Lesson 1 – WHMIS
- to determine the need for safe handling and guidelines for chemical use and storage
- 1/2 class
You are a part of an advanced civilization, and you need to store some extremely hazardous waste that will not break down for millions of years. Design a label that would warn future people away from the waste. How will you account for different languages and cultures?
There are two main ways that we are given safety information about chemicals.
The first way is a long form called a Material Safety Data Sheet (MSDS). Check out the MSDS for Hydrochloric acid (stomach acid).
The second way is eight symbols that are put on products, called the Workplace Hazardous Materials Information System (WHMIS).
Make a T-chart comparing the similarities and differences between the two systems.
|Similarities between MSDS and WHMIS||Differences between MSDS and WHMIS|
In which circumstance would you want to use a MSDS? A WHMIS symbol?
Fill out the following table:
Divide the class into 8 groups, and assign each group one WHMIS symbol. They need to decide how to act out their symbol (as in Charades) so that the other groups can guess what it is.
