Who makes electrical repairs in the mine?

• A. Certified Electrician
• B. Maintenance Supervisor
• C. Licensed Electrician
• D. Electrical Apprentice Under Supervision

Answer: (A)

Electrical repairs in a mine are safety‑critical and must be performed by someone who has formal certification proving they can work with electrical systems in a mining environment. A certified electrician carries that credential, so they’re the ones authorized to carry out repairs underground or in mine facilities. A maintenance supervisor handles oversight and general maintenance tasks but isn’t the person designated to perform electrical repairs. A licensed electrician might exist in some contexts, but this item specifies certification as the required credential. An electrical apprentice under supervision can assist with tasks but isn’t qualified to perform independent repairs on electrical equipment.
