According to safety standards, what is the minimum distance of any ladders supporting point from an overhead line?

The minimum distance of any ladder's supporting point from an overhead line is set at 10 feet due to safety standards established to prevent electrical hazards. This distance is crucial because it helps ensure that workers are not exposed to the risk of electrical shock or electrocution from overhead power lines while using ladders for installation work. Maintaining a buffer zone around overhead lines minimizes the likelihood of accidental contact, especially when extending or lowering ladders, which can occur due to wind or unexpected movements.

The regulations emphasize this safety margin, as equipment can accidentally come into close proximity to high-voltage lines, leading to potentially dangerous situations. Adhering to this guideline is a fundamental part of ensuring a safe working environment for technicians and installers.
