Grounding Methods
The method for grounding must include a wrist strap or a foot strap at a grounded
workstation. When seated, wear a wrist strap connected to a grounded system. When
standing, use footstraps and a grounded floor mat.

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