What does the prohibited zone refer to in crane operation?

The concept of a prohibited zone in crane operation is critical for maintaining safety on a job site, particularly regarding proximity to power lines. The prohibited zone refers specifically to the area near a power line where no part of the crane, including its load, is allowed to enter. This zone is established to prevent accidental contact with live electrical wires, which can pose serious safety risks, including electrocution and power outages.

In crane operations, it is essential for operators and personnel to be aware of and respect these boundaries to ensure the safety of everyone involved and to avoid damaging equipment or infrastructure. Proper safety protocols must be followed, including maintaining a safe distance from power lines and understanding the specific dimensions of the prohibited zone related to the type of crane being used.

The other options do not correctly define the prohibited zone, as they refer to different aspects of crane operation and job site management. The freely operating area, maintenance zones, and storage areas do not take into account the critical safety issues associated with proximity to power lines.
