What is an avoidance zone in the context of power lines?

• A. That area above and below power lines that is outside the prohibited zone. Crane operations in this area should be avoided.
• B. The area around the crane's operator cab
• C. The area behind the operator
• D. The area under the load path

Answer: (A)

An avoidance zone is the space around overhead power lines that must be kept clear during crane operations to prevent contact or electrical arcing. It covers the region both above and below the lines where the crane, its booms, hooks, and loads must not move. The safety reason is that electricity can arc across gaps and energize anything within a certain distance, which can cause severe shock, burns, or equipment damage even without a direct touch. To stay safe, operations should either de-energize and isolate the lines or keep the crane and load well outside this boundary, often with a spotter and a defined lifting plan. The other areas mentioned—around the operator cab, behind the operator, or under the load path—do not address this external electrical hazard and aren’t the defined avoidance zone for power lines.
