Study Notes

WHMIS - An Introduction

WHMIS stands for Workplace Hazardous Materials Information System
It was created to provide standard information about hazard identification, safe handling, correct storage and disposal of hazardous materials in order to prevent injuries, illness and death that can be caused by exposure to hazardous materials known as Controlled Products.
WHMIS helps build awareness of potential hazards by providing information to employees through:
- Material safety data sheets (MSDSs)
- Worker education and training programs

WHMIS Classes of Controlled Products

Controlled Products are classified in one or more of the following classes:
- Class A: Compressed Gas
- Class B: Flammable and Combustible Material
- Class C: Oxidizing Material
- Class D: Poisonous and Infectious Material:
  - D1 – Immediate and Serious Toxic Effects
  - D2 – Materials Causing Other Toxic Effects
  - D3 – Biohazardous Infectious Materials
- Class E: Corrosive Material
- Class F: Dangerously Reactive Material

Workplace Labels

There are two types of labels prescribed under WHMIS legislation:
- Supplier Label: required on all Controlled Products distributed to workplaces in Canada
  - Includes the following information:
    - Product Identifier (e.g., common name, trade name - the same as on the MSDS)
    - Supplier Identifier (name and address of supplier)
