The Hazard Communication Standard is now aligned with the Globally Harmonized System of Classification and Labeling of Chemicals or GHS. This update to the Hazard Communication Standard will provide a common and coherent approach to classifying chemicals and communicating hazard information on labels and safety data sheets. It 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. OSHA's Hazard Communication Standard (HCS) requires the development and dissemination of such information. All employers with hazardous chemicals in their workplaces must have labels and safety data sheets for their exposed workers and train them to handle the chemicals appropriately.
