  3. Introduction to Whmis WHMIS is Canada-wide legislation, dealing with controlled products in the workplace. *A controlledproduct is ‘any product, material or substance included in any one of the classes listed in the Hazardous Products Act (HPA).’ 2003 3

  4. WHMIS is Designed to Solve the Problem of: • Unlabelled materials in the workplace • Inadequate or contradictory information being given to employers/workers regarding identification, hazardous properties and precautions to be taken with hazardous materials used in the workplace 2003 4

  5. Three Components of WHMIS • Labels on hazardous materials or their containers • MSDS or material safety data sheets which are technical bulletins providing more detailed information than the label • Worker education, providing instruction on hazards and safe work procedures 2003 5

  6. JHSC input Producer Supplier label Supplier Informed worker Employer Worker Training MSDS Importer Flow of Information 2003 6

  7. Labels Two Types: • Supplier labels (developed and provided by the supplier) • Workplace labels (developed and used in the workplace) 2003 7

  8. Supplier label: Design and Application 1 of 3 • Content layout: not legislated • Border: specific • Colour: not legislated • Legibility: distinct; good contrast • Durability: able to withstand normal use • Application: imprinted; stenciled; attached • Language: English and French 2003 8

  9. Supplier Label: Required Statements 2 of 3 1. Product Identifier 2. Hazard Symbols 3. Risk Phrases 4. Precautions 5. First Aid 6. Supplier Information 7. Reference to MSDS 2003 9

  10. Supplier Label 3 of 3 2003 10

  11. What Does This Symbol Mean? 1 of 2 2003 11

  12. What Do We Know? 2 of 2 Compressed Gas (Class A): • Poses an explosion danger because the gas is under pressure • Container may explode if heated in a fire, or dropped • examples include: compressed air, carbon dioxide, propane, oxygen, ethylene oxide, and welding gases 2003 12

  13. What Does This Symbol Mean? 1 of 2 2003 13

  14. What Do We Know? 2 of 2 Combustible and Flammable Material (Class B): • Will burn and is therefore a potential fire hazard • May burn at relatively low temperatures; flammable materials catch fire at lower temperatures than combustible materials • May burst into flame spontaneously in air, or release a flammable gas on contact with water • May cause a fire when exposed to heat, sparks, or flames, or as a result of friction • Common examples include: propane, butane, acetylene, ethanol, acetone, turpentine, toluene, kerosene, Stoddard solvent, spray paints and varnish. 2003 14

  15. What Does This Symbol mean? 1 of 2 2003 15

  16. What Do We Know? 2 of 2 Oxidizing Material (Class C): • Poses a fire and/or explosion risk in the presence of flammable or combustible material • May react violently when it comes into contact with combustible materials such as fuels or wood • May burn skin and eyes upon contact • Oxidizers can also be in the form of gases (oxygen, ozone), liquids (nitric acid, perchloric acid solutions) and solids (potassium permanganate, sodium chlorite). 2003 16

  17. What Does This Symbol Mean? 1 of 2 2003 17

  18. What Do We Know? 2 of 2 Poisonous and Infectious Material (Class D, Division 1): • Is a potentially fatal poisonous substance • May be fatal or cause permanent damage if it is inhaled or swallowed or if it enters the body through skin contact • May burn eyes or skin upon contact • Examples of some D-1 materials include carbon monoxide, sodium cyanide, sulphuric acid, toluene-2,4-diisocyanate (TDI), and acrylonitrile. 2003 18

  19. What Does This Symbol Mean? 1 of 2 2003 19

  20. What Do We Know? 2 of 2 Poisonous and Infectious Material: Other Toxic Effects (Class D, Division 2): • Not immediately dangerous to health • May cause death or permanent damage as a result of repeated exposure over time • May be a sensitizer, which produces an allergy • May cause cancer, birth defects, or sterility • Examples include: asbestos fibres, mercury, acetone, benzene, quartz silica (crystalline), lead and cadmium. 2003 20

  21. What Does This Symbol Mean? 1 of 2 2003 21

  22. What Do We Know? 2 of 2 Poisonous and Infectious Material: Biohazardous, infectious material (Class D, Division 3): • May cause a serious disease resulting in illness (AIDS, Hepatitis) or death • Can also include tetanus protection • Examples of biohazardous infectious materials include the AIDS/HIV virus, Hepatitis B and salmonella. 2003 22

  23. What Does This Symbol Mean? 1 of 2 2003 23

  24. What do We Know? 2 of 2 Corrosive Material (Class E): • Causes severe eye and skin irritation upon contact • Causes severe tissue damage with prolonged contact • Often produces vapor or fumes that may be harmful if inhaled • Common corrosives include acids such as sulphuric and nitric acids, bases such as ammonium hydroxide and caustic soda and other materials such as ammonia gas, chlorine, and nitrogen dioxide. 2003 24

  25. What Does This Symbol Mean? 1 of 2 2003 25

  26. What Do We Know? 2 of 2 Dangerously Reactive Material (Class F): • Is very unstable • May react with water to release a toxic or flammable gas • May explode as a result of shock, friction or an increase in temperature • May explode if heated when in a closed container • Undergoes vigorous polymerization • Examples of these products are ethyl acrylate, vinyl chloride, ethylene oxide, picric acid and anhydrous aluminum chloride. 2003 26

  27. Workplace Labels 1 of 2 • Methanol • Avoid inhaling vapours, handle with care • Flammable • Avoid eye and skin contact • See MSDS for more information • Product Identifier • Information on safe handling of the product • Reference to MSDS 2003 27

  28. Workplace Labels 2 of 2 • Must be displayed to give clear warning to employees • May be a label, tag, sign or other • Is not required to be bilingual; can be in the language of the workplace 2003 28

  29. Material Safety Data Sheets 1 of 3 The MSDS is: • A technical information reference for worker education and control measures • A document which can be distributed 2003 29

  30. Material Safety Data Sheets 2 of 3 The MSDS is NOT: • All the information needed for the safe use of a product in every possible situation • A document only to be read and filed 2003 30

  31. MSDS Required Criteria 3 of 3 1. Product Identifier 2. Ingredients 3. Physical Data 4. Fire and Explosion Hazards 5. Reactivity Data 6. Toxicological Properties 7. Preventive Measures 8. First Aid Measures 9. Preparation Information 2003 31

  32. Worker Education 1 of 2 Anyone working with or nearby controlled products must be trained in hazard information and procedures regarding: • Safe use • Storage • Handling • Disposal • Emergency procedures 2003 32

  33. Supplier Responsibilities Supplier responsibilities are found under the Hazardous Products Act (Federal Bill C-07) Suppliers Must: I. Label controlled products intended for workplace use II. Supply MSDS with each controlled product 2003 33

  34. Employer Responsibilities • The employer’s WHMIS responsibilities are outlined in Provincial Regulation 88-221: • To obtain MSDS from supplier • Ensure appropriate labeling (supplier and workplace) • Provide adequate instruction and training to employees • Sort and file the MSDS in a clearly indicated and easily accessible area 2003 34

  35. Summary 1 of 2 • Labels • MSDS • Worker Education WHMIS has three components: • Compressed Gas • Flammable • Oxidizers • Poisons • Corrosives • Reactive WHMIS is a hazard class driven system 2003 35

  36. Summary 2 of 2 Employers must train their workers to use the information provided by • Labels • MSDS Training should be reviewed and/or updated Yearly, or as conditions change 2003 36
