The final revised OSHA Hazard Communication Standard (HCS) was published in the Federal Register on March 26, 2012.

This revision will align the HCS with the Globally Harmonized System of Classification and Labeling of Chemicals (GHS). The major changes caused by this revision include:

  • Hazard classification: Provides specific criteria for classification of health and physical hazards, as well as classification of mixtures.
  • Labels: Chemical manufacturers and importers will be required to provide a label that includes a harmonized signal word, pictogram, and hazard statement for each hazard class and category. Precautionary statements must also be provided.
  • Safety Data Sheets: Will now have a specified 16-section format.
  • Information and training: Employers are required to train workers by December 1, 2013 on the new labels elements and safety data sheets format to facilitate recognition and understanding.
