5 Course OutlineIntroductionWHMISLabelsMaterial Safety Data SheetsWorker EducationWHMIS LegislationSummary
6 Glossary - Common Terms in an MSDS English:French:
7 Introduction to WHMISWHMIS is Canada-wide legislation, dealing with controlled products in the workplace.A controlled product is ‘any product, material or substance included in any one of the classes listed in the Hazardous Products Act (HPA).’NOTE: HPA is federal legislation
8 Hazardous Classes Under HPA Class A: Compressed GasClass B: Flammable and Combustible MaterialClass C: Oxidizing MaterialClass D: Poisonous and Infectious MaterialClass E: Corrosive MaterialClass F: Dangerously Reactive Material
9 WHMIS is Designed to Solve the Problem of:Unlabelled materials in the workplaceInadequate or contradictory information being given to employers/workers regarding identification, hazardous properties and precautions to be taken with hazardous materials used in the workplace
10 Three Components of WHMIS Labels on hazardous materials or their containersMSDS or material safety data sheets which are technical bulletins providing more detailed information than the labelWorker education and training, providing instruction on hazards and safe work procedures
11 Hazardous Products Act (HPA) Supplier Defined“Supplier" means a person who is a manufacturer, processor or packager of a controlled product or a person who, in the course of business, imports or sells controlled products;Hazardous Products Act (HPA)
12 Flow of Information Producer Supplier Importer Supplier label MSDS EmployerJHSCinputWorker TrainingInformed worker
13 LabelsTwo Types:Supplier labels (developed and provided by the supplier)Workplace labels (developed and used in the workplace)
14 Supplier Label: Design and Application Content layout: not legislatedBorder: specificColour: not legislatedLegibility: distinct; good contrastDurability: able to withstand normal useApplication: imprinted; stencilled; attachedLanguage: English and French
15 Supplier Label: Required Statements 1. Product Identifier2. Hazard Symbols3. Risk Phrases4. Precautions5. First Aid6. Supplier Information7. Reference to MSDS
20 What Do We Know?Compressed Gas(Class A):Poses an explosion danger because the gas is under pressureContainer may explode if heated or droppedContainer may become a projectile if the stem is broken off
24 Combustible and Flammable Material (Class B): What Do We Know?Combustible and Flammable Material(Class B):Will burn and is therefore a potential fire hazardMay burn at relatively low temperatures; flammable materials catch fire at lower temperatures than combustible materialsMay burst into flame spontaneously in air, or release a flammable gas on contact with waterMay cause a fire when exposed to heat, sparks, or flames, or as a result of friction
25 ExamplesCombustible and Flammable Material(Class B):Flammable:Butane, propane, hydrogen gas, acetone, gasoline, isopropyl alcohol, magnesium alloys, etc.Combustible:Kerosene, diesel, mineral spirits, varnish, etc.
26 Flammable Vapours + Spark = Fire Vapors + Spark = Fire. Most people know that. The owner of this truck, a retired tech sergeant, knew it too. But (there's always a but), he still received third-degree burns after static electricity ignited gasoline as he filled gas cans in the bed of his pickup truck. How could this happen, you ask? Well, y'see the thing about static electricity is, some environments are more spark-worthy than others. You know, like when you walk on carpet in socks, or rub a balloon on your frizzy hair, or when you get out of your car (especially in the winter-time). If you're going to be around combustible material ... think! Have you grounded yourself? Are you doing something somewhere that might cause a spark or fire? Our TSgt (ret.) should have been filling his gas cans on the ground. Proof that the laws of nature still work. And remember ... just 'cause it doesn't happen often doesn't mean it can't happen to you.
