1. A method for preventing and/or extinguishing a fire in an enclosed target area in a vehicle, wherein the vehicle comprises a central compressed air source for supplying compressed air to a load circuit, and wherein the method comprises steps of:

  • providing a compressed air buffer tank in the vehicle for buffering the compressed air supplied by the central compressed air source;

    providing a supply of the compressed air from the central compressed air source of the vehicle in the compressed air buffer tank of the vehicle;

    supplying the compressed air from the compressed air buffer tank to a gas separation device as needed;

    temporarily storing the compressed air provided by the central compressed air source in the compressed air buffer tank;

    performing a gas separation in the gas separation device and providing a nitrogen-enriched gas mixture at an outlet of the gas separation device; and

    introducing the nitrogen-enriched gas mixture into the enclosed target area as needed, wherein in order to provide the supply of compressed air, an inlet of the compressed air buffer tank is at least intermittently fluidly connected to an outlet of the central compressed air source wherein the compressed air can be supplied to the compressed air buffer tank, and wherein a fluid connection between the central compressed air source and the compressed air buffer tank is provided when the load circuit is not drawing any of the compressed air from the central compressed air source.
