What does it stand for?
WHMIS Stands for:
•Workplace
•Hazardous
•Materials
•Information
•System
WHMIS – Why?
• WHMIS provides us with information on the safe use, storage, handling and disposal of hazardous materials at Canadian workplaces.
• WHMIS uses symbols to indicate materials that may be harmful to us.
The WHMIS Symbols:
What do all of these symbols mean?
Class A: COMPRESSED GAS
• Chemicals such as oxygen or acetylene that are kept under pressure in a container.
• Hairspray, any aerosol cans
Class B: FLAMMABLE AND COMBUSTIBLE MATERIAL
• Materials and chemicals that will easily ignite.
• Rubbing alcohol, hairspray, propane, butane lighters, bug spray
Class C: OXIDIZING MATERIAL• Chemicals that are usually not
combustible by themselves but they contain oxygen which helps other materials burn.
• Eg. Chlorine for pools, oven cleaner, hydrogen peroxide
Class D1 – POISONOUS or INFECTIOUS MATERIALS
• Will cause immediate poisoning, sickness or death in a short period of time
• Eg. Rat poison, rubbing alcohol
Class D2 – POISONOUS or INFECTIOUS MATERIALS
• Will have long term effects on health• Effects may not show up for years –
poisoning over time. Eg. cancer, emphysema
• Eg. Insecticides, Herbicides, Terpentine
Class D3 – BIOHAZARDOUS INFECTIOUS MATERIAL
• May contain germs or viruses that could infect you and cause disease.
• Eg. waste from a hospital, needles, bandages, vaccines etc.
Class E – CORROSIVE MATERIAL
• Such as acid which may attack metal or skin
• Eg. ammonia, hydrochloric acid, draino
Class F – REACTIVE MATERIAL• May react violently causing explosion or
sudden release of gases. May do so when mixed with other materials.
• Eg. Sodium, epoxy resins (strong glue), acetylene torches (welding)

What is an MSDS?
•Material
•Safety
•Data
•Sheet
When do we use an MSDS?
• Every product that may be hazardous MUST have an MSDS that tells us the dangers of the material and how to safely handle and dispose of it.
What are the parts of an MSDS• An MSDS has 9 sections:
1. Product Identification and Use2. Hazardous Ingredients 3. Physical Data4. Fire and Explosion Data5. Reactivity Data6. Toxicological Properties7. Preventative Measures8. First Aid Measures9. Preparation Date of MSDS
1. Product Identification and Use
• Manufacturer's name
• Supplier's name
Hazardous Ingredients
• List any that are in the product
Physical Data
• Physical Data• Colour• Form• Solubility• Melting and boiling points• Vapour pressure• Specific gravity
Fire and Explosion Data
• Flammability
• Flashpoint
• Fire fighting procedures
Reactivity Data
• Stability and Hazards
Toxicological Properties
• Threshold Limit Values (TLV)
• Effects of exposure
• Carcinogenicity (does it cause cancer?)
Preventative Measures
• Protective clothing
• Protective equipment
• Spill and handling procedures
First Aid Measures
• How to administer first aid if an accident does occur with the product
Preparation Date of MSDS
• When the product was packages and the MSDS was prepared.
