The aim of this study was to develop a crisis management conceptual model in sports events based on thematic analysis. The present study was conducted within the framework of a qualitative approach and the required data were collected using semi-structured interviews. The population included all individuals and experts in the field of crisis management exercise, including sports management professors, experts and specialists in the departments of Youth and Sports was crisis management force. Purposeful sampling method was continued with snowball technique until theoretical saturation was achieved. In thematic analysis, the data obtained from deep and semi-structured interviews with experts were coded. Then, in two stages, the initial concepts were produced, in the first stage, 56 concepts were extracted from interviews with experts. These concepts in the second stage, for greater coherence and better analysis and interpretation in the form of 12 more abstract concepts under the headings of socio-cultural factors, financial factors, human resource organization, education, equipment, facilities, management factors, public relations, public relations, health And safety, productivity, human resource promotion were coded.

In recent years, due to the occurrence of numerous incidents such as fire and explosion in Tehran Oil Refinery and the importance of this refinery in supplying fuel needed in Tehran has been selected as a case study. The purpose of this study is to use a new method of outcome analysis to model the consequences of release, release, fire or combustion in the benzene storage tank in Tehran Oil Refinery. The type of research or attention to the purpose of research is applied. The research method is scenario modeling in terms of implementation. Data related to meteorology of the region (temperature, wind speed, relative humidity and cloud cover) were obtained from the site of the Meteorological Organization. Also, information about the geometry of the reservoirs was obtained from the processes in the Tehran oil refinery. The data analysis method was performed using ALOHA modeling software. The mean and maximum daily temperature scenarios were considered in the threat zone release. The results of fire outcome modeling showed that there is a direct relationship between the stability of the atmosphere, the volume of chemicals in the reservoir and the size of the leak with increasing the area of the threat zone in the refinery. According to the results obtained in the first scenario, the highest risk in the first zone starts up to a distance of 94 meters and continues up to 207 meters in the third zone
