Containers for Transport of Dangerous Goods by Rail (CAN/CGSB-43.147)

Current status: Open

Open on June 7, 2022 and will be closed on August 7, 2022.

The Canadian General Standards Board (CGSB) has released the draft of Safety Standard CAN/CGSB-43.147 for a 60-day consultation period. Safety standard CAN/CGSB-43.147 sets out the requirements for designing, manufacturing, maintaining, qualifying, inspecting, marking, selecting and using tank cars. The standard also lays out the requirements for the quality management system and its applicability and the registration of facilities performing manufacture, inspection, maintenance or qualification of tank cars.

This new edition of CAN/CGSB-43.147 will replace Transport Canada standard TP 14877 (which in 2013 had replaced the 2005 edition of CAN/CGSB-43.147). The new edition of CAN/CGSB-43.147 will come into force when it is incorporated by reference within the Transportation of Dangerous Goods Regulations (TDG Regulations) by a later regulatory amendment.
