The significant safety concern when installing aerial fiber-optic cable between poles is primarily related to exposure to high-voltage power lines. When installing cables in aerial configurations, workers often operate in close proximity to existing power lines. This introduces risks of electrical hazards, such as electrocution or arcing, especially if proper safety protocols are not followed.

While the buildup of static electricity might be a concern in certain environments, it is not the primary hazard associated with the installation of aerial fiber-optic cables. Static electricity can potentially create issues in terms of shock or interference in sensitive equipment but is generally managed effectively through proper handling and grounding techniques. On the other hand, high-voltage lines present an immediate and serious threat to worker safety, making awareness and adherence to established safety clearance regulations paramount during fiber-optic cable installation.
