of electronic

small enough,
put it into one of

Whichever way you go, finish the job with a fast pack. Two useful ESD fast packs
are NSN 8115-01-019-4084 for 12x18x3-

These common items have a high static charge: candy wrappers, folders, paper,
styrofoam cups, cigarette packs, plastic and masking tape, plastics, vinyl, heat guns
with blowers and common packing material. Keep them away from the work site. If
you must have technical manuals and paperwork at the workstation, store them in
antistatic bags.
When you package a circuit card in the protective plastic wrap, put a rubber band
around it—
never
use tape to fasten it. The tape holds static electricity.
Things like magnets, radios, tape players and telephones can create an electro-
magnetic field. Keep them clear of the workstation.
If as part of your job, you must package an item in stretch-wrap or shrink-wrap,
do it away from your workstation. Packaging an item with these wraps generates
static electricity.
High Charge
Training
Anyone handling ESDS items
should be trained in ESDS precau-
tionary procedures. Untrained per-
sonnel should
never
handle ESDS
items when the items are outside
the ESDS protective packaging.
PS 587
Make sure your grounding cords are
firmly attached to bare metal, not paint.
Wear your wrist strap on your skin, not
over your sleeve, or it won't work.
Replace grounding cords if they're
badly worn or cut.
Grounding
Connect table and floor
mat grounding cords directly
to shop ground. Ground each
workstation
individually.
Never connect workstations
in series to ground them. If
connected when one goes out,
they all become ungrounded.
Resistance Checks
Follow the manufacturer's instructions for measuring the resistance of your work-
station components. That's the only way to be sure your workstation's doing its job
of carrying static charges to ground.

A few precautions
and some regular
PM around your
workstation will
keep static
electricity under
control.

Clean Means Safe
Dirt and dust on the table and
floor mats act as insulators, making
it harder for the mats to carry electri-
cal charges to ground. Clean the
mats with a soft cloth or brush them
with a whisk broom.
Use only brushes made with natu-
ral bristles, such as horse hair.
Brushes made with nylon or other
synthetic bristles will generate static
electricity.
Never wax or polish the table or floor mats.
That leaves a residue that insulates the mats.
