Workplace Hazardous MaterialsInformation System



Workplace hazardous materials information system whmis
Workplace Hazardous Materials Information System (WHMIS)

  • WHMIS became legislated in October 31, 1988

  • Developed jointly by labour, industry, federal, provincial and territorial governments

  • A Canada-wide system designed to give employers and workers information about hazardous materials in the workplace

  • Applies to hazardous materials known as controlled products: (Class A, B, C, D, E and F)

Workplace hazardous materials information system whmis ontario regulation 860
Workplace Hazardous Materials Information System (WHMIS) Ontario Regulation 860


  • To provide information on hazardous materials used in the workplace

  • To facilitate the process of hazard identification in the workplace

  • To ensure consistency of hazard information in all Canadian workplaces

Exemptions from whmis
Exemptions from WHMIS Ontario Regulation 860

The provincial WHMIS legislation does not apply to federal workplaces such as banks, post offices and airports. Canada Labour Code and Canada Occupational Safety and Health Regulations implement WHMIS in federal workplaces.

Products under the Federal Acts:

  • Pest Control Products Act

  • Food and Drugs Act

  • Canadian Nuclear Safety Commissions Act

  • Explosives Act

Responsibilities regarding hazardous materials
Responsibilities Regarding Ontario Regulation 860Hazardous Materials


  • Workplace inventory (in consultation with JHSC)

  • Assessment on Designated Substances

  • Workplace labels

  • Material Safety Data Sheets (MSDS)

  • Worker education (in consultation with JHSC)

Responsibilities hazardous materials
Responsibilities: Hazardous Materials Ontario Regulation 860


  • Participate in Training

  • Apply knowledge

  • Recognize and report hazards to the supervisor

3 main components of whmis
3 Main Components of WHMIS Ontario Regulation 860

  • Labeling Requirements

    • Supplier WHMIS label

    • Workplace Label

  • MSDS

    • Material Safety Data Sheets

    • Employer

    • Worker

Whmis hazardous symbols
WHMIS Hazardous Symbols Ontario Regulation 860

Class A

Compressed Gas

  • Any material which is a gas at normal temperature (20 degrees) and pressure, but is packaged as pressurized gas, dissolved gas or gas liquefied by compression or refrigeration. E.g. oxygen, chlorine, acetylene, etc

Symbols Ontario Regulation 860

Class B

Flammable & Combustible Material

  • Will ignite and continued to burn in air if exposed to a source of ignition.

  • Gas, aerosol, liquid, solid

  • E.g. methane, acetone, etc.

Symbols Ontario Regulation 860

Class C

Oxidizing Material

  • May or may not burn but will release oxygen contributing to the combustion of other material

  • E.g. ozone, chlorine, nitrogen dioxide, etc.

Symbols Ontario Regulation 860

Class D Poisonous & Infectious Material

  • Materials Causing Immediate

    Serious Toxic Effects

    E.g. styrene, hydrogen cyanide

  • Materials Causing Other Toxic

    Effects (carcinogen, irritant,

    sensitizer) E.g. ammonia, asbestos

  • Bio-hazardous Infectious Materiala biohazard can be either a living organism or the chemical toxin that it produces that

    cause disease in humans

    E.g. Hepatits B

Symbols Ontario Regulation 860

Class E

Corrosive Material

  • Can attack metals or cause permanent damage to human tissues

  • May weaken structural containers

  • E.g. ammonia, fluorine

    Class F

    Dangerously Reactive Material

  • May react violently under conditions of shock or increases in temperature or pressure

  • May react with water to create toxic gas

  • E.g. ozone, benzoyl peroxide, vinyl chloride, picric acid and ethylene oxide

Supplier labels
Supplier Labels Ontario Regulation 860

Eight (8) pieces of information in English & French:

a. Product Identifier (common/chemical name)

b. Hazard Symbol(s)

c. Risk Phrase(s)

d. First Aid Measures

e. Supplier Identifier (name, address, etc.)

f. Reference to MSDS

g. Precautionary Measures

h. Border – must be distinctive & different from background of container

Nine or more categories of information: (MSDS handout)

Product Identification and Use

The product identifier, use, manufacturer’s name, address, and the PIN number (product identification number).

Hazardous Ingredients

CAS or chemical abstract services, LD50 is lethal dosage which is commonly used for solids and liquids and is the weight of a substance which, if given all at once, is expected to cause the death of 50% of a test animal population, LC50 is lethal concentration, refers to the quantity of gases or vapours and is the concentration of a substance in air which administered over a specified period, is expected to cause the death of 50% of a test animal population.

Msds cont d
MSDS Ontario Regulation 860(cont’d)

Physical Data

State of the product - gas, solid, liquid, the appearance, colour, odour threshold, vapour pressure, vapour density, evaporation rate, boiling point, freezing point pH, specific gravity, coefficient of water/oil distribution.

Fire and Explosion Data

Conditions under which material may be flammable (ignite and burn readily), means of extinction, explosion data (explode as a result of being dropped or subjected to impact), sensitivity to static discharge, safe handling methods, flash point, auto ignition temperature, Upper Explosive Limit/Lower Explosive Limit.

Msds cont d1
MSDS Ontario Regulation 860(cont’d)

Reactivity Data

Conditions under which the product is chemically unstable such as heating, burning, exposure to sunlight, will list the substance or class of substance with which the product is incompatible, or decomposition products.

Msds cont d2
MSDS Ontario Regulation 860(cont’d)

Toxic Properties

Explains the health effects which may result from over exposure, route of entry into the body, inhalation, absorption, ingestion, puncture/injection, acute or chronic, occupational exposure limits like TWA Time Weighted Average Values, Short Term Exposure Limits, Ceiling, evidence of carcinogen, sensitizing capabilities.

Preventative Measures

How to avoid potential hazards associated with exposure to the material, - controls, equipment and procedures (i.e. type of eye protection/hand/face), waste disposal, handling and storage procedures, shipping information.
