The collective personnel rescue station contains a mobile rigid-frame, all-metal sealed enclosure 1 equipped with an explosion-proof sealed door 2, divided into a vestibule gateway 3 and an inhabited compartment 4 with an airtight bulkhead 5 equipped with a sealed door 6 and an overpressure valve 7. The housing also contains a technical compartment 25 including a system conditioning 11 and an autonomous power supply system 30. The tambour gateway contains a system of a secure entrance 8, including a balloon ramp 14 and an intermediate chamber at 9, at the inlet and outlet of which there are strip curtains 10 and air nozzles 12. An intermediate chamber installed in the airlock 3 contains high-pressure air nozzles 12 connected by an air duct 13 to the balloon ramp 14 and to an external pneumatic network 15. Air conditioning system 11 contains an air regeneration system 16, including regenerative cartridges 17, designed for the time of the protective action of the item, an air filtration system 18 and an air cooling system 19 to comfortable values. The air cooling system includes a water heater 20 connected by a pipe 21 to a water reservoir 22 and an external water supply 23, which improves the reliability of the cooling system. The air conditioning system 11 is also equipped with filters to clean the air from harmful impurities 26. The cooling system 19 also includes a valve 27 for connecting to a water supply 22 and 23 and pumps 28 to ensure the operation of the water heater. The autonomous power supply system located in the technical compartment 25 contains batteries 31, an uninterruptible power supply 32 connected to the batteries 31 and an external power source.

The work of the collective rescue staff is as follows.

In the event of an emergency, the sheltering personnel sequentially enters the collective rescue team through the explosion-proof, airtight door 2. The first person who enters activates the protected entrance system 8 by turning on the air nozzles 12 in the intermediate chamber 9 with the help of the valve 24 to power the curtains 10. All covered, with a delay of 2-3 seconds in the intermediate chamber 9, go into the habitable compartment. Air is supplied to the air nozzles 12 in the intermediate chamber 9 from the external pneumatic network 15 or the balloon ramp 14 through the air duct 13. When the air nozzles are operated in the airlock 3 and the preliminary chamber 9, an air flow is generated directed against the movement of the shelters into the inhabited compartment 4 and excess air is created the pressure in the vestibule gateway 3, the excess of which is vented through the overpressure valve 7. This design blocks the introduction of harmful impurities into the inhabited compartment. After filling the inhabited compartment 4 of the sealed enclosure 1, the sealed doors 2 and 6 are sealed, air from the external pneumatic network is supplied to the inhabited compartment 4. The overpressure in the inhabited compartment is vented through the overpressure valve 7 installed in the sealed bulkhead 5 into the vestibule-lock 3.

If it is not possible to supply air through an external pneumatic network 15, the air conditioning system 11 is turned on, the regeneration system 16 and the air filter 18 are located in the technical compartment 25. Air can be regenerated by passing air through the regenerative cartridges 17, in which carbon dioxide is absorbed and released essential oxygen for breathing. When there are 4 shelters in the inhabited compartment, and when regenerative cartridges 17 are working, the temperature rises, which is discharged by the cooling system 19.

The cooling system is activated by opening the valve 27. Water from the external water supply system 23 through the valve 27 through the pipe 21 enters the water heater 20, and then is discharged by irrigation of the building 1 of the collective rescue staff outside. In this case, the air of the inhabited compartment 4 is cooled in the water heater 20. When the external water supply 23 fails, the cooling system is switched to work with water from the water tank 22 by turning on the pumps 28 that circulate the cooled water in the cooling system 19.

The autonomous power supply system feeds lighting devices 33 from an external power supply 29. If it is impossible to use an external power supply 29, the autonomous power supply system automatically switches power from the batteries 31.

After the time of the protective action of the collective rescue station personnel expires, those who shelter leave it using personal protective equipment, if necessary.
