Controlled Products Regulations (SOR/88-66)

Regulations are current to 2014-10-15 and last amended on 2010-02-23. Previous Versions

Division 5: Flammable Aerosols

 Any product, material or substance falls into Division 5 of Class B — Flammable and Combustible Material if it is packaged in an aerosol container and, when tested in accordance with the method set out in Schedule VI, yields a flame projection at full valve opening or a flashback at any degree of valve opening.

Division 6: Reactive Flammable Materials

 Any product, material or substance falls into Division 6 of Class B — Flammable and Combustible Material if

  • (a) it is spontaneously combustible and liable to spontaneous heating under normal conditions of use or liable to heat in contact with air to the point where it begins to burn; or

  • (b) it emits a flammable gas or becomes spontaneously combustible on contact with water or water vapour.

Class C — Oxidizing Material

 Any product, material or substance shall be included in Class C — Oxidizing Material listed in Schedule II to the Act if

  • (a) it causes or contributes to the combustion of another material by yielding oxygen or any other oxidizing substance, whether or not the product, material or substance is itself combustible; or

  • (b) it is an organic peroxide that contains the bivalent 0-0 structure.

Class D — Poisonous and Infectious Material

General

  •  (1) The products, materials and substances referred to in sections 46 to 64 shall be included in Class D — Poisonous and Infectious Material listed in Schedule II to the Act.

  • (2) Divisions 1 to 3 are established as divisions of Class D — Poisonous and Infectious Material listed in Schedule II to the Act.

  • (3) Subdivisions A and B are established as subdivisions of Divisions 1 and 2 of Class D — Poisonous and Infectious Material listed in Schedule II to the Act.

  • (4) A gas included in Division 4 of Class 2 in Part III of the Transportation of Dangerous Goods Regulations does not fall into Division 1 or Division 2 of Class D — Poisonous and Infectious Material.

Formulae for Equivalent LC50

 For the purpose of establishing that a product, material or substance falls into Division 1 of Class D — Poisonous and Infectious Material, an LC50 that is obtained in an animal assay at an exposure duration of other than four hours may be converted to an LC50 equivalent to an exposure duration of four hours by using the following formulae:

  • (a) for a gas or vapour,

    LC50 at Y hours × (Y hours)½ ÷ 2 = LC50 at 4 hours; and

  • (b) for dust, mist or fume,

    LC50 at Y hours × (Y hours) ÷ 4 = LC50 at 4 hours.

    Note: Y = actual number of hours of exposure duration.

Toxicological Evaluation of Mixtures: LD50 and LC50 Data

  •  (1) Subject to subsection (3), where the LD50 or LC50 of every ingredient of a mixture present at a concentration of one per cent or more is known, the LD50 or LC50 of the mixture shall be determined, taking into account all ingredients present at a concentration of one per cent or more, by using the following formulae:

    • (a) for a solid or a liquid,

      1LD50 of mixture=proportion of ingredient ALD50 of ingredient A+proportion of ingredient BLD50 of ingredient B+ ... +proportion of last ingredientLD50 of last ingredient
    • (b) for a gas, vapour, dust, mist or fume,

      1LC50 of mixture=proportion of ingredient ALC50 of ingredient A+proportion of ingredient BLC50 of ingredient B+ ... +proportion of last ingredientLC50 of last ingredient

    Note: proportion = the weight of the ingredient divided by the weight of the mixture.

  • (2) Subject to subsection (3), where the LD50 or LC50 of one or more ingredients of a mixture is not known, the LD50 or LC50 of the mixture is equal to the LD50 or LC50 of the most acutely lethal ingredient that is present in the mixture at a concentration of one per cent or more and for which LD50 or LC50 data is available.

  • (3) The LD50 or LC50 of a mixture may be determined by testing the mixture.
