Flammable Liquids Bulk Storage Regulations

C.R.C., c. 1148

RAILWAY SAFETY ACT

Regulations Respecting the Design, Location, Construction, Operation and Maintenance of Stationary Bulk Storage Facilities for Flammable Liquids

Short Title

 These Regulations may be cited as the Flammable Liquids Bulk Storage Regulations.

Interpretation

  •  (1) In these Regulations,

    boil-over

    boil-over is a term used to describe the action that occurs when a hot layer of crude petroleum or similar liquid comes into contact with an underlying layer of a more volatile liquid and causes that liquid to flash into vapour; the expansion produced by the conversion of the entrapped liquid vapour results in a violent surface action; (débordement)

    crude petroleum

    crude petroleum is a flammable liquid with a flash point below 150°F and consisting of an unrefined mixture of natural liquid hydrocarbons as obtained from the earth; (pétrole brut)

    flammable liquid

    flammable liquid means any liquid with a flash point below 175°F, as determined by Tagliabue’s Open Cup Tester, and having a Reid vapour pressure not exceeding 40 psi absolute at 100°F or any liquid with a flash point of 175°F or above when it is heated by artificial means to a temperature not less than its flash point temperature; (liquide inflammable)

    flame arrestor

    flame arrestor is a device consisting of a group of parallel metal plates, tubes, fins or screens or a similar device with a large surface area for heat dissipation, which is designed to prevent the entrance of flame into a storage tank through a vent or similar opening; (pare-flammes)

    flash point

    flash point is the minimum temperature of a flammable liquid in degrees Fahrenheit, as determined by Tagliabue’s Open Cup Tester in accordance with A.S.T.M. Test Method: D-1310-56T at which its vapours will form a flammable mixture with air; (point éclair)

    installation

    installation means an installation of stationary bulk storage facilities for flammable liquids located on the railway right-of-way; (installation)

    main track

    main track is a track extending through yards and between stations where trains are operated by timetable, train order, block signals, or some other approved method of control; (voie principale)

    owning or operating company

    owning or operating company means the person or company owning or operating the installation; (compagnie propriétaire or exploitante)

    private track

    private track is a track outside of the carrier’s right-of-way, yard and terminals reserved exclusively for only one owner or lessee; (voie particulière)

    shall

    shall is used to indicate mandatory provisions; (le futur)

    should

    should is used to indicate recommendatory; (le conditionnel)

    station

    station means any location where passenger trains may stop in accordance with the current railway timetable; (gare)

    team track

    team track or business track is a track on railway right-of-way used by more than one company or person; (voie de desserte industrielle or voie commerciale)

    vapour pressure

    vapour pressure is the ReidFootnote * pressure, measured in pounds per square inch absolute (psia) that is exerted by a volatile liquid at a given temperature. (tension de vapeur)

    • Return to footnote  *NOTE: Standard Method of Test for Vapour Pressure of Petroleum Products (Reid Method — A.S.T.M. d 323 latest revision.)

  • (2) For the purpose of these Regulations, flammable liquids are divided into three classes:

    • (a) Class I flammable liquids includes all flammable liquids, except crude petroleum, having flash points at or below 80°F; this Class also includes Class II flammable liquids when they are heated by artificial means to temperatures not less than their flash point temperatures;

    • (b) Class II flammable liquids includes all flammable liquids, except crude petroleum, having flash points above 80°F but below 175°F; this Class also includes liquids with flash points of 175°F or above when they are heated by artificial means to temperatures not less than their flash point temperatures;

    • (c) Class III flammable liquids includes crude petroleum and any other flammable liquid with similar boil-over characteristics having a flash point below 150°F; and

    • (d) flammable liquids with a Reid vapour pressure of 40 psi or greater at 100°F are classed as compressed gases.

Application

 These Regulations apply to the stationary bulk storage facilities for flammable liquids located on the right-of-way owned or leased by any railway company subject to the jurisdiction of the Canadian Transport Commission; facilities previously approved by an order of the Commission shall be operated and maintained in accordance with these Regulations and, unless otherwise ordered by the Commission, need not conform to those parts of these Regulations pertaining to location, construction and design.

 These Regulations do not apply to a “company”, as defined in section 2 of the National Energy Board Act.
