This study deals with ensuring fire safety in buildings of a cluster animal industrial complex by optimizing legislative measures and analyzing factors that affect the quality and reliability of the results of calculating fire risk. The research involved the following methods: expert assessment; calculating individual fire risk; modeling evacuation of people in the form of an individual flow model of human traffic. The conceptual features of the complex's buildings required developing the design and technical solutions that would reduce inefficient costs on the one hand, and, on the other, would ensure meeting fire safety requirements. The individual fire risk for employees of the asset to be protected is 2.91 ×10-7 per year-1 (0.291 ×10-6 per year). That is, it does not exceed the characteristic value established by Federal law No. 123-FZ dated 22.07.2008 'Technical regulations on fire safety'. After the introduction of the fire risk assessment system at the legislative level, the owners of objects have received the opportunity to optimize the cost of fire safety and the required level of human safety.

The article is devoted to the study of fire safety based on the calculation of fire risks in the objects of trade and cultural purpose in the event of a conditional fire. The conditions for safe evacuation of people in the event of a fire in the areas of the object, characterized by a significant concentration of people are substantiated. In both cases, a differential (field) fire model was used to calculate the dynamics of fire hazards. The formation of a three-dimensional computational domain was carried out in the Pyrosim program. In the article, the calculations of the dynamics of fire hazards were carried out, the measurements of which were carried out in seven conventionally accepted comparison points (locations of sensors-meters OFP). The estimated time to evacuate people is generally determined by simulating the movement of people before going outside. The choice of the method for determining the estimated time of evacuation was made taking into account the specific features of the space-planning solutions of the building, as well as the features of the contingent.  As a model for calculating the evacuation time, an individual flow model of human traffic was used. Calculations for the considered scenarios of fire in the area of cinemas and in the area of the shopping hall showed that the individual fire risk for people   is 8.94·10-8 and 2.63·10-7 year-1, respectively, that is, does not exceed the normative value. The results of the individual fire risk assessment can be used to confirm the compliance of the object of protection with fire safety requirements.

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.

В рамках развития методологии отнесения объектов защиты к определенной категории риска в области пожарной безопасности на основе оценки базового показателя тяжести потенциальных негативных последствий пожаров для объектов защиты, однородных по видам экономической деятельности и классам функциональной пожарной опасности, разработана динамическая модель определения или изменения категории риска объекта в зависимости от индекса индивидуализации подконтрольного лица. Это позволяет определить категорию риска либо принять решение об изменении ранее присвоенной категории риска для конкретного объекта защиты из группы с учетом индивидуальных социально-экономических характеристик данного объекта защиты, оказывающих влияние на уровень обеспечения его пожарной безопасности, а также учесть соблюдение на объекте защиты обязательных требований пожарной безопасности на основе информации об этом объекте, имеющейся в распоряжении органа государственного пожарного надзора. There was developed the dynamic model for determining or changing the risk category of the object according to the individualization index of the controlled person. The aforesaid model was elaborated in the context of development of the methodology for assigning objects of protection to a certain risk category in the field of fire safety, based on the assessment of basic severity index of potential negative consequences of fire for objects of protection that are homogeneous both in economic activities and in functional fire hazard categories. This allows to determine the risk category, or decide to change the previously assigned risk category for a particular object of protection from a certain group, taking into account the individual socio-economic characteristics of this object of protection, affecting the level of its fire safety. This also allows to take into account the compliance with mandatory fire safety requirements at the object of protection on the basis of information about this object that is available to the state fire supervision body.

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.
