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, their homes, and property. This study aims to increase the effectiveness of anomalous systems in the gas subsidiaries of Alborz province. To conduct this study, the Tripod Beta technique was used to draw a diagram of the analysis of gas accidents in homes in the Alborz province, and the 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 were 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 the Tripod Beta method, and the causes of the accidents were determined by the capability of the study method. The obstacles studied were technical safety regulations, and the creation of a safe environment. The primary reason attached to the technical safety regulations was the lack of proper understanding of valve openings and closing signs. Another immediate reason for the need to create a safe environment was the lack of safety equipment. The precondition for not understanding the open and closed sign of the valve, lack of sufficient knowledge, and the precondition for not using safety equipment, buying unsafe equipment, and the hidden reason for the lack of sufficient knowledge, lack of training, and the hidden reason for buying unsafe equipment, was the 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, the poor condition of the building, and more male residents have the most anomalies in causing gas company accidents.
