APPENDIX C
OB/OD CHECKLIST
SITE SELECTION (OB/OD AREAS)
PARAGRAPH
Determine the direction of the prevailing winds and ensure that they are not directed
3-1.c
toward the Explosive Storage Area or temporary holding magazine.
Dry grass, leaves, and other extraneous combustibles must be removed from a
3-1.c
61-meter (200-foot) radius of the OD site.
3-1.f
Ensure no public utility lines are located in or near the OB/OD area. If utilities
cannot be avoided, contact the owners of the utility to develop the necessary
protective measures.
Take advantage of the topography (e.g., slopes, hills, etc.) when locating OB/OD
3-2
area to ensure public areas are shielded from OB/OD operations, whenever possible.
If personnel protective structures will be built, all plans must be design reviewed and
3-3.e
approved by the OE MCX.
Ensure the temporary Explosives Storage Area or donor explosives will be located
3-3.f
outside the exclusion zone.
Ensure radio frequency energy or stray electrical current is not present in the area.
3-3.g
Establish roadblocks at all entrances and exits to the OB/OD area at the
3-3.h
fragmentation zone distance.
Ensure that a sufficient distance has been allowed between the OB/OD area and all
3-3.a
public places. Calculate the anticipated overpressure hazards using the equation
D=328W1/3, where W is the NEW in pounds of ordnance to be destroyed and D is
the distance in feet that must be maintained from the OB/OD area place to reduce
the overpressure hazards.
Ensure that personnel have protection from fragmentation hazards generated during
3-3.a,
OB/OD operations.
Table 3-1
Determine noise requirements for the OB/OD operation.

SITE SELECTION (OB - SPECIFIC REQUIREMENTS)
PARAGRAPH
Ensure an area of 92 meters by 92 meters (300 feet by 300 feet) is completely
3-5.a
cleared in each direction from the OB area.
Ensure that dry grass, brush, debris, and leaves are cleared for a distance of 153
3-5.a
meters (500 feet) in all directions.
Ensure that the distance between multiple burning sites will be sufficient to prevent a
3-5.e
burning ember landing on an adjacent site (a minimum of 46 meters (150 feet)
distance is required).