29 What Do We Know?Oxidizing Material (Class C):Poses a fire and/or explosion risk in the presence of flammable or combustible materialMay react violently when it comes into contact with combustible materials such as fuels or woodMay burn skin and eyes upon contact
30 ExamplesOxidizing Material (Class C):Examples:Perchloric acidHydrogen peroxideNitric acidCompressed oxygenOzone
33 What Do We Know?Poisonous and Infectious Material(Class D, Division 1):Is a potentially fatal poisonous substanceMay be fatal or cause permanent damage if it is inhaled or swallowed or if it enters the body through skin contactMay burn eyes or skin upon contact
36 What Do We Know?Poisonous and Infectious Material:Other Toxic Effects (Class D, Division 2):Not immediately dangerous to healthMay cause death or permanent damage as a result of repeated exposure over timeMay be a sensitizer, which produces allergic reactionsMay cause cancers, birth defects, or sterility
39 What Do We Know?Poisonous and Infectious Material: Biohazardous, infectious material(Class D, Division 3):May cause a serious disease resulting in illness (AIDS, Hepatitis) or deathCan also include tetanus protection
40 ExamplesPoisonous and Infectious Material: Biohazardous, infectious material(Class D, Division 3):Examples:Salmonella bacteriaHepatitis B virusHIV-AIDSParasitesBodily fluids, such as blood and urine
42 What do We Know?Corrosive Material (Class E):Causes severe eye and skin irritation upon contactCauses severe tissue damage with prolonged contactOften produces vapour or fumes that may be harmful if inhaled
45 What Do We Know?Dangerously Reactive Material(Class F):Is very unstableMay react with water to release a toxic or flammable gasMay explode as a result of shock, friction or an increase in temperatureMay explode if heated when in a closed containerUndergoes vigorous polymerization
48 Workplace LabelsMethanolAvoid inhaling vapours, handle with careFlammableAvoid eye and skin contactSee MSDS for more informationProduct IdentifierInformation on safe handling of the productReference to MSDS
49 Workplace LabelsMust be displayed to give clear warning to employeesMay be a label, tag, sign or otherIs not required to be bilingual; can be in the language of the workplace
50 Quiz A: True or False?1. Labelled products, MSDSs and worker education can help lower the risk of accidents.2. WHMIS is a hazard class driven system.(name the classes)3. A WHMIS supplier label can be identified by its solid red border.4. A supplier label must list precautions and first aid instructions.5. All workplace labels present in New Brunswick workplaces must be in both English and French.
51 Material Safety Data Sheets The MSDS is:- A technical information reference for worker education, control measures and emergency responseA document that can be distributedA document that must be available to workers
52 Material Safety Data Sheets The MSDS is NOT:- All the information needed for the safe use of a product in every possible situation- A document only to be read and filed
53 MSDS Required Criteria 1. Product Identifier2. Ingredients3. Physical Data4. Fire and Explosion Hazards5. Reactivity Data6. Toxicological Properties7. Preventive Measures8. First Aid Measures9. Preparation Information
54 Section 1: Product Identification and Use The intent of this section is for product identification, supplier identification, and a description of the product useIt is of particular use in organizing data sheets for quick retrievalIt includes the emergency telephone number
55 Section 2: Hazardous Ingredients This section provides information on the identity, concentration, and estimators of acute toxicity for the ingredients of a controlled productCopyright law permits limiting information in this section however, disclosure is mandatory if a worker is exposed to the productUseful information for emergency health care providers
56 Lethal Dose and Lethal Concentration The lower the lethal dose and lethal concentration numbers, the more dangerous the material is to human beings.LD50 / LC50
57 Section 3: Physical Data This section provides a physical description of the productIt describes its response to changes in the physical environment, and has specific applications for ventilation system design and emergency procedures
58 Section 4: Fire or Explosion Hazard The intent of Section 4 is to provide information to assist with fire and explosion prevention, as well as emergency procedures.This section is particularly important with flammables, solvents, organic peroxides, explosives, metal dusts and other unstable substances. If the product is not flammable or explosive, information in this section must reflect that fact.
