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 module of the avoiding electrocution hazards (construction) topic

Explanation:

• "They are very heavy" is incorrect as the hazard from power lines is not related to their weight.
• "They can carry bloodborne pathogens" is wrong because power lines don't carry pathogens.
• "They carry extremely high voltage" is correct. Overhead and buried power lines transmit electricity at high voltages, and contact or proximity can lead to electrocution, which is a severe hazard for workers.
• "They can conceal sharp edges" is incorrect as power lines don't have sharp edges or conceal them in a way that poses a typical hazard related to their electrical nature.

Answer:

C. They carry extremely high voltage
