What outcome is associated with improper handling of underground cables based on the testing done in vaults?

Improper handling of underground cables can lead to increased risk of electrical shocks, which is a significant safety concern for workers and personnel in proximity to electrical systems. When cables are not handled correctly, they may become damaged or exposed, creating pathways for electricity that can result in shocks. This is especially critical in vault settings where the risk of accidental contact with live electrical components is heightened.

In addition, improper handling may not only increase the potential for electric shocks but can also lead to other severe safety issues such as short circuits, fires, or even explosions in extreme cases. Therefore, ensuring that underground cables are handled correctly and tested thoroughly helps mitigate these risks and enhances overall safety during electrical work. This emphasizes the importance of training and proper procedures when working with underground cabling systems.
