest version of the system.
