c. The center of the OB/OD site typically consists of a central detonation area or pit, or in
the case of an OB operation, a central burning tray or burning pit. For an OD site, all combustible
materials and loose stones must be cleared within a 61-meter (200-foot) radius of the center of the
site.
d. Engineering controls and/or protective structures for personnel or other measures to
suppress the blast and/or fragment effects may be used to reduce the required separation distance.
Engineering controls will be determined on a site-specific, munition-specific basis. The designs
for engineering controls must be included in the Explosives Safety Submission (ESS) and
submitted to the OE MCX for review and approval. Figures 3-2 and 3-3 provide general examples
of engineering controls that can be constructed where the minimum safe fragmentation distance
requirement cannot be met. Tables 3-2.A and 3-2.B may be used to determine the required
personnel separation distances due to overpressure when using burial as an engineering control.
