f. Quantity-Distance: The quantity of explosive material
and distance separation relationship that provide defined types
of protection.
g. Donor Magazine:
Is a magazine which produces the
damaging output.
h. Receiver Magazine: Is the magazine away from the donor
source which requires protection.
i. Barricaded: Magazines with intervening barrier, natural
or artificial, of such type, size, and construction as to limit
in a prescribed manner the effect of an explosion on a nearby
magazine.
j.
Unbarricaded:
Magazines without an intervening barrier.
1-3. Separation Distances of Magazines. Separation distance
from magazines, commonly referred to as quantity-distance (Q-D),
governs many aspects of a project. Stated simply, the more
explosive material concentrated at one place, the farther that
place has to be from a potential target. AR 385-64 contains
tables equating amounts of explosives to the distance that they
must be separated from other magazines, other ammunition and
explosives handling facilities, public roads, and inhabited
buildings. Orientation effects on intermagazine distance can
also be found in AR 385-64. The following table and Figure 1
show the Q-D requirements between standard magazines:

1-4. Magazine Grouping Concepts. Magazine grouping concepts are
provided in Figures 2 and 3. These concepts are typical layouts
found on most Army installations. Magazines may be placed in one
row or multiple rows. Siting is generally side-to-side and
