1.5.8 Army Adopted Configuration
. In general, a protective workstation must occupy a 10-foot
(3-meter) square area and be cordoned off with yellow lines or other means of segregation. The
area should be posted with signs identifying it as a static-free work area. This protective station
may be used for packaging or by maintenance personnel for repairing sensitive devices, but not
when applying power to the instrument for testing.
1.5.9 Precautions within 20-foot (6-meter) Distance
. For purposes of initially established
work-sites, the major controlled area shall be considered as that area within a 20-foot (6-meter)
radius of the bench(es). Within this controlled area, the following should be excluded:
a. Materials handling trucks, carts, and equipment.
b. Conveyor drive mechanisms and moving belts.
c. Sandblast and air-cleaning equipment.
d. Paint spray booths and ventilating equipment.
e. Storage of bulk common plastic materials such as large rolls of cushion wrapping
material, loose fills, slab cushioning, or fastpacks.
1.5.10 Precautions within 50-foot (15-meter) Distance
. A special hazard exists in areas
where stretch and shrink wrapping operations are performed. This is also true where skin
packaging, foam-in-place. and plastic bagging are conducted. These types of functions must be
kept at least 50 feet (15 meters) away from static-protected worksites.
