This presentation provides an overview of WHMIS (Workplace Hazardous Materials Information System) for technology and dual-credit students. WHMIS is a nationwide system that provides information on hazardous materials in the workplace. It involves both federal and provincial legislation to balance workers' right to know with industry confidentiality. The key elements of WHMIS are labels, material safety data sheets, and worker training. Hazardous materials can enter the body through inhalation, absorption, injection, or ingestion and can have acute or chronic health effects.

3. Purpose of WHMISThe Workplace Hazardous Material Information System (WHMIS) is a nationwide system to provide information on hazardous materials used in the workplace and involves both Federal and Provincial legislation.WHMIS recognizes the interests of workers, employers, suppliers and regulators, balancing the workers' right to know with the industry's right to protect confidential business information.

4. Hazardous Products Act (HPA)Federal legislation is the Hazardous Products Act (HPA)HPA controls product regulations and ingredient disclosure listsProvincial legislation is the Occupational Health and Safety Act (OHSA)OHSA is in charge of WHMIS regulations and references parts of the controlled product regulations

5. Key Elements Three Key Elements of WHMIS are:1. Labels 2. Material Safety Data Sheets3. Worker Training

6. Why we need to KnowExposure to hazardous material can cause or contribute to a variety of health effects such as:Irritation, burns

7. Sensitization

8. Heart ailments

9. Kidney & lung damage

10. CancerWhy we need to KnowSome materials may also be safety hazards that can contribute to fires, explosions, & other accidents if improperly handled or stored.

11. One in four Canadian workers is exposed to chemical hazards on the job.Occupational Health & Safety ActIn Ontario workplace safety is a provincial responsibility.The OHSA outlines the responsibilities of the Employer, Supervisor and Employee.The OHSA gives the worker three main rights:Participate

12. Refuse unsafe work

13. The right to knowWHMISWHMISisbased on the tripartite model regulation, was adopted under the OHSA; this regulation sets out the employer duties under WHMIS. The Act also covers three other directly related areas: Public Right To Know

14. Workplace Inventories

15. Hazardous Physical AgentsMain Responsibilities Under WHMISDetermine which of their products are controlled products.Provideinformation about controlled products in the form of labels and MSDS

16. Labelsmust be in English and French.

19. Provision of information in medical emergencies

20. Assess products produced in-house and establish a WHMISprogram

21. Labels: create and apply

22. Worker education and training.Employer/Supervisor

23. Worker ResponsibilityUse PPE requiredReport hazards and/or non-compliance to supervisorAttend training sessionsUse and understand any information provided

24. Flow of Information

25. WHMIS ExemptionsCertain products are exempt from the requirements of the legislation. Hazardous wastes must be labeled in some fashion and workers need to know how to store & handle safelySome are partially exempt and some are completely exempt but still require WHMIS label for safe use.Examples of Partially Exempt: Explosives, cosmetics, drugs.Completely Exempt: Tobacco, wood or wood products

26. Occupational HealthStates of MatterHazardous materials can be present in many forms including: gases; mists; vapours; fumes; dusts; & smoke.

27. Definitions of MatterFume/dust/smoke are tiny particles of a solid suspended in air

28. Mist are tiny particles of a liquid suspended in air

29. Vapoursare a gaseous form of a material that is normally a liquid at room temperature and pressureHazardous Materials There are many materials used in the workplace that can be hazardous.There are also Physical Hazards which include such things as noise, vibration and radiation.However, in order for them to have an affect, they must contact or enter the body.

30. Routes of EntryThere are four main routes that a hazardous material can enter the human body. InhalationHazardous material becomes inhaled (most common)AbsorptionAbsorbed through the skinInjectionHazardous material entering the body through accidental penetration of the skinIngestionSwallowed, toxic substances can enter the digestive tract

31. Routes of ExitThere are several routes of exit in the body for hazardous substances. Two key body organs, the liver and kidneys, play a major role in detoxification and balancing the body's systems. They play vital roles in eliminating hazardous substances.

