Part 29 Workplace Hazardous Materials Information System (WHMIS)


This Part presents all the labelling, material safety data sheet (MSDS) and training requirements for employers and workers that handle controlled products.

  • Sections 398 and 404 allow an employer to store a controlled product without WHMIS, MSDS or label information for no more than 120 days, as long as the employer is actively seeking the supplier label or MSDS and as long as placards are provided in the storage area.
  • Section 406 requires that the information presented on an MSDS be newer than three years old.
