3.1.4 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, foot straps, or air ionizers to give added protection.

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.
