Records of completion must be uploaded into the IEC database. Completion and documentation of this WHMIS 2015 (GHS) SUPPLEMENT will ensure that workers training is up-to-date and that employers are compliant with the standards in Canada s Hazardous Products Act (HPA), and the new Hazardous Products Regulations (HPR). 1. WHMIS provides information to workers about hazardous materials through which of the following method(s)? a) Supplier & Workplace labels b) Safety Data Sheets c) Worker education & training d) All of the above RATIONALE: WHMIS is a Canada-wide system that provides workers with information about hazardous materials through supplier and workplace labels, SDSs, and worker education and training.

2 In Canada, if a workplace uses hazardous products, there must be a WHMIS program in place. Workers must be educated and trained so they understand the hazards, and know how to work safely with hazardous products. 2. Which of the following are potential effects of a health hazard? Select all that apply. a) Explosive b) Aspiration Hazard c) Respiratory or Skin Sensitization d) Flammable e) Carcinogenicity RATIONALE: Hazard classes are a way of grouping together products that have similar properties. Health Hazards are based on the ability of the product to cause a health effect - such as eye irritation, respiratory sensitization (may cause allergy or asthma symptoms or breathing difficulties if inhaled), or carcinogenicity (may cause cancer). Physical Hazards are based on the physical or chemical properties of the product - such as flammability, reactivity, or corrosivity to metals.

3 3. A simple asphyxiant hazard is defined as: a) A finely divided solid material that can catch fire or explode b) A substance or mixture that displaces oxygen in the atmosphere c) A gas that spontaneously ignites in the air d) A substance or chemical that poses acute toxicity RATIONALE: Simple Asphyxiants are a physical hazard. These products are gases that may displace oxygen in air and cause rapid suffocation. Examples include carbon dioxide, hydrogen, and nitrogen.

A pyrophoric gas: a) Causes oxygen deprivation b) Causes skin corrosion or irritation c) Spontaneously ignites in air at or below 130 degrees Fahrenheit d) Emit flammable substance when in contact with water RATIONALE: Pyrophoric gases, solids, and liquids are all products that catch fire very quickly (spontaneously) if exposed to air.

4 Pyrophoric gases, such as silane, are typically stored in compressed gas cylinders. 5. Match the WHMIS 2015 hazard pictogram with the correct category below: A B C D E F G H I D Flammables (gases, aerosols, liquids, solids); Pyrophoric (liquids, solids, gases); Self-reactive substances and mixtures; Self-heating substances and mixtures; Substances and mixtures which, in contact with water, emit flammable gases, organic peroxides E Oxidizing (liquids, solids, gases) G Gases under pressure C Carcinogenicity; Germ cell mutagenicity; respiratory sensitization; reproductive toxicity; Specific target organ toxicity single exposure; Specific target organ toxicity repeated exposure; Aspiration hazard H Corrosive to metals; Skin corrosion; Serious eye damage F Self-reactive substances and mixtures, Organic peroxides B Acute toxicity (oral, dermal, inhalation.)

5 Fatal or toxic) I Acute toxicity (harmful); Skin irritation; Eye irritation; Skin sensitization; Specific target organ toxicity single exposure (respiratory irritation or drowsiness or dizziness) A Biohazardous infectious materials W HM IS 2 015 ( GH S) TE ST A NSW ERS INDUSTRIAL EDUCATIONAL CO-OPERATIVE 1489 London Road, Sarnia, ON N7S1P6 Ph. 519-383-1222 Fax 519-383-1305 RATIONALE: Pictograms are graphic images that immediately show the user of a hazardous product what type of hazard is present. With a quick glance, you can see, for example, that the product is flammable, or if it might be a health hazard. Pictograms will be on the product supplier labels of the hazardous products you work with. They will also be on the SDSs (as the symbol or words that describe the symbol). 6. A signal word on a shipping label: a) Describes the nature of the hazards of the product b) Alerts the reader quickly to the severity of the chemical s hazard c) Explains how to handle the chemical safely d) Is always accompanied with a pictogram RATIONALE: A signal word is a prompt that alerts you about the degree or level of hazard of the product.

6 There are only two signal words used: "Danger" or "Warning". "Danger" is used for high risk hazards, while "Warning" is used for less severe hazards. Some hazard classes or categories do not have a signal word assigned to them. 7. Workplace labels are required when: a) Products are transferred from its original supplier container into another container b) The supplier label is missing or illegible c) The product is produced in the workplace d) All of the above RATIONALE: Labelling is a key element of the WHMIS standard. Almost all controlled products at any workplace will have a label on it. All labels must meet WHMIS standards, be clear, easy to read, and prominently displayed. 8. A Safety Data Sheet (SDS) is available in the workplace to: a) Assist the purchasing department in buying chemicals b) Describe workplace policy c) Provide detailed hazard and safety information about a controlled product d) None of the above RATIONALE: Safety Data Sheets (SDSs) are a worker s Right-To-Know and provide detailed information about the hazards of a product and how to use it safely.

7 9. Which of the following SDS sections describes emergency procedures, protective equipment and how to contain and cleanup a spill or release? a) First Aid Measures b) Accidental Release Measures c) Handling and Storage d) Exposure Controls/Personal Protection RATIONALE: Every product that is classified as a hazardous product under WHMIS that is intended for use, handling or storage in a workplace in Canada must have an SDS. Section 6, Accidental Release Measures , lists personal precautions, protective equipment, emergency procedures, and proper methods of containment and cleanup.

If you are working with a chemical and need to find out about the routes of exposure, as well as the short and long term effects of exposure, where on the SDS would you look?

8 A) Section 2: Hazard Identification b) Section 8: Exposure Controls / Personal Protection c) Section 11: Toxicological Information d) Section 16: Other Information RATIONALE: Section 11, Toxicological Effects , provides concise but complete descriptions of the various toxic health effects and the data used to identify those effects, including: Information on the likely routes of exposure (inhalation, ingestion, skin and eye contact) Symptoms related to the physical, chemical and toxicological characteristics Delayed and immediate effects, and chronic effects from short-term and long-term exposure Numerical measures of toxicity
