ASSESSMENT OF FIRE-EXPLOSIVE HAZARD OF DISINFECTANT CREATED ON THE BASIS OF HYDROGEN PEROXIDE AND ETHYL ALCOHOL WHEN USED ON RAILWAY TRANSPORT

Представлены результаты лабораторных и крупномасштабных экспериментальных исследований пожаровзрывоопасности дезинфицирующего средства, включающего в себя перекись водорода и этиловый спирт, при применении его в виде аэрозоля холодного тумана. Исследования проводились в условиях, приближенных к реальным условиям дезинфекции вагонов железнодорожного транспорта. На основе проведенных исследований и экспериментов определены пожаробезопасные режимы обеззараживания вагонов железнодорожного транспорта с помощью данного дезинфицирующего средства. This paper is devoted to the study of the fire-explosion hazard of a disinfectant when applied as a cold fog aerosol. Currently, Rospotrebnadzor, public health authorities and institutions are concerned about the current sanitary and epidemiological situation on the territory of the Russian Federation, which is directly related to intensive transport communication. Railway transport occupies a leading position in the transport system of the Russian Federation in terms of transportation and the number of passenger flows. Therefore, there are set high tasks to ensure sanitary and epidemiological well-being of passenger transportation services. The overwhelming majority of disinfectants used for disinfection of railroad cars contain ethyl alcohol and they are flammable liquids, which makes it necessary to conduct studies to assess their fire-explosive hazard. The article deals with a disinfectant used for disinfection of air, surfaces in rooms and railroad cars. The disinfectant is sprayed using a cold fog generator capable of spraying 90-95% of the disinfectant in the form of an aerosol. Disinfection is carried out in a closed room with no people present. On the basis of the conducted research the fire-safe modes of disinfection of railroad cars with disinfectant are determined. Fire safety requirements are developed for the technology of disinfection of railroad cars with disinfectant when applied in the form of cold fog aerosol. The relevance of this article is that only disinfectants that have undergone experimental studies and meet all fire safety requirements can be used for disinfection of railroad cars in order to improve the sanitary and hygienic condition of passenger facilities and reduce the risk of emergence and spread of infections.
