The purpose of the work is to analyze fire prevention measures in structures of external walls with facade thermal insulation and plastering, as well as to analyze the features of their arrangement, taking into account the experience of neighboring countries. The application of exterior wall designs with facade thermal insulation with plaster finish, as well as problems related to their fire hazard, are substantiated. The works are analyzed to investigate the problems of fire safety of exterior wall structures with facade thermal insulation and plastering, as well as hinged facade systems. The types, design features, purpose and functions of fire belts and framing of window (door) openings made of non-combustible materials, which are arranged in exterior wall designs with facade thermal insulation and plaster finish, are considered and analyzed. The role of floor fire belts and the framing of window (door) openings made of non-combustible mineral wool boards have been established. It is concluded that the use of structures of the exterior walls of residential buildings with facade thermal insulation with a combustible insulation and plastering significantly increases their level of fire danger. This danger will depend both on the properties of the individual materials (in particular the insulation), and on the design features of the entire thermal insulation system and the building as a whole. For plaster systems of thermal insulation of facades, the rapid spread of fire on the higher and lower floors of the building is a big threat. Frequent causes of fire of thermal insulation systems of external walls is the tipping of fire from a window opening of a building as a result of intense fire indoors. Materials of decorative and protective finishing of walls should meet requirements of normative documents on designs of external walls with facade thermal insulation and plaster finish, and their constructive execution will depend on the height of the building and functional purpose of the object. Fire-fighting measures, foreseeing in the construction of exterior walls with facade thermal insulation and plastering, intended to ensure their fire safety during the time necessary for the safe evacuation of people from the building, the arrival of units of fire and rescue units and extending the fire throughout its distribution.

The article is dedicated to the fire resistance limit of building structures of the objects for the storage of flammable and combustible liquids. Today, oil stores are very important elements of the oil supply system in Ukraine. The analysis of literary sources has shown that fires in oil stores cause extra fire hazard of surrounding objects. Increasing of their scales requires further improvement of fire safety measures during planning and using of oil stores. Fires in such buildings are tricky and large; they cause great harm and often lead to the death of people; their liquidation is very difficult. Theoretical calculations shown that the collapse of structures of the packaged oil stores and, as a result, significant material losses and the threat to people's life and health, were resulted from the incorrect selection of building structures and the discrepancy between the fire resistance of these structures and the applicable norms and requirements for such buildings. Fire Safety, №34, 2019 9 Fire resistance limit of the metal double-T pillar made of steel ВСт3пс4 (profile size number 30) was calculated in the article. Such constructions are used in oil stores. The obtained fire resistance limit of a metal double-T pillar is about 16 minutes (R 16). According to the normative documents for buildings of this type (the degree of fire resistance of the building – III), it should be 120 minutes (R 120). Even if the calculation method has an error due to the choice of another steel grade, objectively none of the double-T profiles from the assortment list would provide proper fire resistance limit.

The article deals with the problems of fire hazard of electricity-generating equipment during their exploitation. Intensive electrification of industrial and residual objects leads to the saturation of these objects with different electricity-generating equipment. Functioning of such equipment is accompanied with high heat emission and contains significant fire hazard. The electric current in an electrical conductor produces heat, when electric energy turns into thermal. All electrical equipment must be produced in strict adherence to fire safety rules and requirements. Ignoring these requirements causes heating of conductors through all the length, spunking of isolation, sparkling and, as a result, breaking-out of fire. Therefore, reducing the probability of fire even in the cases of abnormal work, wrong exploitation and foreseen refuses is the main task during planning and exploitation of electrical equipment and also during selection of structural materials. The primary purpose of fire prevention measures in the electrical equipment is avoiding of its self-ignition, and localization of fire after the self-ignition of electricity-generating equipment. Fire safety during exploitation of electricity-generating equipment depends on its technical state. Correct choice of conductor cross section is very important. Protection stage of electrical equipment, type of wiring, and cable laying method must comply with environmental conditions and have the proper climatic implementation and placement category. Proper protective devices from a short circuit and overloads must be used. Their operating values must be also foreseen. All above-mentioned measures prevent fires and explosions during exploitation of electrical equipment. Key

