Global Harmonization

The new HCS 2012 is now aligned with the United Nations Globally Harmonized System of Classification and Labeling of Chemicals (GHS) that provides many benefits, including:

• Providing a common and coherent approach to classifying chemicals and communicating hazard information on labels and safety data sheets;
• Improving the quality and consistency of hazard information in the workplace;
• Helping reduce trade barriers;
• Productivity improvements for American businesses that regularly handle, store, and use classified hazardous chemicals;
• Providing cost savings for American businesses that periodically update safety data sheets and labels for classified chemicals.

Historical note: The old HCS 1994 gave workers the right to know, but the new HCS 2012 gives workers the right to understand: this is a very important change in OSHA’s approach.
