connectors or test equipment.
4.7 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 megaohm
±10% resistance in the ground cords. To provide proper ground,
wear a strap snug against the skin at all times. 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 includes:
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
Electrostatic voltage levels and protective materials