32. The Body and Health Effects

33. Toxicity Is the ability of a substance to produce an undesired effect when it has reached a sufficient concentration at a certain site in the body.LatencyLatency refers to the time lag between exposure to a hazardous material and the eventual development of the disease. This can be 10 years for example and, on average is considered to be 20 years.

34. Chronic vs. Acute ExposureExposure can be classified as chronic or acute. In chronic exposures, the dose is delivered at some frequency (daily or weekly usually) over a period of time. In acute exposures, the dose is delivered in a single event and absorption is rapid

35. Results of Exposure Exposure to hazardous materials can cause damage to the DNA in the body's cellsDefinitions...Carcinogen: A substance or physical agent that can cause cancer in humans. e.g. - Asbestos.Mutagen: A substance or physical agent that can cause changes in one or more heredity features by modifying genes. e.g. - Ionizing radiation. Teratogen: A substance capable of causing changes to the developing fetus. e.g. Thalidomide.

36. Classes ofChemicals and Divisions6 Classes, 8 SymbolsClass D has 3 divisionsA - Compressed GasB - FlammableC - OxidizingD - ToxicE - CorrosiveF - Dangerously Reactive

37. SYMBOLS

38. Class A: Compressed GasesWHMIS treats all compressed gases as controlled products. Gases which are also flammable, toxic or have other hazardous properties will also be found in other classes. Class B: Flammables and Combustible MaterialWHMIS groups together into a single class all those chemicals that pose a fire hazard. There are six subdivisions to the flammable and combustible materials class. Chemicals covered by any of the subdivisions all carry the same stylized flame symbol.

39. Class C: Oxidizing Materials Some chemicals called oxidizers can provide oxygen that can increase the risk that a fire will break out. Once a fire is underway, oxidizers can use the fire to burn more intensely. Class D: Poisonous & Infectious Materials Class D: Division 1 – Materials Causing Immediate and Serious Toxic EffectsMaterials included in this subdivision are generally those highly toxic chemicals that cause death within a short period following exposure.

40. Class D: Division 2 – Materials Causing Other Toxic EffectsWHMIS places chemicals that irritate the skin and eyes and chemicals that present a long term health risk, in a separate class. Class D: Division 3 – Bio hazardous Infectious MaterialsBio hazardous infectious materials are classified as those which, when they come into contact with the body, are organisms or toxins from organisms that may cause serious infectious disease or the effects of a disease.

41. Class E: Corrosive MaterialWHMIS groups together chemicals that can corrode metal or destroy skin into a corrosive materials class. Included in the class are many of the common acids such as sulphuric acid, (used in automotive batteries) Class F: Dangerously Reactive Material The last WHMIS class brings together all those chemicals that present a hazard as a result of their tendency to undergo violent reaction. The chemical reaction can sometimes lead to a fire or an explosion.

42. Consumer ProductsDangerSevere hazard / immediate harmCautionModerate hazard / long-term or hidden harmWarningSpecial hazard / special requirements

43. Consumer ProductsType of Hazardfire hazardwill ignite if exposed to a spark or flame. Store away from heat/use in a ventilated areapotentially fatal if inhaled or swallowedmay have serious long-term health effects. Use gloves and face mask and wash after usehandle container with carewear gloves and may explode if heated or dropped, may react violently with other materialscauses skin / eye burnsdo not breath fumes, wear eye protection and gloves, keep container sealed, may damage metals

45. Consumer Product CategoriesToxic productsCorrosive productsFlammable productsQuick skin bonding adhesivesPressurized containers

47. Employer Responsibility and Worker TrainingUnder the Occupational Health & Safety Act, an employer must take all reasonable precautions to protect the health and safety of workers.

