ИССЛЕДОВАНИЕ ВОЗНИКНОВЕНИЯ ПОЖАРА ОТ ВОСПЛАМЕНЕНИЯ И ВЗРЫВА ПАРОВОЗДУШНОЙ СМЕСИ ПРИ ПРОВЕДЕНИИ ГАЗОСВАРОЧНЫХ РАБОТ

Using the example of a real fire that occurred as a result of violations of fire safety requirements during gas welding operations, it is demonstrated how the combined use of instrumental and computational methods makes it possible to determine the cause of the fire. The nature of combustible substances has been determined by fluorescence spectroscopy, gas-liquid chromatography and infrared spectroscopy. Using mathematical calculations, the amount of combustible substances necessary for the formation of an explosive mixture was determined. It is demonstrated how a combination of physical-chemical research methods and computational methods, allows for the determining the causal relationship between gas welding operations and the aforementioned explosion.

Methods for checking the quality of student learning are proposed.

Post-fire performance of hybrid GFRP-steel reinforced concrete columns

The fire safety requirements and knowledge on the use of Glass Fiber Reinforced Polymer (GFRP) bars as an alternative to conventional steel in reinforced concrete structures have been progressively evolving. This study investigates the post-fire axial performance of square GFRP reinforced concrete (RC) columns, addressing a significant gap in current knowledge. Five column specimens of the same cross-section and length were tested, where the main parameters considered are the clear cover depths (40, 50, and 65 mm) and the use of a 40-mm insulation on one column. The columns were subjected to a long 3-hour fire exposure per ASTM E119 standard without sustained loading. The columns were tested upon cooling under concentric axial loading. Despite the notable temperature differences between columns with 40 and 65 mm concrete cover (300 and 500 °C after 3 hours), the post-fire residual axial capacity appeared unaffected. This is primarily attributed to the minimal differences in the retained mechanical properties of GFRP bars at temperatures exceeding 200 °C. The study's findings indicate that GFRP longitudinal bars do not significantly influence the performance of columns in fires. Consequently, future research should focus on columns reinforced with GFRP ties as well. The predicted values of post-fire axial capacity closely match the experimental data for non-insulated columns, indicating a high degree of accuracy. The study provides design recommendations to enhance the fire performance of such elements. The use of insulation results in a substantial reduction of temperature at various depths of the column. Post-fire residual capacities for non-insulated columns were approximately 30 %, whereas insulated columns demonstrated a 60 % residual capacity.

Development of a framework to track life safety levels of occupants in the event of a fire in buildings

ABSTRACT In the operational phase of buildings, tracking what modifications can have an impact on the expected facility performances through manual checks can be impractical, albeit very important from a facility management perspective. The transition from the traditional prescriptive method towards the performance-based approach for building design and management may facilitate quantitative assessment of performances and may lead to conscious decisions which includes preparedness in the event of emergencies. The main goal of this paper is to develop a framework, compliant with a Building Information Modelling (BIM) environment, to track fire safety performance levels, in terms of life safety of occupants. As long as this is done through the definition of Key Performance Indicators (KPIs) that are being tracked continuously, facility managers can have a comprehensive and updated overview of current performances of a facility. More specifically, a single representative KPI was set and evaluated for several fire scenarios, using a set of simulation and data management tools. The results of the assessment were processed and transformed into a visual representation, referenced to a grid superimposed over the building layout to quantitatively represent the safety of occupants at every point of the building. The results were then sent back and displayed into the BIM model, for seamless accessibility by facility managers. The proposed methodology was tested on a pilot building, assuming two fire scenarios. This approach enabled supervision of a building’s compliance with fire safety requirements, in terms of occupants’ life safety, throughout the building lifecycle.

A comparative study between ultra-high-performance concrete structures and normal strength concrete structures exposed to fire

The use of ultra-high-performance concrete (UHPC) in civil infrastructure is increasing due to its numerous advantages compared to normal strength concrete (NSC). In this research, thermal analysis of NSC and UHPC beams and columns was developed to understand and compare the fire performance of these structures. A numerical analysis was performed using finite element (FE) modeling with ABAQUS software. Compared to NSC, UHPC structures in some cases have lower fire resistance due to their slender cross-sections and unfavorable thermal properties and mechanical capacity degradation due to temperature effect. The results show that UHPC structures experience significantly higher cross-sectional temperatures when exposed to fire compared to NSC. The results are particularly relevant for high-rise buildings, where fire safety requirements are more stringent and the use of UHPC is attractive, leading to an unprecedented contradiction. Alternative strategies for the application of UHPC, such as the contradictory increases in cross-section or the use of fire protection coatings, must be considered. In some cases, NSC may be more attractive as a structural material than UHPC if structural fire design requirements are taken into account.

