4.7Grounding 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, wear a strap snugly against the skin at all times. On grounded mats with banana-plug connectors, use alligator clips to connect a wrist strap.

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 foot straps 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 includes:

Antistatic tape

Antistatic smocks, aprons, and sleeve protectors

Conductive bins and other assembly or soldering aids

Nonconductive foam

Conductive tabletop workstations with ground cords of one megohm resistance

Static-dissipative tables or floor mats with hard ties to the ground

Field service kits

Static awareness labels

Material-handling packages

Nonconductive plastic bags, tubes, or boxes

Metal tote boxes

Electrostatic voltage levels and protective materials
