According to Article 117 of Russian Federal Law 123 of 2008, there is a class of objects historical buildings, exhibition complexes, energy facilities, etc. For these objects, it is not so necessary to eliminate the fire with automatic fire extinguishing systems, as to contain it until the arrival of fire departments. However, this law does not specify certain requirements for automatic installations, the main working substance of which is water and the solutions. The current situation makes it difficult to design, install and test automatic fire control systems. Given this, as well as the foreign experience and domestic developments in the field of automatic fire extinguishing systems, it is important to conduct a special research work. In this work, it is necessary both to conduct several fire tests in terms of the development of a fire with a limited water supply intensity, and to develop a draft of standard “Water automatic fire containment installations. General technical requirements. Test methods”.

Fire Hose

The urgency of the issue of substantiation of technical requirements to fire-fighting layflat delivery hoses for fire-rescue equipment is given. Fire hoses are a significant component of fire fighting equipment. According to DSTU 2273, a fire hose is a flexible conduit fitted at the ends with connecting heads intended for the transport of extinguishing agents. Among the technical means intended for the transportation of extinguishing agents to the fire cell, the main role is certainly played by delivery fire hoses. According to DSTU 2273 delivery fire hoses (in EU countries they are classified as "layflat") are intended for transportation of extinguishing agents under excess pressure. At present, there are a number of standards in Ukraine and in the leading countries of the world that set the technical requirements for delivery fire hoses, in particular those used in conjunction with fire rescue equipment, namely DSTU 3810-98, DIN 14811, EN 14540: 2004 + A1: 2007, etc. In addition, a draft state standard is being developed in the Republic of Belarus. Considering the process of gradual integration of Ukraine into the European Union and the fact that the requirements of the current national standard DSTU 3810-98 do not meet the modern European requirements for layflat delivery hoses for fire-fighting equipment, a pressing issue is the justification such types of hoses. In order to assist in solving this problem, the Ukrainian Research Institute of Civil Protection is currently conducting a research work "Justification of fire hose test methods", within which a national standard will be developed, which regulates general technical requirements and test methods for the fire-fighting layflat hoses for fire – rescue vehicles. The basic technical requirements for the specified hoses, which meet the modern requirements of the EU and which, after appropriate experimental justification, can be considered in the draft national standard, which regulates the general technical requirements and test methods for the fire-fighting layflat hoses for fire – rescue vehicles to be developed. This publication lists six tables that provide basic specifications for delivery fire hoses. Keywords: abrasion, burst pressure, layflat delivery fire hoses, fire – rescue vehicles, proof pressure, technical requirements, specifications, working pressure.

Рассмотрены этапы и направления создания и производства пожарных автомобилей (ПА) в современной России. Этот период отражен в виде четырех этапов. Значение 1-го 5-летнего этапа воспроизводства ПА после распада СССР (до 1997 г.) состоит в присоединении к двум старейшим предприятиям - изготовителям ограниченного ряда ПА еще шести предприятий с освоением новых типов и моделей основных и специальных ПА в количестве 55 ед. На 2-м этапе (до 2008 г.) создана нормативная база в виде норм пожарной безопасности (НПБ) по разработке, производству и испытанию различных классов ПА. Разработка Типажа ПА на 5-летний период стала базироваться на мониторинге потребности ПА территориальных управлений. В этот период сократились среднегодовые темпы роста освоения новых типов и моделей ПА, но улучшилось качество их изготовления, как с реализацией требований новой нормативной базы, так и за счет использования технологий и компонентов зарубежных производителей. С этого периода началось освоение производства ряда пожарных насосов и стволов нового поколения, которыми стали оснащать ПА. С введением в действие Федерального закона № 123-ФЗ начался 3-й этап создания и производства ПА. Разработана и внедрена нормативная база - национальные стандарты, определяющие классификацию, номенклатуру показателей и технические требования к ПА. Создан ряд типов и моделей ПА с инновационными составляющими. The article reflects the 4 time stages of creation and manufacture of fire vehicles (PA) in modern Russia after the collapse of the USSR. During the first stage until 1997 there were developed and mastered basic PA in the amount of 55 units meeting the needs of fire protection of the country at that time period. During the second stage until 2008 there was defined and created the regulatory framework in the form of fire safety standards (NPB) for the main range of fire vehicles for basic and special purposes. Data on the rate of manufacture of fire vehicles in comparison with the first period of manufacture are presented. There was mentioned the improvement of production quality with the use of new technologies and foreign experience in creating such models. When developing «PA Types» for a five-year period the monitoring of territorial departments of EMERCOM of Russia, which determines the need for a certain type and model of PA, has become important. The standard configuration of PA is defined by the order of EMERCOM of Russia. Since 2009 the third stage in PA creation has begun, taking into account the effect of Federal Law No. 123 dated June, 22 as well as the developed national standards for PA, which defined the classification, nomenclature and technical requirements for PA. The number of innovative models of these products were created during this period including: fire and rescue evacuation and tunnel vehicles, PA for operating conditions at temperatures up to below 60 °C, pump and hose systems, and others. The interstate standard GOST 34350-2017 (since 01.03.2019) is put in force during the fourth stage of the creation and production of PA in 2019.This standard defines the general requirements for basic PA and their test methods. The technical regulation TR EAEU 043/2017 (since 01.01.2020), reflecting the requirements for fire safety and fire extinguishing equipment, is put into effect at the same time. In 2019 with elaboration of draft of Concept for development of fire and rescue equipment until 2030 (2018), there is the beginning of new period that determined the most important directions for development of PA until 2030. The importance of cooperation between customers, manufacturers and scientific organizations in the field of creating effective fire equipment is noted.

