2.3.1 GENERAL SECTION 2.3 STATION STRUCTURAL FIRE PRECAUTIONS 2.3.1.1 The purpose of this section of the Standard is to stipulate requirements to minimise the risk of spread of fire between adjoining stations/buildings by separation, prevent the untimely collapse of stations in the event of fire by the provision of a stable and durable form of construction and prevent the spread of fire between specified parts of the stations by the division of such stations into compartments. 2.3.2 PROVISION OF COMPARTMENT WALLS AND COMPARTMENT FLOORS 2.3.2.1 Any station which has: (a) Any storey the floor area of which exceeds that specified as relevant to a station of that height in column (2) of Table 2.3.2A, or (b) A cubic capacity which exceeds that specified as so relevant in column (3) of Table 2.3.2A, shall be divided into compartments by means of compartment walls and compartment floors so that - (i) No such compartment has any storey the floor area of which exceeds the area specified as relevant to the station in column (2) of the Table, and (ii) No such compartment has a cubic capacity which exceeds that specified as relevant in column (3) of the Table. Exception: Size limitation of compartment shall not apply to the public area below ground level. Compartment size for public area below ground level shall comply with Cl. 2.3.2.4(e).
