What is the minimum safe distance for cranes and derricks working near high tension lines?

The correct answer is based on established safety protocols for cranes and derricks operating in proximity to high tension power lines. A minimum safe distance of 20 feet is required to prevent accidental contact with power lines, which can pose serious risks of electrocution and other hazards to workers. This distance allows for a buffer zone that minimizes the chances of either the equipment itself or any load being lifted coming into close contact with live electrical lines.

Safety regulations recognize that high voltage lines can have significant electrical arcs, which can extend beyond the visual line of sight, making 20 feet a prudent minimum to mitigate hazards. Adhering to this guideline is essential for maintaining a safe working environment, as it protects both the operators and the safety of surrounding personnel. This regulation underscores the importance of vigilance and awareness in construction sites that may operate near electrical infrastructure.
