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 will be no accidental 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 the dangerous goods in the inner means of containment

  • (i) if solids, have a mass that is less than or equal to the number shown in column 6(a) of Schedule 1, when that number is expressed in kilograms,

  • (ii) if liquids, have a volume that is less than or equal to the number shown in column 6(a) of Schedule 1, when that number is expressed in litres, or

  • (iii) if gases, including a gas in a liquefied form, are contained in one or more means of containment each of which has a capacity less than or equal to the number shown in column 6(a) of Schedule 1, when that number is expressed in litres.

(2) Part 3 (Documentation), Part 4 (Dangerous Goods Safety Marks), Part 5 (Means of Containment), Part 6 (Training), Part 7 (Emergency Response Assistance Plan) and Part 8 (Reporting Requirements) do not apply to the handling, offering for transport or transporting of limited quantities of dangerous goods on a road vehicle, a railway vehicle or a vessel on a domestic voyage 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 to 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) When 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 small means of containment are visible through the overpack:

• (a) the word “Overpack” or “Suremballage” or ; 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.

(6) Until December 31, 2020, instead of being marked with the mark illustrated in subsection (5), a means of containment may have displayed on it

• (a) the words “Limited Quantity” or “quantité limitée”;

• (b) the abbreviation “Ltd. Qty.” or “quant. ltée”;

• (c) the words “Consumer Commodity” or “bien de consommation”; or

• (d) the UN number of each limited quantity of dangerous goods preceded by the letters “UN”, placed within a square on point.

(7) For the purposes of paragraph 6(d), the line forming the square on point must be black and be at least 2 mm wide. If the dangerous goods have different UN numbers, the square on point must be large enough to include each UN number, but in any case each side must be not less than 50 mm long. The UN numbers and letters must be at least 6 mm high. The line, UN numbers and letters must be on a contrasting background.
