Existing volunteer air raid precaution associations were forced to merge with RLB.

RLB was dissolved by the Allied Powers after the end of World War II.

Its successor in the Federal Republic of Germany was the Bundesverband für den Selbstschutz.

The local level was formed around air raid wardens and operated in small first intervention squads.

The training include fire fighting, protection against chemical weapons, communication procedures and preparation of houses and apartments against air raids.