Effect of diammonium hydrogen phosphate coated with silica on flame retardancy of epoxy resin.

Epoxy resin has become one of the most widely used polymers owing to their excellent comprehensive properties. However, the inherent inflammability of epoxy resin (EP) has seriously limited its application in a range of fields with high fire safety requirements. Herein, a novel shell-core hierarchy architecture (DAP@SiO2) was prepared, composed of diammonium hydrogen phosphate (DAP) and in situ grown silica, and its structure and morphology were characterized by electron microscopy and infrared spectroscopy. The results indicated that silica particles were uniformly coated onto the surface of DAP. The modified DAP was used to reinforce the epoxy resin. The thermal stability of the EP blends was studied with the use of thermogravimetric analysis. The diammonium phosphate in DAP@SiO2 flame retardant produces pyrolysis gases such as NH3 and N2 during decomposition, diluting the concentration of oxygen and flammable volatile products around the flame. Secondly, silica migrates to the surface of epoxy resin to form a shielding layer, forming compounds containing Si-O-Si and O-Si-C structures, which can be cross-linked with other condensed phase products, greatly improving the thermal stability of the carbon layer. Fire behavior was evaluated using the limiting oxygen index (LOI), vertical burning test, and the cone calorimetry, and the flame retardancy mode of action was explained. With 12% of DAP@SiO2 involved, the EP blend passes UL-94 V-0 level, and its limiting oxygen index (LOI) reaches 33.2%. The incorporation of DAP@SiO2 in an EP matrix showed a slight reduction in the heat release and smoke production. The flame retardant mode of the EP polymer shows that its flame retardant and smoke suppression characteristics are related to the interaction of flame retardants in the gas phase and condensed phase. The mechanical properties test results illustrated that the tensile strength, elastic modulus and impact strength of EP/3%DAP@SiO2 are improved compared with pure EP. This is due to the crosslinking reaction between a large number of amino groups on the surface of DAP@SiO2 and the epoxy group on the epoxy resin, which significantly enhances the interfacial compatibility between DAP@SiO2 and epoxy resin, making the combination of DAP@SiO2 and epoxy resin closer.

ОБЕСПЕЧЕНИЕ ПОЖАРНОЙ БЕЗОПАСНОСТИ МНОГОЭТАЖНЫХ ЗДАНИЙ ИЗ ДЕРЕВЯННЫХ КОНСТРУКЦИЙ

Проведен обзор современного деревянного домостроения в России и за рубежом. Проанализированы результаты испытаний строительных материалов из древесины на пожарную опасность, а также деревянных строительных конструкций различных типов на огнестойкость и пожарную опасность как без огнезащиты, так и с огнезащитой различных видов. Разработаны предложения в нормативные документы. Намечены направления дополнительных исследований пожарной опасности зданий из деревянных конструкций. The paper considers the issues of ensuring fire safety of multi-storey buildings made of timber frame construction. At present, wooden houses in Russia are built mainly in the individual housing sector and account for 22% of the total construction volume, while industrial wooden houses account for no more than 3% of the wooden houses built annually. Abroad, wood is also widely used in the construction of buildings of various functional purposes: hotels, sports facilities, public and administrative buildings, low-rise and multi-storey buildings. The achievements of science, technology and engineering in the field of timber construction make it possible to design and build buildings of any type and purpose. Modern technology makes it possible to build high-rise timber houses. For example, high-strength composite materials based on wood are used for the construction of multi-storey buildings, in particular LVL beams and CLT panels. Numerous tests carried out at VNIIPO on load-bearing elements made of solid wood (frames, beams) and load-bearing structures made of CLT panels (walls, ceilings) have shown that they provide a significant limit of fire resistance in terms of load-bearing capacity. It is well known that wood is a highly flammable material (G4). This circumstance significantly complicates the use of various building structures in construction from the point of view of ensuring fire safety requirements, including in multi-storey buildings. A set of necessary engineering, technical and organisational measures to ensure fire safety has been developed for buildings with wooden structures up to 4 storeys. Based on the results of these tests, there have been developed proposals to include fire technical parameters in the regulatory requirements for buildings of classes I–III of fire resistance and structural fire hazard class C3. Further research is necessary to develop proposals for inclusion in the regulatory documents for fire safety of multi-storey residential and public buildings made of timber structures up to 28 metres in height.

