• WHMIS - Workplace Hazardous
Materials Information System
• Hazard Communication System
• Developed by Canadian Federal,
Provincial and Territorial
Governments
What is WHMIS?
• Prevention
• Reduce Injury and Illness
Goal of WHMIS
• Education
• Labelling
• MSDS
Three Key Components
• Meets any criteria for inclusion in
WHMIS Hazard Classes
• No comprehensive list - just Hazard
Criteria
Controlled Products
• A: Compressed Gases
• B: Flammables and Combustibles
• C: Oxidizing Materials
• D: Poisonous and Infectious
Materials
• E: Corrosive Materials
• F: Dangerously Reactive Materials
Six Classes
Risks/Dangers
• Physical Hazard
• Explosive Hazard
• Content Hazard
CLASS A
http://www.worksafebc.com/publications/health_and_safety/whmis/assets/image/WHMIS2.JPG
• Toxic Gases (Carbon Monoxide,
Hydrogen Cyanide and Phosgene)
• Corrosive Gases (Ammonia, chlorine
and Sulfur Dioxide)
• Flammable Gases (acetylene and
ethylene)
Examples of CLASS A
• Secure Cylinder
• Avoid Heat and Ignition Sources
• Transport and Handle Carefully
• Store in a cool ventilated area
Safety Precautions
Dangers/Risks
• Fire Hazard
• Can spontaneously
ignite
• Potentially poisonous
CLASS B
http://www2.worksafebc.com/i/whmis/Symbols&Labels/SymbolB_sm.gif
• Gas: Hydrogen, Methane
• Liquid: Ether, Ethanol
• C. Liquid: Kerosene
• Solid: Magnesium
• Aerosol: Aerosol Containers
• R. Flammable Materials: Sodium
Examples of CLASS B
• Avoid contact with flames or ignition
sources
• Avoid heat
• Store with cap tightened (vapours
more flammable than liquid)
• Avoid Inhalation and skin contact
Safety Precautions
Dangers/Risks
• Fire and explosion
hazard
• Corrosive and
Poisonous
CLASS C

• Nitrates/ Nitrites
• Chlorates / Chlorites
• Peroxides
• Dichromates
• Permanganates
• Persulfates
Examples of CLASS C
• Protective Clothing - Avoid personal
contact
• Store away from heat and
flammable materials
• Non-corroding Containers
Safety Precautions
• Acute
• Chronic
• Biohazard
CLASS D
http://www.worksafebc.com/publications/health_and_safety/whmis/assets/image/WHMIS1.JPG
Risks
• Lethal at low Dose
• Toxic
Acute
• Examples:
• Halogens
• Cyanides
• Heavy
Metals
Dangers
• Systemic
Damage
• Illness or Death
• Cancer
• Birth Defects
Chronic
• Examples:
• Mercury, Lead
• Formaldehyde

• Cancer
• Disease of
Infection
Biohazard
• Examples:
• Human Blood
• Animal Blood
• Tissue Cultures
Risks and Dangers:
• Will burn human tissue
• Corrode materials
• Environmentally
Damaging
CLASS E
http://www.worksafebc.com/publications/health_and_safety/whmis/pub_40_20_20_10.asp
Examples
• Most Oxidizing Materials
• Strong Acids and Bases
• Hydrogen Fluoride,
Hydrogen Chloride,
Chlorine, Bromine, Sulfur
Dioxide
Examples of CLASS E and Safety
• Safety
• Do not bring near
Human Tissue
• Keep away from
Metals
• Do not allow fumes
to escape
Risks:
• Violent Reaction
• Poisonous Vapors
CLASS F
http://www.worksafebc.com/publications/health_and_safety/whmis/pub_40_20_20_10.asp
• Pitric ACid
• Ether
• Perchloric Acid
• Alkali Cyanides
Examples of CLASS F
• Avoid Use if possible
• Keep away from potential reactions
• Do not mix with other chemicals
Safety Precautions
• Consumer Restricted Products
• Explosives
• Cosmetics, Drugs and Food
• Pest Control Products
• Radioactive Materials
• Wood and products made of Wood
• Tobacco
• Hazardous Wastes
Hazardous Materials Not Covered by WHMIS
• Education
• Labelling
• MSDS
Three Key Components
• All products in a Workplace that fall
under WHMIS must have a label
• Two main types
• Supplier and Workplace
Labels
• Product Identifier• Supplier Identifier• Hazard Symbol(s)• Risks• Precautionary Measures• First Aid Measures• Reference to MSDS
Supplier Label
http://www.qshi.ca/_images/courseImages/Modules/supplier_label.jpg
Reasons for a Workplace Label
• Decanted or transferred
• Original Label Lost
• Products produced and used at Workplace
Workplace Label
• Education
• Labels
• MSDS
Three Key Elements
• Information about controlled product
• Must be provided by supplier
• Illegal to use product without MSDS
• No more than 3 years old
MSDS
Example of MSDS

Components• Chemical Product and Company Information• Composition and Information on Ingredients• Hazards Information• First Aid Measures• Fire and Explosion Data• Accidental Release Measures• Handling and Storage• Exposure Controls• Physical and Chemical Properties• Stability and Reactivity Data• Toxicological Information• Ecological Information• Disposal Considerations• Transport Information• Other Regulatory Information• Other Information
MSDS
• Small Spill• Dilute with water (if necessary sodium carbonate
solution)-mop up-place in appropriate waste disposal
• Large Spill• Absorb with non combustible material-dike if
needed (to prevent entry into sewer/water systems)-Keep Vapours at bay-Call for Help/Assistance
EXTRA-HOW TO CLEAN UP A SPILL EG. Hydrochloric Acid