Hydrogen Energetics

Introduction. Now many countries produce measures for a transfer of their economics to an application of a hydrogen energetics. Because of a high fire hazard of hydrogen a fire safety provision of infrastructural objects of the hydrogen energetics is a very important task. The infrastructural objects of the hydrogen energetics are the facilities aimed on a production and storage of hydrogen, transportation of gaseous (GH2) and liquid (LH2) hydrogen, an application of hydrogen for an energy generation, car refueling stations etc. Scientific basis for a creation of the fire safety normative documents was laid in studies of Russian and foreign investigators.Russian normative documents. Russian normative documents in the area considered are analyzed in this work. A draft of the Technical Regulation on a safety of the facilities aimed on production, storage, transportation and application of hydrogen is the most important among them. This document contains a lot of specific requirements which should be used independently of a type of the hydrogen facility. Therefore this document can be considered as extremely “rigid” for a practical applications. A set of rules SP 162.1330610.2014 is aimed on the regulation of the safety requirements for the facilities using liquid hydrogen. The document PB 03-598-03 considers the safety requirements for a production of hydrogen by an electrolysis of water. A conclusion was made that Russian normative basis is not sufficient for a development of the hydrogen energetics.Standard NFPA 2. The standard NFPA 2 can be considered as a most important normative document containing the safety requirements for the facilities for production, storage, transportation and application of hydrogen in a gaseous and a liquid phase. This standard contains both general and specific requirements for the infrastructural objects such as car refueling stations, storages of hydrogen in the gaseous and the liquid phase and also using metal hydrides, hydrogen production facilities, energy generation objects using hydrogen, technological equipment containing hydrogen, laboratory facilities, car parks for the cars using hydrogen as a fuel etc.Conclusions. It was found that there is no comprehensive set of the normative documents regulating fire safety of infrastructural objects of hydrogen energetics. The series of the Russian normative documents in this area which should be created was proposed. A conclusion was made that the requirements of NFPA 2 can be used at a creation of the Russian normative basis of the hydrogen energetics.

Materials Used

The most basic way to keep comfortable indoor environments for a building’s occupants and save energy for space heating and cooling in residential buildings is to insulate the building envelope. Among the building materials to be used, thermal insulation materials primarily influence thermal performance. In particular, the type, thermal conductivity, density, and thickness of heat insulator, are important factors influencing thermal insulation performance. We investigate the design status of residential buildings which were designed in accordance with the building code of Korea and selected the type of thermal insulation materials applied to the walls of buildings. The present study aims at measuring the thermal conductivity of thermal insulation materials used for building walls of residential buildings. In this study, after collecting the design documents of 129 residential buildings, we investigated the type and thickness of insulation materials on the exterior wall specified in the design documents. As the thermal insulation materials, extruded polystyrene (XPS) board and expanded polystyrene(EPS) board are used the most widely in Korea when designing residential buildings. The thickness of thermal insulation materials applied to the exterior wall was 70mm, most frequently applied to the design. We measured the thermal conductivity and the density of XPS board and EPS board. When the density of XPS and EPS was 30~35 kg/㎥, the thermal conductivity of XPS was 0.0292 W/mK and it of EPS was 0.0316 W/mK.

The article is dedicated to the use of structures of external walls with facade insulation with plaster, which is widespread and popular in our country and abroad, as well as the problems associated with their fire hazard. The work of domestic and foreign researchers dealing with fire safety issues of facade systems has been analyzed. Classification of prefabricated systems of facade insulation is performed depending on the design decision, as well as on the main features in accordance with: the type of applied insulation material; a method of fastening a heat-insulating layer; composition of the base plaster layer; kind of decorative protective layer. The structure of prefabricated systems with complete sets of insulation with prefabrication of light, thick-layer plaster or fine-wares products is represented. The peculiarities of the processes that occur during combustion of the thermal insulation and finishing system of the outer walls of residential buildings are analyzed and revealed. Typical scenarios of fire spreading are presented with a surface of the design of external walls with a facade heat insulation with a fuel heater and a stucco coating. The mechanism of propagation of fire through a window opening by a surface of a facade heat insulation on the basis of foam polystyrene is described. The conclusion is made that the use of structures of exterior walls of residential buildings with facade insulation with combustible insulant and stucco coating significantly increases their level of fire hazard. This danger will depend on both the properties of individual materials (including insulant), as well as on the design features of the entire thermal insulation system and the building as a whole. For plaster systems, the thermal insulation of facades is a major threat to the rapid spread of fires on the floors above and below the building. The most common causes of thermal insulation fires is the transfer of fire from the windows during intense fire inside the rooms.

