Can ESD-protective lab coats be used without ESD heel straps in an ESD-protected area? If ESD heel straps or static control shoes are not worn and there is no static control floor, then the person is not grounded. Both the proper footwear and the proper floor are needed to complete the connection from garment to body to ground. For ESD applications where the required strap resistance is 1 megohm, the tester uses a lower limit of 750 kilohms and upper limits of either 1.25 megohms (for the ESD heel strap only) or 10 megohms (for the ESD heel strap and the wearer). They should be used in conjunction with Anti-Static matting floor as a direct replacement for the ESD heel strap. Wrist straps can be tested with a touch of the contact plate, and ESD heel straps are easily tested using the metal footplate. The purpose of the wrist strap is to drain off the operator's static charge. A wrist strap or ESD cuff is kept in constant contact with bare skin and has a cable for attaching it to the ESD ground. The wrist strap cord has a current- limiting resistor for personnel safety. ESD heel strap must be tested frequently to assure that they are undamaged and operating correctly. When a wrist strap is impractical, there are special ESD heel straps or shoes that can be used. These items are effective only when used in conjunction with a dissipative floor.
