Should I Wear ESD Socks?

The Need For ESD Socks

The combination of ESD flooring and footwear can be an effective way to ground personnel to control electrostatic discharges when using a wrist strap is not practical. For this system to be effective, the ESD flooring and footwear must have a low enough resistance to allow the voltage from the operator to flow to ground. There also must be a good contact between the person and the ESD footwear.

While ESD shoes may be made with conductive materials, they require a layer of perspiration in the sock to provide a path-to-ground. This is a concern because there are many variables between people. Per ESD Handbook TR20.20 section 5.3.3.5 Common Testing Problems “Occasionally, footwear may indicate a high resistance… [A contributor being] heavy or insulative socks, or the absence of a sweat layer due to differences in temperature between the inner surfaces of the shoes and the wearer’s feet.”

How much time is wasted waiting for shoes to pass a test?
Or worse, how many sensitive items does a person come into contact with before their ESD shoes are truly acting as a path-to-ground?

Eliminate these variables and ensure a consistent path-to-ground with conductive ESD socks¬†from Transforming Technologies. ESD socks are made with conductive yarn which provides a reliable electrical path from the start and rely less on the wearer’s skin resistance for repeatable performance regardless of the environment.
