WHMIS, HHPS & General Science Safety

What is WHMIS?

This system was developed to provide workers and students with complete and accurate information regarding hazardous products. All chemical products that are used in business, workplaces, industry or schools must contain standardized labels and must be accompanied by Material Safety Data Sheet (MSDS) in a location convenient to the worker or student. The MSDS sheet must provide clear and precise information about the product. Clear and standardized labeling of products is an important component of WHMIS. The labels must be present on the product's original container or a label must be created and added to any container the product is added to.

House Hold Product Symbols (HHPS)

The Canadian Hazardous Products Act requires manufacturers of consumer products containing chemicals to include a symbol that specifies both the nature of the primary hazard and the degree of this hazard. In addition, any secondary hazards, first-aid treatment, storage, and disposal must be noted. These are theHouse Hold Product Symbols (HHPS). What do these symbols mean?


______ /
______ /
______ /
______

These symbols are surrounded by one of two signs shapes. The number of sides indicates the degree of danger. The stop sign with 8 sides poses a greater danger than the yield sign with 3 sides. What do these symbols mean?
