In the July 2, 2014 Canada Gazette, Part II edition, the Government of Canada issued changes to the Transportation of Dangerous Goods Regulations (TDG). The changes can be found in amendments SOR/2014-159 and SOR/2014-152 in the Canada Gazette. And, on July 16, 2014, an Erratum to SOR/2014-159 was issued.

SOR/2014-159 became effective July 14, 2014. Some of the changes include additional definitions added to Section 1.4, such as ‘Consolidation bin’ and ‘Overpack.’ New markings have been added for limited quantities, marine pollutants and organic peroxides (Class 5.2). Limited quantities in ‘Overpacks’ are required to have the phrase “Overpack” or “Suremballage” and the limited quantity symbol visible either on the ‘Overpack’ or clearly visible through the ‘Overpack.’ Sections 4.15 – 4.16 contain numerous changes to the Regulations concerning the visibility of labels, placards and UN numbers on large means of containment. A new section, Section 4.23, has been added to the TDG Regulations. This section requires the use of the phrase “toxic by inhalation” or “toxic – inhalation hazard” on the means of containment for any dangerous good that is toxic by inhalation.

SOR/2014-152 includes changes to the containment regulations for dangerous goods. New requirements have been adopted for portable tanks, small containers and rail containers. Existing TDG regulations for cylinders, spheres, tubes, aerosol containers and tanks have been revised. These changes are meant to harmonize requirements with the United States. Section 2.2.1 has been added, requiring proof of classification to be available for five years. Proof of classification must explain how the dangerous good was classified and can include test reports, lab reports or a safety data sheet (SDS) that is accompanied by a description of how the dangerous goods were classified. SOR/2014-152 became effective July 15, 2014.
