2.8 Design scenario (FI)

2.8 Design scenario (FI)

Fire brigade intervention

Design scenario in brief

This design scenario allows for fire brigade intervention.

Required outcome

Demonstrate that the fire brigade can undertake fire brigade intervention until completion of search and rescue activities; and

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—

(a)

the fire event the fire brigade is expected to face at its estimated time of arrival; and

(b)

the scope of available fire-fighting facilities relative to the risk to building occupant safety and adjacent buildings; and

(c)

the ability for the fire brigade to complete search and rescue activities relevant to the available firefighting activities; and

(d)

the ability of the fire brigade to control or suppress a fire.

Explanatory information:

Explanatory information:

This design scenario is intended to be used in conjunction with the UF design scenario (See 2.9). These two design scenarios will demonstrate that facilities for fire brigade intervention are appropriately incorporated.

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.
