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.
