The Hazard Communication Standard (HCS) is now aligned with the Globally Harmonized System of Classification and Labeling of Chemicals (GHS). This update to the Hazard Communication Standard (HCS) will provide a common and coherent approach to classifying chemicals and communicating hazard information on labels and safety data sheets. Once implemented, the revised standard will improve the quality and consistency of hazard information in the workplace, making it safer for workers by providing easily understandable information on appropriate handling and safe use of hazardous chemicals. 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.
During the transition period employers may comply with either the HazCom 1994, the Haz Com 2012, or both. This page provides information on the 1994 Hazard Communication standard (HazCom 1994), as well as general information on hazard communication. For information on HazCom 2012, please click on the "Hazard Communication" logo at the top of the page, or on Hazard communication 2012 in the contents box to the right. The effective dates for the HazCom 2012 can found at: http://www.osha.gov/dsg/hazcom/effectivedates.html
