• (a) all linings, grounds, ceilings and insulation shall consist of incombustible material except in cargo spaces, mail rooms, bullion rooms, baggage rooms and refrigerated store rooms, provided that the linings, grounds and ceilings in ships carrying not more than 100 passengers may be constructed of combustible material having the same fire-resisting properties as the material of the bulkheads enclosing the spaces in which they are situated; and

• (b) the total volume of combustible materials installed as facings, mouldings, decorations or veneers in any accommodation space or service space in a ship in which Method I of fire protection has been adopted, being a ship carrying more than 100 passengers, shall not exceed a volume equal to that of veneer of 2.5 mm on the combined area of the walls and ceiling of such space; any facings, mouldings, decorations or veneers installed in the corridors or stairway enclosures in such a ship shall consist of incombustible materials.

(2) In every ship in which Method III of fire protection has been adopted, the provision of combustible materials for linings, grounds, ceilings, fittings and furnishings in any space in the accommodation spaces or service spaces shall be restricted to the minimum compatible with the use for which that space is appropriated; in the public rooms in such a ship the grounds and supports for the linings and ceilings shall be constructed of steel or other material equally effective in resisting fire; all exposed surfaces and their coatings in the accommodation spaces of such a ship shall be surfaces of low flame spread.