YOLOv8-EMSC: A lightweight fire recognition algorithm for large spaces

Stringent fire prevention requirements are imperative in expansive environments. Fire detection in diverse large-scale settings typically relies on sensor-based or AI-driven target detection methods. Traditional fire detectors often suffer from false alarms and missed detections, failing to meet the fire safety requirements of large-scale structures. Many existing target detection algorithms are characterized by substantial model sizes. Some detection terminals in large structures face challenges deploying these models due to constrained computational resources. To address this issue, we propose a lightweight model, YOLOv8-EMSC, derived from YOLOv8n. The incorporation of C2f_EMSC, replacing the C2f module, significantly reduces the model parameters in the enhanced YOLOv8-EMSC model compared to YOLOv8n, thereby enhancing model inference speed. Extensive testing and validation using a custom-built large-scale infrared fire dataset demonstrates a 9.6 % reduction in parameters compared to the baseline model for YOLOv8-EMSC, achieving an average precision of 95.6 %, surpassing both the baseline and mainstream models and significantly enhancing fire detection accuracy in expansive environments.

Features of fire danger in maternity hospitals

The article deals with the issue of fire safety in maternity hospitals, taking into account the specifics of patients (laboring women). The behaviour of pregnant and postpartum women and the fire safety requirements in terms of their vulnerability are considered. The article shows the dynamics of the number of fires and their causes in maternity hospitals in Russia for 2018-2022. It was found that when evacuating a building in the event of a fire, pregnant women experience difficulties due to stress and their psychological state. It is proposed to take additional measures to ensure the safety of pregnant or postpartum women and their newborn children in maternity hospitals in the emergency situation such as fires. The overall safety of patients in maternity hospitals should be a priority for any healthcare facility.

Ensuring fire safety: compliance tests for the use of polystyrene foam in facades systems

Ensuring fire safety is the most important thing in the construction industry, especially when it comes to facade materials. The inherent flammability of polystyrene foam poses significant safety concerns, especially when integrated into facade systems. Therefore, the main focus is on meeting the strict flammability requirements set for construction products, which are assessed by applying rigorous test procedures. This study focuses on the fire resistance testing of a facade system using EPS 70 with graphite additives. The system has been evaluated according to the strict DIN 4102-20 standards. Tests were conducted under real-world conditions to gain insight into the performance of the EPS 70 in real-world fire scenarios. Temperature measurements were taken at various points in the facade system, including at least 3.5 meters above the combustion chamber. The results showed that the temperature does not exceed 500 °C, so it is possible to quantify the thermal properties of the material and the ability to prevent the vertical spread of fire. After the tests, detailed post-test inspections were carried out to evaluate the internal flame propagation after removing the top layer of plaster. The study confirms that polystyrene foam EPS 70 with graphite additives meets the fire safety requirements of DIN 4102-20, which suggests that it can be used more widely in building facades to improve fire safety in residential and commercial buildings. The study highlights the importance of adhering to installation standards, emphasizing the need for accurate installation practices. It also encourages the development of new composite materials with similar or improved fire safety properties, laying the foundation for further innovations in fire-resistant materials

Урахування загальних засад призначення покарання у разі його призначення за вчинення кримінального право-порушення, передбаченого ст. 270 КК України

