(2) Stairways must be distributed in such a manner as to ensure ease of exit to the weather deck for all occupants of the various spaces. If the surveyor is doubtful as to the efficiency of the arrangements the case should be referred to the Principal Surveyor of Ships for instructions.
(3) Separate stairways are to be provided for each passenger compartment or space, and in no case may the only means of communication with any such compartment or space consist of openings in bulkheads which form part of the sub- division arrangements of the ship unless these openings are trunked watertight to the bulkhead deek and are otherwise approved by the Principal Surveyor of Ships.
(4) The aggregate width of the stairways from each pas- senger space is to be not less than one inch for every four persons accommodated therein. Provided that where stair- ways afford access to the weather deck for passengers accom- modated in two spaces, one above the other, the stairways from the upper space to the weather deck are to have an aggregate width of at least one inch for every four persons in the space which accommodates the larger number with the addition thereto of one inch for every five persons in the remaining space.
(5) Where the stairways from any unberthed passenger compartment or compartments to the weather deck are led into a poop, bridge, forecastle or other similar erection, the aggregate width of the openings in the bulkheads forming the ends of such superstructures is to be not less than the width required for the said stairways with the addition thereto of one inch for every 5 persons accommodated in the superstruc- ture who are intended to use such means of exit.
Where doorways serve a superstructure or deckhouse exclusively, the aggregate width of the clear opening is to he not less than one inch for every 4 persons accommodated therein who are intended to use such means of exit. The clear opening of doorways is not to be less than 30 inches in width.
(6) The stairways from unberthed passenger accommoda- tion are to lead directly to a space on the weather deck which is at all times accessible to such passengers.
Arrangements by which access to the weather deck is by stairways leading into spaces not intended for unberthed pas- sengers are not to be accepted unless full particulars with plans of the proposed arrangement have been submitted and approv- ed by the Principal Surveyor of Ships. Such stairways can in no case be accepted if fitted with doors having locking arrangements outside the unberthed passenger compartments.
No
(7) No stairway is to be less than 30 inches in width. stairway is to be more than 60 inches in width unless fitted with intermediate rails which are to be not less than 30 inches or more than 60 inches apart.
The width of all stairways is to be measured on the tread and within the sides, unless the handrails encroach on the tread, in which case the distance between the rails is to be taken as the width.
(8) All stairways are to be properly secured, sparred on the back and fitted with handrails (not ropes) on each side.
