4.18.3 When dangerous goods included in Class 2, Gases, are contained in a combination of tubes 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 tubes may be placarded as if it were one large means of containment.

Placards and UN Numbers on a Compartmentalized Large Means of Containment

• 4.19 (1) When dangerous goods included in different primary classes are transported in different compartments of a compartmentalized large means of containment,

  • (a) the primary class placard and the UN number for the dangerous goods in each compartment must be displayed on each side of that compartment; and

• (3) Despite paragraph (2)(b), if a compartmentalized large means of containment contains UN3475, ETHANOL AND GASOLINE MIXTURE, the number “3475” must be displayed, in addition to the UN number — without the prefix “UN” — of the dangerous goods with the lowest flash point, on each side and on each end of the compartmentalized large means of containment.

Elevated Temperature Sign

• 4.20 (1) In addition to the requirements for placards and UN numbers in section 4.15, the elevated temperature sign must be displayed for dangerous goods that are contained in a large means of containment and that are offered for transport or transported at a temperature greater than or equal to

  • (a) 100°C if the dangerous goods are in a liquid state; and

  • (b) 240°C if the dangerous goods are in a solid state.

• (2) The elevated temperature sign must be displayed on each side and on each end of the large means of containment next to each primary class placard for the dangerous goods or, if there is a subsidiary class placard, next to the subsidiary class placard.
