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
Purpose 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
![Page 4: Workplace Hazardous Materials Information System](https://reader036.vdocuments.us/reader036/viewer/2022062314/56814214550346895dae21d9/html5/thumbnails/4.jpg)
Exemptions from WHMIS
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

WHMIS Hazardous SymbolsClass 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
![Page 9: Workplace Hazardous Materials Information System](https://reader036.vdocuments.us/reader036/viewer/2022062314/56814214550346895dae21d9/html5/thumbnails/9.jpg)
Symbols
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.
![Page 10: Workplace Hazardous Materials Information System](https://reader036.vdocuments.us/reader036/viewer/2022062314/56814214550346895dae21d9/html5/thumbnails/10.jpg)
SymbolsClass 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.
![Page 11: Workplace Hazardous Materials Information System](https://reader036.vdocuments.us/reader036/viewer/2022062314/56814214550346895dae21d9/html5/thumbnails/11.jpg)
SymbolsClass 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 Material a biohazard can be either a living organism or the chemical toxin that it produces that
cause disease in humans E.g. Hepatits B
![Page 12: Workplace Hazardous Materials Information System](https://reader036.vdocuments.us/reader036/viewer/2022062314/56814214550346895dae21d9/html5/thumbnails/12.jpg)
SymbolsClass E
Corrosive Material • Can attack metals or cause permanent
damage to human tissues• May weaken structural containers• E.g. ammonia, fluorine
Class FDangerously 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

MATERIAL SAFETY DATA SHEET (MSDS)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.
