The paper considers modern spectral analysis methods as tools for performing fire-technical expertise. The subject of analysis, as a rule, are commercial petroleum products. At the same time, the capabilities of the methods allow not only the traditional identification of individual substances, but also the qualitative and quantitative analysis of multicomponent mixtures. The analysis of the main characteristics of the equipment available in the FSBI SEU IPL, used in the study of commercial petroleum products for the purpose of fire technical expertise, is carried out
methods of fire-technical expertise, causes of fires, arson, infrared spectroscopy, identification of substances
