Risk Categories

Normative legal acts of the Russian Federation establish that the criteria for assigning control objects to the categories of risk of causing harm should be formed based on the results of the assessment of the risk of causing harm. In the developed countries of the world, as a rule, the distribution of objects of control by risk categories and the substantiation of the frequency of their inspections are carried out depending either on the point risk assessment, or on the number and importance of the violations of mandatory fire safety requirements revealed during the inspection of the object of control. The purpose of this work is to substantiate the frequency of scheduled inspections of the objects of control by the state fire supervision bodies depending on whether the objects of protection belong to a particular category of risk of causing harm. As a criterion for assigning control objects to various categories of risk of causing harm, it is proposed to use the risk of causing harm (damage) as the result of fire in the buildings of various classes of functional fire hazard, which is understood as the product of the probability of fire occurrence, the probability of causing socio-economic harm (damage) as the result of fire and the value terms of socio-economic harm (damage). A mathematical model was developed to determine the risk of causing harm (damage) as the result of a fire in a building, and an assessment of its values for the buildings of various classes of functional fire hazard is given. Distribution of the buildings by categories of risk of causing harm (damage) was carried out depending on the calculated value of the risk of causing harm. It is shown that the distribution of control objects by risk categories significantly depends on the degree of detail in the fire record card of the characteristics of the building in which the fire occurred. The optimal terms for carrying out scheduled inspections of the objects of control are proposed depending on the category of risk to which they are assigned. Proposals are formulated concerning the improvement of the risk-oriented approach in the activities of the state fire supervision bodies of the EMERCOM of Russia.

The article considers a wide range of questions pertaining to possible and applicable harmonization of business accounting and the SNA which would, if implemented, facilitate the improvement of the information base for the compilation of national accounts and consistency of analysis of economy at micro and macro levels. The authors note that total harmonization of the two systems of information cannot be achieved due to diff erences in their key objectives. The harmonization of selected indicators and classifi cation, however, is possible and useful. In this context, the views on this matter of internationally-recognized national accounts experts, such as R. Ruggles (the USA) and F. Bos (the Netherlands), are commented on. A comparative analysis of concepts and defi nitions of some indicators of both systems is presented in the article. In particular, the diff erences between the income defi nitions. For instance, it is noted that the SNA defi nition of income is based on the concept developed by J. Hiсks and it excludes income from sales of assets and holding gains, whereas in business accounting this method is not adopted. The diff erences between two systems in defi nitions of sale of output, input, profi t and methods of valuation of indicators are also described in the article. The authors substantiate the possible directions and sequence of individual steps to the harmonization of the SNA and business accounting in the Russian Federation. They emphasize the need for close interaction between Rosstat and the Ministry of Finance of Russia in carrying out this vital work, which is necessary for creating single information, statistical and methodological space in Russia, to improve the quality of statistics and accounting, analytical work in general and management decisions.

Abstract The fire load is an integral part of the fire hazard definition. Reducing this load is one of directions to fight fires in transport. To study the physicochemical processes and thermal effects occurring as a result of thermal decomposition of wood fire-proofed by retardants like BAN, OK-GF, OK-DS (OK-GFM), SPAD-0 and their chemical compositions, we used the methods of differential thermal analysis, thermogravimetry, and derivative thermogravimetry. In addition, to study the intensity of physicochemical combustion processes, tests to control changes in woodwork masses and temperature at the top of pipe depending on the duration of combustion of the samples and the consumption of fire retardants were conducted. Fire retardant compositions like OK-GF, OK-DS, Pirilax biopyrene at the consumption of 0.1 kg / m2 ensure flame and combustion resistance of the wood. The analysis of the research results confirmed the possibility of assigning to wood structures of a lorry’s body of the group 1 of flame and combustion resistance. Using the above fire retardants and their compositions in the treatment of lodgment elements and runners significantly affects the possibility and duration of the combustion process of a lorry. This was tested by means of an artificial fire source method (without chemical treatment, the burning time does not exceed 50 minutes). This significantly improves post-collision safety of vehicles with an increased fire load in terms of fire resistance because of using the natural gas as a motor fuel.

Natural gas is widely used in sequentially port fuel injection engine to meet stringent emission regulation. Lean burn operation is one of the ways to improve spark-ignition engine fuel economy. The instability in the combustion process of the lean burn engine is one of the major challenges for engine research. In this study, the performance and combustion characteristics of a lean burn sequential injection compressed natural gas (CNG) engine were investigated numerically using computational fluid dynamics (CFD) modeling over a wide range of air/fuel equivalence ratio. A detailed chemical kinetic mechanism was used for natural gas combustion along with laminar flame speed model to capture lean burn operating condition within the combustion chamber. Combustion pressure, indicated mean effective pressure (IMEP), and heat release were analyzed for performance analysis, whereas flame development angle (CA 10), combustion duration, thermal efficiency were taken for combustion analysis. The results show that on increasing air/fuel equivalence ratio at a given spark timing, IMEP decreases as the lean burn mixture produces less amount of gross power output due to insufficient available energy. Moreover, lower burning velocity characteristic of natural gas extends the combustion duration, where a substantial amount of total energy released after top dead center. It is also seen that optimum spark timing (MBT) for maximum IMEP advances with an increase in air/fuel equivalence ratio due to late ignition timing under lean burn condition. CFD model successfully captures the effect of dilution to illustrate the considerations to design future combustion engine for spark ignited natural gas engine.

The expediency of using vehicles of liquefied petroleum gas as a motor fuel, as com-pared with traditional liquid motor fuels, in particular with diesel fuel, is shown. The advantages of converting diesel engines into gas ICEs with forced ignition with respect to conversion into gas diesel engines are substantiated. The analysis of methods for reducing the compression ratio in diesel engines when converting them into gas ICEs with forced ignition has been carried out. It is shown that for converting diesel engines into gas ICEs with forced ignition, it is advisable to use the Otto thermo-dynamic cycle with a decrease in the geometric degree of compression. The choice is grounded and an open combustion chamber in the form of an inverted axisymmetric “truncated cone” is developed. The proposed shape of the combustion chamber of a gas internal combustion engine for operation in the LPG reduces the geometric compression ratio of D-120 and D-144 diesel engines with an unseparated spherical combustion chamber, which reduces the geometric compression ratio from ε = 16,5 to ε = 9,4. The developed form of the combustion chamber allows the new diesel pistons or diesel pistons which are in operation to be in operation to be refined, instead of making special new gas pistons and to reduce the geometric compression ratio of diesel engines only by increasing the combustion chamber volume in the piston. This method of reducing the geometric degree of compression using conventional lathes is the most technologically advanced and cheap, as well as the least time consuming. Keywords: self-propelled chassis SSh-2540, wheeled tractors, diesel engines D-120 and D-144, gas engine with forced ignition, liquefied petroleum gas (LPG), compression ratio of the internal com-bustion engine, vehicles operating in the LPG.
