A technician is repairing a computer. Which of the following should the technician do to protect the computer from accidental voltage spikes?

Question

Options

• APractice electrical fire safety.
• BClean tools properly before use.
• CRemove any jewelry.
• DConnect a proper ESD strap.

• A
  3% (1)
• B
  5% (2)
• C
  3% (1)
• D
  90% (36)

Explanation

Connecting an ESD (Electrostatic Discharge) strap (D) grounds the technician to the same electrical potential as the computer chassis, preventing the buildup and sudden discharge of static electricity. ESD events - even those too small for a human to feel - can cause immediate or latent damage to sensitive electronic components through voltage spikes. Practicing fire safety (A) addresses a different hazard entirely. Cleaning tools (B) prevents physical contamination but not electrical damage. Removing jewelry (C) is a good safety practice to avoid short circuits or snagging, but it does not protect against ESD or voltage spikes the way a grounding strap does.
