Explanation
When an ESD (Electrostatic Discharge) strap is unavailable, the correct practice is to use self-grounding techniques-periodically touching a known grounded metal object (such as an unpainted metal part of the laptop chassis while it is unplugged) to discharge built-up static electricity before handling components. Returning to the shop (A) may not be practical in a field scenario. Using ESD bags as mitts (B) is not a standard or reliable practice. Improvising with copper wire (D) is dangerous-an improperly constructed grounding path could damage components or create a shock hazard. Self-grounding is the accepted field workaround.
