Labels on Hazardous Products HHPS and WHMIS Symbols
Household Hazardous Product Symbols (HHPS) • Many products used in our homes may be dangerous if used incorrectly. • For this reason, household products are marked with symbols that allow us to recognize and interpret potential hazards
Each symbol has two components: • Its shape tells you how hazardous a product is:
Within each shape are symbols that tell you what kind of hazard the product is:
Identify the meaning of the following symbols: Danger Corrosive Warning Toxic Caution Flammable Caution Explosive
WHMIS SYMBOLS • The Workplace Hazardous Materials Information System (WHMIS) has produced symbols for hazardous products found in the workplace. • WHMIS symbols are similar to HHPS symbols, but are always in a circle • WHMIS symbols identify a wider range of hazards than HHPS symbols
WHMIS LABELS • WHMIS labels are affixed or attached to the containers of controlled products, and provide information that: • Alerts the user to the hazards of the product • States what precautions to take when handling the product. • Refers the user to a material safety data sheet (MSDS) for more detailed information about the product.
