5 GHS Overview “ Globally Harmonized System Of Classification And Labeling Of Chemicals” –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 GHS Overview Elements –Harmonized criteria for classifying substances and mixtures according to their health, environmental and physical hazards –Harmonized hazard communication elements, including requirements for labeling and safety data sheets. –Guide to the GHS (OSHA)Guide to the GHS (OSHA) GHS “Purple Book”

7 GHS Overview Justification –Label requirements differ, requiring multiple labels for the same product –Hazard definitions are not consistent Toxicity, Flammability –Globally over 100 diverse hazard communication regulations for their products globally Regulatory compliance is complex and costly Barrier to international trade in chemicals

Flammability Example OSHA letter of interpretation, July 14, 2010 –Re: The definitions of combustible and flammable liquids under 29 CFR 1926 and 29 CFR –Question: Why are the definitions for combustible liquids and flammable liquids different under OSHA's construction and general industry standards? –Answer: The definitions in the two standards are different because the definitions were adopted from different sources. OSHA is currently addressing these definitions in the Hazard Communication rulemaking. [GHS} – p_table=INTERPRETATIONS&p_id=27488http:// p_table=INTERPRETATIONS&p_id=

13 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 –All systems will have to be changed –Involvement of all stakeholders should be ensured –Comprehensibility must be addressed

14 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

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

16 GHS Hazard Classification Health Hazards (10) –Acute Toxicity –Skin Corrosion/Irritation –Serous 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

17 GHS Hazard Classification Hazardous to the Aquatic Environment –Acute aquatic toxicity –Chronic aquatic toxicity Bioaccumulation potential Rapid degradability

Labels –Symbols (hazard pictograms) with red border Examples: 18 GHS Hazard Communication

19 GHS Hazard Communication Labels (cont.) –Nine symbols Includes “Environment”

Labels (cont.) –Signal Words “Danger” or “Warning” –Hazard Statements Example: “Toxic if swallowed” –Other Precautions, identification, supplier, supplemental 20 GHS Hazard Communication

Labels (cont.) –GHS Label Elements for Flammable Liquids 21 GHS Hazard Communication

22 GHS label example

23 GHS Hazard Communication GHS Safety Data Sheet (SDS) –16 headings –Similar to ISO, EU, and ANSI MSDS/SDS requirements

24 OSHA MSDS format (old) OSHA-174 (1989), 8 sections (non- mandatory) 1.Manufacturer information 2.Hazard Ingredients/Identity Information 3.Physical/chemical properties 4.Fire and Explosion Hazard Data 5.Reactivity Data 6.Health Hazard Data 7.Precautions for Safe Handling and Use 8.Control Measures

25 ANSI MSDS format ANSI Z Product and Company Identification 2.Hazard Identification 3.Composition / Information On Ingredients 4.First Aid Measures 5.Fire Fighting Measures 6.Accidental Release Measures 7.Handling and Storage 8.Exposure Control / Personal Protection 9.Physical and Chemical Properties 10.Stability and Reactivity 11.Toxicological Information 12.Ecological Information 13.Disposal Considerations 14.Transport Information 15.Regulatory Information 16.Other Information

26 OSHA and the GHS Rulemaking Steps –Advance Notice of Proposed Rulemaking, ANPR Sept. 12, 2006 –Notice of Proposed RulemakingNotice of Proposed Rulemaking Sept. 30, 2009 Public Comment Period ended Dec. 29, 2009 Public Hearings –Washington, Pittsburgh and Los Angeles –March and April, 2010 Post-hearing Comment Period ended June 1, 2010 –Final Standard Probably by late 2011, according to OSHA staff –Phase-in Period for Compliance 2-3 years (as proposed)

27 Proposed 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 hazard –Safety Data Sheets with 16 sections May include guidance for transportation information and environmental hazards –Side-by-side comparison (OSHA)Side-by-side comparison (OSHA)

28 Proposed OSHA rule Major changes to the Hazard Communication Standards (cont.) –Other OSHA standards are changed where applicable New wording on warning signs for asbestos and other health hazards Changes to standards for HAZWOPER, Combustible and Flammable Liquids, Welding Cutting and Brazing, etc.

