What is a potential hazard of working too close to power lines?

The potential hazard of working too close to power lines is the risk of electrocution. This danger arises from the fact that power lines carry high voltages, and coming into close proximity can result in an electrical arc or direct contact with the line. Such an occurrence can lead to severe injuries or fatalities due to electric shock.

Understanding the risks associated with power lines is crucial for safety in construction and other outdoor work environments. Training and protocols are often established to maintain safe distances and to employ proper equipment and procedures whenever work needs to be conducted near these hazards. The other choices do not pertain to the dangers of working near power lines, as they suggest benefits or features that are unrelated to safety concerns. Improved visibility, enhanced signal reception, and increased load-carrying capacity are not valid considerations when evaluating the hazards of proximity to high-voltage electrical lines.
