Hazardous Products.
Pg. 4
Ontario Legislation
•Details begin next page...
Pg. 4
All Workers Have a
“Right to Know”
• Where are these hazardous substances
located ?
• How could these hazardous substances
harm me ?
• How could they get into my body ?
• How do I protect myself from this
potential harm ?
Responsibilities Under
WHMIS
• Duties of the Supplier of the Material
to the Employer
– Classify Product
– Apply Supplier Label
– Provide Material Safety Data Sheet.
Pg. 4
Responsibilities Under
WHMIS
• Duties of the Employer
– Maintain a Workplace Inventory of Hazardous
Substances on site
– Ensure Proper Labeling is Used on all WHMIS
Regulated Products
– Label Piping Systems/Vessels (an example
would be a refrigerant pipe in the arena for
making ice)
– Maintain and Make Available Material Safety
Data Sheets (MSDS)
Pg. 4
– Train Workers.
Responsibilities Under
WHMIS
• Duties of a Worker
– Participate in Training
– Apply Knowledge and Training.
Pg. 5
Responsibilities Under
WHMIS
• Duties of the Joint Health & Safety
Committee
– Annually Review the WHMIS System to
ensure that it meets the needs of the
organization.
Pg. 5
Information Delivery
Communication of WHMIS is Achieved By:
• Labels
– Supplier Label
– Workplace Label
• Material Safety Data Sheets (MSDS)
• Worker Education.
Pg. 5
Routes of Entry
How Controlled Substances Enter Your Body
• Inhalation or breathing through your
nose and mouth
• Ingestion or swallowing through your
mouth and into your stomach
• Absorption or soaking in through your
eyes and skin
Pg. 5
• Injection by syringe or other blood or
body fluid exposure.
Physical Forms of
Hazardous Materials
include...
• Dusts
• Mists
• Fumes
• Vapours
• Gases.
Pg. 6
Action of Toxins
Definition: Toxin is a word meaning “Poison”
• Acute Effects – symptoms occur in the short term
• Chronic Effects – symptoms occur on the long term
• Latency Period of Disease - time for disease to
manifest or symptom to appear
• Sensitizers - where you become sensitive to a
hazardous material over a period of time from your
frequency or duration of exposure.
Pg. 6
Dose-Response
Relationship
• Effect is Directly Related to Dose
• Think about anything you are exposed to –
too much sunlight can result in skin cancer,
too much alcohol can result in liver disease
or too much exposure to a hazardous
substance could cause cancer, central
nervous system damage, or possibly a
simple skin rash.

– Any Hazardous Material that is contained
under pressure including compressed gas,
dissolved gas, or liquefied gas.
Pg. 6
Compressed Gas Cylinders
• store and transport with
safety cap
• comply with storage
restrictions
• DO NOT store fuel gas with
oxygen
• secure in an upright position
• use in a well ventilated area
• use the proper type of
regulator and know its
history.
Pg. 7
Not Properly Secured
Class B
• Flammable and Combustible Material
– Flammable Gases
– Flammable and Combustible Liquids
– Flammable Solids
– Flammable Aerosols
– Reactive Flammable Material.
Pg. 7
Flammable Materials
Some products are more
flammable than others and require
special consideration Products
like:
• Methanol, Toluene, Butane,
Ethanol
• Store liquids in Flammable Storage
Cabinet
• NEVER store with oxidizers
• Keep away from heat, ignition
sources, and direct sunlight
• Use static lines when transferring.
Pg. 7
Illustration kindly Provided by the IAPA
Class C
• Oxidizing Material
– Any Hazardous Material which causes or
contributes to the combustion of another
material by giving oxygen or some other
oxidizing substance, whether or not it is
combustible. A common oxidizer would be
where adding oxygen to acetylene with spark
can now cut or melt steel = Cutting Torch.
Pg. 7
Class D1
• Poisonous & Infectious Materials
– Material causing immediate and
serious toxic effects
– Materials which are potentially fatal or
may cause permanent damage if
inhaled, swallowed, or absorbed
through the skin, or may burn the skin
or eyes upon contact
Pg. 7
– A very common symbol that you will
find marking many cleaners and
solvents.
Class D2
• Poisonous & Infectious Materials
– Material causing other chronic or long term
effects
– Material which may cause death or
permanent damage as a result of repeated
exposure over an extended period of time;
may be an irritant to the skin, eyes, or
respiratory system; may cause cancer, birth
defects, or sterility
Pg. 8
– This symbol is often seen marking many
different aerosols – many which may smell
nice, but could cause harm if you don’t follow
the directions.
Class D3
• Poisonous & Infectious Materials
– Biohazardous and Infectious Materials
– Materials which may cause disease in
humans and animals, such as viruses,
bacteria, and fungi; may also include
cultures and diagnostic specimens such as
blood, urine, and body tissue
Pg. 8
– This symbol is seen much more commonly
due to global health issues such as SARS or
West Nile Disease and various STD’s.
Class E
• Corrosive Material
– Material which may corrode aluminum, steel
or human flesh
– Material which are anhydrous corrosive
gases
– You are likely to see this on batteries or very
harsh cleaners.
Pg. 8
Class F
• Dangerously Reactive Material
– Materials which undergo vigorous
polymerization, decomposition, or
condensation
– Materials which become self-reactive under
conditions of shock, or increased temperature
or pressure
– Materials which react vigorously with water to
produce a very toxic gas
Pg. 8
– Common Bleach can be dangerously reactive
when mixed with Toilet Bowl Cleaner.
WHMIS Labels
Supplier Label
• Border
• Product Identifier
• Risk Phrases and Precautions
• Safe Handling Precautions
• Hazard Symbols
• Reference to MSDS
• First Aid
• Supplier Information.
Pg. 9
Workplace Label
• Product Identifier
• Safe Handling Precautions
• Reference to MSDS.
Pg. 9
Workplace Label Uses
Required When:
• Transfer of material from a Supplier Labeled
container to another container
• Replacement of a damaged Supplier Label
A Workplace Label clearly isn’t as detailed or helpful as a
Supplier label and is not used a lot in the workplace, but
sometimes it makes more sense to use one, such as on an oil
dispensing can, as a supplier label would be too large for the
container to be of any value.

should never come in contact with this one
• Conditions of Reactivity – Cold/Hot, Wet/Dry – what
makes it react
• Hazardous Decomposition Products – What’s left
after a reaction and how do I dispose of it.
Pg. 11
Toxicological Properties
Lists information on...
• Routes of Entry – how this product can enter your body
• Exposure Limits – Ontario law on how much of a
hazardous substance you can be exposed to in an 8 hour
period, a 40 hour week or over a 15 minute period
• Synergistic Products – Other products that when mixed
with this one might cause worse harm to you
• Sensitivity to Product – how common is it that people are
affected by being exposed to the product for a long time

suffering a reaction such as a skin rash
• Effects of Acute Exposure – What you might
expect to happen immediately from a single time
exposure
• Evidence of Carcinogenicity, Reproductive Toxicity,
Teratogenicity or Mutagenicity – this is important
because it is all damage that can happen in your
internal body or possibly to your DNA. It could also
occur to a fetus in the fist trimester of pregnancy
(teratogen) – all because you did not follow the
preventative measures.
