Professional Answer: Working near power lines presents a high-risk environment. The primary hazards are:

• Electrical Shock/Electrocution: This is the most serious risk, often caused by accidental contact with energized conductors, either from above or from damaged underground lines.

• Arc Flash: A sudden electrical discharge can cause a powerful explosion, leading to severe burns and other injuries. To mitigate these risks, a strict safety protocol is non-negotiable.

• De-energize Lines: Whenever possible, confirm that all lines and circuits in the work area have been de-energized and properly grounded.

• PPE: Always wear appropriate personal protective equipment, including insulated gloves, flame-retardant clothing, and safety glasses.

• Site Planning: For both overhead and underground projects, a comprehensive site plan must identify and clearly mark all energized lines.
