Question 505Electricity & Electronics - QMED

The correct answer is D) use a fuse puller. When changing fuses, the most important safety precaution is to use a fuse puller. A fuse puller is a specialized tool designed to safely remove and install fuses, preventing direct contact with the electrical components. This is crucial because fuses carry high voltage and current, and touching them directly can result in electric shock, arc flash, or other electrical hazards. The other options, while important safety practices in general, are not specifically required for changing fuses. Wearing safety glasses, standing on a rubber mat, or wearing rubber boots are good safety measures, but they do not directly address the specific hazard of handling live electrical components when changing a fuse.
