What device drains static charge from the person wearing it?

• A. Static dissipative work surface
• B. Personnel wrist strap
• C. Grounding strap
• D. Wrist strap tester

Answer: (B)

The device designed to drain static charge from the person wearing it is the personnel wrist strap. This tool is specifically engineered to create a pathway for static electricity to safely discharge to the ground, preventing the buildup of static charge on a person’s body. When worn properly, it ensures that any accumulated static charge is continuously dissipated, mitigating the risk of Electrostatic Discharge (ESD) events that could damage sensitive electronic components. The functioning of a personnel wrist strap hinges on its connection to a ground point, often through a cord attached to equipment or a ground socket. This direct connection effectively neutralizes static by allowing excess electrons to flow safely away from the body and into a grounded source, ensuring the wearer remains at the same electrical potential as the ground. Static dissipative work surfaces, grounding straps, and wrist strap testers play important roles in ESD control, but they do not serve the individual purpose of directly discharging static charge from a person’s body in the way that a personnel wrist strap does. Instead, they contribute to the overall ESD control environment and help maintain safe working conditions for sensitive electronic devices.
