Correct Response: B. Safety glasses must be worn during all laboratory activities. In this case, they protect the eyes from splashed molten solder, hot vapors, and from the possibility of being struck by pieces of wire that are projected when trimming excess wire from soldered joints. Leather gloves (A) serve no useful purpose and would actually get in the way when soldering electronic components. Rubber shoes (C) are necessary when working with high voltages, but most printed circuit boards operate at low voltages and should be completely disconnected from any power source while being soldered. An antistatic wrist strap (D) is sometimes required when working on some circuit boards to protect delicate circuit components from electrostatic discharge, but is not necessary in all cases.
