Classification of Mixtures

Marginal note:Order of provisions

 The classification of a mixture as a respiratory sensitizer or a skin sensitizer, or both, in one or more categories of this hazard class must proceed in accordance with the order of sections 8.4.3 to 8.4.5.

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 respiratory sensitizer or a skin sensitizer, or both, in accordance with section 8.4.1.

Marginal note:Data available for use of bridging principles

 If data are available to enable the characterization of the mixture as a respiratory sensitizer or a skin sensitizer, or both, 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 is classified as a respiratory sensitizer or as a skin sensitizer, or both, as the case may be, in accordance with the following:

  • (a) as a respiratory sensitizer,

    • (i) in the category “Respiratory Sensitizer — Category 1”, if it contains at least one ingredient at a concentration equal to or greater than the concentration limit of 0.1% that is classified in the category “Respiratory Sensitizer — Category 1”,

    • (ii) in the subcategory “Respiratory Sensitizer — Category 1A”, if it contains at least one ingredient at a concentration equal to or greater than the concentration limit of 0.1% that is classified in the subcategory “Respiratory Sensitizer — Category 1A”, or

    • (iii) in the subcategory “Respiratory Sensitizer — Category 1B”, if it does not contain ingredients classified in the subcategory “Respiratory Sensitizer — Category 1A” at a concentration equal to or greater than the concentration limit of 0.1% and

      • (A) it contains at least one ingredient that is a solid or a liquid at a concentration equal to or greater than the concentration limit of 1.0% that is classified in the subcategory “Respiratory Sensitizer — Category 1B”, or

      • (B) it contains at least one ingredient that is a gas at a concentration equal to or greater than the concentration limit of 0.2% that is classified in the subcategory “Respiratory Sensitizer — Category 1B”; or

  • (b) as a skin sensitizer,

    • (i) in the category “Skin Sensitizer — Category 1”, if it contains at least one ingredient at a concentration equal to or greater than the concentration limit of 0.1% that is classified in the category “Skin Sensitizer — Category 1”,

    • (ii) in the subcategory “Skin Sensitizer — Category 1A”, if it contains at least one ingredient at a concentration equal to or greater than the concentration limit of 0.1% that is classified in the subcategory “Skin Sensitizer — Category 1A”, or

    • (iii) in the subcategory “Skin Sensitizer — Category 1B”, if it does not contain ingredients classified in the subcategory “Skin Sensitizer — Category 1A” at a concentration equal to or greater than the concentration limit of 0.1% and 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 subcategory “Skin Sensitizer — Category 1B”.
