Introduction. The use of fireproof tent fabric at children’s tent camps remains a relevant problem. It may be resolved by developing a special flammability assessment methodology and criteria applicable to materials, used as the structural framework of tents. This solution will determine the choice of fabric.Aims and purposes. Materials, currently used to make tents, include natural or synthetic fabric and various polymers, that may be a fire hazard. In case of fire, safe evacuation of people may be unfeasible, although it is particularly important for children’s seasonal tent camps designated for sports and leisure.Domestic regulatory documents, that are currently in force, contain solely general technical requirements applicable to travel tents or ensuring fire safety in the territory of children’s tent camps, but there are neither fire safety requirements applicable to tent materials, nor any methods of their assessment. Meanwhile, there were cases of fire at children’s tent camps.The purpose of this work is to establish fire safety requirements applicable to tent materials used at children’s tent camps, to develop their testing criteria and methodology.The main objectives to be accomplished in order to achieve the pre-set purpose include the analysis of effective regulatory requirements and methods used to determine the flammability of tent materials, the establishment of parameters and criteria designated for their assessment and the development of a standard testing methodology.Results and discussion. Experimental studies were carried out to assess a set of flammability-related parameters of several types of fabric and polymers used to make outer/inner tents and ground sheets. It has been determined that currently used materials are fire-hazardous; therefore, it is advisable to limit the production of tents from combustible and flammable materials whose combustion may be triggered by low-calorie ignition sources, including those that can melt or release toxic combustion products.Currently used standard methods were applied to develop modified methodologies and classification criteria needed to assess the flammability of tent materials for children’s summer camps; experimental studies were also carried out.Conclusions. A draft national standard has been developed; it implies the establishment of the flammability assessment methodology and criteria and restricts the use of tent materials, that are extremely hazardous in terms of the toxicity of their combustion products.

This article presents the results of the assessment of compliance with fire safety requirements of the building of the poultry house for 200,000 heads of Avangard LLC of the Republic of Mordovia, made on the basis of fire risk calculations. The analysis of factors affecting the quality and reliability of the results of calculations is carried out. During the research and evaluation of the objects compliance with fire safety requirements were guided by the provisions of the Technical regulations on fire safety requirements. A list of technical regulations applicable to the object under study was defined. The article gives the fire-technical characteristics of the object under study, the class of functional fire hazard (agricultural buildings). The conducted research has established that the object of research meets the requirements of fire safety. Calculations on fire risk assessment were fulfilled by comparing the calculated values of fire risk with the normative value. For the considered object of protection the fire hazard analysis including the analysis of building characteristics (space-planning, design and technical solutions), fire protection systems, and features of functioning taking into account contingent and distribution of fire load in rooms was completed. The calculation of the risk of the gas supply system was considered the impact of the flame during the combustion of gas released in case of emergency depressurization of the pipeline. The potential risk in a poultry house near a gas pipeline with a diameter of 50 mm will be 1.7810-5, near a gas pipeline with a diameter of 70 mm - 4.410-7, and in total - 1.82410-5. The individual fire risk for employees of the poultry house building is 8.3110-7 year-1. Calculations of the spread of fire hazards and the time of evacuation of people are made using software that allows to create graphical models of space-planning solutions of buildings. With the introduction of the fire risk assessment system at the legislative level, the owners of objects have the opportunity to optimize the cost of fire safety with the required level of safety of people.

Introduction. Fire risk can be assessed qualitatively and quantitatively. A qualitative method for assessing fire hazard of the technological process (risk analysis) involves a detailed consideration of possible deviations from the technological regulations and failures in the production technology. Therefore, it can significantly increase the reliability of the hazard analysis to justify the technical decisions made to improve fire safety of production. Goals and objectives. Quantitative methods for analyzing fire hazard of technological processes and assessing fire risk have a number of significant drawbacks, they use various models, in which not always reasonable assumptions are often made. The use of such methods sometimes casts doubt on the results obtained. Hazard analysis using a qualitative analysis method is a sequential process of identifying violations not only of technological regulations, but also of fire safety requirements, and, consequently, the causes of accidents. Therefore, one of the most important purposes of this process is to check that all fire safety requirements are met. Methods. Method for assessing fire hazard of production technology by analyzing the consequences of "What happens if...?" (qualitative method of fire hazard assessment) allows us to consider problems related to possible causes of damage to technological equipment, the consequences of these causes, and the options adopted in the considered production for their prevention. The method is based on the development of a list of hazards, their division by hazard level and determining the most dangerous situations on this basis. Such a division makes it possible to increase the efficiency of the developed technical solutions that increase the level of fire safety of the production technology. Results and discussion thereof. The article reveals the essence of the method for assessing the fire hazard of production technology by analyzing the possible consequences of violations of technological regulations. The place of this method in the expert assessment of the fire hazard of production is shown and an example of the practical use of the method is given. Conclusion. Qualitative method of assessing fire danger of the technological process can complement quantitative methods, it can be their integral part, for example, when calculating the fire risk of production facilities, and it can act as an independent method for small enterprises in which it is not required to conduct a state expertise of projects, as well as when there is a need to assess compliance with fire safety requirements of the technical solutions adopted at the stages of design and operation of production.

