All work-site personnel who work with or close to controlled products, or who do work involved in the manufacture of a controlled product, must be provided with WHMIS worker education.

All workers who participate in the generic worker education program will receive the same information. But the work-site-specific components of a WHMIS education program will probably vary among groups of workers. The hazard information a person needs to know and the procedures in which a person is trained depends on the work the person performs.
