2. OBJECTIVES
After completion of this course, you should be able to
understand:
• How to determine the hazards associated with the product(s) that you
are using?
• How do you protect yourself?
• Where do you go to get more information on this product?
3. INTRODUCTION TO WHMIS
Everyday thousands of workers are exposed to hazardous materials.There
are many severe health problems that come with exposure to hazardous
materials some of which include:
• Burns
• Allergic Reactions
• Sterility
• Lung and Kidney damage
• Cancer
• Heart Attacks.
• Other dangers from hazardous materials can cause fires or explosions.
5. WHAT IS WHMIS?
WHMIS (Workplace Hazardous Material Information System)
has been developed to provide specific health and safety
information on hazardous materials called controlled products.
•WHMIS provides information about many controlled
products used in the workplace with the goal to reduce
injuries and disease by laying out specific health and safety
protocols about controlled products and therefore reducing
exposure to hazardous materials in or around the workplace.
6. WHMIS CLASSIFICATIONS
• The WHMIS system classifies hazards into 6 different
Hazard Classes.
• These hazard classes are depicted by 8 Hazard Symbols.
• Hazard symbols are used to identify the specific hazard
associated with the controlled product.
8. • We are now going to take a closer look at the 6
Classes and 8 symbols. HINT: Pay attention!
9. Class A: Compressed Gas
It is important to know that these containers
cannot be stored or placed near heat or
dropped as this may cause the container to
explode.
Examples of Class A – Compressed Gases would be: Propane, Oxygen and
Acetylene.
10. Class B: Flammable and Combustible Material
Class B is made up of solids, liquids and gases that
are capable of catching on fire by means of spark or
open flame in normal working conditions.
Examples include: Butane, Gasoline or Acetone.
11. Class C: Oxidizing Material
The main hazard with these products is the risk of
fire when they come into contact with flammable
or combustible materials.
Examples include hydrogen peroxide or compressed oxygen.
12. Class D: Poisonous and Infectious Material
• Class D is separated into 3 divisions as follows:
D1: Materials causing immediate and serious toxic effects.
These materials in small amounts can cause
immediate injuries or death to a person.
Examples include: Hydrogen Sulphide or Sodium Cyanide.
13. D-2: Materials causing other toxic effects.
These materials can cause serious long-term
health problems and severe immediate
reactions to the material over long periods of
time when being exposed to small amounts
repeatedly.
14. D-3: Biohazardous Infectious Material
Biohazardous Infectious materials contain dangerous
micro-organisms that can be extremely harmful to
humans.
Examples include hydrogen peroxide or compressed oxygen.
15. Class E: Corrosive Material
Corrosive materials are acids and caustics that can
burn and destroy skin or eat through metals.
Examples Include: Hydrochloric acid or nitric acid.
16. Class F: Dangerously Reactive Material
When exposed to temperature, pressure or shock
these material may explode. They also carry a risk
of self-reacting or releasing poisonous gases when
exposed to water.
Examples Include: Butadiene and some cyanides.
17. WHMIS LABELS
• Another important part of theWHMIS system is the use of labels on
controlled products.
• There are 2 types of labels used in WHMIS
• Supplier Labels
• Workplace Labels
• The purpose of WHMIS labels are to:
• Alert the worker of any hazards with the controlled products.
• Provide safe work procedures.
• Inform the worker of First Aid information.
18. SUPPLIER LABELS
• Any controlled product that is sold or used in the workplace must have a
supplier label attached to the container. It is the supplier who produces or
imports the controlled products that must comply to this WHMIS legislation.
Example of supplier
Label for Methanol
19. WORKPLACE LABELS
It is the responsibility of the employer to supply workplace labels when necessary.
•There are 3 types of information that must be written on
workplace labels:
1.Product identifier.
2.The specific handling requirements and the types of personal protective
equipment (PPE) needed to handle the controlled product.
3.Reference to MSDS.
20. WORKPLACE LABELS
• When does a workplace label have to be used?
• When the controlled product is transferred to a different or secondary
container that does not have a supplier label on it, or the supplier label is no
longer readable or missing.
Example of a
Workplace label for
Acetone.
21. MATERIAL SAFETY DATA SHEETS
• An MSDS provides the following information:
• Emergency and First Aid procedures
• Specific hazard information
• Safe handling procedures
• Detailed information about health, safety, and hazards for each individual controlled
product.
• WHMIS legislation dictates what information needs to be on an MSDS
and has stipulated 9 sections of information required.
22. THE 9 INFORMATION SECTIONS
1. Product Information: Identifies the controlled product, the
manufacturer and the supplier for its intended use. It will also show
the manufacturer and supplier contact information which is important
in case of emergency.
2. Hazardous Ingredients: This section will list the specific chemical
names, percentages and acute toxicity data for the individual
components that make up the controlled product.
23. 3. Physical Data: Displays general information on the physical and
chemical properties such as boiling points and evaporation rates.
4. Fire and Explosion Hazard: Lists the conditions that can make the
controlled product explode or ignite into flames.This section will also
list procedures to follow if the product does explode or catch on fire.
5. Reactivity Data: Lists other substances that should not be mixed
with the controlled product to prevent dangerous reactions.
24. 6. Toxicological Properties: Identifies how the product enters the
body and the health effects from single or repeated exposure. It will
also state known long-term health damage such as kidney, liver, lung,
cancer or reproductive effects.
7. Preventative Measures: Lists what to do if there is a spill of the
controlled product, types of personal protective equipment (PPE) to
use and how to safely store, handle, transport and dispose of the
product.
8. First Aid Measures: If a worker is injured from inhaling, swallowing
or absorption through the skin or eyes from the product, this section
will list specific instructions for immediate treatment.
9. Preparation Information: Announces the date the MSDS were
made and who prepared it.
25. WHERE TO FIND MSDS’S
• Each division manager at BUSU will maintain a binder with all necessary
MSDS for their department and keep it in an accessible location.
• A Master MSDS binder for all controlled products found within BUSU
will be maintained and located at the reception desk.
• MSDSs must be made available to workers on shift at all times.
26. PERSONAL PROTECTIVE EQUIPMENT (PPE)
• Specialized clothing or equipment worn by employees for protection
against health and safety hazards. Personal protective equipment is
designed to protect many parts of the body including eyes, face, hands
and feet.
• Examples of PPE you may be required to
wear in the course of your employment at
BUSU include Aprons, gloves, or safety glasses.
