What are potential hazards when working with URD, according to the guidelines?

Working with underground residential distribution (URD) systems involves various potential hazards, which can significantly impact safety and operational efficiency. One such hazard is incorrectly sagged phases. This scenario can lead to dangerous situations, such as electrical faults or failures, resulting in outages or even injuries. When phases are not sagged correctly, they could come into contact with trees, structures, or other conductive materials, posing risks of electrical shock or fire.

The importance of proper phase sagging is emphasized in guidelines to ensure that wires maintain adequate clearance from the ground and other objects. This is crucial for both safety and functionality, as incorrect sagging can also affect the performance of the electrical distribution network.

In contrast, excessive visibility, proper equipment use, and excessive training do not represent hazards when working with URD. In fact, proper equipment use and adequate training enhance safety and performance, while visibility can aid in identifying hazards rather than creating them. Therefore, the focus on correctly sagging phases underscores the attention needed to maintain safety standards in URD operations.
