Рortable means of smoke and heat dissipation to increase the efficiency of fire extinguishing by civil protection operative-rescue service units of the state service of SSES of Ukraine ; Переносні засоби димо- та тепловидалення для підвищення ефективності гасіння пожеж підрозділами ОРС ЦЗ ДСНС України

One of the priority tactical methods for reducing the effect of high temperatures and smoke on the personnel of the fire and rescue units is to control the heat drift flux of fire with the help of fire smoke exhausters, which are functionally designed for local increase of air pressure by injecting clean air into the work area of the staff or removing combustion products from premises in the conditions of fire for the normalization of temperature and air environment in order to ensure safe conditions during rescue operations. The analysis of the rescue operation of the rescue services of the world leading countries indicates the considerable tactical significance of the use of portable fire extinguishers. Modern fire extinguishers, which are used by the rescue services of the leading countries of the world nowadays, are more maneuverable due to their installation on wheels, the dimensions are more compact and there is the possibility of their assembly, the capacity for fresh air is up to 60000–70000m3 / h.In the fire and rescue subdivisions of the SSU of Ukraine, fire extinguishers are practically not used. In order to assist in solving this problem, Ukrainian Civil Protection Research Institute began the implementation of research work, the purpose of which is to substantiate the technical requirements for modern portable fire extinguishers and to develop proposals for improving the efficiency of fire extinguishing with their use. To achieve the goal in the framework of this study, the authors plan to solve the following tasks: to conduct an analysis of information on the availability and use of portable fire extinguishers by the fire and rescue units of the leading countries of the world; to carry out the analysis of the normative and technical documentation, in particular to study the technical requirements for portable fire extinguishers from the leading countries of the world; to conduct a patent search on the given issue; to conduct mathematical calculation of technical parameters for the creation of a ...
