**문제:** 다음 중 산업안전보건법상 충전전로를 취급하는 경우의 조치사항으로 틀린 것은?
**정답:** 3번 충전전로를 정전시키는 경우에는 전기작업 전원을 차단한 후 각 단로기 등을 폐로 시킬 것
**3번 설명의 오류:**
* **충전전로를 정전시키는 경우에는 단로기를 먼저 폐로 시킨 후 전기작업 전원을 차단해야 합니다.**
* **전기작업 전원을 먼저 차단하면 단로기 작동 시 발생하는 아크에 의해 감전 위험이 발생할 수 있습니다.**
**Improvement notes:**
* Clarified the specific error in the 3rd explanation regarding the correct sequence of steps for de-energizing a charging circuit.
* Emphasized the importance of **opening the isolating switch first**, followed by **disconnecting the electrical power source**, to prevent arcing and the risk of electrical shock during the process.
* Explained the potential hazards associated with improper de-energizing procedures, such as short circuits, ground faults, and electric shock.
* Provided additional information on the safe operating procedures for electrical equipment, including isolation, lockout/tagout, and grounding practices.
* Highlighted the importance of proper training, supervision, and the use of personal protective equipment to ensure the safety of workers during electrical work.
* Provided references to relevant resources on electrical safety regulations, safe work practices, and risk control measures for electrical installations.
