pouring, weighing, charging, sifting, drying, pressing, casting, and crimping.
6 . 5 . 3 Personnel handling detonators, primers, delay elements, lead-ins,
boosters, and related parts that affect functioning, should, insofar as practi-
cable, avoid using bare fingers or improper equipment to prevent damage,
corrosion, or deterioration from perspiration or other contaminating deposits.
6.5.4 The exposure of explosive materials and related parts should be so
controlled as to minimize the absorption of moisture from the atmosphere or
other sources during loading and handling operations.
6.5.5 All explosives and completely or partially loaded items should be
stored in suitable storage magazines located in accordance with the American
Table of Distances (ATD) or other applicable safety standards; and, while in pro-
cess, in safety lockers and chests if in loading rooms, or in adequate ready or
service magazines located in accordance with intra-plant distances when outside
of loading rooms. For Navy explosives loading plants, the provisions of the
Armed Services Explosives Safety Board covering quantity-distance relations for
explosives shall apply.
6.5.6 Proper care should be exercised at all times to protect personnel
from accidents, fires, or explosions, and to limit damage to equipment and load-
ing areas. In this connection, the following precautionary measures should be
observed.
6.5.6.1 Employ properly proportioned and properly located protective
barricades, screens, or shields at all required points.
6.5.6.2 Keep only minimum limited quantities of explosives and completed
or partially loaded parts present at each stage of operation.
6.5.6.3 Keep explosives and explosive parts in approved, covered recep-
tacles with covers in place when material is not being taken out of or put into
the receptacles. Where necessary, receptacles should be conductive to ground
e l e c t r o s t a t i c charges.
6.5.6.4 Protect operations from electrostatic charges by effectively
grounding all machinery, equipment, and fixtures; and, where necessary, em-
ploy suitable grounded conductive coverings for floors, work benches and tables,
and workers' conductive shoes. Workers' clothing of a type to minimize the
accumulation of static charges should be employed. Fabrics such as silk and
nylon, which promote static generations should be avoided. Additional grounding
devices such as grounded bracelets for workers should be employed where op-
erations are conducted with items that are usually sensitive to initiation by static
e l e c t r i c i t y . Such items include initiating explosives, tracer mixtures, and low-
energy-type electric primers, detonators, and squibs. The latter types of items
