SUBPART 4Oxidizing Gases

Definition

Definition of oxidizing gas

 In this Subpart, oxidizing gas means a gas that is liable to cause or contribute to the combustion of other material more than air does.

Classification in the Category of the Class

Marginal note:Category

 An oxidizing gas is classified in the category of this hazard class in accordance with the following table:

TABLE

ItemColumn 1Column 2
CategoryCriteria
1Oxidizing Gases — Category 1A gas that has an oxidizing power > 23.5% based on one of the methods set out in the International Organization for Standardization standard ISO 10156:2010 entitled Gases and gas mixtures — Determination of fire potential and oxidizing ability for the selection of cylinder valve outlets, as amended from time to time

SUBPART 5Gases Under Pressure

Definitions

Marginal note:Definitions

 The following definitions apply in this Subpart.

critical temperature

température critique

critical temperature means the temperature above which a pure gas cannot be liquefied, regardless of the degree of compression. (température critique)

gas under pressure

gaz sous pression

gas under pressure means a product that consists of a gas contained in a receptacle at a gauge pressure of 200 kPa or more at 20°C, or that is liquefied, or liquefied and refrigerated, but excludes any gas that has an absolute vapour pressure of not more than 300 kPa at 50°C or that is not completely gaseous at 20°C and the standard pressure of 101.3 kPa. (gaz sous pression)

Classification in a Category of the Class

Marginal note:Categories

 A gas under pressure is classified in a category of this hazard class in accordance with the following table:

TABLE

ItemColumn 1Column 2
CategoryCriteria
1Gases Under Pressure — Compressed GasA gas that when packaged under pressure is entirely gaseous at -50°C, including all gases with a critical temperature ≤ -50°C
2Gases Under Pressure — Liquefied GasA gas that when packaged under pressure is partially liquid at temperatures > -50°C
3Gases Under Pressure — Refrigerated Liquefied GasA gas that when packaged is partially liquid because of its low temperature
4Gases Under Pressure — Dissolved GasA gas that when packaged under pressure is dissolved in a liquid phase solvent

SUBPART 6Flammable Liquids

Definitions

Marginal note:Definitions

 The following definitions apply in this Subpart.

appropriate closed-cup method

méthode de creuset fermé appropriée

appropriate closed-cup method means the methods listed in paragraph 2.6.4.2.5 of the GHS, as amended from time to time. (méthode de creuset fermé appropriée)

flammable liquid

liquide inflammable

flammable liquid means a liquid that has a flash point of not more than 93°C. (liquide inflammable)

Classification in a Category of the Class

Marginal note:Exclusions
  •  (1) Any product that is classified in a category of the hazard class “Flammable Aerosols” need not be classified in any category of this hazard class.

  • Marginal note:Categories

    (2) A flammable liquid is classified in a category of this hazard class in accordance with the following table:

    TABLE

    ItemColumn 1Column 2
    CategoryCriteria
    1Flammable Liquids — Category 1A liquid that has a flash point < 23°C and initial boiling point ≤ 35°C
    2Flammable Liquids — Category 2A liquid that has a flash point < 23°C and initial boiling point > 35°C
    3Flammable Liquids — Category 3A liquid that has a flash point ≥ 23°C and ≤ 60°C
    4Flammable Liquids — Category 4A liquid that has a flash point > 60°C and ≤ 93°C
  • Marginal note:Determination of flash point — substance

    (3) In the case of a liquid that is a substance, the flash point must be determined by

    • (a) tests using an appropriate closed-cup method; or

    • (b) use of scientific literature that reports a value obtained from an appropriate closed-cup method.

  • Marginal note:Determination of flash point — mixture

    (4) In the case of a liquid that is a mixture, the flash point must be determined by

    • (a) tests using an appropriate closed-cup method; or

    • (b) use of an applicable calculation method under conditions for which it has been validated according to generally accepted standards of good scientific practice at the time the validation was carried out.

SUBPART 7Flammable Solids

Definitions

Marginal note:Definitions

 The following definitions apply in this Subpart.

flammable solid

solide inflammable

flammable solid means a readily combustible solid or a solid that is liable to cause or contribute to fire through friction. (solide inflammable)

readily combustible solid

solide facilement inflammable

readily combustible solid means a powdered, granular or pasty mixture or substance that can be easily ignited by brief contact with an ignition source and, when ignited, has a flame that spreads rapidly. (solide facilement inflammable)

Classification in a Category of the Class

Marginal note:Exclusions
  •  (1) Any product that is classified in a category of the hazard class “Flammable Aerosols” need not be classified in any category of this hazard class.

  • Marginal note:Categories

    (2) A flammable solid that is a readily combustible solid is classified in a category of this hazard class, based on results from testing performed in accordance with the burning rate test in sub-section 33.2.1 of Part III of the Manual of Tests and Criteria, in accordance with the following table:

    TABLE

    ItemColumn 1Column 2
    CategoryCriteria
    1Flammable Solids — Category 1

    A solid that is

    • (a) other than a metal powder, in respect of which

      • (i) the burning time is < 45 s or the burning rate is > 2.2 mm/s, and

      • (ii) the wetted zone does not stop the fire or stops the fire for less than 4 min; or

    • (b) a metal powder, in respect of which the burning time is ≤ 5 min

    2Flammable Solids — Category 2

    A solid that is

    • (a) other than a metal powder, in respect of which

      • (i) the burning time is < 45 s or the burning rate is > 2.2 mm/s, and

      • (ii) the wetted zone stops the fire for at least 4 min; or
