accidental explosion. The only restriction imposed upon the arrangement of groups of

modules is that cell openings will not be faced toward each other unless they are barricaded,

or meet the standard quantity-distance criteria for unbarricaded above-ground magazines.

(7). The spacing required between cells in a module shall be determined by considering each cell

as a potential explosive site. The explosive content of the cell requiring the greatest distance

shall be the minimum separation between the adjacent cells under consideration. The

separation distance between cells shall be measured from the nearest edge of the stack of

munitions in one cell to the nearest edge of the stack of munitions in the adjacent cell. Figure

9, page 12 contains spacing requirements between cells for specific quantities of explosives

per cell. If cell explosives loading is established for weights other than those shown,

minimum distances between stacks shall be determined by applying the distances given by

the formula: d = 1.1(W 1/3), i.e., distance = 1.1 times the cube root of the net weight of

explosives in pounds.

(8). The spacing required between modules shall be computed as follows:

(a). Each cell of each module will be considered as a potential explosive site. The minimum

distance between the explosive stacks in each cell and the nearest stack in the adjacent

module shall be determined by applying the distances given by the formula: d = 2.5(W

1/3), i.e., distance = 2.5 times the cube root of the net weight of explosives in pounds.

(b). The quantity of explosives in that cell of either module which results in the greatest

separation distances will determine spacing between the modules being considered.

Distance will be measured from the nearest edge of the munitions stack in the controlling

cell in the module to the nearest edge of the stack of munitions in the adjacent module.

See Figure 9, page 12 for module separation for specific quantities of explosives per cell.

(9). The height and length of the barricade shall be determined as follows:

(a). To determine height, establish a reference point at the top of the far edge of one of the

two stacks under consideration between which the barricade is to be constructed. This

reference point, if the tops of the stacks are not the same elevation, will be on the stack

whose top is at the lowest elevation. Draw a line from the reference point to the highest

point of the other stack. Draw a second line from the reference point forming an angle of

2 degrees above the line. You can now determine the necessary height of the barrier.

Refer to Figure 6, page 9 to compute the height of a barricade.

(b). To determine the length, extend the barricade 3 feet, exclusive of the end slope, beyond a

line between the extremes of the two stacks of ammunition or buildings to be protected.

Refer to Figure 7 to determine the length of a barricade.

NOTE: The modular storage method should only be used if the quantity- distance requirements of the other field

storage systems cannot be met due to security, real estate, or operational limitations. This system will store a

maximum of 2,000,000 pounds net explosive weight (NEW) per module or 250,000 pounds NEW per cell. This

system can be used only when the request is approved by the major command.