The article emphasizes the importance of strict adherence to the general sentencing principles for adequately implementing the principle of legality in criminal law. The author emphasizes that, unfortunately, the practice of sentencing for a criminal offense under Article 270, “Violation of fire or industrial safety requirements established by law” of the Criminal Code of Ukraine (hereinafter – the CC of Ukraine) is almost unexplored. The analysis of the practice of sentencing for committing an act under Art. 270 of the Criminal Code of Ukraine is based on the study of more than 50 verdicts publicly available in the Unified Register of Court Decisions. The author notes that there are no cases when a court exceeded the sanction when imposing a sentence for an act under Art. 270 of the Criminal Code of Ukraine indicates that the sanction for this offense formalized by the legislator is appropriate. The author notes the almost complete absence of cases of imposing punishment for an act under Part 1 of Article 270 of the Criminal Code of Ukraine, which indicates the absolute non-prevalence of this unlawful act in Ukraine. The author determines the list of provisions of the General Part of the Criminal Code of Ukraine which should be considered when sentencing. The author notes the problematic nature of direct consideration of the degree of gravity of the offense committed when imposing punishment, especially in the context of such consideration under Article 12 of the Criminal Code of Ukraine. The author determines that the analysis of the perpetrator’s personality as an element of the sentencing principle can form an idea of the portrait of a typical offender who commits a particular offense, which may further improve the activities aimed at its prevention. The article analyzes the main characteristics of persons brought to criminal liability for committing an act under Article 270 of the Criminal Code of Ukraine. The author determines that there is no significant diversity in the mitigating and aggravating circumstances that are considered by the court when imposing a sentence for an act under Article 270 of the Criminal Code of Ukraine. Keywords: criminal liability, sentencing, general principles, personality of the perpetrator, violation of fire or industrial safety requirements established by law, fire safety, industrial safety, differentiation of criminal liability, individualisation of punishment.

О некоторых вопросах состава нарушения требований пожарной безопасности

Taking into account the high-profile events in our country related to large fires in shopping and entertainment centers, as well as in connection with fires due to burning vegetation, the composition of Article 219 of the Criminal Code of the Russian Federation is of increased interest from the point of view of science and practice. Thus, it is proposed in the scientific community to expand its application, indicating in it as consequences the damage caused by fire to natural objects. After analyzing various points of view, the author came to the conclusion that such changes to the article under study cannot be made for a number of objective reasons (fire is not specified in Article 219 of the Criminal Code of the Russian Federation as a prerequisite; it is illogical to compare the damage caused to human life and health with damage caused to nature), here the question of introducing the corresponding article in the Criminal Code of the Russian Federation. Regarding the subjective side, the composition in question differs in the person’s delusion about his duties, taking them lightly, performing them in bad faith, believing that responsibility can be “shifted” to the head of the organization. At the same time, not any employee can be appointed authorized for compliance with fire safety requirements, but only one who is part of the management staff. In this regard, there is a proposal in scientific circles to expand the scope of Article 219 of the Criminal Code of the Russian Federation, removing the reference to a special subject in it.

Fire safety of building integrated photovoltaic systems—State of the art

The main long-term goal of international communities is to achieve sustainable development. This issue is currently highly topical in most European Union (EU) countries due to the ongoing energy crisis. Building Integrated Photovoltaics (BIPV), which can be integrated into the building surface (roof or facade), thereby replacing conventional building materials, contributes significantly to achieving zero net energy buildings. However, fire safety is important when using BIPV as a structural system in buildings, and it is essential that the application of BIPV as building facades and roofs does not adversely affect the safety of the buildings, their occupants, or the responding firefighters. As multifunctional products, BIPV modules must meet fire safety requirements in the field of electrical engineering as well as in the construction industry. In terms of building regulations, the fire safety requirements of the BIPV must comply with national building regulations. Within this article, aspects and fire hazards associated with BIPV system installations will be defined, including proposals for installation and material requirements that can help meet fire safety.

ЭКСПЛУАТАЦИЯ СТАЛЬНЫХ ПОКРЫТИЙ УНИКАЛЬНЫХ СООРУЖЕНИЙ.

Currently, employees of the Laboratory for Standardization, Reconstruction and Monitoring of Unique Buildings and Structures of the Department of Metal Structures of the V.A. Kucherenko Central Research Institute are preparing to print the standard of the organization STO 36554501-073-2023 “Technical operation of steel structures for coatings of unique buildings and Structures” in accordance with Federal Law No. 162-FZ dated June 29, 2015 “On Standardization in the Russian Federation Federation”. This SRT 36554501-073-2023 is compiled taking into account the requirements of Federal Laws: dated December 27, 2002 No. 184-FZ “On Technical Regulation”; No. 123-FZ dated June 22, 2008 “Technical Regulations on Fire Safety Requirements” and No. 384-FZ dated December 30, 2009 “Technical Regulations on the Safety of Buildings and Structures”. SRT 36554501-073-2023 applies to steel structures of unique coatings, including including large-span buildings and structures for maintenance, ensuring the safe functioning of buildings and structures. The standard provides an explanation of the concept of “unique buildings and structures”: these include buildings and structures with a height exceeding 100 m, or with a span of more than 100 m, or with a console departure of more than 20 m, or, if the depth of the underground part, relative to the planning mark of the ground, is more than 15 m, or structures where structures and structural schemes are used with the use of non-standard or specially developed calculation methods, or requiring verification on physical models, as well as sports and entertainment, religious buildings, exhibition pavilions, public buildings, shopping and entertainment complexes with an estimated stay of more than 1,000 people inside or more than 10,000 people near the facility. The article presents the materials that served as the basis for the creation of a service station for the operation of steel structures in the coatings of unique structures.

