Workplace Hazardous Materials
Information System
WHMIS
Update
Safety Is No Accident
Workplace Hazardous Materials
Information System (WHMIS)
• 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
• In effect October 31, 1988
• Applies to hazardous materials known as
controlled products: (Class A, B, C, D, E and F)
WHMIS Regulation, Ontario Reg.
644/88
• Sets out in detail employer duties
respecting
• labels,
• material safety data sheets and,
• worker education
• (all other provinces and territories based their WHMIS on same
model to promote consistency across Canada)
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
Other Exemptions

Wood or wood products

Tobacco or tobacco products

A manufactured article

Restricted products when packaged as
consumer products

Hazardous wastes transported under TDG
Act
Workplace Hazardous Materials Information
System (WHMIS) O.Reg. 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
Responsibilities:
Hazardous, or Controlled 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 (cont’d)
• 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
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
liquified 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
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, indicates how the
substance may enter the body (inhalation, skin absorption,
ingestion), 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 heat, burning sunlight; name of any
substance or class of substance with which the product
is incompatible; decomposition.
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, TLV or TWAEV Time
Weighted Average Exposure Value, Short Term Exposure
Value, 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.
