SAFETY OF LIFE AT SEA C39 



(2) when the number of such doors (excluding doors at entrances to shaft 



tunnels) is greater than one, but does not exceed five, 



(a) where the ship has no passenger spaces below the bulkhead 



deck, all the above mentioned doors may be hand operated 

 (Class 2); 



(b) where the ship has passenger spaces below the bulkhead deck 



all the above mentioned doors shall be power operated 

 (Class 3) and shall be capable of being simultaneously closed 

 from a central station situated on the bridge; 



(3) in any ship where there are only two such watertight doors and they 



are into or within the space containing machinery, the 

 Administration may allow these two doors to be hand operated 

 only (Class 2). 



(ii) If sliding watertight doors which have sometimes to be open at 

 sea for the purpose of trimming coal are fitted between bunkers in the between 

 decks below the bulkhead deck, these doors shall be operated by power. The 

 opening and closing of these doors shall be recorded in such log book as may 

 be prescribed by the Administration. 



(/) (i) If the Administration is satisfied that such doors are essential, 

 watertight doors of satisfactory construction may be fitted in watertight bulk- 

 heads dividing cargo between deck spaces. Such doors may be hinged, rolling 

 or sliding doors but shall not be remotely controlled. They shall be fitted at 

 the highest level and as far from the shell plating as practicable, but in no 

 case shall the outboard vertical edges be situated at a distance from the 

 shell plating which is less than one-fifth of the breadth of the ship, as defined 

 in Regulation 2 of this Chapter, such distance being measured at right angles 

 to the centre line of the ship at the level of the deepest subdivision loadline. 



(ii) Such doors shall be closed before the voyage commences and shall 

 be kept closed during navigation; and the time of opening such doors in port 

 and of closing them before the ship leaves port shall be entered in the log 

 book. Should any of the doors be accessible during the voyage, they shall be 

 fitted with a device which prevents unauthorized opening. When it is 

 proposed to fit such doors, the number and arrangements shall receive the 

 special consideration of the Administration. 



(m) Portable plates on bulkheads shall not be permitted except in 

 machinery spaces. Such plates shall always be in place before the ship leaves 

 port, and shall not be removed during navigation except in case of urgent 

 necessity. The necessary precautions shall be taken in replacing them to 

 ensure that the joints shall be watertight. 



(n) All watertight doors shall be kept closed during navigation except 

 when necessarily opened for the working of the ship, and shall always be 

 ready to be immediately closed.
