It was awarded for meritorious service in German air raid protection. It was open both to members of the
Reichsluftschutzbund, the principal German
air raid precautions organisation, and others involved in this work, including police, fire and emergency services. It was usually necessary to have at least four years service before an award could be made. It was bestowed in two classes: • 1st class: a gilt cross with curved arms. It had a swastika in the centre within a ring bearing the inscription:
Für Verdienst im Luftschutz (For merit in Air Defence). It was awarded for outstanding contributions to air defence in Germany. • 2nd class: a circular medal in grey metal, framed by an oak wreath. In the centre is a swastika surrounded by the inscription:
Für Verdienst im Luftschutz (For merit in Air Defence). It was awarded to those who had made special contributions to air defence. The reverse of both classes bore the date
1938, the year the decoration was instituted. Both classes were worn on the left chest on a light purple ribbon with black-white-red borders. About 200 1st class crosses were awarded. The second class was more common. ==Post war==
