What should you do if a supply cable cannot be confirmed to be deenergized and you need to work on it?

Choosing to pierce, slice, or sever the supply cable at the work location poses an incredibly high risk because it can potentially expose workers to live electrical components if the cable has not been confirmed to be deenergized. This method does not prioritize safety and can lead to serious injury or fatality.

The correct approach is to notify the supervisor and wait for further instructions. This ensures that proper safety protocols are followed and minimizes the risk of electrical shock or accidents. A supervisor can coordinate with the appropriate personnel to confirm whether the cable is deenergized, allowing for safe work to proceed. This decision underscores the importance of communication and following established safety procedures in high-risk environments.
