According to OSHA 1926.1408, what is the minimum clearance required between cranes and power lines rated 50kv or below?

The minimum clearance required between cranes and power lines rated at 50 kV or below is specified in OSHA regulations to ensure the safety of workers and equipment. The correct answer reflects that a distance of 10 feet is necessary when encroachment precautions are in place. This precautionary distance is in recognition of the potential hazards posed by electrical lines, which can create dangerous situations if equipment comes too close to them or if the lines sag due to weight or other factors.

Maintaining a distance of 10 feet helps to minimize the risk of electrical shock or arcing, especially since cranes may accidentally come into contact with power lines during operation. Encroachment precautions might include specialized equipment, training, or procedures designed to provide additional safety when working in proximity to these hazards. This regulation is part of OSHA's broader framework to promote safety in construction environments, ensuring that both workers and equipment can operate safely around electrical infrastructure.
