82.3 (1) Where any cargo ports and other access openings above the bulkhead deck are located
(a) in the ship’s side, or
(b) at an exposed location on an enclosure and the enclosure protects any openings in the bulkhead deck that are not fitted with weathertight closing appliances,
the number of such cargo ports and other access openings shall be the minimum compatible with the design and proper working of the ship and each such opening shall be fitted with approved closing appliances so constructed as to maintain the structural and weathertight integrity of the ship’s side or that enclosure.
(2) Every opening referred to in subsection (1) that is located in the first tier of superstructures above the bulkhead deck and that has a clear opening of more than 1.5 m2 shall be provided with a sensing device that will activate a green indicator light located in the wheelhouse, which light remains continuously lit as long as the closing appliance with which the opening is fitted is closed and effectively secured.
- SOR/81-86, s. 2.
82.4 (1) Every closing appliance required by section 82.2 or 82.3 shall be designed to open outwards and shall be provided with positive structural support against external pressure.
(2) A power available indicating device shall be provided to confirm the operational readiness of every sensing or indicating device required by section 82.2 or 82.3.
(3) Every sensing device and every indicating device required by section 82.2 or 82.3 shall be tested at intervals no greater than the intervals between each boat and fire drill and the master shall ensure that the particulars of each test are entered in the ship’s log.
(4) Notwithstanding the arrangements required by sections 82.2 and 82.3 and subsections (1) to (3) of this section, alternative arrangements may be made if such alternative arrangements are at least as effective as the arrangements so required.

83. The requirements for fuel oil tanks that do not form an integral part of the ship’s structure and have a capacity of more than 4 500 L are as follows:
(a) the outside plating shall be fitted with stiffeners so that the area of the unsupported flat surface of a plate whose thickness is set out in column I of an item of the table to this section does not exceed the area set out in column II of the item;
(b) the following shall be fitted to each tank, namely,
(i) wash plates, if required,
(ii) doublers or striking plates, under all sounding pipes,
(iii) in the case of riveted construction, drip trays, and
(iv) manholes whose covers are secured by 16-mm studs spaced apart at a distance of 70 mm or less, centre to centre;
(c) if drains are fitted, they shall be of the weighted-lever or other self-closing type;
(d) every air pipe to a tank shall
(i) be carried well above deck,
(ii) have an outlet that is
(A) in a safe location, and
(B) fitted with readily removable wire-gauze screens, the total area of clear opening of the screens being not less than the cross-sectional area of the air pipe, and
(iii) have a net area that
(A) in the case of a tank that can be filled by the ship’s pumps or by shore pumps, is greater than the effective area of the corresponding filling pipe by at least 25 per cent; and
(B) in any other case, is at least equal to the effective area of the corresponding filling pipe; and
(e) on completion of its fitting, every tank shall be tested in the presence of a steamship inspector by filling it with water to a head that is equal to the maximum head to which the tank will be subjected or a head of 2.44 m above the tank crown, whichever is greater.
