  1. The Globally Harmonized System of Classification and labeling of chemicals (GHS)

  2. What is the GHS? • A world-wide approach to defining and classifying hazards, and communicating information on labels and safety data sheets.

  3. The Scope of the GHS • Covers all hazardous chemical substances, dilute solutions, and mixtures. • Requires chemical manufacturers, suppliers, and distributors to standardize hazardous classification criteria, labels, and safety data sheets. • Hazard Communication • Labels • Safety Data Sheets

  4. Key Label Elements Product identifier Supplier identifier Chemical identity Hazard pictograms Signal words Hazard statements Precautionary information

  5. Pictogram Shape and Colour • Pictograms will have a black symbol on a white background with a red diamond frame. A black frame may be used for shipments within one country.

  6. GHS Pictograms !

  7. Signal Words “Danger” or “Warning” • Used to emphasize hazard and discriminate between levels of hazard.

  8. Hazard Statements • A single harmonized hazard statement for each level of hazard within each hazard class • 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

  9. Precautionary Information • Label should include precautionary information describing recommended measures to minimize or prevent adverse effects from chemical exposure.

  10. Role of the Safety Data Sheet in the GHS • The Safety Data Sheet should provide comprehensive information about a chemical substance or mixture. • Employers and employees use the Safety Data Sheet as a source of information about hazards and to obtain advice on safety precautions.

  11. Safety Data Sheets Transition • Replace current Material Safety Data Sheets by requesting Safety Data Sheets from all suppliers

  12. Safety Data SheetFormat: 16 headings 1. Identification 2. Hazard(s) 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

  13. Safety Data Sheet Format: 16 headings (cont.) 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
