CONSOLIDATED SHOTS
D3.0 Safe Personnel Separation Distance
D3.0.1 This document covers procedures for intentional detonations only.
D3.0.2 In accordance with DoD 6055.9-STD Chapter 5 paragraph E.4.a(2), the safe separation
distance for all personnel will be the greater of the overpressure distance or the appropriate
fragment range as determined by the maximum fragment range or the mitigated fragment range.
D3.1
Overpressure Distance
In accordance with DoD 6055.9-STD Chapter 5 paragraph E.4.a(2), the allowable overpressure
distance will be determined as the scaled distance, K328, based on the total net explosive weight
(NEW) of all munitions plus the initiating explosives.
D3.2 Fragment Criteria
D3.2.1 Maximum Fragment Range
The maximum fragmentation characteristics shall be computed in accordance with HNC-ED-CS-
S-98-1. The maximum fragment range shall be computed using these fragmentation
characteristics with a trajectory analysis such as the computer software TRAJ. The maximum
fragment range shall be the maximum fragmentation distance computed for the most probable
munition (MPM) for an OE area at a site, and this shall be the maximum fragment range for a
consolidated shot.
D3.2.2 Fragment Mitigation
Fragment mitigation may be provided by an appropriate Department of Defense Explosives Safety
Board (DDESB) approved engineering control. Typical engineering controls for intentional
detonation include tamping and sandbags. The design of such an engineering control shall be
based on the maximum fragmentation characteristics of the MPM. The NEW used for the design
of the engineering control shall be the total NEW of all munitions plus the initiating explosives.
Engineering controls not already approved by DDESB may be submitted (along with appropriate
technical data) as part of a site specific explosive safety submission for use at that site.
Engineering controls will not be put into use until approved by DDESB and specific applications
verified by the appropriate agency; for example, the OE-CX verifies applications for U.S. Army
Corps of Engineers.
D4.0 Initiation
The consolidated shot shall be initiated in such a manner that detonation of all munitions is
simultaneous.
