    Scope - (Show below) - (Hide below)

    This Published Document provides a framework for developing a rational methodology for design using a fire safety engineering approach through the application of scientific and engineering principles to the protection of people, property and the environment from fire. The Published Document considers the following issues: the conditions within a fire enclosure and their potential to cause fire spread; the thermal and mechanical response of the enclosure boundaries and its structure to the fire conditions; the impact of the anticipated thermal and mechanical responses on adjacent enclosures and spaces; the structural responses of loadbearing elements and their effect on structural stability, load transfer and acceptable damage according to the design and purpose of the building; fire following structural impact to the building.
