What is the minimum distance that all aerial devices should remain from overhead wires?

The correct choice indicates that aerial devices must maintain a minimum distance of 10 feet from overhead wires. This distance is crucial for ensuring the safety of both the operator and the crew while preventing potential electrical hazards.

Electric wires can carry high voltages, and coming too close to them can result in serious accidents, including electrocution. The 10-foot clearance is a standard safety measure that allows for a sufficient buffer zone, taking into account that the aerial device may inadvertently move closer during operations or in windy conditions. This regulation is adhered to by various safety organizations to minimize risk and ensure safe operation in proximity to power lines. Understanding and applying this safety standard is integral for all personnel involved in operating aerial devices.
