b. When non-essential personnel must enter the PSD area, the following must be
accomplished:
(1) The individual must receive a safety briefing before entering the OB/OD PSD area.
(2) All OB/OD operations must cease.
(3) The individual(s) must be escorted by a UXO-qualified individual at all times while in
the OB/OD PSD area.
5-4.
Hours of Operation. OB/OD operations are prohibited between sunset and dawn.
5-5. Weather Restrictions. OB/OD operations will not be conducted in inclement weather.
Weather conditions affect both the location and timing of OB/OD operations. The optimum wind
speed for an OB/OD operation is 4 to 15 mph, because winds at these speeds tend not to change
direction and, as a result, dissipate smoke relatively rapidly. OB/OD operations are never
conducted during sand, snow, or electrical storms strong enough to produce static electricity,
which might cause premature detonation.
5-6.
OB Specific Requirements.
a. Open burning of explosives and smokeless powder or chemical decomposition of
explosives will not be accomplished without prior approval of the CO.
b. Anticipate a high order detonation when burning pyrotechnics or incendiary-loaded
UXO. Safety measures for personnel and property must be based upon this possibility.
c. Disposal by open burning will not be undertaken when wind velocity exceeds 15 mph.
5-7.
Maintenance of Grounds.
a. For OD operations, all dry grass, leaves, and other flammable materials within a radius
of 61 meters (200 feet) from the point of destruction will be removed.
b. The OB/OD area will be kept clean and orderly at all times.
c. Explosive items, hazardous materials, inert OE scrap, and wood, paper, and
combustible packaging materials will not be mixed. Each of these categories will be carefully
controlled and placed in separate, approved, and properly marked containers. The containers will
be placed outside of the OB/OD area, except for containers required at the work location during
operations. Working location containers will be emptied as needed but at least once during each
8-hour shift.
d. The above listed items will be removed to proper disposal areas at frequent intervals
and prior to leaving at the end of the duty day or shift. When isolated collection points are used,
time and quantity limits, which comply with environmental regulations, will be set up to ensure
