While at a friend’s house, you are asked to install a new DIMM into a system. Although you’ve done this procedure countless time, you are concerned about ESD prevention. Which of the following could be done to mitigate the possibility of ESD in this case?
Explanation
Answer: B - Frequently touching or keeping a hand on the computer chassis throughout an upgrade is an effective way to mitigate the possibility of ESD while working on a system.
Key Takeaway: ESD is a technician’s number one concern when dealing with exposed hardware or circuitry. Although it is ideal to use antistatic bag and an ESD wrist strap, mat, or apron, touching the computer chassis (the metal portion) grounds the technician to the system, sending any current in the technician’s body harmlessly into the metal surrounding the computer. This way, the technician can be secure that they are not going to damage the internal components of the PC.
