What is happening?
Canada has amended its Hazardous Products Regulations through the Government of Canada Gazette published on December 15, 2022. These updates are designed to comply with the most recent requirements in the United Nations document entitled Globally Harmonized System of Classification and Labelling of Chemicals (GHS), Seventh Revised Edition. (SGH), Manual of Tests and Criteria, for the classification of hazardous products worldwide.
The changes are detailed in the Canada Gazette: https://www.gazette.gc.ca/rp-pr/p2/2023/2023-01-04/html/sor-dors272-eng.html
What is changing?
Two new physical hazard classes:
- Chemicals under pressure
- Changes to the hazard classification methods
- Changes to product testing procedures
- Changes to which data is presented in an SDS
When do the changes take effect?
These changes came into force on the day on which they were published in the Gazette on December 15th, 2022.
There is a three-year (3) transition period. So after December 15th, 2025 all employers, suppliers, manufacturers and trainers must be in compliance with these amendments.
How is Training affected?
YOW Canada’s Training will be updated with the following:
