Study On Railway Station's Fire Safety Evacuation And Prevcaution Measures

Railway station is a large space, with so many passengers and station staffs. It has complex evacuation routes. And the passengers carried a large amount of luggage. It is a place which catches fire easily. Therefore, it is very useful for studying railway station's fire emergency evacuation.Since the 50 years of last century, many scientists have studied many models of fire emergency evacuation. These models can be classified into three types as follows: Network Model which ignores the difference of Person, Griddling Model which considers the different characteristic of Person, and the Network Griddling Model which has the ability to model the change of Person's position in a flexible way and the characteristic of person. These models provide many good measures for fire emergency evacuation.This paper analyzed the problems when train station on fire, using security science, behavioral science, sociology's theory and methods, such as overcrowding, trampling and the arching clusters flow phenomena through data collection and reading the large number of domestic and foreign literature integrated with fire emergency evacuation case of ordinary railway station. Discussion the future challenges of new comprehensive stations on the safe evacuation.The people were divided into two categories station staff and the passengers according to their roles. It draws station staff's fire emergency evacuation operation network through studying the station's fire emergency plan with station daily regulations. This paper described the passenger's evacuation process using Colored Petri Net based on the passenger's behavior, integrated with psychological, physiological and social behavior.This paper stated basic conditions for passenger safety evacuation in train station fire and analyzed the composition of passenger evacuation time. Then this paper established static and dynamic networks according to the passenger's evacuation lines to calculate the evacuation time. At last, we compare the evacuation time based on different strategies and different passengers.We analyzed the subjective and objective reasons of Nanjing station's fire through studying Nanjing station's fire process and the serious outcome. Then we descript the failure evacuation process using Petri net. At last, we established the station evacuation failure's fault tree and calculated the minimum cut sets and most trails set. And the basic events are sorted according the structure importance. According the structure importance of the basic events, we provide some measures for preventing station fire and evacuation efficiently.
