  3. Purpose of WHMIS • Provides Information on Hazardous Materials used in the Workplace • Identify Workplace Hazards • Consistency in all Canadian Workplaces

  4. Responsibilities Under WHMIS • Duties of the Supplier • Classify Product • Apply Supplier Label • Provide Material Safety Data Sheet

  5. Responsibilities Under WHMIS • Duties of the Employer • Conduct Workplace Inventory • Ensure Proper Labeling is Used • Label Piping Systems/Vessels/Reactors • Maintain and Make Available MSDS’s • Train Workers

  6. Responsibilities Under WHMIS • Duties of a Worker • Participate in Training • Apply Knowledge and Training • KEEP YOURSELF SAFE!!

  7. “Right to Know” • Worker’s have Access to Information through their Employer • Public has Access to Information through Local Medical Officer of Health

  8. WHMIS Hazard Classifications

  9. Compressed Gas • Any Hazardous Material that is contained under pressure including compressed gas, dissolved gas, or liquefied gas

  10. Compressed Gas Cylinders • store and transport with safety cap, because… • comply with storage restrictions, because… • DO NOT store fuel gas with oxygen, because… • secure in an upright position, because… • use in a well ventilated area, because… • use the proper type of regulator and know its history, because…

  11. Flammable and Combustible Material • Flammable Gases • Flammable and Combustible Liquids • Flammable Solids • Flammable Aerosols • Reactive Flammable Material

  12. Flammable Materials • Store liquids in Flammable Storage Cabinet • Explosion-proof fixtures required • Pour larger quantities in fume hood • NEVER store with oxidizers • Keep away from heat, ignition sources, and direct sunlight • Use static lines when transferring

  13. Oxidizing Material • Any Hazardous Material which causes or contributes to the combustion of another material by giving oxygen or some other oxidizing substance, whether or not it is combustible. • Eg. Pool & spa test strips, ozone, bleach…

  14. Oxidizers • Easily oxidize metal powders, organic materials • Segregate from other materials, such as organic solvents • PPE and/or Explosion barriers may be required

  15. Poisonous & Infectious Materials (Class 1) • Material causing immediate and serious toxic effects • Materials which are potentially fatal or may cause permanent damage if inhaled, swallowed, or absorbed through the skin, or may burn the skin or eyes upon contact

  16. Poisonous & Infectious Materials (Class 2) – Toxic Materials • Material causing other chronic or long term effects • Material which may cause death or permanent damage as a result of repeated exposure over an extended period of time; may be an irritant to the skin, eyes, or respiratory system; may cause cancer, birth defects, or sterility.

  17. Poisonous & Infectious Materials (Class 3)- Biohazards • Materials which may cause disease in humans and animals, such as viruses, bacteria, and fungi; may also include cultures and diagnostic specimens such as blood, urine, and body tissue.

  18. Corrosive Material • Material which may corrode aluminum and steel or human flesh • Can be liquid or gases

  19. Dangerously Reactive Material • Materials which become self-reactive under conditions of shock, or increased temperature or pressure • Materials which react vigorously with water to produce a very toxic gas

  20. General Dry Chemicals Relatively innocuous or unreactive No special storage requirements

  21. Chemical Compatibility • Never store incompatible materials together • Vapours will react • Use a Chemical Compatibility Chart

  22. Quiz time!

  26. WHMIS “Name that Symbol” Oxidizers Compressed Gas

  27. WHMIS Labels

  28. Supplier Label • Product Identifier • Hazard Symbols • Border • Risk Phrases and Precautions • First Aid, Supplier Information • Precautions • Safe Handling Precautions • Reference to MSDS

  29. Workplace Label • Product Identifier • Safe Handling Precautions • Reference to MSDS

  30. Typical Workplace Labels

  31. Hazardous Ingredients Preparation Information Fire & Explosion Hazard Toxicological Properties First Aid Measures Product Information Physical Data Reactivity Data Preventative Measures MSDS Contents

  32. Product Information • Product Identifier • Manufacturer’s/Supplier’s Name and Address • Emergency Telephone Number • Product Use

  33. Odour Threshold Vapour Pressure Coefficient of Water/Oil Distribution Boiling Point (oC) and Freezing Point (oC) Evaporation Rate (Butyl Acetate=1) Physical State Odour & Appearance Specific Gravity (Water=1) Vapour Density (Air=1) pH Percent Volatile (by volume) Physical Data

  34. Fire & Explosion Hazard • Conditions of Flammability • Means of Extinction • Sensitivity to Mechanical Impact • Sensitivity to Static Discharge • Flashpoint (oC) and Method • Upper and Lower Flammable Limits (%) • Autoignition Temperature (oC) • Hazardous Combustion Products

  35. It’s all about a safe workplace!

  36. Spot the Hazards
