Many countries have experienced a lot of loss of life and material losses in many incidents due to natural or technological disasters. Planned and systematic action is required to manage emergencies. For this, a successful plan must be prepared. In order for the emergency management to be successful, it is necessary to successfully evacuate people from the building in the event of a disaster. Emergency evacuation plans, evacuation drills and training should be provided. Simulations and models have often been one of the methods people use to study events. How solutions should be created for the events encountered were examined with simulations. With emergency evacuation simulations, an emergency management plan can be made close to reality. This study was carried out in a university building. In this 3-storey building, there are students, lecturers and working personnel. The best emergency evacuation plan to be applied in an emergency has been researched. It was aimed to create a plan with the shortest evacuation time by making experiments with the simulation program. Pathfinder simulation program was used in this study. In the first part, 11 scenarios related to the routing variability to the emergency exit doors were created. It is aimed to create a plan with the best evacuation time. In the second part, 5 scenarios were created about the situations where the emergency exit doors are locked and the doors are unusable for certain periods. The effects of these disruptions on the evacuation period were examined.
