2.8 Design scenario (FI)
Design scenario in brief
Demonstrate that the level of safety be at least equivalent to the Deemed-to-Satisfy Provisions.
2.8.1 Design scenario description
The purpose of this design scenario is to describe—
the fire event the fire brigade is expected to face at its estimated time of arrival; and
the scope of available fire-fighting facilities relative to the risk to building occupant safety and adjacent buildings; and
the ability for the fire brigade to complete search and rescue activities relevant to the available firefighting activities; and
the ability of the fire brigade to control or suppress a fire.
2.8.2 Typical method or solution
This design scenario only applies to buildings located within 50 km road travel of a fire station.
Compliance with this design scenario is demonstrated via application of the Australasian Fire and Emergency Service Authorities Council’s (AFAC) Fire Brigade Intervention Model and modelling the fire and smoke development, in accordance with the CF design scenario (2.10).
Facilities for firefighting must be provided in accordance with Table 2.8, appropriate to the fire and smoke development at the estimated time of suppression activities.
