An important safety consideration when working on high-voltage equipment is to always ensure that the equipment is properly grounded and de-energized. Grounding provides a safe path for electrical current to flow in case of a fault, which significantly reduces the risk of electric shock. Proper grounding prevents equipment from becoming energized unintentionally, which is critical when performing maintenance or repairs. De-energizing the equipment ensures that there is no electrical supply that could lead to dangerous situations during work. Both grounding and de-energizing need to be verified before beginning any work on high-voltage equipment to ensure the safety of the technician and those in the vicinity.

While using insulated tools, wearing rubber gloves, and keeping water away from the area are indeed safety measures that can enhance safety, they do not replace the foundational importance of grounding and de-energizing equipment in mitigating the risks of high-voltage work.
