  • The acronym WHMIS tells you exactly what the system is for: it’s a system that provides information on hazardous materials in the workplace.
  • Whmis

    1. 1. WHMIS Workplace Hazardous Materials Information System Prepared by Peter-Jean Kennedy
    2. 2. Origin of WHMIS • WHMIS is a creation of three separate groups: • Federal Government • Provincial Governments • Industry (pay attention to this one!) • The goals of WHMIS are to: • Prevent injury and death • Provide information about the health effects of controlled products • Inform workers how to safely use controlled products
    3. 3. Controlled Products • Chemical products in the workplace are called “Controlled Products” • The term controlled products comes from the fact that use of these chemicals in the workplace are controlled by WHMIS regulations
    4. 4. Classes of Controlled Products • There are six classes, or types, of controlled products • Sometimes controlled products can belong to more than one class • Note: Copyright for the following definitions belongs to WorkSafeBC.
    5. 5. Compressed Gasses Class A This class includes compressed gases, dissolved gases, and gases liquefied by compression or refrigeration. If the pressure in the container is greater than 40 psi, the gas is a Class A product. The cylinder may explode if exposed to heat or to physical shock (i.e. when dropped). Examples: oxygen and acetylene in cylinders for welding
    6. 6. Flammable and Combustive Material Class B This class includes solids, liquids, and gases capable of catching fire in the presence of a spark or open flame under normal working conditions. Class B has six divisions 1. Flammable Gasses 2. Flammable Liquids 3. Combustible Liquids 4. Flammable Solids 5. Flammable Aerosols 6. Reactive Flammable Materials
    7. 7. Flammable Gasses Division 1 These are compressed gases (Class A) that form flammable mixtures in air. Examples: butane, propane, hydrogen gas At BUILD: Butane fuel cells for the Paslodes (Cordless Nailers)
    8. 8. Flammable Liquids Division 2 These are liquids that have flash points below 37.8°C. A flash point is the lowest temperature at which the vapours from these liquids will catch fire from nearby sparks or open flames. Examples: acetone, gasoline, isopropyl alcohol At BUILD: We use gasoline in our vehicles and generators
    9. 9. Combustible Liquids Division 3 These are liquids that have flash points of 37.8°C or more but less than 93.3°C. Examples: kerosene, mineral spirits, butyl cellosolve At BUILD: We sometimes use mineral spirits to clean tools
    10. 10. Flammable Solids Division 4 This is a special group of solids (usually metals) that meet very specific technical criteria such as the ability to cause fire through friction or to ignite and burn so vigorously and persistently that they create a hazard. Examples: various magnesium alloys, beryllium powder None at BUILD
    11. 11. Flammable Aerosols Division 5 These products are packaged in aerosol containers. Either the aerosolised product itself or the propellant may catch fire. Examples of flammable propellants: propane, butane, isobutane At BUILD:`WD-40 and many others
    12. 12. Reactive Flammable Materials Division 6 These products react dangerously in one of two ways: either (1) they spontaneously create heat or catch fire under normal conditions of use or they create heat when in contact with air to the point where they begin to burn, or (2) they emit a flammable gas or spontaneously catch fire when in contact with water or water vapour. Examples: aluminum alkyl compounds, metallic sodium, white phosphorous None at BUILD
    13. 13. Oxidising Material Class C These materials increase the risk of fire if they come in contact with flammable or combustible materials. Examples: perchloric acid, hydrogen peroxide At BUILD: Peroxide in our first-aid kits
    14. 14. Poisonous and Infectious Material Class D Class D products are often overlooked by people but, because of the serious harm they can cause, workers should pay very close attention to them. Class D has three divisions: 1. Materials causing immediate and serious toxic effects 2. Materials causing other toxic effects 3. Biohazardous infectious material
    15. 15. Materials Causing Immediate and Serious Toxic Effects Division 1 These materials can cause death or immediate injury when a person is exposed to small amounts. Examples: sodium cyanide, hydrogen sulphide At BUILD: Degreaser
