Equipment guidelines

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 must be worn in contact with the skin.

The following grounding equipment is recommended to prevent electrostatic damage:

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

The following table lists the shielding protection provided by antistatic bags and floor mats.