РЕЗУЛЬТАТЫ ИССЛЕДОВАНИЯ ПОДХОДОВ К ОБЕСПЕЧЕНИЮ ПОЖАРНОЙ БЕЗОПАСНОСТИ ПРОИЗВОДСТВЕННЫХ ОБЪЕКТОВ ГАЗОВОЙ ПРОМЫШЛЕННОСТИ В ЧАСТИ ПРОТИВОПОЖАРНЫХ РАССТОЯНИЙ

The article presents the results of a study of two approaches to ensuring fire safety of production facilities of the gas industry. As a result of the use of PromRisk software version 2.30.1, it is proved by a particular example that not always the fulfillment of all fire safety requirements established by regulatory documents on fire safety is due to ensuring the required amount of fire risk. An algorithm has been developed for determining the fire-fighting distance from a gas industry production facility to residential facilities based on the calculation of fire risk.

К ВОПРОСУ ОБ УГОЛОВНОЙ ОТВЕТСТВЕННОСТИ ЗА НАРУШЕНИЕ ТРЕБОВАНИЙ ПОЖАРНОЙ БЕЗОПАСНОСТИ

The article attempts to consider the theoretical, legal and practical aspects of the violation of fire safety requirements provided for in Art. 219 of the Criminal Code of the Russian Federation. The authors analyzed the most complex and practical issues related to the application of this rule of law from the standpoint of modern standards. The conclusions are substantiated that in judicial and investigative practice difficulties arise in the application of Art. 219 of the Criminal Code of the Russian Federation and these difficulties are associated, in particular, with the fact that this norm does not provide for criminal liability of individuals, regardless of their position, as well as the «amount of direct damage» caused by fires. In order to improve prevention and response measures to problems of fire safety violations, it is proposed to reconstruct the legal norms under consideration.

Assessment of recent UK fire safety guidance for covered car parks and electric vehicles

Guidance issued by organisations such as fire and rescue services, insurers and governmental bodies across the UK for the fire safety design of covered car parks is changing in response to the projected rapid growth in electric vehicle (EV) use. This new guidance is impacting the provision of parking bays, particularly in residential and mixed-use buildings. This paper considers whether EVs in covered car parks pose a greater fire risk than internal combustion engine vehicles (ICEVs) using recent data on the ignition frequency and the burning characteristics of EVs. The recommended mitigating fire safety measures within the new guidance are assessed with a focus on detection, smoke ventilation, sprinkler systems and structural performance as these have the potential to have the greatest impact on a building fire safety design. The paper indicates that the recommendations may not align with available evidence which challenges a balanced approach to fire safety requirements to prevent over-specification that could affect the feasibility of building designs. This paper summarises recent fire safety guidance in the UK on the use of electric vehicles (EVs) in covered car parks. Factors that contribute to the risk posed by EVs are investigated and practical design values for heat release and fire growth are suggested. Key recommended fire safety measures proposed in the guidance have been assessed against existing evidence. The findings are useful to stakeholders involved in the design of covered car parks to allow a balanced approach to their fire safety requirements.

Development of test methods for fire-retardant coatings of steel engineering structures during operation

