A technician is replacing the processor in a desktop computer. Prior to opening the computer, the technician wants to ensure the internal components are protected. Which of the following safety…

Utilizing an ESD (Electrostatic Discharge) strap grounds the technician, preventing static electricity from building up on their body and discharging into sensitive computer components, which can cause permanent damage. This is a critical safety measure when handling internal PC parts.

Disconnecting the computer from the power source completely removes electrical current, preventing accidental short circuits, electrical shock, and damage to components during installation or maintenance. This is a fundamental safety practice before opening a computer case.

Placing the PSU (Power Supply Unit) in an antistatic bag protects the PSU itself during storage or transport, but it is not a direct safety procedure for working inside the PC to protect other internal components.

Ensuring proper ventilation is an operational consideration for cooling components during use, not a safety procedure for protecting components while working inside the computer.

Removing dust from ventilation fans is a maintenance task to improve cooling, not a safety procedure for protecting components during service.

Ensuring equipment is grounded is typically for the safety of the user and the overall electrical system, but an ESD strap specifically addresses the technician's potential for static discharge to internal components, while disconnecting power removes the primary electrical hazard.
