What should be used to ground personnel working with ESD-sensitive devices?

• A. Non-static gloves
• B. Wrist straps
• C. Grounded footwear
• D. Conductive floors

Answer: (B)

Wrist straps are essential for grounding personnel who work with ESD-sensitive devices because they create a direct electrical connection between the individual and ground. This connection helps to safely dissipate any static charge that might accumulate on a person's body, thereby preventing the transfer of that charge to sensitive electronic components, which could cause damage or malfunction. Using a wrist strap ensures that a person's potential remains equal to that of the grounded surface, thus minimizing the risk of static discharge when handling sensitive equipment. Wrist straps are designed to be adjustable and comfortable, allowing for continuous grounding during work tasks, which is paramount in environments that handle ESD-sensitive devices. While non-static gloves, grounded footwear, and conductive floors can all contribute to an ESD-safe environment, they do not provide the direct personal grounding that wrist straps offer. The effectiveness of those alternatives varies based on the workplace and usage, making wrist straps the most reliable choice for immediate grounding of personnel.
