What is the minimum distance an aerial apparatus driver/operator should maintain from overhead lines?

Answer: B — 10 feet (3m)

The minimum distance an aerial apparatus driver/operator should maintain from overhead lines is 10 feet (3m). This distance is crucial for safety to prevent electrical hazards, as contact with overhead power lines can be extremely dangerous and potentially fatal. Maintaining a distance of 10 feet allows for a safe operating margin that protects both the driver/operator and the equipment from accidental contact with high-voltage lines. This standard is informed by regulations and best practices established by safety organizations, which emphasize that even without direct contact, close proximity to live electrical lines can pose risks due to arcing or electrical fields that may be present. Therefore, the 10-foot distance is a key safety measure to ensure that aerial operations can proceed without jeopardizing personnel or equipment.
