Removal and Replacement Preliminaries ■ 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 Maintenance and Service Guide 5-7
