Transportation of Dangerous Goods Regulations

4.10 (1) Subject to subsections (2) to (8), for each of the dangerous goods in transport in a small means of containment, one label must be displayed on the small means of containment for the primary class and one for each subsidiary class, if any.

(2) A label is not required to be displayed on the small means of containment if the small means of containment is inside another small means of containment that displays the label and that is not opened during loading or unloading or while the dangerous goods are in transport.

(3) Instead of the labels referred to in subsection (1), the oxidizing gas label may be displayed on the small means of containment if the small means of containment contains any of the following dangerous goods:

• (a) UN1072, OXYGEN, COMPRESSED;

• (b) UN1073, OXYGEN, REFRIGERATED LIQUID;

• (c) UN3156, COMPRESSED GAS, OXIDIZING, N.O.S.;

• (d) UN3157, LIQUEFIED GAS, OXIDIZING, N.O.S.

(4) If the small means of containment contains dangerous goods included in Class 7, the applicable label for Class 7 must be displayed on two opposite sides of the small means of containment, in addition to any subsidiary class labels required under subsection (1).

(5) If the dangerous goods are included in Class 2 and are contained in a combination of cylinders, each cylinder having a capacity greater than 225 L, that are a single unit as a result of being interconnected through a piping arrangement and are permanently mounted on a structural frame for transport, the combination of cylinders may be placarded as one large means of containment, instead of displaying the labels required under subsection (1).

(6) If the dangerous goods are included in Class 2 and are contained in a cylinder, the cylinder may be marked in accordance with Appendix A of CGA C-7 instead of displaying the labels required under subsection (1).

(7) If the dangerous goods are contained in a non-specification container referred to in section 5.5.4 or 5.5.5 of CSA B340, no labels are required to be displayed on the container.

(8) Despite subsection (4), a Class 7 label is not required to be displayed on a small means of containment that contains radioactive material if the shipping name and UN number of the radioactive material are displayed on the small means of containment and

• (a) the radioactive material is contained in an exposure device, as defined in section 1 of the Nuclear Substances and Radiation Devices Regulations, and the small means of containment is marked in accordance with paragraph 28(2)(a) of the Packaging and Transport of Nuclear Substances Regulations, 2015; or

• (b) the radioactive material is LSA-I material, within the meaning of subsection 5(1) of the Packaging and Transport of Nuclear Substances Regulations, 2015, and does not have any subsidiary classes and the small means of containment is marked in accordance with subparagraphs 28(2)(c)(iii) and (iv) of those Regulations.

(9) For the purposes of subsection (1), the primary class label that must be displayed on a small means of containment that contains any of the following dangerous goods is the Class 9 label specific to lithium batteries:

• (a) UN3090, LITHIUM METAL BATTERIES;

• (b) UN3091, LITHIUM METAL BATTERIES CONTAINED IN EQUIPMENT or LITHIUM METAL BATTERIES PACKED WITH EQUIPMENT;

• (c) UN3480, LITHIUM ION BATTERIES;

• (d) UN3481, LITHIUM ION BATTERIES CONTAINED IN EQUIPMENT or LITHIUM ION BATTERIES PACKED WITH EQUIPMENT.

(10) A label required by this Part must be displayed

• (a) on any side of the outer surface of the small means of containment, other than the side on which the small means of containment is intended to rest or to be stacked during transport, as long as the label and all other dangerous goods marks required to be displayed on the small means of containment under this Part are visible from the same viewpoint;

• (b) on or near the shoulder of a cylinder containing dangerous goods; or

• (c) in the case of a label for dangerous goods included in Class 7, on two opposite sides of the outer surface of the small means of containment but not on the side on which the small means of containment is intended to rest or to be stacked during transport.

(11) Despite subsection (10), a label with sides that are reduced in length to not less than 30 mm in length under subsection 4.7(3) may be displayed on a tag that is securely attached to the small means of containment.
