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 unreactiveRelatively innocuous or unreactive No special storage requirementsNo special storage requirements Relatively innocuous or unreactiveRelatively innocuous or unreactive No special storage requirementsNo special storage requirements
