SAFETY OF LIFE AT SEA ^-'-' 



(b) (i) Steps and recesses in bulkheads shall be watertight and as strong 

 as the bulkhead at the place where each occurs. 



(ii) Where frames or beams pass through a watertight deck or bulk- 

 head, such deck or bulkhead shall be made structurally watertight without 

 the use of wood or cement. 



(c) Testing main compartments by filling them with water is not com- 

 pulsory. When testing by filling with water is not carried out, a hose test 

 is compulsory; this test shall be carried out in the most advanced stage of 

 the fitting out of the ship. In any case, a thorough inspection of the water- 

 tight bulkheads shall be carried out. 



(d) The forepeak, double bottoms (including duct keels) and iimer skins 

 shall be tested with water to a head corresponding to the requirements of 

 paragraph (a) of this Regulation. 



(e) Tanks which are intended to hold liquids, and which form part of 

 the subdivision of the ship, shall be tested for tightness with water to a head 

 tip to the deepest subdivision loadline or to a head corresponding to two- 

 thirds of the depth from the top of keel to the margin line in way of the 

 tanks, whichever is the greater; provided that in no case shall the test head 

 be less than 3 feet (or • 92 metres) above the top of the tank. 



(/) The tests referred to in paragraphs (d) and {e) of this Regulation are 

 for the purpose of ensuring that the subdivision structural arrangements are 

 watertight and are not to be regarded as a test of the fitness of any compart- 

 ment for the storage of oil fuel or for other special purposes for which a test 

 of a superior character may be required depending on the height to which 

 the liquid has access in the tank or its connections. 



Regulation 13 



Openings in Watertight Bulkheads 



(a) The number of openings in watertight bulkheads shall be reduced to 

 the minimum compatible with the design and proper working of the ship; 

 satisfactory means shall be provided for closing these openings. 



(b) (i) Where pipes, scuppers, electric cables, &c., are carried through 

 watertight subdivision bulkheads, arrangements shall be made to ensure the 

 integrity of the watertightness of the bulkheads. 



(ii) Valves and cocks not forming part of a piping system shall not 

 be permitted in watertight subdivision bulkheads. 



(iii) Lead or other heat sensitive materials shall not be used in systems 

 which penetrate watertight subdivision bulkheads, where deterioration of such 

 systems in the event of fire would impair the watertight integrity of the 

 bulkheads.
