4.1.5 Grounding Workstations
To prevent static damage at the workstation, use the following
precautions:
o Cover the workstation with approved static-dissipative material. Provide
a wrist strap connected to the work surface and properly grounded tools
and equipment.
o Use static-dissipative mats, foot straps, or air ionizers to give added
protection.
o Handle electrostatic sensitive components, parts, and assemblies by the
case or PCM laminate. Handle them only at static-free workstations.
o Avoid contact with pins, leads, or circuitry.
o Turn off power and input signals before inserting and removing
connectors or test equipment.
o Use fixtures made of static-safe materials when fixtures must directly
contact dissipative surfaces.
o Keep work area free of nonconductive materials such as ordinary plastic
assembly aids and Styrofoam.
o Use field service tools, such as cutters, screwdrivers, and vacuums,
that are conductive.
o Use a portable field service kit with a static-dissipative vinyl pouch
that unfolds to become a work mat. Also, use a wrist strap and a ground
cord for the work surface.

4.1.6 Grounding Equipment
Use the following equipment to prevent static electricity damage to
equipment:
Wrist Straps are flexible straps with a minimum of one megohm +/- 10%
resistance in the ground cords. To provide proper ground, a strap must be
worn snug against the skin.
connectors, connect a wrist strap with alligator clips.
Heelstraps/Toestraps/Bootstraps can be used at standing workstations and
are compatible with most types of shoes or boots. On conductive floors or
dissipative floor mats, use them on both feet with a minimum of one-megohm
resistance between the operator and ground. To be effective, the
