The risk of failure of various modules (residential, warehouse, household, energy supply, etc.) in case of fires and the impact of this on the target functions and personnel of objects is shown. The concept of survivability of Arctic objects in the event of fires is introduced and the main indicators of survivability are formulated. The necessity of maximum operational containment and extinguishing of fires at the above-mentioned objects in order to ensure the necessary level of their survivability is justified. Keywords Arctic objects, infrastructure, fire, survivability 1. Introduction Arctic modules of various functional purposes have two common features: a) high energy saturation 1 (the ratio of circulating power to volume, an order of The current stage of development of our country magnitude greater than similar rooms in a temperate involves the intensive development of the Arctic climate); b) reduced fire resistance [3, 4]. Zone (AZ) and the regions of the Far North (FN). The consequence of this is the need to create a sustainable transport infrastructure – the reconstruction and construction of sea and river ports, airports, land transport highways, etc. [1-3]. It is planned to create a network of various objects in the AZ and on the FN - weather stations, communication systems, research stations, power facilities, etc. The extremely difficult conditions of the Arctic and the North (low temperatures, winds, snow zones, permafrost) suggest the modularity of the structure of objects (Figure. 1), which allows it to be developed and expanded with modules of various functional a purposes – residential, warehouse, administrative, industrial, energy supply, etc. 2.

Data on the accident rate of objects in AZ are - the inability to provide operational assistance shown in Table 1. As statistics show, fires and from outside due to limited transport accessibility explosions pose the greatest threat to Arctic objects. (long distances between objects, snow drifts, non- A feature of the fire in the Arctic module is the flying weather, etc.) and remoteness from large rapid growth of hazardous factors (HFF) [4] due to settlements and Arctic rescue centers (ARC) of the limited volume and its high energy saturation. EMERCOM of Russia; Extinguishing the fire with the use of well-known - a limited number of personnel (each member of tactics [8] by the links of the gas and smoke the staff is required to possess several additional protection service (GSPS) is complicated: specialties, including firefighter and paramedic). - low outdoor air temperatures and the exceptional As a result, a fire can lead to significant damage complexity of using water [9]; (Figure 2) [10] up to the loss of the functional purpose of the object and a threat to its personnel. Table 1 Data on accidents at facilities in AZ Accidents and emergencies Ratio Collapses and fires in residential and administrative buildings 21-39% Explosions and fires of technological equipment 18-39% Transport accidents 25-32% Accidents on utility networks and life support systems 7-15% Accidents with the release of toxic and chemically dangerous substances 8-12% Pipeline accidents 4-8% Figure 2: Structure of fire damage at a modular Arctic facility This poses the task of developing a fundamentally the fire. Arrived firefighters enter the module from new method of fire containment and extinguishing in the fan side and extinguish it with primary fire the module, which does not require the use of water extinguishing means (PFEM) under the protection of and the use of expensive Arctic fire equipment. Also a low-temperature jet – as calculations and important requirements are high efficiency (the experiments have shown, the HFF will be removed module can be irretrievably damaged after a few from the gap between the fire source and the fan [13, minutes of free development of the fire) and safety 14], firefighters will be able to work even without for the participants of extinguishing. respiratory and visual protection. To speed up the With the participation of the author of the article, extinguishing by other participants of the such a method was proposed, justified and patented extinguishing, snow can be dosed on the fan from the [11, 12]. Its essence is that the module is equipped outside. In fact, this is a new tactic for extinguishing with a built-in fan at the end, which is closed by a fires in the modules of Arctic objects. hatch in the initial position, and another normally As an explanation, Tables 2-4 show the closed hatch is located in the opposite end of the comparative effects of extinguishing fires by known module. If a fire occurs, the hatches are opened, and and proposed methods on the example of some types the fan turns on, blowing the volume of the module of modules – residential, economic and energy- with external low-temperature air. This leads to a supplying. Taking into account the above, it seems sharp decrease in the average volume temperature, appropriate to introduce a new concept of flame failure, removal of HFF from burning module, "survivability of a modular Arctic object in case of slowing down the combustion and thereby containing fire". By analogy with the well – known formulation of Admiral S. O. Makarov: "the survivability of a modular Arctic object in a fire is the ability of an ship is the ability of a ship to fight when some of its object to perform its functions when some of its parts are damaged by the enemy", the following modules are damaged by fire". formulation can be proposed: "the survivability of a Table 2 Comparative effect of the new tactics of extinguishing the residential module Conditions Extinguishing Damage Influence on the object fires (%) The staff is Application PFEM, arrival of the duty shift Minor, minor repairs in a waking department are required Minor state application of the PFEM, switching on the (up to 5%) purge system There are Arrival of the duty shift department, Significant, module Average, it is necessary to no staff, extinguishing by GSPS, ERO links failure relocate people (15-20%) the APS Switching on the purge system, eliminating Minor, minor repairs Minor has worked combustion by the forces of the duty shift are required (up to 5%) department People in a Possible poisoning by combustion products, Medical assistance is Significant, some specialists state of extinguishing by GSPS links, conducting required, the module is are lost, urgent medical care sleep ERO out of order is required (50-80%) Switching on the purge system, evacuation, Minor, minor repairs Minor elimination of combustion by the forces of are required, there are (up to 5%) the duty shift department no victims ERO – emergency rescue operations Table 3 Comparative effect of applying a new extinguishing tactic in case of a fire in a food hall Conditions Extinguishing Damage Influence on the object fires (%) Short circuit The use of PFEM personnel, Medium, requires module Average, temporary in the extinguishing by GSPS links repair, repair (replacement) of transition to dry rations electrical equipment (20-30%) equipment of Switching on the purge system, Minor, minor repairs are Minor, power schedule the brew eliminating combustion by the forces required, the main equipment shift house of the duty shift department is preserved (up to 15%) Grocery Arrival of the duty shift department, Some of the products are Significant, power warehouse extinguishing with GSPS links, damaged, the warehouse is out outages, food delivery is without conducting ERO of order required (50-70%) permanent Switching on the purge system, ERO, Minor, products are saved, Minor jobs elimination of combustion by the minor repairs are required (up to 15%) forces of the duty shift department Table 4 Comparative effect of the new tactics of extinguishing the energy module Conditions Extinguishing Damage Influence on the object fires (%) Short circuit Disconnection of electrical equipment, Significant, requires repair or Partial loss of functions in the use of PFEM by personnel, replacement of equipment, due to de-energization of electrical extinguishing and conducting ERO by partial failure of the module the object, deterioration panel, cable GSPS links of heating (40-60%) industry Disconnecting electrical equipment, Minor, minor repairs are Minor, temporary power switching on the purge system, required, the module is saved outage eliminating combustion by the forces (up to 10%) of the duty shift department Fuel leakage The threat of a flash or explosion, Significant, requires repair or Temporary de- and ignition disconnection of the fuel supply, the replacement of equipment, energization of the object use of PFEM by personnel, partial failure of the module (30-50%) extinguishing and conducting ERO by GSPS links Switching off the fuel supply, Minor, minor repairs are Minor, temporary power switching on the purge system, required, the module is saved outage eliminating combustion by the forces (up to 10%) of the duty shift department Scheduled Disconnection of electrical equipment, Significant, requires repair or Temporary de- or application of PFEM, extinguishing replacement of equipment, energization of the object unscheduled and conducting ERO by GSPS links partial failure of the module (30-50%) repairs, Switching off the fuel supply, Minor, minor repairs are Minor, temporary power welding switching on the purge system, required, the module is saved outage work eliminating combustion by the forces (up to 10%) of the duty shift department At the same time, the impact of a fire on the Arctic.
