Fire safety is one of the essential requirements for a building, and the safety of people that are affected by the fire is the priority. Fire and its products such as smoke, poisonous gases and flames threathen human lives in a matter of minutes therefore it is essential to predict an appropriate and timely evacuation and eliminate any potential factor that could decrese its effectiveness. The purpose of this paper is to analyse the time needed to evacuate a parked airplane connected to the airbridge while at the same time there is a fuel spill fire. The analysis is made in the software “Pathfinder”. For the purpose of this paper the airbridge on the airport “Franjo Tuđman” in Zagreb and the airplane Airbus A320 are considered. Because of the fuel characteristics and fuel spill fire characteristics not all emergency exits can be used and therefore the evacuation must go through the airbridge until people reach a safe distance from the fuel spill fire area. The increase in the number of passengers and the demand for a greater number of airplane seats has resulted in a decrease in available space in the cabin, therefore it raises a question, are the passengers in this environment during the evacuation safe. The results from the software suggest that the evacuation is possible in a time less than five minutes if the passengers respond immediately to the clueus that are given by the airplane staff and if they follow them strictly. It is also noteworthy to mention that the American standard NFPA 415 used to construct the airbridge at the Zagreb airport demands the minimum fire resistance and smoke resistance of five minutes which in turn means that those aribridges meet the requirements. If the passengers don’t follow the clues and instructions of the staff, the time of the evacuation increases considerably.