    16. 16. Materials Causing Other Toxic Effects Division 2 These materials can cause life-threatening and serious long-term health problems as well as less severe but immediate reactions in a person who is repeatedly exposed to small amounts. Health problems include immediate skin or eye irritation, allergic sensitization, cancer, serious impairment of specific body organs and systems, and reproductive problems. Examples: xylene, asbestos, isocyanates At BUILD: Spray foam insulation
    17. 17. Biohazardous Infectious Materials Division 3 These materials contain harmful micro-organisms that have been classified into Risk Groups 2, 3, and 4 as determined by the World Health Organisation (WHO) or the Medical Research Council of Canada. Examples: cultures or diagnostic specimens containing salmonella bacteria or the hepatitis B virus At BUILD: Syringes
    18. 18. Corrosive Material Class E This class includes caustic and acid materials that can destroy the skin or eat through metals. Examples: sodium hydroxide, hydrochloric acid, nitric acid At BUILD: Perchloric Acid, Concrete
    19. 19. Dangerously Reactive Material Class F These products may self-react dangerously (for example, they may explode) upon standing or when exposed to physical shock or to increased pressure or temperature, or they emit toxic gases when exposed to water. Examples: plastic monomers such as butadiene; some cyanides None at BUILD
    20. 20. Exceptions • Some common products are not controlled by WHMIS regulations • wood or wood products; • tobacco or tobacco products; • manufactured articles; • products being transported if handled in accordance with TDG requirements; • hazardous waste; • explosives; • food and drugs; • pest control products, • consumer products (in small quantities and for home use only)
    21. 21. Break
    22. 22. Routes of Entry • There are only four ways chemicals can enter your body: 1. Ingestion 2. Inhalation 3. Absorption 4. Injection • Chemicals cannot harm you unless they can get inside your body!
    23. 23. So, how do we prevent chemicals from entering our bodies?
    24. 24. So, how do we prevent chemicals from entering our bodies? BY FOLLOWING THE INSTRUCTIONS ON LABELS AND MSDS.
    25. 25. Labels • There are two types of WHMIS labels 1. Supplier Labels 2. Workplace Labels • Each label is different and is used in different situations.
    26. 26. Supplier Labels The easiest way to identify a supplier label is the special border you see to the right. Nothing else in Canada is allowed to have this border. So, if you ever see this border, you know you’re looking at a supplier label.
    27. 27. Supplier Labels • Supplier Labels must have: • the name of the product, • the supplier's name and address, • a reference to the MSDS, • WHMIS Hazard Symbols, • risk phrases (eg. Spontaneously flammable in air), • precautionary measures (eg. Do not breathe dust), • first aid measures. • They must also be in English and French
    28. 28. Supplier Label
    29. 29. What is this chemical?
    30. 30. What is this chemical? This is why we use Workplace Labels!
    31. 31. Workplace Labels • Workplace labels are used when we take a product out of its original container • Workplace labels need four pieces of information on them: • the name of the product • a reference to the MSDS • precautionary measures • first aid measures
    32. 32. MSDS • MSDS means Material Safety Data Sheet • An MSDS will tell you how a product could hurt you • An MSDS will also tell you how to protect yourself
    33. 33. MSDS • MSDS are the most important source of information on controlled products • But, MSDS are often confusing and hard to read. • If you don’t understand an MSDS, ask your supervisor to explain it to you!
    34. 34. Worker Education • The most important element of WHMIS is worker education • Every worker in Manitoba must be trained in WHMIS before he uses a controlled product
    35. 35. Responsibilities • Everyone on a job site has responsibilities • Job site responsibilities are set out in the Workplace Safety and Health Act
    36. 36. Employer Responsibilites • Employers must • Ensure all workers are trained in WHMIS • Provide workers with information (i.e. Supplier Labels and MSDS) • Provide supervision
    37. 37. Supervisors’ Responsibilities • Supervisors must • Inform workers of safety risks • Ensure workers work safely
    38. 38. Workers’ Responsibilities • Workers must • Protect their own health and safety • Read and understand labels • Read and understand MSDS • Wear PPE • Protect the health and safety of other workers • Inform other workers of risks
