1. WHMIS
WHMIS = Workplace Hazardous Materials Information System
Purpose:
● Provides info on storing, handling, and disposing of workplace chemicals
● Includes first aid information
● All hazardous materials must have a WHMIS label
● Labels use symbols so you don’t need to memorize instructions—just recognize
the icons
WHMIS Hazard Classes
1. Flammability
○ Materials that easily catch fire and burn in air
