Which of the following is a sign of electrical hazard on a job site?

Loose cables on a job site can pose a significant electrical hazard because they can lead to tripping, electrical shorts, or exposure of live wires. When cables are not secured or managed properly, there is an increased risk of accidents resulting from workers inadvertently coming into contact with energized parts. This can lead to severe injuries or even fatalities through electrical shock or arc flashes.

In contrast, properly stored tools, clean work areas, and marked hazard areas are indicators of good safety practices and do not signify hazards. These practices help to create a safe work environment, reducing the risk of accidents and injuries related to electrical hazards and other safety concerns.
