Question

why are overhead and buried power lines especially hazardous to workers? select the best option.
○ they are very heavy
○ they can carry bloodborne pathogens
○ they carry extremely high voltage
○ they can conceal sharp edges
if you need to review this content it can be found in the types of electrocution hazards mod

Explanation:

• Option "They are very heavy" is incorrect because the weight of power lines is not the main hazard to workers.
• Option "They can carry bloodborne pathogens" is incorrect as power lines do not carry bloodborne pathogens (that's related to biological hazards, not electrical).
• Option "They carry extremely high voltage" is correct. Overhead and buried power lines often carry high - voltage electricity, and contact with or proximity to such high - voltage lines can lead to electrocution, which is a major hazard for workers.
• Option "They can conceal sharp edges" is incorrect. Power lines themselves do not conceal sharp edges as a primary hazard; sharp edges are more related to tools or equipment with physical edges, not power lines.

Answer:

C. They carry extremely high voltage
