On March 20, 2012 OSHA released the new Hazard Communication Standard which incorporated aspects of the Globally Harmonized System of Classification and Labeling of Chemicals, otherwise known as GHS. We have made available supplemental booklets containing a side-by-side comparison of the new and old standards. This allows employers to see the changes which were made and to better understand how to train employees on the new requirements. This supplement also contains all appendices as required by OSHA. It is printed in full-color and is 58 pages.
