It is essential to exercise competent technical and engineering judgment in conjunction with this standard. It is the responsibility of the IBC manufacturer to ensure that the IBC will safely carry out its intended function within these constraints. 1.4 Transportation of Dangerous Goods Act and Regulations prevalence The Transportation of Dangerous Goods Act (TDG Act), 1992 and the Transportation of Dangerous Goods Regulations (TDG Regulations) may call for additional requirements regarding the design, construction, qualification, selection, use, and testing of means of containment. Where there is an inconsistency between the requirements of this standard and those of the TDG Act or TDG Regulations, the Act or Regulations prevail to the extent of the inconsistency. regulatory authority. It is recommended to read the standard in conjunction with the TDG Regulations. 1.5 Safety The testing and evaluation of a product against this standard may require the use of materials and/or equipment that could be hazardous.
