1 WHMIS Workplace Hazardous Materials Information System

2 “Right to Know” Worker’s have access to information through their employer.

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

4 Legislation Federal – –Bill C-70 – –Part of the Canada Labour Coded Provincial – Bill 79 – –Ontario Reg. 644/88 – –Occupational Health & Safety Act – –Policed by Ministry of Labour

5 Exemptions From WHMIS Explosives Drugs Pesticides Radioactive Materials Hazardous Wastes Products being transported – T.D.G. Act Consumer Products/Tobacco/Manufactured Articles

6 Three Components of WHMIS Labels – –Supplier Label – –Workplace Label Material Safety Data Sheets (MSDS) Worker Education

7 Duties of the Supplier Classify Product Apply Supplier Label Provide Material Safety Data Sheet Update MSDS’s at least every 3 years

8 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

9 Duties of a Worker Report missing or damaged labels or MSDS’s Participate in Training Apply Knowledge and Training

10 WHMIS Hazard Classifications

11 Class A Compressed Gas – –Any Hazardous Material that is contained under pressure including compressed gas, dissolved gas, or liquefied gas

12 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

13 Class B Flammable and Combustible Material – –Flammable Gases – –Flammable and Combustible Liquids – –Flammable Solids – –Flammable Aerosols – –Reactive Flammable Material Methanol, Toluene, Butane, Acetone

14 Flammable Materials Store liquids in Flammable Storage Cabinet Explosion-proof fixtures required NEVER store with oxidizers Keep away from heat, ignition sources, and direct sunlight Use static lines when transferring

15 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 Chlorates, Nitric Acid, Peroxides, Permanganates, Perchlorates, Nitrites, Nitrates

16 Oxidizers Easily oxidize metal powders, organic materials Segregate from other materials, such as organic solvents PPE and/or explosion barriers may be required

17 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

18 Class D2 Poisonous & Infectious 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.

19 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.

20 Class E Corrosive Material – –Material which may corrode aluminum and steel or human flesh – –Material which are anhydrous corrosive gases

21 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 Store on lower shelves

22 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 Store on lower shelves

23 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

24 WHMIS Labels

25 Supplier Label Product Identifier Hazard Symbols Border Bilingual Risk Phrases and Precautions First Aid Safe Handling Precautions Reference to MSDS Supplier Information

26 Workplace Label Product Identifier Safe Handling Precautions Reference to MSDS

27 Workplace Label Uses Transfer of material from a Supplier Labelled container to another container Replacement of a damaged Supplier Label

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