Before you open a desktop computer, you should always disconnect the power cord. While you are working inside the powered-off system, which piece of personal safety equipment should you wear to prevent static electricity from damaging sensitive components?
Safety goggles
Steel-toe boots
ESD wrist strap
Work gloves
An electrostatic discharge (ESD) wrist strap continuously equalizes electrical potential between your body and the computer chassis. By safely channeling any built-up charge to ground, the strap prevents sudden discharges that could destroy chips, memory, or other delicate circuits. Safety goggles, work gloves, and steel-toe boots may protect you from physical hazards, but they do nothing to dissipate static electricity, so they are not the correct choice in this scenario.
