HazCom 2012 Global Harmonization System

1. HazCom 2012Global Harmonization System 29 CFR 1910.1200

2. Background What is OSHA’s Hazard Communication Standard? OSHA’s Hazard Communication standard (29 CFR 1910.1200), promulgated 1994, requires that employees be informed of the hazards of chemical(s) that they work with or are present in their work area.

3. OSHA Hazard Communication Standard (continued) The four elements of the program include: • Ensuring chemicals are labeled • Maintaining departmental/work unit/laboratory chemical inventories • Maintaining Material Safety Data Sheets (MSDS) • Training of personnel by Supervisor on the chemicals that are used or in the workplace

4. OSHA collaborates with United Nation Understanding the need for consistent classifications of hazards chemicals, OSHA decided to better align with the United Nations’ Globally Harmonized System by adopting a common classification and labeling of chemicals. To view details of this report, double click picture.

5. Benefits of Adopting GHS There are several benefits for OSHA in adopting the Globally Harmonized system. In particular, it will provide a common and coherent approach to classifying chemicals and communicating hazard information on labels and safety data sheets. Thus resulting in: • Consistency of information provided • Increase comprehension of hazards • Help address literacy problems • Facilitation of international trade of chemicals

6. OSHA Publishes Revised Standard In March 2012, the revised Hazard Communication Standard became law and included an established timeframe for implementation. The table below outlines the effective dates, requirements and responsible parties.

7. Benefit of HazCom2012 With the University’s mission to “serve North Carolina, the United States, and the World through teaching, research, and public service,” the new requirements under HazCom 2012 will enhance clarity for University employees positioned on campus as well as abroad.

8. HazCom2012 Requirements By December 2013, all University employees are to have received general training regarding “definitions”, “label” and “Safety Data Sheet” for chemicals under new HazCom 2012 standard. Supervisors are still required to provide job specific training to employees on the chemicals used in their area at least once and every time a new chemical is added. The training must cover proper use, handling, and personal protective equipment required for the safe handling of the hazardous chemicals.

9. Definitions HazCom 2012 will use a “specification” approach rather than a “performance-oriented” approach. Hazards will be classified thus providing a specific criteria for classification of health and physical hazards, as well as classification of mixtures. Specifically: • Appendix A defines health and physical hazards • Appendix B includes additional parameters to evaluate health hazard data • Appendix F pertains to Carcinogens

10. Labels HazCom 2012 requires chemical manufacturers and importers to provide a label that includes a harmonized product identifier, pictogram, signal word, and hazard statement for each hazard class and category. Precautionary statements must also be provided.

11. Labels - Pictograms Pictograms are required on labels to alert users of the chemical hazards to which they may be exposed. Each pictogram consists of a symbol on a white background framed within a red border and represents a distinct hazard(s), such as health, physical, and environmental . The pictogram on the label is determined by the chemical hazard classification. There are nine pictograms with only the environmental pictogram being optional.

12. Labels – Distinct Hazards As previously stated, “Distinct hazards” are chemicals in which there is scientific evidence that a health, physical, and/or environmental hazards may occur. • Health Hazard - acute or chronic health affects may occur if exposed. • Physical Hazard - a combustible liquid, a compressed gas, explosive, flammable, an organic peroxide, an oxidizer, pyrophoric, unstable (reactive) or water-reactive • Environmental Hazard – pose risk or danger to the environment

13. Labels – Pictograms (Health) • Acute Toxicity (fatal and toxic) • Fatal in contact with skin • Fatal if inhaled • Fatal if swallowed • Toxic if swallowed • Toxic in contact with skin Examples: Carbon Monoxide, Ammonia, Acrylonitrile, Arsenic Skull and Cross Bones will appear on the most severely toxic chemicals. Depending on the toxicity of the chemical, the skull and crossbones indicates that the chemical may be toxic or fatal. Specifically it can mean:

14. Labels – Pictograms (Health) • May be corrosive to metals • Causes severe skin burns • Causes serious eye damage Examples: Sodium Hydroxide (lye) and Sulfuric Acid Corrosive will appear on chemicals that have corrosive properties. Depending on the properties of the chemical(s) in the product, the corrosion pictogram can mean:

15. Labels – Pictograms (Health) • Harmful if swallowed • Acute Toxicity (harmful) • Harmful in contact with skin • Skin Sensitizer • Harmful if inhaled • Respiratory Tract Irritant • Causes skin irritation • Irritant (skin and eye) • Causes serious eye irritation • May cause allergic skin reaction • Hazardous to Ozone Layer Examples: Isopropyl Alcohol, Ethyl Alcohol, Acetone Exclamation Mark will appear on chemicals with less severe toxicity. This symbol will never be used with “skull and crossbones” symbol. Depending on the health hazard, it can mean:

