The Gasplane was introduced on 15 March 1939 by Heeres Mitteilung 210 and initially it had the two official purposes; As a defence against liquid gases dropped out of aircraft and as a blanket to cover poisoned terrain. Army regulations stipulated that the Gasplane had to be carried in the field in addition to the Gasmask and be ready for use.
To use the Gasplane it is removed from the pouch and by holding it by the labels or coloured squares it can be quickly unfolded. The Gasplane is then to be thrown over the head. At this point the user should immediately lie down with their legs pulled up under the Gasplane. When used as a cover over suspected contaminated land the Gasplane was to be placed so a person could lay on it lengthwise.
The standard Gasplane could only be used once, a later variant made for Tropical and Arctic environments could be reused.
