Class A — Compressed Gas

 Any product, material or substance contained under pressure, including compressed gas, dissolved gas or gas liquefied by compression or refrigeration, that has any of the following characteristics shall be included in Class A — Compressed Gas listed in Schedule II to the Act:

  • (a) a critical temperature of less than 50°C (122°F);

  • (b) an absolute vapour pressure greater than 294 kilopascals (2.90 atmospheres) at 50°C (122°F);

  • (c) an absolute pressure in the cylinder or other pressure vessel in which it is packaged greater than 275±1 kilopascals (2.71±0.01 atmospheres) at 21.1°C (70°F) or 717±2 kilopascals (7.07±0.02 atmospheres) at 54.4°C (130°F); or

  • (d) in a liquid state, an absolute vapour pressure exceeding 275 kilopascals (2.71 atmospheres) at 37.8°C (100°F) as determined by the Standard Test Method for Vapor Pressure of Petroleum Products (Reid Method), ASTM D323-82, dated August 27, 1982.

  • SOR/97-543, s. 21.

Class B — Flammable and Combustible Material

  •  (1) The products, materials and substances referred to in sections 36 to 41 shall be included in Class B — Flammable and Combustible Material listed in Schedule II to the Act.

  • (2) Divisions 1 to 6 are established as divisions of Class B — Flammable and Combustible Material listed in Schedule II to the Act.

Division 1: Flammable Gases

 Any product, material or substance falls into Division 1 of Class B — Flammable and Combustible Material if it is a compressed gas included in Class A — Compressed Gas that, at normal atmospheric pressure forms a flammable mixture with air

  • (a) when in a concentration of 13 per cent or less by volume; or

  • (b) over a concentration range of at least 12 per cent by volume.

Division 2: Flammable Liquids

 Any product, material or substance falls into Division 2 of Class B — Flammable and Combustible Material if it is a liquid that has a flash point of less than 37.8°C (100°F), when tested in accordance with the applicable method specified in Schedule IV for that type of liquid.

Division 3: Combustible Liquids

 Any product, material or substance falls into Division 3 of Class B — Flammable and Combustible Material if it is a liquid that has a flash point of 37.8°C (100°F) or more but less than 93.3°C (200°F), when tested in accordance with the applicable method specified in Schedule IV for that type of liquid.

Division 4: Flammable Solids

 Any product, material or substance falls into Division 4 of Class B — Flammable and Combustible Material if it is a solid that

  • (a) causes fire through friction or through retained heat from manufacturing or processing;

  • (b) can be ignited readily and when ignited burns so vigorously and persistently as to create a hazard;

  • (c) ignites readily and burns with a self-sustained flame at a rate of more than 0.254 centimetre (0.1 inch) per second along its major axis, when tested in accordance with the method set out in Schedule V; or

  • (d) is included in Division 1 of Class 4 of Part III of the Transportation of Dangerous Goods Regulations.
