2 Overview  What is the Globally Harmonized System?  What changed in OSHA’s new Chemical Hazard Communication standard?  SDS  Labels  What about DOSH/Resources?

3 What is the Globally Harmonized System (GHS)?

4 What is the GHS?  Harmonized criteria for the classification of substances and mixtures according to their health, environmental and physical hazards.  Harmonized hazard communication system including requirements for labelling and safety data sheets.  Target Audience - workers, employers, consumers, transport workers, emergency responders


6 Agencies Involved with the GHS FederalWashington State USEPADOE & WSDA DOTWSDOT OSHAL&I / DOSH CPSC

7 Dark green: Countries/regions that have already implemented GHS. Light green: Countries/regions where GHS is voluntary. Yellow: Countries/regions that are in the process of implementing GHS. Blue: Countries/regions where GHS is not implemented or not available.

8 OSHA’s new GHS-based Hazard Communication Standard Adopted March 26, 2012 “HazCom 2012”

9 Hazcom 2012 Standard  Published March 26, 2012  Conform to the Globally Harmonized System for the Classification and Labelling of Chemicals (GHS) Rev 3  Changes to –Classification –Label Content –Safety Data Sheet Content (mandatory 16 section SDS, % required)  No Changes to –Scope and Exemptions –Written Hazcom Program –Labeling requirement –MSDS Distribution and Availability in the Workplace –Employee Information and Training (other than training on new labels and MSDS within 2 years) –Trade Secrets (except to include percentage)

10 Labeling exemptions  Pesticides  Toxic Substances Control Act (TSCA) regulated chemicals  Food, food additives, color additives, drugs, cosmetics, medical/veterinary devices, alcoholic beverages  Consumer products when labeled in accordance with the Consumer Product Safety Commission (CPSC)  Seeds treated with pesticides if labeled under US Department of Agriculture (USDA)

11 Label and SDS Exemptions  Hazardous waste  Hazardous substances at a CERCLA remediation site  Tobacco  Wood and wood products which will not be processed and only present a fire hazard  Articles  Food and alcoholic beverages sold, used or prepared in retail establishments or intended for personal consumption

12 Major Changes  Labels & (M)SDS –No longer performance-based. –Each hazard class and category has specified hazard statement(s), signal word, pictogram(s), and precautionary statement(s) in mandatory Appendix C. Those elements must appear on the label and (M)SDS.

13 What changed in the Haz Com standard?  Hazard determination –Now titled “hazard classification” –Detailed data-based criteria Health hazard criteria in mandatory Appendix A and non-mandatory Appendix F Physical hazard criteria in mandatory Appendix B –Specified; no longer performance-based

14 Classification of chemical hazards (Appendices A & B)  Hazard class: the nature of the physical or health hazards, e.g., flammable solid, carcinogen, oral acute toxicity.  Hazard category: division by degree or type of hazard within each hazard class.





19 Exploding Bomb Symbol Unstable Explosives Explosives (Divisions 1.1-1.4) Self-reactives (Type A and Type B with Flame) Organic Peroxides (Type A and Type B with Flame)

20 Flame Symbol  Flammable Gases  Flammable Aerosols  Flammable Liquids (Categories 1- 3)  Flammable Solids  Self-Reactives (Type B with bomb, Types C-F)  Pyrophoric liquids and solids  Self-heating substances  Substances which in contact with water emit flammable gases  Organic Peroxides (Type B with bomb, Types C-F)

21 Flame over Circle Symbol  Oxidizing Gases  Oxidizing Liquids  Oxidizing Solids

22 Gas Cylinder Symbol  Compressed Gas  Liquefied Gas  Refrigerated Liquefied Gas  Dissolved Gas

23 Corrosion Symbol  Corrosive to Metals (steel or aluminum >6.25 mm/year at 55C)  Skin corrosion/ irritation – Category 1 (A, B and C)  Serious eye damage/ irritation – Category 1

24 Skull and Crossbones Symbol  Acute Toxicity – Categories 1-3 (oral, inhalation or dermal routes)

25 Exclamation Mark Symbol  Acute Toxicity – Category 4 (oral, inhalation or dermal routes)  Skin Irritation/ Corrosion – Category 2  Serious Eye damage/ irritation – Category 2A  Skin Sensitizer  STOST (single exposure) – Category 3 (respiratory tract irritation, narcotic effects)  Hazardous to the Ozone Layer

26 Health Hazard Symbol  Respiratory Sensitizer  Germ Cell Mutagenicity  Carcinogenicity  Toxic to Reproduction  STOST (single exposure) – Categories 1-2  STOST (repeated exposure) – Categories 1-2  Aspiration Hazard

