The Canadian Centre for Occupational Health and Safety has released two online courses on WHMIS 2015, which implements the Globally Harmonized System of Classification and Labelling of Chemicals (GHS).
One course is for managers and supervisors, and is intended to help them understand their duties under the WHMIS 2015 (GHS) legislation. The other course explains the purpose of safety data sheets and the information contained in them.
The law provides for a transition period to GHS. By December 1, 2018, the transition to GHS must be complete for all parties, including employers. By that date, employers should have no hazardous products with old WHMIS labels and safety data sheets.
