Electro-Static Discharge (ESD) tools are used to safely discharge static electricity and protect electronic components from electrostatic discharge events. Common ESD tools include grounding cords, antistatic tools, antistatic gloves, ESD rubber matting, and antistatic clothing. These tools work to dissipate static electricity and prevent its buildup by providing conductive paths to ground potential. Proper use of ESD tools like connecting antistatic mats and wrist straps to grounding points helps protect sensitive electronic equipment from damage due to static electricity.
