A Petri-net approach for firefighting force allocation analysis of fire emergency response with backups

Fire is one of the main accident scenarios occurring in chemical and process plants, it can lead to domino effects due thermal radiation. Emergency response necessary prevent fire escalation, addition safety barriers. In major industrial accidents, backup usually required emergency response, lack capacity a single department. A method addressing optimal allocation forces, specifically considering front-line departments, developed present study. The departments reduce radiation received by equipment adjacent primary thus prolong time failure equipment, such that backups have more get scene. analysis teams carried out dynamic ttf an item resulting from change received. timed colored hybrid Petri-net (TCHPN) approach proposed model process. probability preventing escalation obtained TCHPN firefighting forces determined. case study illustrates approach, two are compared results show if request for be issued immediately according state, fewer deployed on front line department, as reduction 6 3 maintain success 0.91. influence other factors position layout tanks also discussed.
