Transport Canada Proposes Changes to the TDG

Posted on: March 6, 2014

Transport Canada has proposed four changes to the Transportation of Dangerous Goods Regulations (TDG). The proposed addition of Part 2.2.1 would require all consignors of dangerous goods to maintain proof of classification for each technical name for two years, from the date on the shipping document. Proof of classification would include documents such as test/lab reports and any information on MSDS use. MSDSs alone will not be sufficient.

Part 3.6.1 would require any consignor, or shipper acting on behalf of a consignor, to sign a document for all dangerous goods (DG) shipments verifying that the shipment complies with every part of the TDG.

Special Provision 90 is proposed for UN1267 and UN1268 and would be added to Schedules 1 and 2. It would require that the packing group (PG) for both of these UN numbers be determined by a specific process used during sampling and flash point testing. All container sizes and all modes of transport would be affected. The Special Provision would require the sampling and testing to be documented and these documents would be retained for two years following the date on the Shipping Document.

The final proposed change is that Rail Car Standard TTP14877 replace CGSB43.147. The revised standard would include a requirement for stub sill inspections, a new design for tank cars carrying certain products such as liquefied natural gas, improved pressure relief valves, and additional safety feature and requirements for tank cars carrying over 120,000 kg and DOT-111 tank cars.
