An anomaly is an unsafe condition or action that has the potential to cause an accident. These conditions or unsafe practices in gas companies play a very important role in the occurrence of gas leaks and fires. Any unsafe acts can lead to unpleasant incidents for citizens and their homes and property. The aim of this study is to increase the effectiveness of anomalous systems in gas subsidiaries of Alborz province. To conduct this study, Tripod Beta technique to draw a diagram of analysis of gas accidents in homes in Alborz province and hierarchical analysis method was used to assess the risk of injuries, casualties and unintentional house fires. In the first stage, information on gas leaks and fires was collected by reviewing the documents related to the winter events of 2020. Then the sum of the mentioned conditions was studied as a hypothetical model. In the second step, the mentioned model was analyzed using Tripod Beta method and the causes of the accident were determined by the capability of the study method. The obstacles studied were technical safety regulations and the creation of a safe environment. The immediate reason attached to the technical safety regulations was the lack of proper understanding of the valve opening and closing sign. Another immediate reason for creating a safe environment was the lack of safe equipment. The precondition for not understanding the open and closed sign of the valve, lack of sufficient knowledge and the precondition for not using safe equipment, buying unsafe equipment and the hidden reason for lack of sufficient knowledge, lack of training and the hidden reason for buying unsafe equipment was poor economic situation. The results of this study indicated that fire-related conditions are of the utmost importance in assessing the risk of unintentional house fires. Failure to pay attention to safety points while using gas-related equipment, poor condition of the building and more male residents have the most anomalies in causing gas company accidents.
