Australian Fire Engineering Guidelines abcb.gov.au Page 90 An analysis needs to be undertaken for each design fire specified by the PBDB and quantified using SS-A. Where the PBDB decision is that an analysis that includes consideration of probabilities of various events and scenarios occurring should be undertaken the flow chart can assist the FE in identifying those factors to be taken into account during the probability analysis. The flow chart provides guidance but does not necessarily cover all the factors which may be relevant to a particular fire engineering analysis. A.2.1.2 Control of smoke development and spread The control of smoke development and spread may be used to improve fire safety as an alternative (or in addition) to these measures provided by other sub-systems and those discussed in Section A.2.4.