Introduction. Prediction of the durability of flame-retardant coatings of steel engineering structures and preservation of their performance during operation remain important research directions. There is a lack of normative documents in the field of fire protection, regulating the process of testing of flame-retardant coatings during operation, as well as determination of their durability (service life).Aim. To develop test methods for determining the resistance of flame-retardant coatings of steel engineering structures exposed to climatic factors, preservation of their fireproof and anti-corrosion properties during operation.Materials and methods. Test specimens included 600 x 600 x 5 mm plates made of 08kp and 08ps sheet steel according to State Standard 16523-97 and State Standard 9045-93 with a flame-retardant agent applied on the front side.Results. Methods for testing thin-layer intumescent and structural flame-retardant coatings during operation are proposed. The methodology of accelerated climatic testing of specimens coated with thin-layer intumescent flame-retardant coatings (flame-retardant paints) corresponds to State Standard 9.401-2018. These coatings are inherently high-solid paint materials. A new methodology, sequence, and modes of testing are developed for structural flame-retardant coatings. The subsequent assessment of fireproof properties of coatings and their preservation is carried out by the methods of fire protection efficiency according to State Standard R 53295-99 and the methods of thermal analysis. These methods imply comparison of the characteristics of the initial flame-retardant coating and those obtained after sample aging. The preservation of fireproof properties by thin-layer intumescent and structural coatings is additionally evaluated by the intumescence coefficient and the change in thermal conductivity, respectively.Conclusions. Test methods for flame-retardant coatings of steel engineering structures during operation are developed. Threshold levels of changes in their properties are established. After accelerated climatic tests, fire protection efficiency should not decrease by no more than 20 %. For structural fire protection, an increase in thermal conductivity by no more than 5 % is permitted. For thin-layer coatings, the arithmetic mean value of the intumescence coefficient should not decrease by no more than 30 % of the initial value.Implications. The developed methods were used in the preparation of a draft national standard of the Russian Federation “Steel engineering structures with fireproof coatings. Test methods for anticorrosion properties and resistance to climatic factors during operation” to ensure regulatory fire safety requirements for these structures.

ИСПОЛЬЗОВАНИЕ ПОКАЗАТЕЛЯ УЯЗВИМОСТИ КРИТИЧЕСКОГО ЭЛЕМЕНТА ДЛЯ ОЦЕНКИ СНИЖЕНИЯ ПОЖАРНОГО РИСКА

Рассмотрено использование интегрального показателя уязвимости критического элемента (ПУКЭ) для оценки снижения пожароопасности и разработки соответствующих мер безопасности. Представлен методический подход к определению ПУКЭ и оценке пожарного риска на основе этого показателя. ПУКЭ представляет собой комбинацию вероятности возникновения пожара и последствий, которые он может вызвать. Чем выше значение ПУКЭ, тем более уязвим критический элемент и, следовательно, выше риск возникновения пожара. Отмечена важность данного подхода и приведены примеры его применения в различных сферах деятельности. In accordance with the requirements of the Federal Law 256-FZ “On the safety of fuel and energy complex facilities” dated 21 July 2011 it is necessary to analyze the vulnerability of critical elements of the facility from an act of unlawful interference. The facilities associated with the processing of oil and petroleum products are the ones with the largest fires among all critical infrastructure facilities. Thus, it is most important to calculate and reduce the fire risk at such facilities. According to Federal Law 123-FZ “Technical Regulations on Fire Safety Requirements” dated 22 July 2008, fire risk is a measure of the possibility of implementing a fire hazard situation and its consequences for both humans and material values. However, the methodology for calculating the fire risk at industrial facilities stated in the Order of EMERCOM of Russia No. 404 dated 10 July 2009 “On approval of the methodology for determining calculated values of fire risk at production facilities”, takes into account only the consequences for humans. So there is introduced a new concept – “integral normalized index of fire vulnerability” (hereinafter referred to as “fire vulnerability index”). Goals and objectives. Calculate the fire risk value, as well as the value of the “fire vulnerability index”. Elaborate the measures to reduce fire risk. Analyze the effectiveness of elabirated measures. Methods. To calculate the fire risk value, there were used the data obtained during the categorisation of the hazardous production facility. On the basis of these data, a "vulnerability analysis" was carried out with respect to critical elements of the facility. For the discovered "vulnerable critical element" the value of fire risk and "value of fire vulnerability" was calculated. The compensating measures were developed in accordance with Federal Law 123 and also fire risk and "value of fire vulnerability" were recalculated. Results and their discussion. The fire risk calculations show that there is an exceedance of the permissible value at the object under study. According to the results of categorisation, the facility was assigned an "medium" hazard category. The reduction of the fire risk value after the developed measures was 97 %. And the reduction of the "fire vulnerability index" was 69.8%. Conclusion. The developed measures allowed significantly reducing the fire risk value, which indicates a strict necessity for their installation and presence at the studied facility. Based on a reduction in “fire vulnerability”, the financial department of the enterprise can more objectively form a financial reserve. And based on “fire vulnerability”, it is possible to more accurately form insurance payments for facilities with a “high” potential hazard category.
