High explosive or black powder magazines (Figure 4) are used to store bulk explosives, such as TNT
and black powder. They are spaced 800 feet apart so that if one blows up, the next magazine will not

Primer or fuze magazines (Figure 5) are built exactly the same as high explosive magazines. What
makes them different is the spacing between each magazine, 300-400 feet versus 800 feet. Less
space is required for primer or fuze magazines because primers and fuzes contain much less
explosives than the bulk explosives stored in high explosive or black powder magazines.
Service Magazines and Service Buildings
Service magazines and service buildings are used for intermediate storage of the minimum amount of
explosvies necessary for safe and efficient processing operations. Construction details of such
magazines vary, depending upon local circumstances. However, consideration should be given to the
use of fire-resistant materials or fire-resistant contruction methods.
