What are potential hazards when working near overhead power lines?

When working near overhead power lines, the most significant hazards include electrocution, burns, and falls. Electrocution is the most serious risk, as power lines carry high voltage electricity that can cause severe injury or death if contact is made. Burns can occur not only from direct contact but also from electrical arcs, which can jump from a power line to a person or object in the vicinity. Falls can happen due to the nature of construction and lineman work, particularly when working at heights and navigating around power lines, which adds an extra layer of risk.

The other options present plausible concerns in various scenarios but do not directly capture the most immediate dangers associated with overhead power lines. For example, while fire outbreaks or equipment failure can happen in certain contexts, they do not address the direct risks faced during lineman tasks related to overhead power lines. Understanding and recognizing the primary hazards of electrocution, burns, and falls is crucial for safety in this line of work.
