Purpose of WHMIS
• To keep all Canadian workers safe in the workplace…
Responsibilities Under WHMIS
• Duties of the Supplier– Classify Product– Apply Supplier Label– Provide Material Safety Data Sheet
(MSDS)
Responsibilities Under WHMIS
• Duties of the Employer– Conduct Workplace Inventory– Ensure Proper Labeling is Used– Maintain and Make Available MSDS’s– Train Workers
Responsibilities Under WHMIS
• Duties of a Worker– Participate in Training– Apply Knowledge and Training– KEEP YOURSELF SAFE!!
“Right to Know”
• Workers have Access to Information through their Employer
• Don’t be a “yes” employee…
Supplier Label
• Product Identifier
• Hazard Symbols
• Risk Phrases and Precautions
• First Aid, Supplier Information
• Precautions
• Safe Handling Precautions
• Reference to MSDS
What has a WHMIS label?
• Only materials that are deemed hazardous and are found in the workplace require WHMIS labels
• Your nail polish remover, bathroom cleaner, etc. at home are covered separately
WHMIS Hazard Classifications
• Compressed Gas– Any Hazardous Material that is
contained under pressure including compressed gas, dissolved gas, or liquefied gas
Compressed Gas Cylinders
• store and transport with safety cap, because…
• comply with storage restrictions, because…
• DO NOT store fuel gas with oxygen, because…
• secure in an upright position, because…
• use in a well ventilated area, because…
• use the proper type of regulator and know its history, because…

• Flammable and Combustible Material– Any material which can catch fire or
combust when placed near another material
– Includes solids, liquids and gases
Flammable Materials
• Store liquids in Flammable Storage Cabinet
• Pour larger quantities in fume hood
• NEVER store with oxidizers
• Keep away from heat, ignition sources, and direct sunlight
• Oxidizing Material– Any Hazardous Material which causes
or contributes to the combustion of another material by giving it oxygen
– Eg. Pool & spa test strips, ozone, bleach…
Oxidizers
• Easily oxidize metal powders, organic materials
• Store away from other materials, such as organic solvents
• Wear personal protective equipment (PPE)
• Poisonous & Infectious Materials
(Class 1)– “poisonous”– Causes immediate and serious effects
• Poisonous & Infectious Materials
(Class 2) – Toxic Materials– “toxic” (looks like a capital T)– Material causing other chronic or long
term effects (cancer, birth defects, etc.)
• Poisonous & Infectious Materials
(Class 3)- Biohazards– 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.
• Corrosive Material– Material which may corrode aluminum
and steel or human flesh– Can be liquid or gases

• From “Fight Club”
• Dangerously Reactive Material– 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
General Dry Chemicals
•Relatively innocuous or unreactive
•No special storage requirements
•Relatively innocuous or unreactive
