FEATURES OF FIRE-EXPLOSIVE PROPERTIES, EXTINGUISHING METHODS AND SAFE STORAGE CONDITIONS OF AMMONIUM NITRATE
Leonid P. Vogman – Doctor of Technical Sciences, Main Researcher; Alexander V. Ilyichev – Deputy Head of Department – Head of Sector; Vladimir A. Zuykov – Leading Researcher; Evgeny E. Prostov – Senior Researcher; Dmitry V. Dolgikh – Researcher (FGBU VNIIPO EMERCOM of Russia)
The storage of ammonium nitrate usually should be realized in separate single-story warehouse structures of at least II degree of fire resistance in accordance with Russian standards. At the same time, the maximum allowable amount of stored ammonium nitrate within the fire compartment should not exceed 5000 tons, while the simultaneous storage of 25000 or more tons is allowed in the Baltic countries (Latvia, Estonia).
Authors attempt to substantiate the unification of fire safety requirements for ammonium nitrate storage in Russian and foreign standards by calculation and analysis.
COMPARATIVE ANALYSIS OF GOST R AND IMO MSC/CIRC. REQUIREMENTS DETERMINING THE QUALITY OF FOAMING AGENTS USED FOR FIRE EXTINGUISHING BY FOAMS
Sergey N. Kopylov – Doctor of Technical Sciences, Head of Research Center of Automatic Detection and Extinguishing Systems, Senior Researcher; Dmitry S. Shentyapin – Head of Department; Evgeny V. Baranov – Candidate of Technical Sciences, Deputy Head of Department – Chief of Sector; Vladimir V. Grishin – Senior Researcher; Evgeny E. Arkhipov – Senior Researcher (FGBU VNIIPO EMERCOM of Russia)
The article provides the analysis of the GOST R and IMO MSC/Circ. requirements determining the quality of foaming agents used for fire extinguishing by foams. There are presented the differences and similarity of testing approaches, as well as the possibility of equipment usage for testing according to various acting standards in the context of Russian standards and the Maritime Register of Shipping.
FIRE PROTECTION DISTANCES BETWEEN CONSTRUCTIONS OF DIFFERENT PURPOSE. A FIRE IN A WAREHOUSE-TYPE PREMISE.
SERIES OF CALCULATIONS
Alexey S. Baranovsky – Head of Sector; Peter A. Leonchuk – Head of Sector; Stanislav A. Zuev – Candidate of Technical Sciences, Leading Researcher; Valery G. Shamonin – Candidate of Physical and Mathematical Sciences, Leading Researcher, Senior Researcher (FGBU VNIIPO EMERCOM of Russia)
There is performed the series of calculations to estimate the temperature in premise during a fire in ventilation-controlled mode, because the maximum temperature achieves in this case. There is considered the extreme case of heat exchange with the walls of the room – isothermal case. The case of fire in buildings such as warehouses and car parking is examined.
JUSTIFICATION OF THE REQUIRED FIRE RESISTANCE LIMITS FOR BEARING STRUCTURES OF BRIDGEWORKS
Irek R. Khasanov – Doctor of Technical Sciences, Main Researcher (FGBU VNIIPO EMERCOM of Russia); Roman A. Ivashchuk – Fire Safety Engineer (LLC «Zeldorproekt»); Andrey V. Pekhotikov – Chief of Department; Vladimir V. Pavlov – Head of Sector (FGBU VNIIPO EMERCOM of Russia)
The method for substantiating the design solutions of bridgeworks in terms of fire resistance is proposed. The use of regular thermal mode is the basis of the method. The proposed method makes it possible to perform calculations without using high-performance computer tools. The necessity to improve methods for justifying fire resistance limits is substantiated. A brief description of existing methods and the example of calculation are given.
