  1. WHMIS Workplace Hazardous Materials Information System

  2. Reasons for WHMIS • Designed after the US model called the “Right to Know” law. • Conveys knowledge of hazardous chemicals to workers who use them in their jobs. • Designed to reduce injuries and time lost due to exposure to hazardous chemicals.

  3. Workplace Education

  4. Supplier Responsibilities • Classify and label supplied materials • Provide current MSDS • Provide source for data on toxicity of a material

  5. Employer Responsibilities MSDS Training Labels

  6. Employer Responsibilities • Make sure MSDS is up-to-date • Add new information • Have MSDS available • Make sure workers understand • Have MSDS information available for medical personnel

  7. Employee Education Program • Assign ownership • Set up check system • Make sure copy of program is available • Schedule employees for training • Set up training records • Review program once per year

  8. Employee Testing Procedures • Give employees a written test • Conduct a hands-on demonstration • Set up a mock emergency and test the response

  9. Hazardous Chemicals

  10. Some Hazardous Chemicals… • Undercoats & Topcoats • Hardeners • Buffing Compounds • Cleaners • Solvents • Body fillers • Welding gases • Adhesives

  11. Employee Responsibilities • Know and understand labels • Follow label directions • Follow safe-use procedures • Know MSDS information • Know emergency procedures • Avoid removing or defacing labels • Inform employer of missing information • Wear required equipment • Help develop safety plan

  12. Overexposure Effects • Acute Exposure • Burns • Dizziness • Nausea • Coughing • Chronic Exposure • Nerve Damage • Lung Scarring

  13. Hazardous Materials Categories • Irritants • Corrosives • Toxins • Poisons • Carcinogens • Chemicals that cause cancer • Allergenics • Chemicals that cause an allergic reaction

  14. Lung Irritants • Chemicals that affect the: • Lungs and nasal passages • Skin • Eyes

  15. Irritant Reaction • Itching • Burning • Rashes • Found in: • Epoxy repair materials, plastic bonding adhesives, undercoatings, cleaners, hardeners and reducers, body fillers

  16. Corrosive Materials • Can cause skin burns and respiratory problems • Are found in many cleaning products and metal preparation materials • Are either highly acidic or highly alkaline • Examples include: • Paint strippers, prep solvents, wire wheel cleaners, sulphuric acid in batteries, oxalic acid, full-strength degreasers

  17. Nervous System Effects • Dizziness • Headaches • Nausea • Blurred vision • Poor coordination

  18. Toxins • Toxins can be broken down into: • Mild neurotoxins • Liver toxins • Reproductive toxins • Blood toxins

  19. Mild Toxins • Mild neurotoxins cause central nervous system depression and destroy nerve endings. • The effects of this condition are similar to drinking too much alcohol. • Effects include: • Dizziness, headaches, nausea, blurred vision, poor coordination

  20. Liver Toxin Exposure • Exposure to liver toxins comes from breathing vapors while:

  21. Liver Toxin Chemicals • Examples include: • Toluene, xylene, butyl acetate, lead chromates, nickel compounds, methylene chloride. • Found in some: • Urethane enamels • Adhesives

  22. Reproductive Toxins • May cause birth defects • Birth defects can vary from minor to severe • Materials that may contain reproductive toxins include: • Products containing toluene • Gasoline • Products containing lead compounds • Acrylic lacquers • Urethane enamels

  23. Blood Toxins • Destroy or deform red blood cells • Red blood cells carry oxygen through the blood stream. Destroying or deforming red blood cells reduces the amount of oxygen being carried through the blood stream • Overexposure may cause difficult breathing or loss of consciousness • Materials that may contain blood toxins include: • Some aerosol cleaners and enamel clear coats

  24. Carcinogens • Examples of carcinogenic materials include:

  25. Allergens • May cause people to react to certain chemicals. • Normally do not cause a reaction when first exposed. The reaction starts with the second exposure. • Each person will have a different reaction to different materials. • Some materials contain chemicals that are more likely to cause reactions than others.

