Highway Tanks and Portable Tanks for the Transportation of Dangerous Goods
|Publication Date:||1 October 1987|
This Standard applies to highway tanks and portable tanks used for the transportation of dangerous goods in bulk by road and for intermodal portable tanks for the transportation of dangerous goods in bulk, other than by air. It covers the design, construction, certification, testing, inspection and retesting, maintenance, and identification of such tanks. Additional design and construction requirements for tanks intended to carry specific products are covered in the following CSA Standards:
Selection and Use of Highway Tanks, Portable Tanks, Cargo Compartments and Containers for the Transportation of Dangerous Qoods, Classes 3,4,5, 6, and 8, in Bulk by Road;
Selection and Use of Highway Tanks, Multi-unit Tank Car Tanks, and Portable Tanks for the Transportation of Dangerous Goods, Class 2, by Road;
Selection, Handling, and Use of Intermodal Portable Tanks for the Transportation of Dangerous Goods, Other Than by Air.
Notwithstanding the provisions of this Standard, compliance with the provisions of the Transportation of Dangerous Goods Act of 1980 and the Regulations thereto may call for additional requirements due to particular characteristics or properties of individual dangerous goods. The design, construction, testing or retesting of highway tanks (including those for dangerous wastes), portable tanks, intermodal port¬able tanks, or reinforced plastic (RP) highway tanks shall be in accordance with the requirements of this Standard and any additional requirements of the Transportation of Dangerous Goods Regulations.
This Standard is not intended to be a guide for the design and construction of tanks and as such does not obviate the need for exercising competent engineering judgement, nor does it eliminate the necessity for complete design calculations relating to the intended use of the tank. The values for the various parameters listed are simply the limiting values within which such tanks are restricted for this Standard. It is the responsibility of the tank manu¬facturer to select adequate values (of safety factor, tensile strength, etc) within these constraints, so that the tank will safely carry out its intended function
