Abstract

When fire occurs in complex or building, toxic gas is important factor for evacuation because it cause death of evacuees. The effect of toxic gas which effects human motion is calculated using Purser's Fractional Effective Dose(FED). The FDS_EVAC is used for evacuation. However, FED of FDS_EVAC has some problem of application because it dose not considers evacuees's gender and age groups but using single subject. In this study, numerical analysis using modified FED which considers gender and age group of evacuees was performed. We investigate the effect of improved FED on the evacuation. We applied evacuation analysis to exhibition centre where the evacuees was set one thousand five hundred people. The FED is increasing with children 2%, male 17%, female 4%, adult 13% and elderly people 22%. Fatality is increasing due to increased FED.
