It shall also include staff rooms, locker rooms, and general purpose offices. 2.1.2.4 Area of Station (a) The area of any storey of a station or compartment shall be taken to be the total area of that storey bounded by the inner finished surfaces of the enclosing walls or, on any side where there is no enclosing walls, by the outermost edge of the floor on that side. (b) The area of any room or space shall be taken to be the total area of its floor bounded by the inner finished surfaces of the walls forming the room or space. (c) The area of any part of a roof shall be taken to be the actual visible area of such part measured on a plane parallel to the pitch of the roof.

2.1.2.5 Area of Refuge (a) In the station under consideration, an area of refuge is an area adequately separated from the rest of the station by fire resisting construction (see Section 2.3 for details), and evacuees from the rest of the station enter the area of refuge using an external corridor that links this area to the rest of the station. An area of refuge may serve as required exit in lieu of the provisions given under Cl.2.1.2.27. (b) An area of refuge may also be an area in an adjoining station which is separated from the station under consideration by fire resisting construction and evacuees similarly enter this area of refuge using an external corridor. (c) An area of refuge shall always be accessible. 2.1.2.6 An atrium within a station is a large open space created by an opening, or a series of openings, in floor assemblies, thus connecting two or more storeys. Atrium is covered at the top and is used for purposes other than those associated with small shafts, such as for stairs, elevators and various services. The sides of the atrium may be open to all floors, to some of the floors or closed to all or some floors by nonrated or rated fire-resistance construction. 2.1.2.7 Backlayering means the reversal of movement of smoke and hot gases counter to the direction of the ventilation airflow. Area of refuge Atrium Backlayering 2.1.2.8 Basement Storey Basement storey (a) A storey of a station which is below the first storey and the floor of which is situated at such a level that more than half the height of such storey is below the level of the ground adjoining its perimeter walls for more than half the length of such perimeter walls, and (b) Where the station has no storey above ground, a storey the floor of which is situated at such a level that either the whole storey is below ground or more than half the height of such storey is below the level of the ground adjoining its perimeter walls for more than half the length of such perimeter walls.
