Australian Fire Engineering Guidelines abcb.gov.au Page 122 A.5.1.2 Control of occupant evacuation The control of occupant evacuation may be used to improve fire safety as an alternative (or in addition) to those measures provided by other sub-systems, and these are discussed in Section A.5.4.2. A.5.2 Outputs – SS-E Depending on the analysis tools used, the following parameters are generally available as outputs from SS-E:
cue period (P c ). This is the period from fire initiation to the occurrence of a selected cue.
response period (P r ). The occupants may not immediately associate the cue available to them with a fire-related emergency. The PBDB should have set the
delay period (P d ). The occupants may carry out a wide variety of delay-causing actions (including ‘no action’) once they have recognised the fire cues (and
movement (travel) period (P m ). The time span between the initiation and completion of the movement to a place of safety is referred to as the movement
RSET. The sum of the cue period, response period, delay period and movement period is known as the RSET. This time is used in the collation of the A.5.3 Inputs – SS-E The required input parameters to SS-E are determined by the analysis methods used. They may include:
Building characteristics. These should be available from the PBDB. Relevant parameters may include:
building type and use
