Which of the following is a common hazard associated with telecommunications tower work?

High-altitude falls are indeed a significant hazard associated with telecommunications tower work. Technicians often perform their duties at considerable heights, which can lead to dangerous situations if proper fall protection measures are not implemented. Working from elevations requires adherence to safety protocols, including using harnesses, lanyards, and guardrails to mitigate the risk of a fall. The nature of the work, involving the installation, maintenance, and inspection of antennas, lines, and equipment on tall structures, inherently increases the potential for falls, making this hazard one of the most critical concerns in the field.

While ground-level vehicle traffic, confined space entry, and exposed electrical wiring can pose risks in various job environments, they do not specifically reflect the primary dangers encountered when working atop telecommunications towers. High-altitude falls are unique to the vertical nature of tower work, distinguishing it from other jobs that may involve similar hazards but at different elevations or contexts.