16. Labels – Pictograms (Health) • Carcinogen • Mutagenicity • Reproductive Toxicity • Respiratory Sensitizer • Target Organ Toxicity • Aspiration Toxicity Examples: Carbon Monoxide, Hexanes Health Hazard will appear on chemicals with less severe toxicity. This symbol will never be used with “skull and crossbones” symbol. Depending on the health hazard, it can mean:

17. Labels – Pictograms (Health/Physical) Gas Cylinder can cause fires, explosions, oxygen deficient atmospheres, toxic gas exposures as well as the innate physical hazard associated with cylinders under high pressure • Gases under pressure • Compressed gases • Liquefied gases • Refrigerated liquefied gases • Dissolved gases Examples: Butane and Propane

18. Labels – Pictograms (Physical) Exploding Bomb symbol will appear on chemicals that have explosive properties. • Unstable Explosives • Self-reactive substances and mixtures • Organic peroxides Examples: Nitroglycerine and TNT, Gunpowder, Rocket propellants, and Pyrotechnic mixtures (fireworks).

19. Labels – Pictograms (Physical) • Extremely flammable gas • Extremely flammable aerosol • Self-Heating • Flammable aerosol • Extremely flammable liquid and vapor • Highly flammable liquid and vapor • Flammable liquid and vapor • Flammable solid Examples: Butane, Pyrophorics, Organic Peroxides Flame symbol will appear on chemicals that are flammable. Depending on the properties of the chemical(s) and the product, the flame can mean:

20. Labels – Pictograms (Physical) Flame over circle symbol will appear on chemicals that are: • Oxidizers • Oxidizing gases, liquids, and solids Examples: Hydrogen Peroxide and Nitrous Oxide

21. Labels – Pictograms (Environment) Environment symbol will appear on chemicals which are acutely hazardous to fish, crustacean, or aquatic plants. This is the only symbol that is not mandatory. • Aquatic Toxicity • Acute hazards to the aquatic environment • Chronic hazards to the aquatic environment

22. Label – Signal Word A Signal Word is used to indicate the relative level of severity of hazard and alert the reader to a potential hazard on the label. The signal words used are: • "Danger" - used for the more severe hazards • “Warning" - used for less severe hazards.

23. Labels- Hazard Statement A Hazard Statement describes the nature of the hazard(s) of a chemical, including where appropriate the degree of hazard. All of the applicable hazard statements must appear on the label.

24. Labels – Precautionary Statement A Precautionary Statement is a statement that describes recommended measures that should be taken to minimize or prevent adverse effects.

25. Label – What do UNC Employees need to do? Effective June 1 2015, all chemicals received at the University should have the required label. Any material transferred to another container must also have the same label versus just chemical/product name.

26. Safety Data Sheets HazCom 2012 requires Safety Data Sheets - SDS (formerly known as Material Safety Data Sheets – MSDS) to use a specified 16-section standardized format. Under the new format, employees wanting information regarding Exposure Controls/Personal Protection will always refer to Section 8 of the Safety Data Sheets.

27. Safety Data Sheets To improve employee understanding, information listed on the label, like Precautionary Statement, will be same information the employee will find on the Safety Data Sheet. The standardize 16 sections is broken down as follows:

28. Safety Data Sheet – 16 Sections • Identification of the substanceor mixture and of the supplier • Hazards identification • Composition/information on ingredients Substance/Mixture • First aid measures • Firefighting measures • Accidental release measures • Handling and storage • Exposure controls/personal protection • Physical and chemical properties • Stability and reactivity • Toxicological • Ecological information(non mandatory) • Disposal considerations(non mandatory) • Transport information(non mandatory) • Regulatory information(non mandatory) • Other information including information on preparation and revision of the SDS

29. Safety Data Sheets – What do UNC Employees need to do? By December 2015, distributors must provide the new format of Safety Data Sheets. Supervisors need to update the Safety Data Sheet notebooks and/or computer links in their job specific area to the newly format sheets. Remember SDS(s) must be accessible to employees at all times.

30. NC OSHA– Enforcement By June 2016, NC OSHA will begin to enforce compliance with HazCom 2012 by conducting site evaluations. Environment, Health and Safety will continue to assist University departments with the implementation of the specific requirements covered in this training.
