Figure 4 ESD protection
Both types, when used together, provide a significant level of ESD
protection. Of the two, only the table-mat and wrist-strap combination
provides adequate ESD protection when used alone. To ensure user safety,
the static-safe accessories must provide at least 1 MW of isolation from
ground.
These techniques for a static-safe work station should not be used when
working on circuitry with a voltage potential greater than 500 volts.
