Classification of Mixtures

Marginal note:Order of provisions

 The classification of a mixture as a mixture that causes specific target organ toxicity arising from a single exposure in a category of this hazard class must proceed in accordance with the order of sections 8.8.3 to 8.8.5.

Marginal note:Data available for mixture as a whole

 If data of the types referred to in subparagraphs 2.1(a)(i) to (iv) are available for the mixture as a whole, the mixture must be classified as a mixture that causes specific target organ toxicity arising from a single exposure in accordance with section 8.8.1.

Marginal note:Data available for use of bridging principles

 If data are available to enable the characterization of the mixture as a mixture that causes specific target organ toxicity arising from a single exposure, in accordance with the bridging principles referred to in subsections 2.3(3) to (8), the mixture must be classified in one or more categories of this hazard class, based on the table to subsection 8.8.1(2), in accordance with those subsections.

Marginal note:Data available for ingredients — Category 1, 2 or 3
  •  (1) A mixture that contains one or more ingredients that are classified as a substance that causes specific target organ toxicity arising from a single exposure is classified as follows:

    • (a) in the category “Specific Target Organ Toxicity — Single Exposure — Category 1”, if it contains at least one ingredient at a concentration equal to or greater than the concentration limit of 1.0% that is classified in the category “Specific Target Organ Toxicity — Single Exposure — Category 1”;

    • (b) in the category “Specific Target Organ Toxicity — Single Exposure — Category 2”, if it contains at least one ingredient at a concentration equal to or greater than the concentration limit of 1.0% that is classified in the category “Specific Target Organ Toxicity — Single Exposure — Category 2”; or

    • (c) in the category “Specific Target Organ Toxicity — Single Exposure — Category 3”, if it contains at least one ingredient that is classified in the category “Specific Target Organ Toxicity — Single Exposure — Category 3” that is

      • (i) at a concentration equal to or greater than the concentration at which the effect is elicited, if known,

      • (ii) at a concentration equal to or greater than the concentration limit of 20.0%, or

      • (iii) at a concentration of 1.0% or more that which, when added to the concentration of all other ingredients present individually at a concentration of 1.0% or more and classified in the category “Specific Target Organ Toxicity — Single Exposure — Category 3”, is equal to or greater than the concentration limit of 20.0%.

  • Marginal note:Data available for ingredients — Categories 1 and 3 or 2 and 3

    (2) Despite subsection 2.2(3), a mixture that has been classified in accordance with paragraph (1)(a) or (b) and meets the criteria of paragraph (1)(c) is also classified in the category “Specific Target Organ Toxicity — Single Exposure — Category 3”.

SUBPART 9Specific Target Organ Toxicity — Repeated Exposure

Definitions

Marginal note:Definitions

 The following definitions apply in this Subpart.

organ

organe

organ includes any biological system. (organe)

specific target organ toxicity arising from repeated exposure

toxicité pour certains organes cibles à la suite d’expositions répétées

specific target organ toxicity arising from repeated exposure means specific toxic effects on target organs that arise from repeated exposure to a mixture or substance, including all health effects liable to impair function of the body or any of its parts, whether reversible or irreversible, immediate or delayed, but excludes effects resulting from health hazards addressed by Subparts 1 to 7 and 10 of this Part. (toxicité pour certains organes cibles à la suite d’expositions répétées)

Classification in a Category of the Class

Classification of Substances

Marginal note:Categories

 A substance that causes specific target organ toxicity arising from repeated exposure is classified in a category of this hazard class in accordance with the following table:

TABLE

ItemColumn 1Column 2
CategoryCriteria
1Specific Target Organ Toxicity — Repeated Exposure — Category 1

A substance that

  • (a) according to human data, causes specific target organ toxicity arising from repeated exposure; or

  • (b) according to animal data, causes specific target organ toxicity arising from repeated exposure at low exposure concentrations, within the concentration value ranges set out in Table 3.9.1 of the GHS

2Specific Target Organ Toxicity — Repeated Exposure — Category 2A substance that, according to animal data, causes specific target organ toxicity arising from repeated exposure at moderate exposure concentrations, within the concentration value ranges set out in Table 3.9.2 of the GHS

Classification of Mixtures

Marginal note:Order of provisions

 The classification of a mixture as a mixture that causes specific target organ toxicity arising from repeated exposure in a category of this hazard class must proceed in accordance with the order of sections 8.9.3 to 8.9.5.

Marginal note:Data available for mixture as a whole

 If data of the types referred to in subparagraphs 2.1(a)(i) to (iv) are available for the mixture as a whole, the mixture must be classified as a mixture that causes specific target organ toxicity arising from repeated exposure in accordance with section 8.9.1.

Marginal note:Data available for use of bridging principles

 If data are available to enable the characterization of the mixture as a mixture that causes specific target organ toxicity arising from repeated exposure, in accordance with the bridging principles referred to in subsections 2.3(3) to (8), the mixture must be classified in a category of this hazard class in accordance with those subsections.

Marginal note:Data available for ingredients

 A mixture that contains one or more ingredients that are classified as a substance that causes specific target organ toxicity arising from repeated exposure is classified as follows:

  • (a) in the category “Specific Target Organ Toxicity — Repeated Exposure — Category 1”, if it contains at least one ingredient at a concentration equal to or greater than the concentration limit of 1.0% that is classified in the category “Specific Target Organ Toxicity — Repeated Exposure — Category 1”; or

  • (b) in the category “Specific Target Organ Toxicity — Repeated Exposure — Category 2”, if it contains at least one ingredient at a concentration equal to or greater than the concentration limit of 1.0% that is classified in the category “Specific Target Organ Toxicity — Repeated Exposure — Category 2”.
