Grounding Equipment and Methods

Grounding equipment must include either a wrist strap or a foot strap at a grounded
workstation.
When seated, wear a wrist strap connected to a grounded system. 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. On grounded
mats with banana-plug connectors, connect a wrist strap with alligator clips.
When standing, use foot straps and a grounded floor mat. Foot straps (heel, toe, or
boot straps) 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 conductive strips must be worn in contact with the skin.
Other grounding equipment recommended for use in preventing electrostatic damage
include:
Antistatic tape
Antistatic smocks, aprons, or sleeve protectors
Conductive bins and other assembly or soldering aids
Non-conductive foam
Conductive tabletop workstations with ground cord of one-megohm resistance
Static-dissipative table or floor mats with hard tie to ground
Field service kits
Static awareness labels
Material-handling packages
Non-conductive plastic bags, tubes, or boxes
Metal tote boxes