The protection of polar flammable liquid storage tanks from fire is an important matter related to the safe production of enterprises and to the safety of people’s lives and property. Although the foam fire-extinguishing system has long been the main means for the fire protection of flammable liquid storage tanks, the influence of the physical properties of polar flammable liquids on the fire-extinguishing characteristics of alcohol-resistant foams has not been well studied, which causes many problems for engineering design. In the present work, 14 kinds of polar flammable liquids were used to carry out non-ignition tests and alcohol-resistant foam fire-extinguishing tests. The results show that water-miscible and water-immiscible polar flammable liquids exhibit significant differences in their interactions with the alcohol-resistant foams under non-ignition conditions. A lower specific gravity and a higher heat of combustion of polar flammable liquids will result in a longer time needed for fire control, and a higher saturated vapor pressure of polar flammable liquids will result in a longer time needed to extinguish the edge fire. In addition, the tests show that the forceful application of alcohol-resistant foams is not conducive to extinguishing fires involving polar flammable liquids and cannot even control the fires.

В статье отражены результаты обсуждения наиболее актуальных вопросов, возникших при формировании технических требований к фонарям пожарным при разработке межгосударственного стандарта «Техника пожарная. Фонари пожарные. Общие технические требования. Методы испытаний». Предложения, требующие подробных разъяснений, касаются количества циклов применения фонаря, обоснования принятого уровня освещенности и разработки требований к нормированию светового потока источника света фонаря. На основании качественных испытаний четырех наиболее распространенных моделей групповых фонарей в подразделениях противопожарной службы Российской Федерации, проведенных испытательной лабораторией института в период с 2010 по 2018 год, сформулированы основные их эксплуатационные показатели. This article contains some comments and suggestions that caused a discussion during the consideration of the draft of the interstate standard provisions “Fire fighting equipment. Fire lanterns. General technical requirements. Test methods”. The proposals that require detailed explanations include issues related to the cycle life of lamp, the justification of the accepted level of illumination and the development of requirements for the normalization of the luminous flux of the lamp light source. As a reference point for determining the cycle life of the flashlight there was selected the battery. Based on the standard indicators of the resource of different types batteries the value of cycle life of the flashlight is equal to 400. On the base of the qualitative tests on the four most common models of group lamps in the divisions of the fire service of the Russian Federation, conducted by the testing laboratory of the Institute for the period from 2010 to 2018, the main operational indicators are formulated as the following: “The time of continuous illumination of the lamp under normal conditions according to GOST 15150, excluding the time of triggering the warning alarm (FPG), should be at least 5 hours; the illumination of the working surface with the lamp must be at least 1500 lux during the entire glow time”. The introduction of requirements for the normalization of the luminous flux of the light source of the lamp is not provided.

It is established that the organization of fire extinguishing with the use of gel-forming compounds is a promising direction to increase the efficiency of extinguishing, especially in multi-storey buildings and structures of various functional purposes. Given the shortcomings of existing technical solutions for the use of gel-forming compounds for effective fire extinguishing, the need to develop new structures (spray barrels) is justified. The proposed solutions should ensure, above all, the safety of the fire rescuer. New designs of spray barrels must have a distance of supply of gelling compounds to make work of the operator safe, as well as meet the general technical requirements for fire extinguishers. An autonomous installation of extinguishing with gelling compounds for remote fire extinguishing by plane-radial jets of components of gelling compounds has been developed. It is proposed to fix the spray barrels with a special device to guide them to the object that has to be extinguished with verification of the angles to the horizon, angles of deviation relative to the plane of aiming, the height and width of the symmetrical placement. In this manner, it allows more efficient feeding at a distance of up to 10 meters of the two components of the gelling compounds and prevents premature or delayed mixing. Full-scale samples of RS-10 spray barrels were designed and manufactured to supply flat-radial jets of gel-forming compounds at a distance of up to 10 m. The method of optimal planning of experiments was used to calculate rational values of geometric parameters of the initial cross-section of the RS-10 spray barrel. The problem of 4-factor (second-order) optimal planning of the experiment of the process of plane-radial jet supply by means of RS-10 spray barrels is formulated and carried out. The main design parameters of the spray barrel (cutout of the rigid plate sector and its thickness) are determined, which correspond to the area of rational geometric parameters. The obtained results can be used in the design of extinguishing systems with gelling compounds
