Which statement is true about anti-static wrist straps?

• A. False
• B. They should be worn during maintenance.
• C. They are optional in most cases.
• D. They must be connected to a power source.

Answer: (B)

Static electricity can damage sensitive electronic components, so you need a controlled path to ground when handling equipment. An anti-static wrist strap provides that path, draining away any buildup as you work and keeping your body at earth potential. Because of that, wearing it during maintenance is essential to protect both you and the hardware from electrostatic discharge. The strap is connected to ground, not to a live power source, usually via a cord to a grounded mat or the equipment chassis. In most maintenance situations, using the strap is standard practice to minimize ESD risk, not something optional.
