WHMIS
Update
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
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
Food
Control Products Act
and Drugs Act
Canadian
Nuclear Safety Commissions Act
Explosives
Act
Responsibilities Regarding
Hazardous Materials
Employer

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
Worker
 Participate in Training
 Apply knowledge
 Recognize and report hazards to
the supervisor
3 Main Components of WHMIS
 Labeling Requirements
 Supplier
WHMIS label
 Workplace Label
 MSDS
 Material
Safety Data Sheets
 Training
 Employer
 Worker
WHMIS Hazardous Symbols
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
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
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
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 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
Symbols
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
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
Supplier Label
Workplace Labels
Available in Scientific Store in ABB – No Charge

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.
MSDS (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’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’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.
MSDS (cont’d.)
First Aid Measures
Provides information on safe evacuation procedures and the
immediate treatment of persons overexposed to the material.
Preparation Data of MSDS
Who prepared the MSDS, telephone number and date of
MSDS. MSDS remain valid for 3 years from the date shown,
unless new information becomes available before then, at
which point the supplier must update the MSDS within 90 days.
