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 exible 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 oor 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 oors

or dissipative oor mats, use foot straps on both feet with a minimum of one megohm resistance between

the operator and ground. To be

eective, 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 computerop workstations with ground cords of one megohm resistance

● Static-dissipative tables or oor 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 oor mats.

Material Use Voltage protection level

Antistatic plastics Bags 1,500 V

Carbon-loaded plastic Floor mats 7,500 V

Metallized laminate Floor mats 5,000 V
