Question 8-50F4

Wearing gloves and goggles is essential when handling a CRT. CRTs are vacuum tubes made of glass, and if they are accidentally broken or implode due to stress or mishandling, glass shards can fly at high speed. Goggles provide critical eye protection from these shards, while gloves help prevent cuts from sharp edges and offer some general hand protection. Option A, discharging the first anode, is not the primary electrical safety concern; the *final* (second) anode and its associated capacitors hold the most significant, dangerous residual charge and require proper discharge with an insulated tool. Option B, testing the second anode with a fingertip, is extremely dangerous and could result in severe, potentially lethal electrical shock from the retained high voltage. Option D, setting the CRT on a hard surface, risks breaking or imploding the fragile glass envelope, which is also very hazardous. Therefore, wearing appropriate safety gear (C) directly addresses the immediate physical dangers of handling a CRT.
