IDENTIFICATION OF FACILITIES
Buildings and magazines, including open storage
sites that contain ammunition, explosives, or chemical
and inert components, are marked according to a
standard system of identification so you can rapidly
identify the hazards associated with their contents. This
identification and numbering system is used in addition
to any other numbers on the buildings. These standard
identification markings are stamped out over other
markings, if present.
The standard identification
system consists of the magazine designator and the
symbol indicator.
The magazine designator is a three-group symbol,
composed of numbers and letters. It identifies a
magazine by location of the magazine group, the
number of the magazine within the group, and the type
of magazine construction. The magazine group
number, the type of magazine and capacity letter(s), and
the magazine sequence number form the three-group
symbol that makes up the magazine designator.
Magazine Group Number
The magazine group number is the first number of
the magazine designator symbol. It shows the magazine
group in which the magazine is located Each physically
separated group of magazines or, at smaller stations,
each noncontiguous magazine area is assigned a
number, making it easy to rapidly and easily identify the
group. The group numbers begin with 1 and continue
in ascending numerical order. If only one magazine
group exists, the number 1 is used. For example, the
numeral 4 in the first position of the magazine
designator 4XTX4 indicates that this magazine is
located within magazine group 4.
Magazine Type and Capacity Letter(s)
The magazine type and capacity letter(s) shows the
type and capacity of the magazine. For this reason,
magazines of certain sizes are assigned a letter
