2. Tulane University - Office of Environmental Health & Safety (OEHS) Objectives To become familiar with: The 2012 revisions to the OSHA Hazard Communication Standard The Globally Harmonized System of classification & labeling of chemicals (GHS) New requirements for labeling of chemicals New format for safety data sheets

3. Tulane University - Office of Environmental Health & Safety (OEHS) OSHA Hazard Communication Standard Revised March 26, 2012 (29 CFR 1910.1200) Now includes certain aspects of globally harmonized system of classification and labeling of chemicals (GHS) Purpose: To understand chemical hazards in the workplace and how to protect yourself

4. Tulane University - Office of Environmental Health & Safety (OEHS) OSHA Hazard Communication Standard Major changes include: “Right to Know” changes to “Right to Understand” Several definitions revised, changed, or deleted “Hazard determination” now “hazard classification” Significant changes to labels Specified format for Safety Data Sheets (formerly Material Safety Date Sheets)

5. Tulane University - Office of Environmental Health & Safety (OEHS) What is GHS? Globally Harmonized System: A worldwide initiative to promote standard criteria for classifying chemicals Criteria-based definitions of physical, health, and environmental hazards OSHA has not adopted environmental aspects of GHS because it does not have jurisdiction over environmental matters

23. Chemical Classifications – Numerical Rankings Under the GHS classifications, chemicals are also placed into numerical hazard rankings GHS numerical rankings are OPPOSITE from the numbering systems that have traditionally been used in the U.S. (such as the NFPA or HMIS ratings) in which 4 is the most hazardous and 0 or 1 the least hazardous In the GHS system, Category 1 would be the most hazardous