48. Therefore, it is an employer's responsibility to ensure that all workers who have come into contact with these products receive training on how to: Read consumer product labels

49. Recognize consumer product symbols

50. Properly use, handle, store, and dispose of the productsTransportation ofDangerous Goods: TDG• Transportation of Dangerous Goods Act - 1992• Co-operation between federal, provincial, and territorial governments• Legislation to ensure that there is a minimum safety standard which applies to the shipment of hazardous materials throughout Canada.

51. Samples of labels or placards Class 8Corrosive SubstancesShown are some samples of labels or placards that one can find on transport vehicles. Class 5 Oxidizing SubstanceClass 2 Flammable Gas

52. Labelling

53. The label is one of the primary methods to convey info. to people using hazardous substances.Labels are easily identifiable, appear on containers in some fashion, & contain easily understood information about the risks associated with the material inside the container.

54. The label also directs the reader to the MSDS, one of the other main components in information delivery about hazardous materials to users. There are two types of labels required under WHMIS: Supplier labels and Workplace labels

55. In addition, WHMIS provides for the use of identifiers in place of workplace labels in some circumstances. Supplier LabelsThe responsibility for supplier labelsrests with the supplier. Under the HPA, a supplier cannot sell controlled products unless labels are attached to the containers with the prescribed information.

56. Design RequirementsThe label must be English& FrenchHatch marked border must be in a colour that contrasts with the background

57. 7 Required pieces of information needed on a supplier label and are as follows:Name of product (can be chemical name, common name, generic name, or trade name)Labels also must be in both English and French and have a contrasting hatch marked borderName of supplier & reference to the MSDS First aid measures stating immediate steps to take in case of exposure

58. WHMIS / Hazard Symbol(s) as outlined/ referenced in the Classification Section of the manualRisk phrases which state the hazardous properties of the product Precautionary measures which state the precautions you should take when using the product (example: PPE)

59. Workplace LabelsThe responsibility for workplace labelsrests with the employer. Information required on workplace labels is less than the requirement on supplier labels.There are no specific design requirements for workplace labels

60. Workplace LabelsRequired InformationA product identifier

61. Safe handling instructions

62. Statement making reference to the MSDSMaterial Safety Data Sheets

63. MSDSs: Who is Responsible?SupplierCreate MSDS with prescribed information

64. Update every 3 years as needed

65. Provide MSDS in both official languages

66. Ensure MSDSs are completeEmployerCarry out written inventory and assessment of

67. All controlled products being used or

68. Produced in the workplace

69. Obtain current MSDS and keep it updated

70. Ensure MSDSs are available to workersWorkerMust inform supervisor of a missing or incomplete MSDSRequired on MSDS's

71. Information & Training Requirements

72. The employer must train workers who use controlled products the components of WHMIS (MSDS's, labels) in an effective manner so that they can apply the principles in the workplace.Instruction must also be given on the safe handling, use, storage and disposal of a material, and what to do in an emergency.

73. The employer must consult with the Joint OH&S Committee or the Safety Representative on the development, status, and implementation of the program.

74. The employer must review the program at least once a year or more often where new hazard material has become available or other circumstances. The review must include a review of the worker's familiarity with the information conveyed through training and supervision. The WorkerThe worker is required to participate in any of the training programs offered by the employer

75. Principles to Control Hazards

76. Hazard Recognition / Risk Identification

77. Hazard Evaluation / Risk Assessment

78. Hazard Control / Risk ControlOnce hazards have been identified & assessed, they can be:

79. Controlling Hazards At The Source The best point to control hazards is at the source. The further the hazard gets from the source (i.e. to the worker) the more difficult it becomes to control it.

80. Types of ControlsEngineering= ventilation/barriers

81. Administrative= work/rest periods job rotation

82. Work practices = safe handling, training

83. PPE= last line of defence when other options are not practical (can also be temporary use)Controlling Hazards Along The Path

84. Controlling Hazards At The WorkerControlling hazards at the worker should be that last line of defense, used only when other controls are not practical or in conjunction with other controls that are not adequate in themselves. Examples of controls at the worker include: PPE

85. Work Practices
