  1. WHMIS

  2. Purpose of WHMIS • Workplace Hazardous Materials Information System • Provides Information on Hazardous Materials used in Workplace • Facilitates the Process of Hazard Identification • Ensures Consistency of Information in all Canadian Workplaces

  3. Federal Legislation:

  4. Ontario Legislation:

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

  6. 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

  7. Responsibilities Under WHMIS • Duties of a Worker • Participate in Training • Apply Knowledge and Training

  8. Exclusions Under WHMIS • The Explosives Act • The Food and Drug Act • The Pest Control Product’s Act • The Atomic Energy Control Act • Hazardous Wastes • Consumer Products/Tobacco/Manufactured Articles

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

  10. Trade Secret Protection • Hazardous Materials Information Review Commission • Tripartite

  11. Trade Secret Protection • Criteria • Information Known Outside Business • Information Known Inside Business • Measures Taken to Guard Secrecy • Value of Information to Firm or Competition • Financial Expenditures

  12. Information Delivery • Labels • Supplier Label • Workplace Label • Material Safety Data Sheets (MSDS) • Worker Education

  13. WHMIS Hazard Classifications

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

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

  16. Class B • Flammable and Combustible Material • Flammable Gases • Flammable and Combustible Liquids • Flammable Solids • Flammable Aerosols • Reactive Flammable Material

  17. Flammable Materials • Methanol, Toluene, Butane, Ethanol • Store liquids in Flammable Storage Cabinet • Store minimum quantities in lab • Explosion-proof fixtures required • Decant in large quantities in fume hood • NEVER store with oxidizers • Keep away from heat, ignition sources, and direct sunlight • Use static lines when transferring • Refrigerator must meet NFPA Standard 56C ( Flammable Material Storage Units)

  18. Class C • 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. • Organic Peroxides

  19. Oxidizers • Chlorates, Nitric Acid, Peroxides, Permanganates, Perchlorates, Nitrites, Nitrates • Easily oxidize metal powders, organic materials • Keep minimum quantities in lab • Segregate from other materials, such as organic solvents • Use a glass-heating mantle or sand bath to heat material • PPE and/or Explosion barriers may be require

  20. Perchloric Acid • Perchlorate salts are explosive • Use a perchloric acid fume hood • Wash down fume hood after use • Never store with organic chemicals especially alcohols and glycerol • Store in a ceramic tray

  21. Organic Peroxides • Some are very unstable • Sensitive to heat, friction, impact, sparks, light • Use minimum quantities in lab • NEVER replace unused peroxides into original container • NEVER use a metal spatula to handle peroxides • Refrigerate to minimize decomposition

  22. Peroxide Formers • Have caused several severe laboratory explosions • Contributing Factors: Oxygen, Light, Storage Time • Visual Identifiers: Crystals, Floating wisp-like structures • Date and Dispose of within 1 year

  23. Common Chemicals forming Peroxides • Diethyl ether • Tetrahydrofuran • Dioxane • Methyl isobutyl ketone

  24. Class D1 • Poisonous & Infectious Materials • 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

  25. Class D2 • Poisonous & Infectious Materials • Material causing other chronic or long term effects • Material which may cause dealth 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.

  26. Class D3 • Poisonous & Infectious Materials • Biohazardous and Infectious Materials • 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.

  27. Class E • Corrosive Material • Material which may corrode aluminum and steel or human flesh • Material which are anhydrous corrosive gases

  28. Inorganic Acids • Sulfuric Acid, Nitric Acid, Perchloric Acid, Hydrochloric Acid • Segregate from bases and organic compounds • Store in a ventilated acid cabinet • Know the location of eye washes and safety showers • Use a safety carriers • Store on lower shelves

  29. Bases • Sodium hydroxide, Ammonium hydroxide • Segregate from acids and organic compounds • Store in a ventilated cabinet • Know the location of eye washes and safety showers • Use a safety carrier • Store on lower shelves

  30. Hydrogen fluoride • Is extremely corrosive • Dissolves glass • Absence of immediate pain, penetration can be extensive, leading to serious injury or death • Causes severe eye irritation and skin burns

  31. Class F • Dangerously Reactive Material • Materials which undergo vigorous polymerization, decomposition, or condensation • 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

  32. Ethylene Oxide • Used as a Sterilant at hospital • Extremely flammable • Supplies its own oxygen/Chemically decomposes • Highly Reactive • Very Corrosive • Human Carcinogen

  33. Water Reactive Materials Sodium metal, acid and metal anhydrides, calcium, phosphorous pentachloride, aluminum chloride-anhydrous Special storage requirements

  34. Pyrophoric Materials Air reactive White phosphorus, diborane, diethyl aluminum chloride, lithium Store under an inert atmosphere such as nitrogen

  35. Cryogenic Materials Liquid Nitrogen Never use to cool substances which are combustible in air - explosion risk from condensation of oxygen from air Use insulated gloves and face shield Keep cryogenic substances in containers which are not tightly closed to prevent explosive pressure build-up Use only equipment designed for cryogenic materials

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

  37. Chemical Compatibility • Never store incompatible materials together • Vapours will react • Chemical Compatibility Chart

  38. WHMIS Labels
