A series of tests of earth-covered, steel-arch igloo magazines was conducted to determine the minimum spacing distance between adjacent igloos needed to prevent the propagation of an explosion from one magazine to another. It was shown that the distance in feet between the side walls can be determined by multiplying the cube root of the stored explosive weight in pounds by the factor 1.25, and the distance between facing rear walls can be determined by using the factor 1.50.