59 Section 5: Reactivity Data Information on the stability of the product and its likelihood of dangerous reaction with other chemicalsImplications for handling procedures and storage arrangementsMay be useful along with Section 4 data for the prevention and control of fires or explosions
60 Section 6: Toxicological Properties This section provides information on how a material is likely to enter the body and what short and long-term effects it is likely to haveIncludes signs and symptoms of exposure and pre-existing medical conditions which may be aggravatedInformation in this section is an important determinant of preventive and first aid measures and emergency care
61 Section 7: Preventive Measures Provides clear direction for transportation, storage, use and disposal of the product, as well as emergency procedures related to accidental releaseInformation must be as specific as possible. Employers may need to adapt information from data sheets to the specific hazard circumstances of each workplace
62 Section 8: First Aid Measures Information necessary for the safe evacuation and immediate treatment of a person experiencing acute effects of overexposureMeant for use by workers on site, including first aid personnelUsually expands on the first aid instructions described on the supplier label
63 Section 9: Preparation Information Name and telephone number of those responsible for MSDS preparationDate of preparationWHMIS legislation requires that MSDS be kept current; no older than 3 years
64 General Approach to MSDS Identify the chemical and the emergency telephone numberKnow the hazards/precautionsUnderstand safe handling and storage proceduresEmergency procedures (in case of an emergency bring the MSDS with you to the hospital)Identify the preparation date
65 Quiz B: True or False?1. An MSDS contains the same information that is present on the supplier label.2. An MSDS has all the information for every possible situation and workplace.3. An MSDS can be used to determine safe storage requirements and emergency procedures.4. An MSDS does not include the emergency telephone number of the manufacturer or supplier.5. MSDSs must be stored together and indexed for easy access.
67 Worker Training and Education 6(3) An employer shall ensure, so far as is reasonably practicable, that the program of employee instruction and training required by subsection (1) results in an employee being able to apply the information as needed to protect the employee’s health and safety.
68 Worker Training and Education Anyone working with or near controlled products must be trained in hazard information and procedures regarding:Safe useStorageHandlingDisposalEmergency procedures
69 Worker Training and Education Includes information found on labels (supplier and workplace), MSDS and any information of which the employer is aware*The training should be:Relevant to the workplacePerformance orientedDeveloped in consultation with the JHSCReviewed at least annuallyModified as conditions change
70 Quiz C: True or False?1. Employers must train workers who work with or near hazardous materials.2. All employees should receive WHMIS training whether or not they are working with controlled substances.3. Employees do not need to know emergency procedures regarding hazardous materials.4. Employees need to be given information for controlled products flowing through pipes in the workplace.5. An employee’s knowledge of the product can affect the amount of damage or injury in an emergency.
71 Exceptions to the rule… Eight classifications exempt from WHMIS labelling and MSDS requirements. Some categories are regulated for worker education, some are not.1. Explosives 5. Consumer products2. Cosmetics, drugs,food 6. Wood products3. Pesticides Tobacco products4. Radioactive materials 8. Manufactured articles
72 Exceptions to the rule… Exceptions are usually covered under other Legislation (example, Pesticides Control Act).Products brought into the workplace that are not designed for commercial or industrial use (consumer products) are still controlled products under the HPA (MSDS and workplace labels may be required).
73 WHMIS Responsibilities Suppliers, employers and employees each have a role to play in making WHMIS work!
74 Supplier Responsibilities Supplier responsibilities are found under the Hazardous Products Act (Federal Bill C-07) and the Occupational Health & Safety Act, Section 13Suppliers Must:I. Label controlled products intended for workplace useII. Supply MSDS with each controlled product
75 Employer Responsibilities The employer’s WHMIS responsibilities are outlined in Provincial Regulation :To obtain MSDS from supplierEnsure appropriate labelling (supplier and workplace)Provide adequate instruction and training to employeesSort and file the MSDS in a clearly indicated and easily accessible area
76 Employee Responsibilities WHMIS legislation does not place any direct responsibility on the workers, however under Section 12 of the OHS Act, employees must:Comply with the ActConduct themselves to ensure their health and safetyReport hazardsWear/use protective equipmentConsult/co-operate with the JHSC
77 Quiz D: True or False?1. The workplace copy of the MSDS needs to be updated every three years, even if there has been no change in the hazard information.2. The employer shall review their WHMIS system (employee training and MSDS) at least once a year.3. Pesticides are exempt from MSDS and label requirements, therefore worker training isn’t necessary.4. Telling workers to read the labels and the MSDS is adequate training.5. Employees don’t have to watch out for their own safety; it’s the boss’s responsibility.
78 Developing WHMIS for your workplace Step 1:Assign responsibilityInventory and list supplier and workplace labelsStep 2:Get current MSDSDetermine storage, handling, training, first aid and disposalStep 3:Train employeesImplement control measures and MSDS binders
