34.—(1) (a) Where pipes, scuppers, electric cables, etc., are carried through watertight subdivision bulkheads, arrangements shall be made to ensure the integrity of the watertightness of the bulkheads.
(b)
Only a valve or cock forming part of a piping system shall be permitted in a watertight subdivision bulkhead.
(c)
Lead or other heat sensitive material shall not be used in a system which penetrates any watertight subdivision bulkhead, where deterioration of such system in the event of fire would impair the watertight integrity of the bulkhead.
(2) Collision bulkheads shall not be pierced below the margin line by more than one pipe. Any pipe which pierces the collision bulkhead shall be fitted with a screwdown valve capable of being operated from above the bulkhead deck, the valve chest being secured inside the forepeak.
(3) Efficient means shall be provided for closing all openings in watertight bulkheads. Details of the means provided for closing these openings shall be submitted to the Director for approval.
