Table 25-1-1
(2). Acceptable arrangements referred to in table 25-1.1 are defined as follows:
(a) A well lighted and ventilated under-deck passageway (with a clear opening of at least 0.8 m wide and 2 m high), as close as practicable to the freeboard deck, connecting and providing access to the locations in question.
(b) A permanent and efficiently constructed gangway, fitted at or above the level of the superstructure deck, on or as near as practicable to the centre line of the ship, providing a continuous platform at least 0.6 m in width and a non-slip surface and with guard rails extending on each side throughout its length. Guard rails shall be at least 1 m high with three courses and constructed as required in regulation 25(3). A foot-stop shall be provided.
(c) A permanent walkway at least 0.6 m in width, fitted at freeboard deck level and consisting of two rows of guard rails with stanchions spaced not more than 3 m. The number of courses of rails and their spacing shall be in accordance with regulation 25(3). On type “B” ships, hatchway coamings not less than 0.6 m in height may be accepted as forming one side of the walkway, provided that two rows of guard rails are fitted between the hatchways.
(d) A wire rope lifeline not less than 10 mm in diameter, supported by stanchions not more than 10 m apart, or a single hand rail or wire rope attached to hatch coamings, continued and supported between hatchways.
(e) A permanent gangway that is: (i) located at or above the level of the superstructure deck;
(ii) located on or as near as practicable to the centre line of the ship;
(iii) located so as not to hinder easy access across the working areas of the deck;
(iv) providing a continuous platform at least 1 m in width;
(v) constructed of fire resistant and non-slip material;
(vi) fitted with guard rails extending on each side throughout its length; guard rails shall be at least 1 m high with courses as required by regulation 25(3) and supported by stanchions spaced not more than 1.5 m apart;
(vii) provided with a foot-stop on each side;
(viii) having openings, with ladders where appropriate, to and from the deck. Openings shall not be more than 40 m apart; and
(ix) having shelters set in way of the gangway at intervals not exceeding 45 m if the length of the exposed deck to be traversed exceeds 70 m. Every such shelter shall be capable of accommodating at least one person and be so constructed as to afford weather protection on the forward, port and starboard sides.
(i) located at or above the level of the superstructure deck;
(ii) located on or as near as practicable to the centre line of the ship;
(iii) located so as not to hinder easy access across the working areas of the deck;
(iv) providing a continuous platform at least 1 m in width;
(v) constructed of fire resistant and non-slip material;
(vi) fitted with guard rails extending on each side throughout its length; guard rails shall be at least 1 m high with courses as required by regulation 25(3) and supported by stanchions spaced not more than 1.5 m apart;
(vii) provided with a foot-stop on each side;
(viii) having openings, with ladders where appropriate, to and from the deck. Openings shall not be more than 40 m apart; and
(ix) having shelters set in way of the gangway at intervals not exceeding 45 m if the length of the exposed deck to be traversed exceeds 70 m. Every such shelter shall be capable of accommodating at least one person and be so constructed as to afford weather protection on the forward, port and starboard sides.
(f) A permanent walkway located at the freeboard deck level, on or as near as practicable to the centre line of the ship, having the same specifications as those for a permanent gangway listed in (e), except for foot-stops. On type “B” ships (certified for the carriage of liquids in bulk) with a combined height of hatch coaming and fitted hatch cover of not less than 1 m in height, the hatchway coamings may be accepted as forming one side of the walkway, provided that two rows of guard rails are fitted between the hatchways.
(3). Permitted transverse locations for arrangements in paragraphs (2)(c), (d) and (f) above, where appropriate:
(i) at or near the centre line of the ship; or fitted on hatchways at or near the centre line of the ship;
(ii) fitted on each side of the ship;
(iii) fitted on one side of the ship, provision being made for fitting on either side;
(iv) fitted on one side of the ship only;
(v) fitted on each side of the hatchways, as near to the centre line as practicable.
(4). (a) Where wire ropes are fitted, turnbuckles shall be provided to ensure their tautness.
(b) Where necessary for the normal operation of the ship, steel wire ropes may be accepted in lieu of guard rails.
(c) Where necessary for the normal operation of the ship, chains fitted between two fixed stanchions are acceptable in lieu of guard rails.
(d) Where stanchions are fitted, every third stanchion shall be supported by a bracket or stay.
(e) Removable or hinged stanchions shall be capable of being locked in the upright position.
(f) A means of passage over obstructions such as pipes or other fittings of a permanent nature, shall be provided.
(g) Generally, the width of the gangway or deck-level walkway should not exceed 1.5 m.
(5). For tankers less than 100 m in length, the minimum width of the gangway platform or deck-level walkway fitted in accordance with paragraphs (2)(e) or (f) above, respectively, may be reduced to 0.6 m.