29 Proposed OSHA rule Effective dates –Two years after final rule Employee training on new labels and safety data sheets –Three years after final rule Chemical manufacturers, importers, distributors, and employers in compliance with all modified provisions

30 Proposed OSHA rule Costs and benefits –$97 million annual cost training, SDSs & labels, management –$851 million annual benefit reduced injuries/illnesses/fatalities, improved productivity and cost reduction –$754 million net annual benefit

31 OSHA interpretation GHS labels comply with current OSHA requirements –Standard Interpretation 10/06/ Using the Globally Harmonized System (GHS) to Comply with OSHA's Hazard Communication Standard – show_document?p_table=INTERPRETATI ONS&p_id=27218http:// show_document?p_table=INTERPRETATI ONS&p_id=27218

32 Comments on the proposed rule OSHA specifically solicited comments about: –Costs and benefits –Effect on “small entities” –GHS classification system –Combustible dusts and simple asphyxiants –Color labels vs. B&W –PELs on data sheets –Etc. Public Hearings ended April 13, 2010 Record closed June 1, 2010 (877 items)

Comments on the proposed rule Maureen Ruskin, director of OSHA's Office of Chemical Hazards, at GHS Round Table, 5/24/2010, AIHCE, Denver, Co –Vast majority of comments support OSHA –OSHA should adopt EU reporting limits for chronic hazards –Create “hazards not otherwise classified” category –Support and criticism of proposal to drop TLVs –Updating labels within 30 days may not be feasible –OSHA may have underestimated cost of red border –Mixed support for adoption of GHS hazard statements –Disagreement about implementation dates –OSHA should provide more information for training 33

Comments on the proposed rule OSHA’s update (cont.) –Some believe OSHA will create confusion with changes to flammable/combustible liquid classification, yet others agreed with OSHA –OSHA should review safety standards to avoid conflicts –Concerns over carcinogen notation changes in the health standards –Concerns about conflict or confusion regarding EPA/DOT/NFPA –OSHA underestimated costs –Very little support for OSHA’s proposed alternatives –How will OSHA respond after UN updates GHS? 34

35 ASSE’s comment “ASSE applauds OSHA for its leadership in undertaking this rulemaking and urges that every possible step be taken to achieve a final rule as soon as practicable.” However, ASSE has some concerns: –OSHA should include “control banding” –OSHA underestimated the impact on small business –Some hazard classifications should be modified –OSHA should require red borders on labels –Labels should have more required information –TLV and REL exposure limits should be listed on data sheets –The new standard should have a shorter deadline for training –There may be a shortage of SH&E professional on staff –Etc.

36 AIHA’s comment “AIHA supports the proposed revision of the HCS and believes it will result in better hazard recognition and safer use of chemicals in the workplace.” AIHA’s generally supports OSHA: –Proposed hazard classifications are OK –OSHA should require red borders on labels –TLVs, WEELs and other exposure limits should be listed on data sheets –OSHA should include a hazard category for combustible dust –Training should not be delayed AIHA also submitted a post-hearing comment, April 29, 2010 to answer OSHA questionsAIHA also submitted a post-hearing comment, April 29, 2010

OSHA’s Schedule Record closed June 1 Tasks: –Analyze information in the record –Prepare the final rule and update the analyses of the record –Submit rule for administrative review –OSHA, DOL, OMB This is high priority for OSHA –Expect final standard about 1 ½ years (?) 37

Recent GHS activity United Nations Subcommittee of Experts on the Globally Harmonized System of Classification and Labelling of Chemicals (UNSCEGHS), Dec. 7-9, 2010, in Geneva OSHA hosted an open informal public meeting of the U.S. Interagency GHS Coordinating Group, Nov. 20, –To provide interested parties with an update on GHS issues in preparation for the UN meeting – p_table=FEDERAL_REGISTER&p_id=21809http:// p_table=FEDERAL_REGISTER&p_id=

OSHA’s Schedule Dr. David Michaels, Assistant Secretary of Labor for OSHA –June 16, 2010 at the Baltimore ASSE conference: the Global Harmonized System standard –a “non-controversial rule” – has received good comments and is moving along on target Source: Occupational Health and Safety online magazine 39

43 Impact on Safety and IH Professionals Become familiar with the new system –May want to wait until the OSHA rule is “final” Collect new SDSs 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 Train employees about new labels and SDS

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 44
