In this study, it was focused on the selection of software for identifying the physical effect distances of the explosion, fire and toxic emission, which is an important need for industrial institutions containing, using or storing hazardous chemicals. The evaluation and selection of software for the Hazard Analysis and Consequence Modeling (HACM) of potential accidents was studied at first. In means of methodology, questionnaires consisting of original questions were applied to the experts. The results obtained from questionnaires according to the Likert scale, were converted into Analytical Hierarchy Process (AHP) suggestion matrices. In this way the inconsistency problem in the pairwise comparison matrices were eliminated. As a result, evaluation and selection were made among the HACM softwares.
