CHAPTER I
INTRODUCTION
1-1. General. An important element in selecting storage
magazines for construction is determining the type of magazine to
be used and the siting requirements. AR 385-64 provides clear
guidance in this regard. An earth-covered magazine is not
designed to resist the damaging effects of its own exploding
contents. It is accepted that the donor magazine will be
demolished if an internal explosion occurs. Earth-covered
magazines are utilized primarily to prevent propagation of an
explosion within an adjacent (receiver) magazine. During the
design phase, and prior to construction, site plans and non-
standard magazine drawings must be submitted to the DDESB for
review in accordance with AR 385-60 to assure that the proposed
project meets explosives safety standards. only the drawing
numbers of standard magazines need be submitted with the site
plan since the construction of such magazines are preapproved by
the DDESB.

Definitions.
a. Magazine: Any building or structure, except an
operating building, used for the storage of ammunitions and
b. Standard Magazine: A preapproved magazine of the
designation listed in AR 385-64. It is a magazine approved for
the storage of 500,000 pounds net explosive weight (NEW) at the
separation distances listed in AR 385-64.
c. Non-Standard Magazine: An earth-covered magazine that
is not listed in AR 385-64 as being approved by the DDESB. These
magazines are limited to a maximum 250,000 pounds NEW at the
separation distances listed in AR 385-64.
d. Hybrid Magazine: A magazine that uses components and/or
modifications from more than one magazine.
e. Intermagazine Distance: This is the minimum permissible
distance between storage magazines. For earth-covered magazines,
this distance is intended to provide reasonable protection
against the propagation of an accidental explosion by airblast
and by fragments.
