What safety measure should be taken when working with grounding systems?

When working with grounding systems, the most important safety measure is to always de-energize circuits before making connections or repairs. This practice minimizes the risk of electrical shock, reduces the potential for arc flash, and provides a safer working environment for personnel involved. De-energizing circuits ensures that workers can safely handle and inspect the grounding connections without the immediate danger posed by live electrical components.

In grounding and bonding work, it is crucial to be aware of potential hazards. Working on live circuits can lead to significant safety risks, such as electrical shock or serious injuries. Using rubber gloves without de-energizing circuits does not eliminate the inherent risks associated with live work. Additionally, making repairs without prior testing can result in accidents and does not follow best safety practices. Proper procedures require that systems be thoroughly checked and confirmed to be de-energized before starting any work. This approach is a fundamental principle in maintaining safety and preventing electrical accidents.
