Hazard Communication 2012

1. Hazard Communication 2012 Incorporation of the Globally Harmonized System of Classification and Labeling of Chemicals (GHS)

2. The Hazard Communication Standard • OSHA Standard 29 CFR 1910.1200 • Addresses how chemical hazards are communicated to employees working with or around chemicals • Being aware of the hazards enhances employees’ ability to work safely around those chemicals • First written in 1983; Major revision in 2012 to bring it in line with international standards

3. What is the GHS*? *Globally Harmonized System of Classification and Labeling of Chemicals • A common and coherent approach to defining and classifying hazards, and communicating information on labels and safety data sheets. • Target audiences include workers, consumers, transport workers, and emergency responders. • It is an international standard adopted by the United Nations in 2003. • How is this different from the original Hazard Communication Standard?

4. Old Haz Com vs. Haz Com 2012 • “Right to Know” • Container labels have identity, hazard warnings, and responsible party • Material Safety Data Sheets (MSDSs) look very different depending on vendor • No standardized method of hazard classification • “Right to Understand” – improves ability of employees to quickly find and understand critical chemical safety info • Container labeling requirements are much more specific • Safety Data Sheets (SDSs) all formatted the same way – increased consistency makes it easier to find necessary info • Chemical and mixture hazards classified according to decision trees

5. Additional Benefits of Haz Com 2012 • No country has the ability to identify and specifically regulate every hazardous chemical product (650,000 in the US!) • Countries with different chemical classification systems require different hazard definitions, labels, and SDSs. This impacts protection and trade. • Harmonization of classification and labeling: • Enhances protection of humans and environment. • Facilitates international trade in chemicals. • Reduces need for testing and evaluation. • Assists countries and international organizations to ensure the sound management of chemicals.

6. What is in the revised Haz Com Standard? • Purpose • Scope and Application • Definitions • Hazard Classification • Written Hazard Communication Program • Labels and Other Forms of Warning • Safety Data Sheets • Employee Information and Training • Trade Secrets • Effective Dates • Appendices A-F

7. The Scope of Haz Com 2012 • There has been little change to the scope: • Covers all hazardous chemical substances, dilute solutions (i.e., secondary containers), and mixtures. • Pharmaceuticals, food additives, cosmetics and pesticide residues in food are not covered at the point of intentional intake, but are covered where workers may be exposed, and in transport.

8. Haz Com Written Program Includes: • Policies and Procedures • Essential Elements of the Haz Com Standard • Info on container labeling • Storage and availability of SDSs • Chemical inventory including locations • Guidelines for Employee Training • Information about the specific chemical hazards found in the workplace

9. Training Requirements • Training on specific chemicals to which you may be exposed • Methods used to monitor the presence of hazardous chemicals • Warning signals to indicate a leak or spill • Physical and health hazards of chemicals in your work area • Safe work practices and PPE used to prevent exposure • How to read info on chemical labels and SDSs • Where SDSs and written plan may be accessed

10. Where are our chemical hazards found? • Primarily in laboratories • But don’t forget cleaners, pesticides, herbicides, printer toner, etc.

11. How to detect the presence or release of a hazardous chemical Sight and Smell

12. How to Protect Yourself from Chemical Hazards • Use appropriate work practices • Know the relevant emergency procedures • Use appropriate personal protective equipment • Check SDS or ask your supervisor/safety specialist for advice on what is appropriate

13. Where to Find OurHaz Com Program and SDSs Employees can access our written program at any time on the Safety SharePoint site in the “Safety Plans and Other Resources” folder, and it is available as a hard copy or via e-mail upon request SDSs are generally found in binders in the labs where the chemicals are used. However, at the CRL SDSs are kept on a separate MSDS SharePoint site.

