1. Способ повышения пожарной безопасности внутри герметичных обитаемых объектов, преимущественно подводных лодок, включающий использование кислородно-азотной среды с содержанием кислорода 14±1 об.% и поддержание повышенного давления воздушной среды на все время герметизации таким образом, чтобы парциальное давление кислорода в среде соответствовало нормоксическому и составляло 20-21 кПа, а давление газовоздушной среды соответствовало 150 кПа, отличающийся тем, что установленные параметры газовоздушной среды (ГВС) регулируют для еще большего повышения пожарной безопасности объекта на заданное время, после получения сигнала от средств предпожарного предаварийного контроля о переходе источника пожарной опасности в предаварийное предпожарное состояние, путем снижения давления ГВС и, соответственно, снижения парциального давления кислорода при сохранении концентрации кислорода, либо путем снижения концентрации кислорода, и, соответственно, снижения парциального давления кислорода при сохранении давления ГВС, либо сочетанием этих обоих способов, причем устанавливаемые параметры ГВС в течение всего совокупного времени регулирования не должны наносить ущерб здоровью или значимо снижать работоспособность членов экипажа.1. A method of increasing fire safety inside sealed inhabited objects, mainly submarines, including the use of an oxygen-nitrogen medium with an oxygen content of 14 ± 1 vol.% And maintaining increased air pressure for the entire time of sealing so that the partial pressure of oxygen in the medium matches normoxic and amounted to 20-21 kPa, and the pressure of the gas-air medium corresponded to 150 kPa, characterized in that the established parameters of the gas-air medium (DHW) are regulated for even greater to increase the fire safety of the facility for a given time, after receiving a signal from the means of pre-fire pre-emergency control about the transition of the fire hazard source to the pre-emergency pre-fire state, by reducing the hot water pressure and, accordingly, reducing the partial pressure of oxygen while maintaining the oxygen concentration, or by reducing the oxygen concentration, and, accordingly, reducing the partial pressure of oxygen while maintaining the hot water pressure, or a combination of both of these methods, moreover, established d.h.w. parameters during the entire cumulative regulation time should not be detrimental to health or significantly reduce the efficiency of crew members. 2. Способ по п. 1, отличающийся тем, что после герметизации устанавливают начальные параметры газовоздушной среды, характеризующиеся содержанием кислорода около 14 об.%, давлением ГВС около 140 кПа, парциальным давление кислорода около 19,2 кПа и остальными параметрами, как для нормальных условий, а при регулировании, в одном варианте, понижают давление ГВС от 140 кПа до значений 101-120 кПа с сохранением процентного содержания кислорода на уровне 13-14 об.% и снижением парциального давления от 19,2 кПа до 13,8-16,8 кПа, или, в другом варианте, поддерживают давление ГВС на первоначальном уровне около 140 кПа и при этом снижают концентрацию кислорода до 11-12 об.% при давлении ГВС 140 кПа, или около 15,5-17,2 кПа парциального давления кислорода при нормальных условиях, на время, как правило, 30-60 минут, или сочетают оба вышеприведенных варианта способа таким образом, чтобы не нанести ущерб здоровью и работоспособности членам экипажа, а после идентификации источника пожарной опасности восстанавливают начальные параметры газовоздушной среды.2. The method according to p. 1, characterized in that after sealing the initial parameters of the gas-air medium are established, characterized by an oxygen content of about 14 vol.%, A hot water supply pressure of about 140 kPa, a partial oxygen pressure of about 19.2 kPa and the rest of the parameters, as for normal conditions, and when regulating, in one embodiment, lower the DHW pressure from 140 kPa to 101-120 kPa while maintaining the percentage of oxygen at 13-14 vol.% and lowering the partial pressure from 19.2 kPa to 13.8-16 , 8 kPa, or, in another embodiment, support pressure DHW at the initial level of about 140 kPa and at the same time reduce the oxygen concentration to 11-12 vol.% at a hot water pressure of 140 kPa, or about 15.5-17.2 kPa of the partial pressure of oxygen under normal conditions, for a while, as a rule, 30-60 minutes, or combine both of the above versions of the method in such a way as not to damage the health and performance of the crew members, and after identifying the source of the fire hazard, the initial parameters of the gas-air environment are restored.
