Explanation
An anti-static wrist grounding strap is the correct personal protective equipment to prevent electrostatic discharge (ESD) when handling internal computer components.
Common mistakes.
- A. Safety goggles protect the eyes from physical hazards such as debris or chemicals but provide no protection against electrostatic discharge.
- C. Safety shoes (steel-toed boots) protect feet from physical impact or falling objects and do not mitigate static electricity risk.
- D. Canvas gloves are not anti-static and can actually generate static electricity through friction, potentially increasing ESD risk.