Introduction. In order to protect objects from dangerous manifestations of fire of cable products, electrical lines are designed and projected in accordance with the fire-protection requirements and the normative documents. Purpose. The purpose of this article is to analyze this problem in several areas concerning the situation with a systematic approach to the technical regulation in Ukraine of such a sector of fire safety as the requirements for cable-wiring lines. Methods. Methods of research: calculations using a mathematical model; comparison of the results of the calculation, forecasting of the boundary parameters of the technical condition and monitoring of the cable material properties; examination, qualification, definition of indicators of fire safety of cables and wires in the composition of the electrical grids of buildings, structures, foundations and metal structures, taking into account laying conditions. Different methods for volume and mass calculating, fire tests of electrical and fiber optic cables were applicated. Tests of vertically arranged wires or cables laid in beams on the vertical propagation of the flame (Category A F / R, Category A, Category B) were conducted. Results. The experimental study of the installation parameters test and indicators of fire safety for cable-wiring products in their vertical laying that reduce the overall fire safety level of facility electric power operation were conducted. Critical analysis of the current state of development was done. The basis of the fire safety requirements for standardization of cable lines were formulated. The measures for testing methods implementation with description of these methods were proposed. Conclusion. Determination of the combustible material quantity by volume and by mass is not regulated in the current normative documents on fire safety, although this criterion is often used precisely when establishing requirements for fire safety: to buildings, cable installations, to the installation of fire automatics systems and to others. A method for calculating the volume of combustible material for determining the fire risk of cable-conductive products is proposed. The method can be used during designing of wiring lines and during their exploitation. Experimental researches of fire hazard indicators of cable-wiring products were conducted; their group of flame distribution was installed. The method of determining the quantity of combustible material by volume, by mass and with testing of mass loss of combustible material was applied.

Рассмотрены российские и международные нормативные документы, отражающие специфические требования к объектам инфраструктуры водородной энергетики, к числу которых следует отнести объекты получения газообразного (GH) и сжиженного (LH) водорода, хранилища водорода (газообразного, сжиженного и в виде гидридов металлов), автозаправочные станции с использованием GH и LH в качестве моторного топлива, энергетические установки с применением водорода, предприятия по обслуживанию автомобилей на водородном моторном топливе. Выявлено, что в настоящее время в Российской Федерации отсутствуют нормативные правовые документы, определяющие специфические требования к перечисленным выше объектам водородной энергетики, а нормативные документы в указанной области весьма немногочисленны. Среди международных нормативных документов в первую очередь следует отметить стандарт NFPA 2, детально регламентирующий требования пожарной безопасности для объектов инфраструктуры водородной энергетики. Представляется целесообразной разработка российских нормативных правовых и нормативных документов в рассматриваемой области, учитывающих передовой международный опыт.

Неточное определение термина порождает неоднозначное толкование и, как следствие, искажение (неправильный выбор) противопожарных мероприятий. Авторы данной статьи проанализировали несколько наиболее часто употребляемых терминов, используемых в нормативных правовых актах и нормативных документах, и пришли к выводу, что определения многих терминов нуждаются в корректировке, а также сформулировали предложения по изменению определений некоторых терминов и отдельных пунктов Технического регламента о требованиях пожарной безопасности и сводов правил. An inaccurate definition of the term generates the polysemantic interpretation and, as a result, falsification (incorrect choice) of fire prevention measures. The authors of the article analyzed several of the most frequently used terms applied in regulatory legal acts and normative documents. The authors concluded that the definitions of many terms need to be adjusted. The authors also formulated proposals for changing the definitions of certain terms and particular paragraphs of the Technical Regulations on fire safety requirements as well as Codes of Rules.

In this study, subjective questionnaires and a building energy simulation were utilized to investigate the impact of air conditioner operation on the energy consumption/savings of a model building with different types of exterior wall thermal insulation. The results indicate that an intermittent energy usage mode is generally used in residential buildings in hot summer and cold winter areas. Air conditioner operation behavior is affected by the human thermal experience. The greater the indoor temperature deviates from the human comfort range, the higher the air conditioner operation frequency. Under continuous energy usage mode, the annual heating and cooling effect of the exterior thermal insulation was found to be better than that of interior thermal insulation. Under the intermittent energy usage mode without considering residents’ temperature tolerance, the annual heating and cooling effect of the interior thermal insulation was better than that of the exterior insulation. Under the intermittent energy usage mode considering tolerance levels, the energy-saving effect of the interior and exterior thermal insulation of the exterior wall was different. In the case of low and medium temperature tolerance, the annual heating and cooling energy-saving effect of the interior thermal insulation was better than the exterior thermal insulation; in the case of high tolerance, the heating and cooling energy saving effect of the exterior thermal insulation was better.
