Ton Containers for the Transportation of Dangerous Goods (CAN/CGSB-43.149)

Current status: Closed

Open on August 24, 2022 and will be closed on October 24, 2022.

The Canadian General Standards Board (CGSB) has released the draft of Safety Standard CAN/CGSB-43.149 for a 60-day consultation period. Safety standard CAN/CGSB-43.149 sets out the requirements for designing, manufacturing, maintaining, qualifying, inspecting, marking, selecting, and using ton containers. 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 ton containers.

This new edition of CAN/CGSB-43.149 will replace Transport Canada standard TP 14877 and it will come into force when it is incorporated by reference within the Transportation of Dangerous Goods Regulations (TDG Regulations) by a later regulatory amendment.
