designed to withstand the dynamic forces from an explosion in an
adjacent magazine and, therefore, are a critical element of the
magazine design. These doors do not provide resistance to the
effects of an explosion within the magazine.
3-5. Utilities and Power. The only utility usually required at
a magazine site is electricity. This power is needed for lights
at individual magazines, for perimeter lighting, and possibly for
operation of electronic security equipment.
3-6. Road Network. The road network is not part of the standard
design. The user must provide service to each magazine as part
of the site adaptation process. vehicle size and wheel loads
should be stated in the project development documentation.
Forklift loads are usually the most critical. Two-lane roads are
seldom required, except at the site entrance.
3-7. Aprons. Each magazine has an apron in front of its door to
allow for loading and unloading. The aprons slope away from the
door for drainage. Changes to the apron configuration to suit
user needs will not compromise the pre-approved status of the
standard design.
3-8. Retaining Walls (Wing walls). Retaining walls are for the
sole purpose of retaining the earth fill away from the magazine
doors. Construction type may vary from reinforced concrete,
precast concrete to reinforced-earth systems. The slope of these
walls should be 2 horizontal to 1 vertical.
3-9. Ventilation. Standard magazine designs usually include
provisions for ventilation. Ventilation is provided by louvered
openings in the headwall and ventilator stacks at the rear walls.
Magazines intended for weapons storage containing certain active
materials must be ventilated. Otherwise, louvers and ventilators
are optional. Their necessity and size should be determined
during the site adaptation based on material to be stored and
geographical location.
3-10. Security. The security at a magazine complex is an
integration of physical measures, equipment, and operational
procedures. procedures are left to the using agency, since they
are beyond the control of the designer. Limited security
features included in the standard designs are high security hasp
requirements at magazine doors (MIL-H-29181), steel bars at
openings, shrouded ventilators, and basic provisions, i.e., steel
conduit for electronic security equipment.
3-11. Cathodic protection. Cathodic protection may be required
for steel-arch magazines and should be considered in areas where
