Difficulty: MediumSafety Procedures and Environmental Controls

An IT technician is preparing to replace a damaged motherboard inside a desktop computer workstation. To prevent electrostatic discharge (ESD) from damaging the sensitive integrated circuits during installation, the technician equips an ESD wrist strap. Which of the following is the proper connection point for the wrist strap's alligator clip?

  1. An unpainted metal section of the computer chassisAnswer
  2. B
    The ground pin receptacle of an active electrical wall outlet
  3. C
    The outer surface of the anti-static bag storing the replacement motherboard
  4. D
    A painted structural screw located on the exterior of the computer casing

Answer

Connecting the ESD wrist strap alligator clip to an unpainted metal section of the computer chassis ensures proper electrostatic potential equalization.
Attaching the ESD wrist strap clip to an unpainted metal surface of the computer chassis ensures conductive contact, equalizing the electrical potential between the technician's body and the equipment to prevent ESD damage.

Step-by-Step Solution

1
Identify the target component and safety risk.
Recognized that handling internal computer components requires protection against Electrostatic Discharge (ESD).
Static electricity can damage sensitive integrated circuits such as RAM and motherboards even at low voltages undetectable to human touch.
2
Determine the proper grounding mechanism for an ESD wrist strap.
Selected an unpainted metal surface on the equipment chassis.
Clipping to bare metal establishes electrical continuity between the technician and the frame, equalizing charges safely.
