This blog will serve as a quick reference of the significant changes that may affect you!
This past March 2022, Transport Canada and the Canadian General Standards Board published the new and improved CAN/CGSB-43.146.
The following changes were made in response to the United Nations (UN) updates to the 21st edition of the Model Regulations. The changes also have been a modernization of the exciting regulations that have been around since 2016. This will affect all those who manufacture, inspect, and ship materials utilizing intermediate bulk containers (IBCs) for the purpose of transporting dangerous goods of class 3, 4, 5, 6.1, 8, and 9.
For manufacturers:
- The Marking of Composite IBCs (5.3.), the adding of the packaging group to which the IBC was tested to this section, and more importantly if the makings of the inner receptacle are not visible for inspection, they can be re-transposed to the outer receptacle as long as it’s preceded with the words “inner receptacle”;
- For metal IBC’s simpler detailed on wall thickness in table 3, see below excerpt from the standard
- The addition of Annex E, to provide guidance on emergency pressure-relief for metal IBCs;
- The additional information in regard to modifications of the original design related to size reduction or increase;
- Added definition for protected IBCs and French term for mobile IBCs;
- Clarification of leak proofness test of double-wall IBCs (7.6.4);
- Updates to plastic materials used in IBC’s design, especially recycled plastics.
For users and owners:
- New requirement to Annex C – Periodic leak test and inspection, requiring the owner of IBC to provide a copy of Notice to User to leak test and inspection facility upon request;
- The addition of a pre-test inspection prior to a leak test and a far more detailed procedure (C.3.2);
- In addition to the requirement of a pressure gauge that is used during testing and more notably the gauge must be calibrated on an annual basis.

Remember, it’s the responsibility of ALL that work with IBCs to know their responsibilities and requirements in regard to this standard to ensure compliance with regulations.
