FIELD: fire-fighting equipment.
SUBSTANCE: invention relates to a method and system for preventing and/or extinguishing fire in a closed target area (101) in a vehicle, in particular in track vehicle (100) having a central compressed air source (102) for supplying compressed air to circuit (114) consumers, if required. Proposed method comprises feeding compressed air into buffer tank (130) for compressed air and compressed air fed into gas separation device (140) from compressed air buffer tank (130). Gas mixture enriched with nitrogen is supplied to output (140b) of the gas separation device (140), and the gas mixture is introduced into target zone (101), if required. In order to provide supply of compressed air, inlet (130a) of buffer reservoir (130) for compressed air is at least temporarily connected by fluid medium to outlet (102a) of central source (102) of compressed air so that compressed air can be supplied to buffer tank (130) for compressed air.
EFFECT: fluid connection is provided between central compressed air source (102) and compressed air buffer tank (130) if consumer circuit (114) does not extract compressed air from central compressed air source (102).
