48 (1) When the carrier’s track is a team or business track, it is recommended, when practicable, that Class I flammable liquid tank cars be protected during loading or unloading operations by a locked derail or switch located at least one car length from the tank car on the connected end or ends of such team or business track.
(2) The loading or unloading of Class I flammable liquids from the bottom outlet of a tank car located on a team or business track is not permitted unless specifically requested by the applicant and approved by the Commission. Bottom unloading is prohibited less than 25 feet from the main track.
(3) The procedure for loading or unloading tank cars as detailed in section 74.561 of the Regulations for the Transportation of Dangerous Commodities by Rail shall be followed.
49 (1) The installation site shall be free of debris or other combustible material, and grass and weed growth shall not be permitted to exceed six inches.
(2) No combustible or dangerous commodities other than those sanctioned by the approving order shall be stored on the installation site.
50 Defective piping, valves or fittings shall be repaired or replaced immediately.
51 Smoking and the use of portable open flame lights or equipment is prohibited, except in isolated, clearly designated safe areas. Signs to this effect shall be posted at plant entrances, storage tanks, loading and unloading sites.
52 Welding is prohibited within 100 feet of a Class I flammable liquid or a crude petroleum loading or unloading site while loading or unloading operations are in progress. At other times, welding may be permitted only under close supervision and in accordance with the provisions of Canadian Standards Association Pamphlet W-117-1952 or subsequent edition.
53 (1) Dry powder, carbon dioxide, or other fire extinguishers suitable for small flammable liquid fires shall be readily available on the premises of every flammable liquid installation. Extinguishers subject to freezing shall be adequately protected. At least one fire extinguisher should be maintained on the outside premises.
(2) It is recommended that all flammable liquid installations be protected by at least one standard fire hydrant so located that a 2 1/2-inch hose stream may be used for controlling a fire on the site, or for cooling storage tanks in case of adjacent fires. Consultation with the local fire authority is recommended.
54 (1) Except as provided in section 17, all electrical equipment and facilities located out-of-doors within 25 feet of a storage tank, loading, unloading rack or terminal, pump or pumphouse used for Class I flammable liquids or crude petroleum shall comply with the requirements of the Canadian Electrical Code for Class I, Division II, Group D hazardous locations.
(2) Except as provided in section 41, all electrical equipment and facilities located inside a pumphouse, warehouse or other building where any flammable liquid is dispensed, processed or otherwise exposed to evaporation, leakage or spillage, or where Class I flammable liquids are stored or handled shall comply with the requirements of the Canadian Electrical Code for Class I, Division I, Group D hazardous locations.
(3) All electrical equipment and facilities used in environments where explosion proof equipment and facilities are prescribed in this section shall be approved for Class I, Division I, Group D hazardous locations and shall be so marked or labelled by the manufacturer.
55 (1) It is recommended that every flammable liquid bulk storage installation be completely enclosed within a steel mesh fence not less than five feet in height. The mesh shall be made from steel wire of not less than 0.10 inch diameter. The mesh openings shall not be greater than six inches. The fence should be provided with at least two gates. Each gate shall be equipped with a lock.
(2) If the installation is not fenced, then all storage tank shut-off valves shall be locked in the fully closed position when the plant is unattended. (Valves shall not be locked in an open position).
56 Stairs, platforms and walkways should be constructed of metal, concrete or some other non-combustible material.
57 (1) Storage tanks installed on ground which drains toward railway tracks, rights-of-way, adjacent waters, sewers, or congested areas shall be protected by suitable dikes.
(2) Storage tanks containing crude petroleum shall be diked where railway or adjacent private property would be exposed in the event of a boil-over of the liquid.
(3) Dikes for Class I or Class II liquids shall have a net capacity not less than the capacity of the largest storage tank plus 10 per cent of the aggregate capacity of all other storage tanks in the diked area.
(4) Dikes for crude petroleum shall have a net capacity not less than the capacity of all the storage tanks in the diked area. The dikes shall be provided with flareback sections at the top of the dike designed to turn back a boil-over wave. These flareback sections shall not be required for dikes enclosing approved floating roof storage tanks, or when storage tanks are provided with approved attached extinguishing systems.
(5) No dike enclosing crude petroleum storage tanks shall include storage tanks containing Class I or Class II flammable liquids.
(6) Provision may be made for draining water from diked areas if the area where the piping passes through the dikes is protected from seepage by flanges or other suitable means.
58 The drainage of dikes, tanks, pipelines, etc. containing flammable liquids or flammable liquid residues into lakes, streams, storm sewers or sanitary sewers is prohibited.
59 (1) In the spring of each year after the ground has completely thawed, the owning or operating company shall test for leakage by subjecting all marine dock pipelines on carrier’s property to a pressure test of 50 per cent in excess of the maximum working pressure.
