  1. WHMIS

  2. WHSCC/Cssiat W H M I S Workplace Hazardous Materials Information System 2003 2

  3. 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 8

  4. In the Workplace, What is the “Key” to Everyday WHMIS? ? HAZARD SYMBOLS! 2003 14

  5. What Does This Symbol Mean? 1 of 2 2003 15

  6. 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 2003 16

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

  8. 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 2003 18

  9. What Does This Symbol mean? 1 of 2 2003 19

  10. 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 2003 20

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

  12. 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 2003 22

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

  14. 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 2003 24

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

  16. 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 2003 26

  17. What Does This Symbol Mean? 1 of 2 2003 27

  18. 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 2003 28

  19. What Does This Symbol Mean? 1 of 2 2003 29

  20. 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 2003 30

  21. 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 49

  22. WHMIS Responsibilities Suppliers, employers and employees each have a role to play in making WHMIS work. 2003 53

  23. 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 59
