Which safety precaution should always be followed when working around electricity?

The practice of removing jewelry and metal-framed glasses when working around electricity is essential for safety. Metal can conduct electricity, and wearing items like rings, bracelets, or watches increases the risk of electric shock or severe injury if an electrical fault occurs. Similarly, metal-framed glasses could conduct electricity if they come into contact with a live circuit. The goal of this precaution is to mitigate the risk of accidental conduction of electrical current through the body, which could lead to serious injuries or fatalities.

While wearing gloves and goggles can provide protection against other hazards in some situations, they do not directly address the risks related to conducting electricity. Keeping water nearby is generally dangerous around electricity since water is a conductor. Using insulated tools is a good safety practice as well, but removing jewelry and metal objects is a more fundamental precaution to prevent direct electrical hazards.
