Transportation of Dangerous Goods Regulations

1.17 (1) A quantity of dangerous goods, other than explosives, is a limited quantity if

• (a) the dangerous goods are in one or more means of containment designed, constructed, filled, closed, secured and maintained so that under normal conditions of transport, including handling, there is no release of the dangerous goods that could endanger public safety; and

• (b) each outer means of containment has a gross mass that is less than or equal to 30 kg and

  • (i) if the dangerous goods are a solid or a liquid, the goods in each inner means of containment are in a quantity that is less than or equal to the number shown in column 6(a) of Schedule 1, or

  • (ii) if the dangerous goods are a gas, including a gas in a liquefied form, each means of containment in which they are contained has a capacity less than or equal to the number shown in column 6(a) of Schedule 1.

(2) Parts 3 to 8 do not apply to the offering for transport, handling or transporting of limited quantities of dangerous goods if each means of containment is legibly and durably marked on one side, other than a side on which it is intended to rest or be stacked during transport, with the mark illustrated in subsection (5).

(3) When a limited quantity of dangerous goods is in a means of containment that is inside another means of containment, the inner means of containment is not required to be marked if

• (a) the gross mass of the outer means of containment is less than or equal to 30 kg;

• (b) the outer means of containment is not intended to be opened during transport; and

• (c) the outer means of containment is legibly and visibly marked, on a contrasting background, with the mark illustrated in subsection (5).

(4) If a limited quantity of dangerous goods is in a means of containment that is inside an overpack, the following information must be displayed on the overpack unless the marks on the means of containment are visible through the overpack:

• (a) the word “Overpack” or “Suremballage”, in characters at least 12 mm high on a contrasting background; and

• (b) the mark illustrated in subsection (5), legibly and visibly marked on a contrasting background.

(5) The mark is a square on point, and the line forming the square on point must be at least 2 mm wide. The top and bottom portions must be black and the central portion must be white or a contrasting colour. Each side of the mark must be at least 100 mm long. The letter “Y” may be displayed in the centre of the mark if the limited quantity is in compliance with the ICAO Technical Instructions. If the size of the means of containment so requires, the length of each side may be reduced to not less than 50 mm, provided that the mark remains clearly visible.
