2. GLOBALLY HARMONIZED SYSTEM for HAZARD COMMUNICATION Steven Weberman, Industrial Hygienist ADOSH IH Consultant, 602-542-1655 weberman.steve@dol.gov

3. Outline GHS overview Changes to the Hazard Communication Standard Effective Dates

4. Introduction 1983: OSHA’s Mandates the Hazard Communication Standard - 1910.1200. Written Program Inventory List Labeling MSDS Employee Training & Information 2015, Major Overhaul to the Standard !

5. GHS Overview “Globally Harmonized System of the Classification & Labeling of Chemicals and Safety Data Sheets” United Nations guidance for a uniform (harmonized) hazard communication system Initiated at the 1992 United Nations Conference on Environment and Development (UNCED) Based on ”major” existing systems USA and Canadian systems for the workplace, workplace, consumers and pesticides European Union directives for classification and labeling of substances and preparations United Nations Recommendations on the Transport of Dangerous Goods.

6. OSHA rule Major changes to the Hazard Communication Standards Changed “hazard determination” to “hazard classification” Changed “MSDS” to “SDS” Changed definitions to comply with GHS Labels for shipped containers must have GHS information Workplace labels may be GHS labels, or other labels that identify the material and hazards that are as effective as the GHSlabels. Safety Data Sheets with 16 sections Will include guidance for transportation information and environmental hazards.

7. OSHA rule Other OSHA standards will be affected where applicable (incorporated by reference) New wording on warning signs for asbestos and other health hazards. Affected standards include: HAZWOPER, Combustible and Flammable Liquids, Welding, Cutting and Brazing, Chemical Hygiene Plan, Permit-Required Confined Space Entry, etc.

8. GHS Overview Elements Harmonized criteria forclassifying substances and mixtures according to their health, environmental and physical hazards Harmonized hazard communication elements, including requirements for labeling and safety data sheets. http://www.unece.org/trans/danger/publi/ghs/ghs_rev04/04files_e.html GHS “Purple Book”

9. GHS Overview Justification Label requirements differ, requiring multiple labels for the same product Hazard definitions are not consistent Toxicity, Flammability Over 100 diverse hazard communication regulations for manufacturer’s products globally. Regulatory compliance is complex and costly Barrier to international trade in chemicals

12. GHS Overview Key Guiding Principles of the Harmonization Process Protection will not be reduced Will be based on intrinsic properties (hazards) of chemicals All types of chemicals will be covered

13. I. GHS - Hazard Classification Defined criteria are used to assign a hazard classification Physical Hazards 16 categories Health Hazards 10 categories Environmental Hazards Mixtures GHS classification guidance for when chemicals are mixed for in house use or when exported.

14. GHS - Hazard Classification Physical Hazards (16) Explosives Flammable Gases Flammable Aerosols Oxidizing Gases Gases Under Pressure Flammable Liquids Flammable Solids Self-Reactive Substances Pyrophoric Liquids Pyrophoric Solids Self-Heating Substances Substances which, in contact with water, emit flammable gases Oxidizing Liquids Oxidizing Solids Organic Peroxides Corrosive to Metals

15. GHS - Hazard Classification Health Hazards (10) Acute Toxicity Skin Corrosion/Irritation Serious Eye Damage/Eye Irritation Respiratory or Skin Sensitization Germ Cell Mutagenicity Carcinogenicity Reproductive Toxicology Target Organ Systemic Toxicity – Single Exposure Target Organ Systemic Toxicity – Repeated Exposure Aspiration Toxicity

16. GHS - Hazard Classification Hazardous to the Aquatic Environment - Acute aquatic toxicity Chronic aquatic toxicity Bioaccumulation potential Rapid degradability

17. Labels Symbols (hazard pictograms) with red border Examples: II. GHS - LABELS

18. GHS - LABELS Nine Symbols Includes “Environment”

19. Signal Words “Danger” or “Warning” Hazard Statements Example: “Toxic if swallowed” Other Precautions, identification, supplier, supplemental GHS - LABELS

20. GHS Flammability Rating 1 = EXTREME ( FL. Class IA) “DANGER” 2 = MODERATE ( FL. Class IB) “DANGER” 3 = SLIGHT ( FL. Class IC / Comb. Class II) “WARNING” 4 = COMBUSTIBLE ( Comb. Class IIIA) “WARNING” (No Rating for Combustible Class IIIB or lower)

21. GHS - Label Elements for Flammable Liquids GHS - LABELS

22. NFPA - Flammability • 4 = Will rapidly or completely vaporize at normal pressure and temperature, or is readily dispersed in air and will burn readily. • 3= Liquids and solids that can be ignited under almost all ambient conditions. • 2= Must be moderately heated or exposed to relatively high temperature before ignition can occur. • 1= Must be preheated before ignition can occur. • 0= Materials that will not burn.

23. The next slide shows the difference, very slight difference, in regards to the temperature change from the NFPA Classes to the GHS flammability ratings. • Example: where the Class IA and IB = 73.0 degrees F and under GHS the rating of 1 = 73.4 degrees F • The other temperature’s are about the same difference = 0.3 or 0.4 degrees F

24. Flammability example

25. GHS - Label example

27. III. GHS – Safety Data Sheets 16 headings Similar to ISO, EU, and ANSI MSDS/SDS requirements

28. OSHA MSDS format (old) OSHA-174 (1989), 8 sections (non-mandatory) Manufacturer information Hazard Ingredients/Identity Information Physical/chemical properties Fire and Explosion Hazard Data Reactivity Data Health Hazard Data Precautions for Safe Handling and Use Control Measures 28

29. ANSI MSDS format (GHS) ANSI Z400.1-2004 Product and Company Identification Hazard Identification Composition / Information On Ingredients First Aid Measures Fire Fighting Measures Accidental Release Measures Handling and Storage Exposure Control / Personal Protection Physical and Chemical Properties Stability and Reactivity Toxicological Information Ecological Information Disposal Considerations Transport Information Regulatory Information Other Information 29

30. EFFECTIVE DATES - OSHA rule Federal & State Effective Completion Dates: December 1, 2013: Employers must inform employees on the new label elements and SDS format. June 1, 2015* Chemical manufacturers, importers, distributors and employers must comply with all modified provisions of this final rule. Distributors may ship products labeled by manufacturers under the old system until December 1, 2015. * This date coincides with the European Union implementation date for classification of mixtures. June 1, 2016: Employer’s Must update alternative workplace labeling and hazard communication program as necessary, and provide additional employee training for newly identified physical or health hazards. Transition Period Must Comply with either 29 CFR 1910.1200 (the final standard), or the current standard, or both for all chemical manufacturers, importers, distributors and employers.

31. The Impact on Safety and IH Professionals Become familiar with the new system. Collect new SDS’s as provided by suppliers and incorporate them into the existing MSDS system (or use a commercial service) Get new GHS labels for “shipped containers” Employers can use other systems for workplace labeling that are effective as the GHS labels. Inform employees about new labels and SDS by December 1, 2013.

32. Impact on Chemical Manufacturers and Distributors Prepare and use new GHS compatible labels Prepare and distribute new GHS compatible Safety Data Sheets Commercial “authoring” firms are ready and willing to help
