What is the minimum feet separation between any part of a crane and power lines allowed?

1. 5 feet

2. 10 feet

3. 15 feet

4. 20 feet

The correct answer is: 10 feet

The minimum separation distance of 10 feet between any part of a crane and power lines is established to ensure the safety of workers and the prevention of electrical hazards. When cranes operate near power lines, there is a significant risk of accidental contact with the lines, which can lead to serious injuries or fatalities due to electric shock. The 10-foot guideline is rooted in safety standards and regulations that aim to protect both the equipment operators and those working on-site. The rationale for this specific distance is that it provides a buffer zone that allows for both static and dynamic movements of the crane. This takes into account the potential for the crane's boom to swing or for load lines to have some degree of movement. By maintaining a 10-foot separation, it allows for a safety margin that can prevent unintended contact, ensuring that operators have a clear understanding of their surroundings and reducing the likelihood of incidents. While other distances may be considered in different guidelines or under specific conditions, the 10-foot rule is a widely accepted standard that reflects a consensus on safety practices in construction and industrial settings involving cranes.
