What is the Globally Harmonized System? What changed in OSHA’s new Chemical Hazard Communication standard? What about WISHA? 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

5 The current edition is the 4th; revision continue on a 2-year cycle
The current edition is the 4th; revision continue on a 2-year cycle. So far, most have been text clarifications.

6 Agencies Involved with the GHS
Federal Washington State USEPA DOE & WSDA DOT WSDOT OSHA L&I / DOSH CPSC The DOT was actually the first American agency to implement GHS and OSHA’s adoption brings the regulations between those two agencies into greater harmony. The EPA is expected to follow closely on the heels of OSHA’s adoption with revisions to its own standards to bring them into alignment with GHS.

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. To date, over 65 countries have adopted GHS or are in the process of adopting GHS.

8 OSHA’s new GHS-based Hazard Communication Standard
Adopted March 26, 2012 “HazCom 2012” On March 26, 2012, OSHA revised the Hazard Communication Standard to align with the GHS. OSHA calls the new version “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. Appendix A discusses health hazards, and Appendix B discusses physical hazards. Hazard Class: Describes the nature of the physical or health hazards For example, "Gases under Pressure" is an example of a class in the physical hazards group. Hazard Category: Describes the degree of hazard within a class. The specific criteria varies with the type of hazard.

15 Hazard Category (health hazard criteria, Appendix A)
Hazard Class Hazard Category (health hazard criteria, Appendix A) Acute toxicity 1 2 3 4 Skin corrosion/irritation 1A 1B 1C Serious eye damage/irritation 2A 2B Respiratory or skin sensitizers Germ cell mutagenicity Carcinogenicity Reproductive toxicity lactation Specific target organ toxicity - single exposure Specific target organ toxicity - repeated exposure Aspiration These are the hazard classes and categories for health hazards, from Appendix A.

16 Hazard Category (physical hazard criteria, Appendix B) Explosive
Hazard Class Hazard Category (physical hazard criteria, Appendix B) Explosive Unstable Div 1.1 Div 1.2  Div 1.3 Flammable gases 1 2 Flammable aerosols Oxidizing gases Gases under pressure Compressed Liquefied Refrigerated liquefied Dissolved Flammable liquids 3 4 Flammable solids Self-reactive A B C D E F G Pyrophoric liquids Pyrophoric solids Self-heating Emits flammable gas when in contact with water Oxidizing liquids Oxidizing solids Organic peroxides Corrosive to metals These are the hazard classes and categories for physical hazards, from Appendix B.

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 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 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. 31 PDC 408 GHS 2012

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 Product identifier 4. Hazard statement(s)
Example of label showing the required elements. Pictograms are for flammability, acute toxicity, health hazard, and corrosivity. Product identifier 4. Hazard statement(s) Signal word 5. Precautionary statement(s) Pictogram(s) 6. Contact info for responsible party

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

38 What else changed in the Haz Com standard?

39 What else changed in the Haz Com standard?
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). SAFETY DATA SHEETS 12 – Ecological information 13 – Disposal considerations 14 – Transport information 15 – Regulatory information

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. Conditions to avoid and hazardous decomposition products have been in the ANSI standard for several years. Percentage ranges are allowed when: -- there is a trade secret claim. -- when there is batch-to-batch variability in a product. -- for a group of substantially similar mixtures with similar chemical composition.

June 1, 2016 – Employers must update in-house labeling as needed, update written haz com program as needed, & train on any newly-identified hazards.

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.). OSHA is proposing to modify a number of other standards (flammable/combustible liquids, PSM, and substance-specific health standards) to be consistent with the modified HCS requirements Most OSHA substance- specific heath standards require hazard warning signs, usually for regulated areas, and the language required on the signs varies greatly (e.g., Asbestos, 4-Nitrobiphenyl, 13 Carcinogens, Vinyl Chloride, Inorganic Arsenic, Cadmium, Benzene, Coke Oven Emissions, Cotton Dust, DBCP, Acrylonitrile, Formaldehyde, Methylenedianiline, 1,3-Butadiene, Methylene Chloride, and Lead). With the GHS revision, these standards retain the requirements for specific warning language for specific signs; however, OSHA proposed to modify the language to be compatible with GHS and consistent throughout the OSHA standards. Labels for products, mixtures, and raw materials are included in the GHS-modified HCS and are required to be compliant with it. Labels required by the current standards for contaminated clothing, PPE, and waste and debris, which are not addressed in the GHS, are retained, but their language has been changed to be as reflective of GHS terminology as possible

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. Other deadlines will be the same as the federal standard.

65 Current WISHA Chemical Hazard Communication rules will change
WAC Employer Chemical Hazard Communication WAC MSDS and Label Preparation Will become new chapter in March 2013: WAC , Hazard Communication

66 GHS will also require changes in other standards
