Transitioning from WHMIS 1988 to WHMIS 2015

The Workplace Hazardous Materials Information System (WHMIS) is changing to adopt new international standards for classifying hazardous materials and providing information on labels and safety data sheets (SDS). This transition will affect all employees at the University of Waterloo and especially those working with chemicals and in labs.

The University must meet the following criteria by December 1, 2018, to comply with the new WHMIS standards:

  • All WHMIS training must be current to the new WHMIS 2015 standard. 
  • All chemicals require WHMIS 2015 safety data sheets and supplier labels. Any chemicals you wish to keep that do not have WHMIS 2015 labelling/signage will require updated labelling by the December 1, 2018 deadline.

Failure to comply may result in penalties from the Ministry of Labour including work stoppages and fines.

This page is here to help Waterloo supervisors navigate through this transition. Please contact the Safety Office if you have any questions.

 September 2018 update

  • The Safety Office is in the process of developing a chemical labelling system that meets WHMIS 2015 requirements. This will allow us to update the labels on chemicals already on campus. Further updates will be provided as we work through the process to meet compliance specifications.   
  • Health and safety coordinators can now request a list of labs in their department that have moved their chemical inventory to erPortal. Contact Dhananjai Borwankar for your list. 

At this time, please ensure that:
