摘要:This article is to identify and visualize the territory of St. Petersburg, which is not included in the service area of fire departments. The article provides an analysis of standards and the calculation of the maximum distance from the fire department to the object of the alleged fire. As a result of the calculation, it cleared up that the maximum service radius of one fire department is 2.5 km. A map was also made showing the service radii of fire stations in St. Petersburg. The authors represented zones that do not fall within the radii, and suggested possible solutions to certain problems.
