Ideas to be Developed

Working with chemicals can be hazardous. People who are exposed to hazardous substances may be at risk for many serious health problems which could lead to kidney or lung damage, allergic reactions, burns, sterility, or cancer. Workplace Hazardous Materials Information System (WHMIS, pronounced WI-miss) provides health and safety information about hazardous materials. The system teaches what a product's hazards are, how we can protect themselves from exposure, and what to do in case of an emergency or a spill.

For every chemical we handle, we should read and have a general understanding of:

  • the supplier label that is on the bottle and
  • the Material Safety Datasheets that are shipped with the chemical.
This is the WHMIS information and it will help us work safely with and near hazardous materials.

Supplier labels contain hazard symbols. There are 8 hazard symbols. Put your mouse over the symbol to get more information on these symbols.

Compressed gas Flammable or Combustible material Oxidizing material Poisonous and infectious material Materials causing other toxic effects
Biohazardous infectious material Corrosive material Dangerously reactive material


A Material Safety Datasheet is information about a specific chemical.

Key Words

WHMIS - Workplace Hazardous Materials Information System is a system that provides health and safety information about the workplace hazardous materials.

supplier labels - These labels are found on the containers to identify the product, hazards and precautionary measures.

MSDS - Material Safety Datasheets provides specific hazard information, safe handling information and emergency procedures of treatment.


Materials Required
MSDS sheets (available in the classroom and on the Internet)

Procedure
Using MSDS sheets, students will identify the eight given aspects of a given chemical.

Observations
Has the student accurately identified the parts of the MSDS sheets?

Summary
