This study was conducted with the aim of identifying and prioritizing electrical factors affecting the occurrence of urban fires in the Mashhad metropolis. Considering the predominant share of fires originating from electrical current, understanding the causal structure of this category of fires can be of great help in designing safety programs and preventive strategies. This study is a descriptive-analytical study conducted using the exploratory factor analysis (EFA) method. In this study, 50,000 recorded statistical data of firefighting operations of the Mashhad Fire Department were used. Data related to the causes and origin of fires were categorized into 25 different components and 110 sample cases. The adequacy of the sample and the appropriateness of the correlation matrix in fire were confirmed with KMO=0.888 and Bartlett test χ²(300)=2314.183, p<0.001. To determine the number of factors, a combination of the criterion of eigenvalues greater than 1, scree plot were used. Exploratory factor analysis identified five main factors for the category of fires in Mashhad city, which explain a total of 70.75% of the variance. The main factor is the heat of the components of the electricity distribution network and electrical problems of electrical appliances (46.96%). This factor, which alone explains nearly 50 percent of the total variance, clearly identified electrical factors and heat in the electrical network components as the main factor in the occurrence of fires in the city of Mashhad. The most common faults include components such as connecting wires, drawing excess load from the electrical network, and sparking electrical appliances.