Risk Categories

Introduction. A mathematical model is presented for assigning protection objects to certain risk categories in the field of fire safety. The model is based on the concepts of the probability of adverse effects of fires causing harm (damage) of various extent and severity to the life or health of citizens, and the acceptable risk of harm (damage) from fires. Goals and objectives. The purpose of the study is to develop the procedure for assigning protection objects to a certain category of risk of harm (damage) based on estimates of the probability of fires with the corresponding severity consequences, to determine the acceptable level of risk of harm (damage) due to the fires, to calculate and develop numerical values of criteria for assigning objects of protection to the appropriate risk categories. Methods. The boundaries of the intervals corresponding to certain risk categories are determined by dividing the logarithmic scale of severity of adverse effects of fires into equal segments. Classification methods are used to assign objects of protection to a specific risk category. Results and discussion. Based on the level of severity of potential negative consequences of a fire, risk categories were determined for groups of protection objects that are homogeneous by type of economic activity and by functional fire hazard classes. The risk category for each individual object of protection is proposed to be determined using the so-called index of "identification of a controlled person" within a group of objects that are homogeneous by type of economic activity and class of functional fire hazard. Depending on the risk category, the periodicity of planned control and supervision measures in relation to the specific object of protection under consideration is determined, taking into account its socio-economic characteristics and the state of compliance with fire safety requirements by the controlled person. Conclusions. To develop criteria for classifying protection objects that are homogeneous in terms of economic activity and functional fire hazard classes, the probability of negative consequences of fires, that are causing harm (damage) of various extent and severity to the life or health of citizens, and the acceptable risk of causing harm (damage) as a result of fires, is used. The risk category for each individual object of protection is determined taking into account socio-economic characteristics of the object that affect the level of ensuring its fire safety, as well as the criteriaof integrity of the subordinate person that characterize the probability of non-compliance with mandatory fire safety requirements at the object of protection. Calculations are made and numerical values of criteria for assigning protection objects that are homogeneous in terms of economic activity and functional fire hazard classes to a certain category of risk are proposed. Key words: object of protection, probability of fire, acceptable level of risk, risk category, dangerous factor of fire, death and injury of people.

The Impact

This chapter deals with materials used in safety and security engineering. The most commonly used materials in this field include shielding materials, materials for protective suits, electrically insulating materials and materials for fire protection. The first part of the chapter describes the properties of materials used in the above applications. The second part of the chapter focuses on characteristics of materials that accurately describe their fire risk. The fire risk of a material is quantified by its resistance to ignition (determined generally by critical heat flux and ignition temperature) and by the impact of the fire on the environment. The impact of fire is usually determined by the heat release rate, toxicity of combustion products (primarily determined by carbon monoxide yield and for materials that contain nitrogen, also through the hydrogen cyanide yield) and the decrease of visibility in the area (depending on the geometry of the area and the smoke production rate).

Проанализирован международный опыт реформирования проверок соблюдения требований пожарной безопасности и внедрения риск-ориентированного подхода. Разработана модель отнесения объектов защиты к категориям риска в зависимости от вероятного причинения вреда, который рассчитывается исходя из количества погибших и травмированных при пожарах людей. Сформулированы критерии отнесения объектов защиты к категориям риска. Выполнен расчет категорий риска для групп объектов, однородных по группам экономической деятельности и классам функциональной пожарной опасности. Проведено сравнение с существующей классификацией объектов защиты по категориям риска. The international experience of reforming of fire safety compliance checks and implementing a risk-based approach is considered. There are presented methodological approaches to calculating the risk of causing harm (damage) in buildings (structures) as a result of fire for the purpose of assignment of buildings and structures according to risk categories as well as justification of the frequency of scheduled inspections at these facilities. There is calculated the probability of fire occurrence for a group of objects of protection that are homogeneous by type of economic activity and functional fire hazard classes in order to assign objects of protection to certain risk categories. The social damage expressed in the death and injury of people as a result of fire is also calculated in order to assign objects of protection to certain risk categories. Classification of objects of protection according to the risk categories is performed using the indicator of the severity of potential negative consequences of fires. This indicator characterizes the degree of excess of the expected risk of negative consequences of fires for the corresponding group of objects of protection in relation to the value of the permissible risk of negative consequences of fire. The permissible risk of negative consequences of fires is calculated on the basis of statistical data, taking into account the value of the individual fire risk of exposure of critical values of fire hazards on person in buildings and structures. The criteria for assigning groups of objects of protection to the appropriate risk categories are formulated on the basis of formation of distribution of numerical values of the severity of potential negative consequences of fires. There are carried out the assessment of the severity of potential negative consequences of fires for objects of protection that are homogeneous by type of economic activity and functional fire hazard classes, and also the risk categories of the corresponding groups of objects are determined. The proposed classification of objects of protection according to risk categories is compared with the existing classification. The obtained results of calculations showed that scheduled inspections of objects of protection by the Federal state supervision bodies, depending on the assigned risk category and with corresponding frequency, have significant role in improving the level of fire safety of objects. The decrease in the intensity of scheduled inspections, at the same time, may lead to a corresponding decrease in the level of fire protection of objects.

The requirements for exterior finishing materials have been substantially established recently. After a fire at an apartment building in Uijeongbu City, fire safety requirements for exterior finishing materials used in the buildings that have six and more stories or are taller than 22 meters were specified in 2015, and three and more stories or are taller than 9 meters were specified in 2019. However, the buildings built before that may not accomplish the safety requirements and thus have fire safety problem. This study suggests a method for partially reinforcing the Exterior Insulation Finishing System (EIFS) of buildings to enhance the fire safety. EIFS specimens whose walls on the pilotis were reinforced with a mineral insulation material, were tested in accordance with BS 8414-1. The result showed that fire spread was delayed more than 9 min when compared with an EIFS specimen without reinforcement.

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.
