  2. WHMIS • WHMIS stands for Workplace Hazardous Materials Information System • The purpose of WHMIS is to reduce injury, illness or disease caused by exposure to hazardous materials.

  3. New to WHMIS • Globally Harmonized System of Classification and Labelling of Chemicals (GHS) has been adopted • There are now WHMIS symbols and Hazardous Household Products symbols • Material Safety Data Sheets (MSDS) are now called Safety Data Sheets (SDS); with no expiry dates

  4. Chemicals in your daily life have characteristics that make them useful, hazardous, or both. • Some types of matter that you use everyday can be hazardous • Information labels give you information about how to properly handle matter

  5. Chemical Safety Around the House/Work/Lab • Hazardous Household Products Symbols (HHPS) • Each symbol has two types of warnings: • Whether the hazard is the container or contents • The type of hazard

  6. HHPS: The Borders • Dangerous Container • Border looks like a traffic yield sign • Container is dangerous

  7. HHPS: The Borders • Dangerous Product • Border looks like a traffic stop sign • Contents of the container are dangerous

  8. HHPS: The Hazards • Explosive • Container can explode • If punctured or heater, pieces can cause serious injuries

  9. HHPS: The Hazards • Corrosive • Product inside the container will burn the throat or stomach if swallowed • Burn skin or eyes or contact

  10. HHPS: The Hazards • Flammable • Product will catch on fire easily if near sparks, flames, or heat

  11. HHPS: The Hazards • Poisonous • Product will cause illness or death if you eat or drink it • Smelling or licking the product may be enough to cause harm

  12. HHPS: Household Hazardous Product Symbols

  13. Discussion Questions • What is the HHPS system? Why is it used? • Which HHPS would be on spray paint?

  14. WHMIS Symbols • WHMIS uses a diamond shape around the hazardous classification

  15. WHMIS Symbols • Flammable • Product will catch on fire easily if near sparks, flames, or heat

  16. WHMIS Symbols • Oxidization • Has the ability to combine with oxygen and create an explosion or fire.

  17. WHMIS Symbols • Compressed Gas • Has the ability to exploded as the contents are under high pressure.

  27. SDS Sheets • Handling and Storage • Exposure controls/personal protection • Physical and chemical properties • Stability and reactivity • Toxicological information • Ecological information • Disposal considerations

  28. SDS Sheets • Transport information • Regulatory information • Other information
