Major industrial accidents, which are a type of technological disaster, are very important due to the security risks and financial damages that threaten the environment and human health in today's industrialization. In this study, it was aimed to propose an approach that will guide the decision makers to choose the emergency assembly point that should be in the distance or shelter where the employees will be not affected by the negative consequences of emergencies within the scope of the obligation of industrial establishments preparing an internal emergency plan for major industrial accidents. For this purpose, in the first stage, modelling studies were carried out with ALOHA (Areal Locations of Hazardous Atmospheres) Software over possible accident scenarios in an industrial establishment containing different types and amounts of hazardous chemicals. As a result of modelling studies, possible toxic emissions, fire and explosion effect distances and threat zones for the industrial establishment were obtained. In the second stage, the weights of the main and sub-selection criteria to be used in determining the assembly point were calculated. This stage was carried out based on the comparison data obtained as a result of the questionnaire applied to professionals with the help of AHP (Analytic Hierarchy Process) method, which is one of the multi-criteria decision making methods. In the last stage, three candidate points were selected considering the physical effect areas determined in the first stage in the boundaries of the establishment, where the employees were evaluated to be affected the minimum from the negative consequences of industrial accidents. These candidate points were evaluated again with the AHP method on the basis of the sub-criteria whose relative weights were determined in the second stage and a selection was made. As a result, an approach that provides the solution of our problem was obtained.
