Conditional upon the type and the location of the inboard ends of such openings, similar provisions may be prescribed by the Assigning Authority as to discharges from spaces within enclosed superstructures. Where scuppers are fitted in superstructures not fitted with Class 1 closing appliances they are to have efficient means for pre- venting the accidental admission of water below the freeboard deck. Rule XXVIII.- Side Sc'ldtles. Side scuttles to spac5S below the freeboard deck or to spaces below the superstructure deck of superstructures closed by Class 1 or Class 2 closing appliances are to be fitted with efficient inside deadlights permanently attached in their pl'oper positions so that they can be effectively closed and secured watertight. Where, however, such spaces in superstructures are appropriated to passengers other than stoerage passengers or to crew, the side scuttles may have portable deadlights stowed adjacent to the side scuttles, provided they are readily accessible at all times on service. The side scuttles and deadlights are to be of substantial and approved construction. Rule XXIX. - Guard Rails. Efficient guard rails or bulwarks are to be fitted on all exposed portions of freeboard and superstructure decks. Rule XXX.- Freeing Ports.

The mjnjmum freeing port area on each side of the ship for each well on the freeboard deck and on the raised quarter-deck is to be that given by the following scale; the minimum area for each well on any other superstructure deck is to be one-half the area given by the scale. Where the length of the well exceeds. 7 L, the scale may be modified.
