WHMIS & HHPS SYMBOLS Science Safety LEARNING GOALS 1. We are learning the meaning of WHMIS symbols. 2. We are learning the importance of WHMIS & MSDS information.
3. We are understanding the difference between WHMIS & HHPS. Vinegar is a common household chemical that is produced by
diluting (watering down) acetic acid. As shown on the left, this chemical is used to make a variety of products.
WHAT IS WHMIS? Stands for Workplace Hazardous Materials Information System. An internationally recognized system that describes hazards associated with certain materials. Uses symbols found on supplier labels that identify the risks associated with each material, first aid when
necessary and how to properly handle the material. SAMPLE SUPPLIER LABEL WHMIS SYMBOLS