27 Environment Symbol  Acute hazards to the aquatic environment – Category 1 (Categories 2 and 3 no symbol or signal word)  Chronic hazards to the aquatic environment – Categories 1 and 2 (Categories 3 and 4 no symbol or signal word)

28 Multiple Hazards  Use all symbols except (different in different GHS adoptions): –OSHA precedence –If skull and crossbones, no exclamation point for acute toxicity –If corrosive, no exclamation point for eye/skin irritation –If health hazard for respiratory sensitization, no exclamation point for skin sensitization or eye/skin irritation

29 Hazard Statements  Hazard statement for each level of hazard (category) within each hazard class (See Appendix C) –Example: Flammable liquids Category 1: Extremely flammable liquid and vapour Category 2: Highly flammable liquid and vapour Category 3: Flammable liquid and vapour Category 4: Combustible liquid 29

30 Hazard Statement Text  The text of all applicable hazard statements shall appear on the label.  Hazard statements may be combined where appropriate to reduce the information on the label and improve readability, as long as all of the hazards are conveyed as required. 30

31 31 Precautionary Statements "Precautionary statement" means a phrase that describes recommended measures that should be taken to minimize or prevent adverse effects resulting from exposure to a hazardous chemical, or improper storage or handling.

32 OSHA Precautionary Statements  There are 4 types of precautionary statements –Prevention –Response –Storage –Disposal 32

33 OSHA Precautionary Statements  Precautionary statements may be combined or consolidated to save label space and improve readability.  Where a chemical is classified for a number of hazards, and the precautionary statements are similar, the most stringent shall be included on the label  An order of precedence may be imposed  If the chemical manufacturer, importer, or responsible party can demonstrate that a precautionary statement is inappropriate to a specific substance or mixture, the precautionary statement may be omitted from the label. 33

34 Supplementary Hazard Information  Limited to when it provides further detail and does not contradict or cast doubt on the validity of the standardized hazard information  Placement shall not impede identification of information required by the Standard. 34

35 Label Arrangement  Label elements located together on the label, tag or mark  Must not conflict with DOT regulations  Pictograms must have red border.  Red frame must be wide enough to be clearly visible  Blank red diamonds are not permitted  Where a DOT label appears on a shipped container, the same OSHA pictogram shall not appear.  Labels must be in English (other languages also permitted)

36 1.Product identifier4. Hazard statement(s) 2.Signal word5. Precautionary statement(s) 3.Pictogram(s)6. Contact info for responsible party

37 Workplace Labeling Will you continue to use HMIS or NFPA? While the hazard category number does not appear on the label, consider: HAZARD CategoryHazard 1highest 2high 3medium 4low HMIS/NFPA IndexHazard 1slight 2moderate 3serious 4severe

38 What else changed in the Haz Com standard?

39  Safety Data Sheets –16-section format now required, similar to the current ANSI format. –Order of the sections is specified. –Specific required information for each section is in mandatory Appendix D. –Environmental provisions are included to be GHS- compliant; OSHA will not enforce (sections 12-15).

40 SDS  Chemical manufacturers and importers shall obtain or develop a safety data sheet for each hazardous chemical they produce or import.  Employers shall have a safety data sheet in the workplace for each hazardous chemical which they use.  Must be in English (additional languages permitted)  No relevant information for a sub-heading, must be marked to indicate no data  Preparer must assure information accurately reflects the scientific evidence used in making hazard classification  Update within 3 months of significant new information. If not currently produces – before shipped again / introduces into the workplace

41 Manufacture SDS Distribution  Provide with initial shipment and with first shipment after update  Either before or with the shipment On request  Retail and wholesale distributors shall post a sign or inform employers that SDS are available

42 New SDS elements  Standardized pictograms, hazard statements, signal words, and precautionary statements.  Exact percentages of ingredients are required in most cases; some may still give ranges.

61 GHS will also require changes in other standards  Wording of signs and labels required in many substance-specific standards.  Definitions of flammable and combustible materials in multiple standards.  Affects virtually all standards addressing chemical hazards (including PSM, laboratories, spray finishing, dipping, coating, welding, hazardous waste, emergency response, etc.).

62 Stay tuned...  The GHS is updated on a two year cycle.  Recent updates have mostly been text clarifications.  Future updates of the Chemical Haz Com Standard may be necessary –Technical updates for minor terminology changes. –Direct Final Rules for text clarification. –Notice and Comment rulemaking for more substantive or controversial updates.

63 What about Labor and Industries?

64 The new DOSH Haz Com standard  Is expected to be identical to the federal version.  Rulemaking process expected to start 12/18/12, with an effective date of 3/3/13.  There will be outreach, consultation, workshops, and videos to assist employers.  June 1, 2014 – Expected deadline for employers to train employees on new label and SDS formats.