  26. Examples of allergens • Acrylic sealers • Adhesives • Sealers • Epoxy resins • Clear coats • Hardeners • Activators

  27. Routes of Entry • Breathing • Swallowing • Absorption through skin • Injection through skin

  28. Breathing Hazardous Materials • Most common way of entering the body. • Starts when products being mixed, poured, or used, give off vapors or dust particles. • Causes them to collect in the lungs and be absorbed into the blood stream. • Can be prevented by wearing a proper respirator.

  29. Ingesting Hazardous Chemicals • Swallowing is the second most common way hazardous materials enter the body. • Ingestion can occur by: • Not washing before eating. • Eating or drinking in an area where hazardous materials are used. • Biting fingernails. • Touching the mouth while coughing or sneezing. • Smoking after handling hazardous materials.

  30. Absorption Through Skin • Hazardous materials can be absorbed through the skin. Skin is porous, like a sponge.

  31. Absorption Through Skin • Absorption occurs by: • Skin contact, such as picking up a solvent-soaked cloth. • Washing hands with gasoline or other solvent. • Floor cleaning materials splashing into shoes. • Always wear protective equipment such as: • Gloves • Aprons • Boots

  32. Absorption Through Eyes • Hazardous materials can also enter eyes through exposure to hazardous: • Vapors • Dust • Spills • Wear safety goggles to help prevent eye exposure.

  33. Injection in Skin • Hazardous material can enter the body through injection. This can be caused by a material: • Entering through a broken cut or a skin rash. • Being forced through the skin by air tools or cleaning equipment. • Prevent injection by: • Covering and protecting open cuts or sores. • Following recommended safety procedures when working with tools and cleaning equipment.

  34. Review Question #1 • Technician A says that lethal exposure to hazardous materials can occur from biting fingernails or not washing before eating. Technician B says that lethal exposure can occur from breathing the vapors or dust of a hazardous material. Who is right? A. Technician A only B. Technician B only C. Both Technician A and Technician B D. Neither Technician A or Technician B

  35. Review Question #2 • Hazardous materials can enter the body by: A. Swallowing the material B. Absorbing the material through the skin C. Injecting the material into the skin D. All of the above

  36. Product Labels • All materials in the workplace are required to have a label. Labels are an important source of information that may include: • The name of the material • Part number

  37. Product Labels (Cont’d) • Possible hazards when using the material • Hazard symbols • A statement that the MSDS is available • How to safely handle the material Suggestions for first aid treatment • The manufacturer’s name, address, and emergency telephone number • The intended use of the product

  38. Minimum Label Requirements • Labels for hazardous materials are required to provide: • A product identifier or name. • Hazard warnings. • A statement that the MSDS is available.

  39. What If There Is No Label? • Do not handle the product. • Determine the nature of the material from the shop manager. • Place a label on the container once the material has been identified.

  40. Hazard Symbols • Hazard symbols on product labels are in picture form so they can be read in any language. The symbols show an immediate hazard warning about the contents of the container. Examples are: • Cylinder • Flame • Skull and crossbones inside a circle • Hand being corroded by a chemical

  41. Compressed Gasses • White cylinder on a green background

  42. Flammable and Combustible • Flame on a red background

  43. Oxidizing Material • Flame over a circle on a yellow background

  44. Immediate Toxic Effects • Causes immediate and serious (acute) toxic effects • Skull and crossbones on a white background

  45. Other Toxic Effects • Causes other toxic effects. • Letter ‘T’ with a dot below it.

  46. Biohazardous Materials • Four overlapping circles.

  47. Corrosive Materials • Hand and piece of material being corroded by a liquid.

  48. Dangerously Reactive Materials • Letter ‘R’ with a test tube in the middle.

  49. Risk Phrases • Examples of risk phrases: • Explosive • Flammable • Lung irritant • Causes burns • May cause birth defects • Reacts violently with water • May cause cancer

  50. Personal Protection Symbols • Some workplace labels include personal protection symbols that can be checked.
