전원이 공급되는 장치에서 작업할 때 IT 기술자는 노출된 배선으로 인한 감전 위험을 의심합니다. 가장 안전한 첫 번째 조치는 무엇입니까?
정답: B
Correct Answer. B. Immediately turn off the power to the device before proceeding further Turning off the power immediately is the safest approach when dealing with exposed wiring, as it eliminates the risk of electrical shock, allowing for safe subsequent handling of the wiring issue. Option A is incorrect because continuing to work near exposed wires without addressing the risk is unsafe. Option C is incorrect as covering the wires with electrical tape does not address the potential hazard of the device being powered on. Option D is incorrect because testing exposed wires while the device is powered could lead to electrical shock if the wires are live.
