This article analyzes the determination of the limiting conditions of the gorenje process in buildings and structures. All combustible substances contain carbon and hydrogen– which are the main components of the gas-air mixture involved in the gorenje reaction. The ignition temperature of combustible substances and materials is different and does not exceed 300°C for most. The analysis showed that the process of fire occurrence should be taken into account in cases where the possibility of spontaneous ignition or spontaneous combustion is being investigated. The latter can sometimes occur due to prolonged exposure to heat at a relatively low temperature and cause fires. Ignition is the process of spreading a flame through a gas-air mixture. At the rate of the outflow of combustible vapors and gases from the surface of the substance equal to the speed of flame propagation through them, a steady flame gorenje is observed. If the flame velocity is greater than the velocity of vapors and gases, then the combustion of the gas-vapor mixture and selfextinguishing of the flame occurs. Ignition sources are a necessary condition for ignition of a combustible mixture. Ignition sources are divided into open fire, heat of heating elements and appliances, electrical energy, energy of mechanical sparks, static electricity and lightning discharges, energy of self-heating processes of substances and materials (spontaneous combustion), etc. Special attention should be paid to the identification of ignition sources available in production. Finding out the conditions in which the gorenje process took place during the fire, especially before it was detected, is directly related to determining the period of the fire's onset, and therefore to the study of certain versions about the cause of its occurrence
