- SOR/85-470, s. 1.
12 Except as provided in sections 13 and 14, the horizontal distance between a storage facility and the nearest point of another building, structure or property line, should not be less than
(a) 300 feet from any school, hospital, hotel, motel, church, theatre, auditorium, sports arena, multi-store shopping centre, apartment or other similar multi-unit residential building, office building or department store or merchandise building of more than one storey in height or any other similar structure used for assembly, institutional, residential, business, personal service, or mercantile purposes, or any building considered by the Commission to belong to this category;
(b) 150 feet from a single family dwelling, railway passenger station, railway station-dwelling, office building or department store or merchandise building or restaurant of one storey in height, or any other similar structure used for housing, business, personal service, or mercantile purposes, or any other building considered by the Commission to belong to this category;
(c) 100 feet from any factory, railway shop or other building used primarily for manufacturing, processing or for maintenance or repair work, or from an adjoining office building associated with these buildings, except that this distance should not be less than 50 feet if the capacity of the storage facility does not exceed 200 tons;
(d) 100 feet from any railway freight station, warehouse, storage tank or any other storage or transfer facility used for a combustible or dangerous commodity or from an adjoining office building associated with these buildings, except that this distance should not be less than 50 feet if the capacity of the storage facility does not exceed 200 tons;
(e) the following distances from the nearest point of the line of an adjoining property which has been or may be built upon and which is owned or leased by any person or company other than the owner of the storage facility:
(i) not less than 25 feet if the capacity of the storage facility does not exceed 200 tons,
(ii) not less than 50 feet if the capacity of the storage facility exceeds 200 tons, unless it is constructed of non-combustible materials as provided for by subparagraph (iii) or the adjoining property is occupied by another ammonium nitrate storage facility as provided for by subparagraph (iv),
(iii) not less than 25 feet if the storage facility referred to in subparagraph (ii) is of non-combustible construction and has a fire separation of not less than 1 1/2 hours on the exposed side,
(iv) not less than 25 feet if the property adjoining the property referred to in subparagraph (ii) is occupied by another ammonium nitrate storage facility approved in accordance with these Regulations and if there are no other buildings between the two storage facilities;
(f) 20 feet from the gauge side of the nearest rail of a main track or any track other than a track serving the storage facility; and
(g) the distances prescribed in Schedule I from the gauge side of the nearest rail of the track serving the storage facility.
13 Notwithstanding section 12, greater safety distances may be imposed on storage facilities located within densely populated areas or other areas considered by the Commission to be of special hazard.
14 (1) Notwithstanding section 12, and except as provided in subsection (2), the horizontal distance between a storage facility not exceeding a capacity of 200 tons and another on-site structure which is used only for storage purposes and which does not contain a dangerous commodity should not be less than 10 feet.
(2) Notwithstanding section 12 and subsection (1), lesser distances may be authorized at the discretion of the Commission between a storage facility and other on-site structures.
PART IIIDesign and Construction of Storage Facilities
15 Unless specifically approved by an Order of the Commission,
(a) a storage facility shall not be more than one storey in height, except as may be necessary to house an elevator or similar equipment, and it shall not be erected over a basement;
(b) bulk storage bins shall not exceed 40 feet in height, unless they are constructed of non-combustible material.
(2) If the floor or any other part of a storage facility in contact with ammonium nitrate or ammonium nitrate mixed fertilizer is fabricated from a combustible material, it shall be protected against ammonium nitrate impregnation by a plastic sheet or a suitable coating such as polyurethane or epoxy paint.
(3) Parts of a storage facility in contact with ammonium nitrate and fabricated from metal such as zinc, lead, copper or other metal, which will react with ammonium nitrate, shall be protected by a suitable coating.
17 (1) Except as provided in subsections (2) to (4), the floor of a storage facility shall not contain drains, traps, pits or other depressions in which molten ammonium nitrate may become confined in the event of a fire.
(2) Notwithstanding subsection (1), elevator pits and conveyor trenches may be installed in the floor of a storage facility if molten ammonium nitrate is prevented from flowing into them by curbs or other construction features acceptable to the Commission, or there are extenuating circumstances that, in the opinion of the Commission, justify or minimize the hazard of an opening in the floor.
(3) Ammonium nitrate or mixed fertilizers containing 60 per cent or more ammonium nitrate shall not be stored in bins or piles that are contiguous to an elevator pit or conveyor trench where it is practical to store them in a location separated from the floor openings referred to in subsection (1) by bins or piles containing non-combustible and non-hazardous materials.
(4) Trenches shall not be constructed under railway tracks unless approval to do so has been obtained from the Commission. Applications for this approval shall be submitted through the railway company concerned.
18 All storage facilities, except those that are self-ventilating under fire conditions, shall be ventilated with permanently open ventilators to assist in the dissipation of the heat and gases produced by the decomposition of ammonium nitrate in a fire.
19 (1) Except as provided in subsection (2), all electrical wiring, lighting or equipment inside a storage facility or attached to it shall comply with the requirements of the Canadian Electrical Code, (CSA Standard C22.1 — 1962 and amendments thereto), as prescribed for ordinary locations. A storage facility containing bagged ammonium nitrate or ammonium nitrate mixed fertilizer and no other electrical hazard is designated an “ordinary location”.
(2) All parts of an electrical system not installed in ordinary locations shall comply with those requirements of the Canadian Electrical Code applicable to the particular hazards present. A storage facility containing bulk ammonium nitrate or ammonium nitrate mixed fertilizer and no other electrical hazard is designated a Class II Division II location.
20 The design, construction and maintenance of a storage facility shall be such as to prevent the normal ingress of rain and ground water.
(2) Notwithstanding subsection (1), welding or cutting repairs may be made inside a storage facility to metal equipment or components of the storage facility if the broken part cannot be removed for repair out-of-doors and the following precautions are taken:
(a) all ammonium nitrate and other dangerous or combustible materials stored within 10 feet of the repair site shall be removed;
(b) the welding or cutting operation shall be completely screened to prevent sparks from leaving the enclosed clean area and if the floor in this area is constructed of wood or other combustible material, its exposed surface shall be drenched with water or protected against sparks by a flame-proof tarpaulin or a metal sheet;
(c) a fire extinguisher as prescribed in section 24 and a water hose, or a static supply of not less than 45 gallons of water, shall be available at the repair site; and
(d) the operation shall be under the supervision of a qualified and responsible person who shall remain at the repair site for at least 30 minutes after the completion of repair operations.
(3) If it is necessary to heat a storage facility, it is recommended that the heat be supplied by an electric heater which complies with section 19 or by low pressure steam, hot water or other enclosed heat transfer media with the heat source located in a detached building at least 10 feet from the storage facility, and heating systems which do not comply with this recommendation shall be approved by the Commission.
(4) Heating equipment shall be designed and installed in accordance with the National Building Code of Canada, except that no part of the equipment with an open flame or other source of ignition shall be installed in the storage area.
