Restricting fire spread within buildings
Fire spread within a building can be restricted through ensuring minimum fire resistance standards for structural elements, subdividing the building into fire-resisting compartments, subdividing cavities, and protecting openings and penetrations through fire-resisting construction.
The spread of fire within a building can be restricted by –
(a) ensuring the elements of structure and certain other components of the building have a minimum standard of fire resistance;
(b) subdividing the building into compartments with fire-resisting construction;
(c) subdividing concealed and extensive cavities within the construction; and
(d) protecting openings in, and penetrations through, fire-resisting construction.
Where a building is divided into separated parts by a compartment wall (or walls), running the full height of the building in a continuous vertical plane, the provisions of this Section may be applied separately to each separated part.
