PART 2Classification (continued)

Class 5, Oxidizing Substances and Organic Peroxides (continued)

Packing Groups

  •  (1) The packing group for a substance that is included in Class 5.1, Oxidizing Substances, must be determined by using a test sample of the substance that

    • (a) in the case of a solid, is prepared in accordance with section 2.5.2.2 of Chapter 2.5 of the UN Recommendations; and

    • (b) in the case of a liquid, is prepared in accordance with section 2.5.2.3 of Chapter 2.5 of the UN Recommendations.

  • (2) In the case of a solid substance included in Class 5.1, Oxidizing Substances, the test procedure set out in either subsection 34.4.1 (test O.1) or subsection 34.4.3 (test O.3) of Part III of the Manual of Tests and Criteria must be carried out on the test sample. The substance is included in

    • (a) Packing Group I, if the test sample exhibits an average burning time that is

      • (i) less than the mean burning time of a 3:2 potassium bromate/cellulose mixture by mass when test O.1 is used, or

      • (ii) greater than the mean burning rate of a 3:1 calcium peroxide/cellulose mixture by mass when test O.3 is used;

    • (b) Packing Group II, if the criteria for Packing Group I are not met and the test sample exhibits an average burning time that is

      • (i) less than or equal to the mean burning time of a 2:3 potassium bromate/cellulose mixture by mass, when test O.1 is used, or

      • (ii) equal to or greater than the mean burning rate of a 1:1 calcium peroxide/cellulose mixture by mass, when test O.3 is used; or

    • (c) Packing Group III, if the criteria for Packing Groups I and II are not met and the test sample exhibits an average burning time that is

      • (i) less than or equal to the mean burning time of a 3:7 potassium bromate/cellulose mixture by mass, when test O.1 is used, or

      • (ii) equal to or greater than the mean burning rate of a 1:2 calcium peroxide/cellulose mixture by mass, when test O.3 is used.

  • (2.1) In the case of a liquid substance included in Class 5.1, Oxidizing Substances, the test procedure set out in sub-section 34.4.2 (test O.2) of Part III of the Manual of Tests and Criteria must be carried out on the test sample. The substance is included in

    • (a) Packing Group I, if the test sample in a 1:1 mixture by mass of substance and cellulose spontaneously ignites or the mean pressure rise time is less than that of a 1:1 mixture by mass of 50% perchloric acid and cellulose;

    • (b) Packing Group II, if the mean pressure rise time is less than or equal to the mean pressure rise time of a 1:1 mixture by mass of 40% aqueous sodium chlorate solution and cellulose and the criteria for inclusion in Packing Group I are not met; or

    • (c) Packing Group III, if the mean pressure rise time is less than or equal to the mean pressure rise time of a 1:1 mixture by mass of 65% aqueous nitric acid solution and cellulose and the criteria for inclusion in Packing Group I or II are not met.

  • (3) Class 5.2, Organic Peroxides, are included in Packing Group II.

  • (4) The type, B to F, of organic peroxides must be determined in accordance with section 2.5.3.3 of Chapter 2.5 of the UN Recommendations.

Class 6, Toxic and Infectious Substances

General

 Substances are included in Class 6 if they are

  • (a) liable to cause death or serious injury or to harm human health if swallowed or inhaled or if they come into contact with human skin; or

  • (b) infectious substances.

Divisions

 Class 6 has two divisions:

  • (a) Class 6.1, Toxic Substances, which consists of substances that are liable to cause death or serious injury or to harm human health if swallowed or inhaled or if they come into contact with human skin; and

  • (b) Class 6.2, Infectious Substances, which consists of infectious substances.

Criteria for Inclusion in Class 6.1, Toxic Substances

 A substance is included in Class 6.1

  • (a) due to oral toxicity if its LD50 (oral) is less than or equal to 300 mg/kg;

  • (b) due to dermal toxicity if its LD50 (dermal) is less than or equal to 1 000 mg/kg; or

  • (c) due to inhalation toxicity

    • (i) by dust or mist if dust or mist is likely to be produced in a transport accident and its LC50 (inhalation) is less than or equal to 4 mg/L, or

    • (ii) by vapour if its LC50 (inhalation) is less than or equal to 5 000 mL/m3.

  • SOR/2008-34, s. 34

Packing Groups

  •  (1) When a substance is known to be included in Class 6.1 and that knowledge is based on documentary evidence published in technical journals or government publications and testing is not done to determine the packing group, the substance must be included in Packing Group I.

  • (2) Substances that are included in Class 6.1 due to

    • (a) oral toxicity are included in one of the following packing groups:

      • (i) Packing Group I, if the LD50 (oral) is less than or equal to 5 mg/kg,

      • (ii) Packing Group II, if the LD50 (oral) is greater than 5 mg/kg but less than or equal to 50 mg/kg, or

      • (iii) Packing Group III, if the LD50 (oral) is greater than 50 mg/kg but less than or equal to 300 mg/kg;

    • (b) dermal toxicity are included in one of the following packing groups:

      • (i) Packing Group I if the LD50 (dermal) is less than or equal to 50 mg/kg,

      • (ii) Packing Group II if the LD50 (dermal) is greater than 50 mg/kg but less than or equal to 200 mg/kg, or

      • (iii) Packing Group III if the LD50 (dermal) is greater than 200 mg/kg but less than or equal to 1 000 mg/kg;

    • (c) inhalation toxicity by dust or mist are included in one of the following packing groups:

      • (iii) Packing Group III if the LC50 (inhalation) is greater than 2 mg/L but less than or equal to 4 mg/L; or

    • (d) inhalation toxicity by vapour are included in one of the following packing groups, where “V” is the saturated vapour concentration in millilitres per cubic metre of air at 20°C and at 101.3 kPa:

      • (i) Packing Group I, if

        • (A) V is greater than or equal to 10 multiplied by the LC50, and

        • (B) the LC50 is less than or equal to 1 000 mL/m3,

      • (ii) Packing Group II, if

        • (A) V is greater than or equal to the LC50,

        • (B) the LC50 is less than or equal to 3 000 mL/m3, and

        • (C) the criteria for Packing Group I are not met, or

      • (iii) Packing Group III, if

        • (A) V is greater than or equal to 0.2 multiplied by the LC50,

        • (B) the LC50 is less than or equal to 5 000 mL/m3, and

Determination of LD50 (oral or dermal)

 LD50 (oral or dermal) values for solid or liquid substances or for a mixture of solid or liquid substances must be determined

  • (b) in accordance with section 2.6.2.3 of Chapter 2.6 of the UN Recommendations; or
