Who is allowed to work on exposed energized lines or parts of equipment?

• A. Unqualified workers
• B. Supervisors only
• C. Qualified workers
• D. Any employee with training

Answer: (C)

Working on exposed energized lines or parts is restricted to a qualified worker. This means someone who has received specific training and demonstrated the ability to work safely around energized electrical equipment. Being qualified goes beyond general training: it includes understanding the hazards of electricity, recognizing energized parts, and knowing how to select and use the correct protective equipment, tools, and procedures (such as testing, grounding, and lockout/tagout) before beginning work. The risk of shock, arc flash, and burns is high, so only those who are authorized and have proven competencies to manage these hazards should perform such tasks. Supervisors can oversee or assist, but if they are not qualified to perform the work on energized parts, they should not do it themselves. An employee with training alone may not be considered qualified until they have the required practical skills and authorization.