14. Three Major Components of Haz Com • Hazard Classification – assigning a chemical or mixture to a hazard or danger category based on its health, physical, or environmental hazards • Container Labels • Safety Data Sheets

15. Hazard Classification • Physical Hazards – Properties of a gas, liquid, or solid that could adversely affect you or the workplace in a physical way (e.g., fire or explosion) • 16 classes • Health Hazards – Properties of a substance or mixture that can cause illness or injury to the skin, eyes, lungs or other organs or parts of the body (e.g., carcinogen) • 10 classes • Environmental Hazards(non-mandatory) – chemicals that are harmful to the aquatic environment and organisms that live in that environment • 2 classes

16. Physical Hazard Classes • Explosives • Flammable Gases • Flammable Aerosols • Flammable Liquids • Flammable Solids • Oxidizing Gases • Oxidizing Liquids • Oxidizing Solids • Self-Reactive Substances • Pyrophoric Liquids • Pyrophoric Solids • Self-Heating Substances • Substances Which in Contact with Water Emit Flammable Gases • Organic Peroxides • Substances Corrosive to Metal • Gases Under Pressure

17. Health Hazard Classes • Acute Toxicity • Skin Corrosion/Irritation • Respiratory or Skin Sensitization • Germ Cell Mutagenicity • Carcinogenicity • Reproductive Toxicity • Target Organ Systemic Toxicity: Single Exposure & Repeated Exposure • Aspiration Toxicity • Serious Eye Damage/ Eye Irritation Environmental Hazard Classes • Acute Aquatic Toxicity • Chronic Aquatic Toxicity

18. Hazards Not Otherwise Classified • Simple Asphyxiants • Phyrophoric Gas • Combustible Dust • These are hazard classes that OSHA wants to address but that are not found in GHS.

19. Approach to Labeling • Appendix C of the Haz Com Standard uses a cookbook approach to labeling • Once classification of hazards is completed, Appendix C is used to determine how to convey required information • Can combine hazard statements for readability

20. Container Label Requirements Example: • Signal words: used to indicate the relative level of severity of a hazard and alert the reader to a potential hazard: "Danger" for more severe hazards or "Warning" for less severe hazards. • Hazard Statement: a statement assigned to a hazard class and category that describes the nature of the hazard(s) of a chemical, including, where appropriate, the degree of hazard. (Example: Highly flammable liquid and vapor.) • Precautionary Statement: a phrase that describes recommended measures to be taken to minimize or prevent adverse effects resulting from exposure to a hazardous chemical. May also include proper storage or handling and first aid instructions. • Supplier Information: name, address, phone Required Elements: • Product Identifier: matches that on SDS • Pictograms: a black symbol on a white background within a red diamond.

21. Pictograms and Hazards

22. Hazard Statements • Standard phrases describing the nature of the hazard for each level of hazard within each hazard class • For products that pose more than one risk, a hazard statement will be listed on the label for each GHS hazard • 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 **Note that numbering is the reverse of NFPA and HMIS** – in GHS 1 is most hazardous, 4 is least hazardous

23. Precautionary Statements • These are standard explanations to minimize or prevent adverse effects • 4 types for each hazard class: • Prevention (e.g., Wear protective gloves) • Response (e.g., If on skin, wash with plenty of water) • Storage (e.g., Store in well ventilated place) • Disposal (e.g., Dispose in accordance with local regulations)

24. Workplace Labeling • Same approach as in previous Haz Com Std • Secondary containers must have the name (i.e., Product Identifier) and words, pictures, symbols, or a combination, which provide information regarding the hazards of the chemicals. • Information may need to be updated to be consistent with new classifications • NFPA/HMIS Labeling Systems may still be used!* *According to OSHA/SCHC webinar held Aug 13, 2012 https://goto.webcasts.com/viewer/event.jsp?ei=1006847

25. Allowed Labeling of Secondary Containers • NFPA system (0 = non-hazardous, 4 = highest hazard): • health hazards (blue) • flammability hazards (red) • reactivity hazards (yellow) • special hazards (white) • HMIS system (0 = non-hazardous, 4 = highest hazard): • health hazards • flammability hazards • reactivity hazards • PPE that should be worn • GHS labeling (Category 1 = highest hazard, Category 4 = lowest hazard)

26. Safety Data Sheets (SDS) • Provide comprehensive information about individual chemicals and advice on safety precautions • These replace the MSDSs that were part of the original Haz Com Standard • The consistent format of all SDSs makes it easier to quickly find information about a chemical • We have a SDS or MSDS for every chemical in the building • We will transition from MSDSs to SDSs by 2015, so if you receive SDSs for chemicals you order, please keep them or forward them to me.
