Table 12-7.Magazine Designators for Fire Hazard of Powder (Bulk or Semifixed Ammunition), Pyrotechnics, Ignition Fuzes and
Primers, Small Arms, Smoke Drums, and Explosive-Loaded Chemical Ammunition
Table 12-8.Magazine Designators for Fragment Hazard of Projectile and Fixed Ammunition
designation as indicated in tables 12-6, 12-7, 12-8, and
12-9. To show the type of magazine, for example, the
letter T is added if the magazine is earth-covered and
barricaded If the magazine is earth-covered but not
barricaded, the letter C is added. If the magazine is not
earth-covered but is barricaded, the letter S is added.
Therefore, in the magazine designator 4XTX4, the letter
X in the second position indicates that the magazine size
is miscellaneous or nonstandard, and it is normally used
for storing high explosives. Also, the normal explosive
storage limit depends on the magazines size, location,
and type of construction.
The explosive limits contained in tables 12-4
through 12-7 are maximum capacities, They are based
on magazine design and construction characteristics.
These limits are further subject to the Q-D
considerations discussed previously. Additional
limitations are shown in the magazine designator. When
the Q-D relationship, as indicated in the tables, doesnt
permit using the explosive capacity design of a standard
magazine because of insufficient separating distances,
the letter X, Y, or Z is added to the designator. These
letters indicate the magazine contains mass detonation
hazards, mass fire hazards, or fragment-producing
hazards, respectively. For example, in the magazine
