What hazard can overhead lines present?

• A. Noise.
• B. Electrocution risk from contact with or proximity to live overhead lines.
• C. Tripping hazard.
• D. Mangroves.

Answer: (B)

Overhead lines carry live electrical current. The main hazard is electrocution from contact with the line or from arcing if you or conductive equipment get too close. Electricity can jump through air or travel via equipment that bridges to the line, so it’s essential to keep a safe clearance, treat all lines as energized until proven otherwise, and follow proper precautions like using spotters and maintaining established distances. While noise, tripping hazards, or unrelated things like mangroves can exist in the work area, they are not the specific danger posed by overhead lines—the immediate risk is electric shock or electrocution from proximity to live conductors.
