What should be the main concern if poses a risk when scaffolding is near power lines?

When scaffolding is near power lines, the primary concern is electrocution hazards. This risk arises because scaffolding typically consists of metal, which conducts electricity. If the scaffolding comes into contact with a power line, there is a significant danger of electrical shock or even electrocution for workers on or near the scaffolding. It is crucial to maintain a safe distance from power lines and implement safety measures to protect workers, including using non-conductive materials when necessary and adhering to safety regulations regarding working near live electrical sources. Ensuring worker safety in these scenarios is paramount, as the consequences of electrical accidents can be severe and life-threatening.

Other concerns like cosmetic damage, structural integrity, or material costs may be relevant in different contexts, but they do not present the immediate and severe risk that electrocution does in this situation.
