Yes. WHMIS laws apply to the use of controlled products in all Canadian workplaces, including laboratories. Ideally, controlled products (those products that fall under WHMIS laws) used in laboratories will be fully labelled and accompanied by a material safety data sheet (MSDS).
However, some categories of exemptions were created in the WHMIS laws to allow for flexibility for laboratory samples and products from laboratory supply houses. Exemptions were made because persons working in laboratories are typically better informed about the hazards and necessary precautions of the products in their workplace.
The exemption covers laboratory samples which are controlled products, are packaged in containers of less than 10 kilograms, and for which an MSDS has not been obtained or prepared for the product(s). In this case, the label must have the following information (in both English and French):
Material safety data sheets are not required for controlled products which are supplied by laboratory supply houses, packaged in containers of less than 10 kilograms, and intended for use in laboratories only. In this case, the label must have the following information:
Labels do not require a supplier identification, hazard symbols, nor the "hatched" WHMIS border.
If a product from a laboratory supply house is used outside of a laboratory, then all of the normal WHMIS requirements apply.
Infectious agents are typically only used in laboratories or scientific settings. The Public Health Agency of Canada (Office of Laboratory Security) has prepared Pathogen Safety Data Sheets (PSDSs) [formerly titled MSDS for pathogens] for many of the common infectious agents. Because workers in laboratories are in scientific settings and may be exposed to much higher concentrations of these agents than the general public, the terminology in these safety sheets is technical and detailed. They can be viewed on their web site.
Sometimes. WHMIS laws do not apply if:
In general, the basis for these exemptions is that the precautions that must be used when handling radioactive materials will provide a considerable safety margin that will cover any precautions that the carrier material may require.
WHMIS laws apply to controlled products (those listed under the Controlled Product regulation). Distribution of substances (such as from one hospital to another which both operate under the same Ministry of Health) is outside of the WHMIS laws. For substances which are not sold in Canada, employers should check with their local occupational health and safety agency or health agency for more information.
Add a badge to your website or intranet so your workers can quickly find answers to their health and safety questions.
