It includes GI #2 and #3. 1.1 This Standard applies to tanks, other than intermediate bulk containers, or tubes used for the transportation of dangerous goods primarily by road, and to intermodal portable tanks for the transportation of dangerous goods, other than by air.

It considers the design, construction, certification, assembly, modification, repair, testing, inspection and periodic re- testing, maintenance, and identification of such tanks.

Additional design and construction requirements for tanks intended to carry specific products are provided in the following CSA Standards:

B621-98, Selection and Use of Highway Tanks, Portable Tanks, Cargo Compartments, and Containers for the Transportation of Dangerous Goods, Classes 3, 4, 5, 6.1, 8, and 9; and

B622-98, Selection and Use of Highway Tanks, Multi-Unit Tank Car Tanks, and Portable Tanks for the Transportation of Dangerous Goods, Class 2.

1.2 The Transportation of Dangerous Goods Act, 1992, and the Transportation of Dangerous Goods Regulations may set out requirements that are additional to or different from those in this Standard due to particular characteristics or properties of individual dangerous goods.

Where there is an inconsistency between the requirements of this Standard and those of the Act or Regulations, the Act or Regulations prevail to the extent of the inconsistency.

1.3 The use of this Standard does not reduce the necessity for competent engineering judgement or complete design calculations that take into account the intended use of the tank. The values of the various parameters in this Standard are the limiting values to which the tank is restricted. It is the responsibility of the tank manufacturer to ensure that the tank will safely carry out its intended function within these constraints. See more
