What is the main hazard when working near overhead power lines?

• A. Falling objects hazard.
• B. Noise-induced hearing damage.
• C. Electrocution; maintain safe clearance and use a spotter when required.
• D. Slips and trips due to loose cables.

Answer: (C)

The main hazard is electrocution from overhead power lines. Electricity can arc or travel through any conductors or equipment that come too close, even without direct contact, making proximity a life‑threatening risk. The protective approach is to maintain a safe clearance between people and all parts of machinery and lines, and to use a spotter to guide movements and stop operations if the line is within unsafe distance. If possible, de-energize or relocate lines before work and treat any line as energized unless you have confirmed clearance. While other hazards like falling objects or trips can occur on a job, they are not as immediate or dangerous as the risk of electric shock when near power lines.
