Hazardous Products Regulations — 7.8.1
Exclusions 7.8.1 (1) The following need not be classified in any category of this hazard class: (a) mixtures or substances, or mixtures or substances as packaged, that are classified in a category of the hazard class “Organic Peroxides”; (b) liquid or solid mixtures that are classified in a category of the hazard class “Oxidizing Liquids” or “Oxidizing Solids”, and contain less than 5.0% of combustible organic substances; and (c) liquid or solid substances that are classified in a category of the hazard class “Oxidizing Liquids” or “Oxidizing Solids”. Categories (2) Subject to subsection (3), a self-reactive substance or mixture is classified in a category of this hazard class, based on results from testing performed in accordance with test series A to H of Part II of the Manual of Tests and Criteria, in accordance with the following table: TABLE Column 1 Column 2 Item Category Criteria 1 Self-reactive Substances and Mixtures — Type A A liquid or solid that, as packaged, is liable to detonate, or deflagrate rapidly 2 Self-reactive Substances and Mixtures — Type B A liquid or solid that possesses explosive properties and, as packaged, neither detonates, nor deflagrates rapidly, but is liable to undergo a thermal explosion in that package 3 Self-reactive Substances and Mixtures — Type C A liquid or solid that possesses explosive properties and, as packaged, neither detonates, nor deflagrates rapidly nor undergoes a thermal explosion in that package 4 Self-reactive Substances and Mixtures — Type D In laboratory testing, a liquid or solid that (a) detonates partially, does not deflagrate rapidly and shows no violent effect when heated under confinement; (b) does not detonate, deflagrates slowly and shows no violent effect when heated under confinement; or (c) neither detonates nor deflagrates, and shows a medium effect when heated under confinement 5 Self-reactive Substances and Mixtures — Type E In laboratory testing, a liquid or solid that neither detonates nor deflagrates and shows low or no effect when heated under confinement 6 Self-reactive Substances and Mixtures — Type F In laboratory testing, a liquid or solid that neither detonates in the cavitated state nor deflagrates and (a) shows low or no effect when heated under confinement, as well as low or no explosive power; or (b) shows no effect when heated under confinement nor any explosive power, and either (i) has a SADT < 60°C when evaluated in a 50 kg package, or (ii) in the case of a liquid mixture, has a diluent that is used for desensitization with a boiling point < 150°C 7 Self-reactive Substances and Mixtures — Type G In laboratory testing, a liquid or solid that neither detonates in the cavitated state nor deflagrates, shows no effect when heated under confinement nor any explosive power, and either (a) has a SADT of 60°C to 75°C when evaluated in a 50 kg package, or (b) in the case of a liquid mixture, has a diluent that is used for desensitization with a boiling point ≥ 150°C Exclusion after evaluation (3) A mixture or substance with a self-accelerating decomposition temperature greater than 75°C when evaluated in a 50 kg package need not be classified in any category of this hazard class.
