The Hazard Communication Standard (HCS) was originally adopted by OSHA in 1994. Since its recent update, it is now aligned with the Globally Harmonized System of Classification and Labeling of Chemicals (GHS) used throughout the world.
Revisions to the HCS are intended to provide a common and coherent approach to classifying chemicals and communicating hazard information on labels and safety data sheets. This update will also help reduce trade barriers and result in productivity improvements for American businesses that regularly handle, store, and use hazardous chemicals while providing cost savings for American businesses that periodically update safety data sheets and labels for chemicals covered under the hazard communication standard.
