  • Extinguishing systems with extinguishing containers in which elastic extinguishing agent containers are arranged, are known.
  • DE 946 684 describes a fire extinguisher with a pressure vessel in which a bag is arranged, in which a foam-producing agent is located. If an overlying gas cartridge is opened, this leads to the fact that the bag is destroyed and extinguishing liquid exits into a quenching tube. The fire extinguishing process thus requires the destruction of a bag by mechanical forces.
