Introduction to WHMIS
WHMIS 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
Hazardous Classes Under HPA
Class A: Compressed Gas
Class B: Flammable and Combustible Material
Class C: Oxidizing Material
Class D: Poisonous and Infectious Material
Class E: Corrosive Material
Class F: Dangerously Reactive Material
WHMIS is Designed to Solve
the Problem of:
Unlabelled materials in the workplace
Inadequate or contradictory information
being given to employers/workers regarding
identification, hazardous properties and
precautions to be taken with hazardous
materials used in the workplace
Three Components of WHMIS
1. Labels on hazardous materials or their
containers
2. MSDS or material safety data sheets
which are technical bulletins providing
more detailed information than the label
3. Worker education and training, providing
instruction on hazards and safe work
procedures
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;

What Do We Know?
Combustible and Flammable Material
(Class B):
Will burn and is therefore a potential fire
hazard
May burn at relatively low temperatures;
flammable materials catch fire at lower
temperatures than combustible materials
May burst into flame spontaneously in air, or
release a flammable gas on contact with water
May cause a fire when exposed to heat,
sparks, or flames, or as a result of friction
Examples
Combustible and Flammable Material
(Class B):
Flammable:
Butane, propane, hydrogen gas, acetone,
gasoline, isopropyl alcohol, magnesium
alloys, etc.
Combustible:

Material Safety Data Sheets
The MSDS is:
- A technical information reference for
worker education, control measures
and emergency response
- A document that can be distributed
- A document that must be available to
workers
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

Section 3: Physical Data
This section provides a physical
description of the product
It describes its response to changes in the
physical environment, and has specific
applications for ventilation system design
and emergency procedures
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.
Section 5: Reactivity Data
Information on the stability of the product
and its likelihood of dangerous reaction with
other chemicals

determinant of preventive and first aid
measures and emergency care
Section 7: Preventive Measures
Provides clear direction for transportation,
storage, use and disposal of the product, as
well as emergency procedures related to
accidental release
Information must be as specific as
possible. Employers may need to adapt
information from data sheets to the specific
hazard circumstances of each workplace
Section 8: First Aid Measures

not designed for commercial or industrial use
(consumer products) are still controlled
products under the HPA (MSDS and workplace
labels may be required).
WHMIS Responsibilities
Suppliers, employers and
employees each have a role to
play in making WHMIS work!
Supplier Responsibilities
Supplier responsibilities are found under the
Hazardous Products Act (Federal Bill C-07) and
the Occupational Health & Safety Act, Section
13
Suppliers Must:
I. Label controlled products intended for
workplace use
II. Supply MSDS with each controlled product
Employer Responsibilities
The employer’s WHMIS responsibilities are
outlined in Provincial Regulation 88-221:
To obtain MSDS from supplier
Ensure appropriate labelling (supplier and
workplace)
Provide adequate instruction and training to
employees
Sort and file the MSDS in a clearly indicated
and easily accessible area
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 Act
Conduct themselves to ensure their health
and safety
Report hazards
Wear/use protective equipment
Consult/co-operate with the JHSC
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.
Developing WHMIS for your workplace
Step 1:
Assign responsibility
Inventory and list supplier and workplace labels
Step 2:
