• Duties of the Supplier– Classify Product

– Apply Supplier Label

– Provide Material Safety Data Sheet

Responsibilities Under WHMIS

• Duties of the Employer– Conduct Workplace Inventory

– Ensure Proper Labeling is Used

– Label Piping Systems/Vessels/Reactors

– 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”

• Worker’s have Access to Information through their Employer

• Public has Access to Information through Local Medical Officer of Health

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– Flammable Gases

– Flammable and Combustible Liquids

– Flammable Solids

– Flammable Aerosols

– Reactive Flammable Material

Flammable Materials

• Store liquids in Flammable Storage Cabinet

• Explosion-proof fixtures required

• Pour larger quantities in fume hood

• NEVER store with oxidizers

• Keep away from heat, ignition sources, and direct sunlight

• Use static lines when transferring

• Oxidizing Material– Any Hazardous Material which causes or

contributes to the combustion of another material by giving oxygen or some other oxidizing substance, whether or not it is combustible.

– Eg. Pool & spa test strips, ozone, bleach…

Oxidizers

• Easily oxidize metal powders, organic materials

• Segregate from other materials, such as organic solvents

• PPE and/or Explosion barriers may be required

• Poisonous & Infectious Materials

(Class 1)– Material causing immediate and serious

toxic effects

– Materials which are potentially fatal or may cause permanent damage if inhaled, swallowed, or absorbed through the skin, or may burn the skin or eyes upon contact

• Poisonous & Infectious Materials

(Class 2) – Toxic Materials– Material causing other chronic or long term

effects

– Material which may cause death or permanent damage as a result of repeated exposure over an extended period of time; may be an irritant to the skin, eyes, or respiratory system; may cause cancer, birth defects, or sterility.

• 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

• 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
