Which of the following is a sign of potential electrical hazards on site?

Frayed or damaged electrical cords are clear indicators of potential electrical hazards on a construction site. Such damage can expose wires, leading to electric shocks or short circuits, which pose serious safety risks to workers. Properly maintained electrical cords are essential for preventing accidents and ensuring that power tools operate safely.

In contrast, excessive clutter on work surfaces, unsecured tools, and inadequate lighting can create a hazardous work environment, but they are not directly linked to electrical safety concerns. Clutter and unsecured tools can contribute to tripping hazards and can hinder emergency response, while inadequate lighting can impair visibility and increase the risk of accidents generally, but they do not specifically indicate electrical risks like damaged electrical cords do.
