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
