Which of the following is a recommended safety practice when working on electrical circuits?

Using proper lockout/tagout procedures is a crucial safety practice when working on electrical circuits. This method ensures that all sources of energy to the equipment are properly isolated and rendered inoperative before any maintenance work begins. By locking and tagging the energy sources, it prevents accidental energization of the circuit, which could cause severe electrical shock, burns, or even fatal accidents. This systematic approach is an industry standard that enhances the safety of technicians and maintenance workers, making it essential for safe practices in any electrical work environment.

In contrast, working alone poses risks as having a second person could provide immediate assistance in case of an emergency. Wearing only rubber gloves is inadequate because it does not address other critical protective gear or practices necessary to minimize risk. Leaving tools scattered around the work area creates trip hazards and can lead to accidents, making it an unsafe practice in any work environment. Consequently, utilizing lockout/tagout procedures stands out as the best practice to ensure safety when handling electrical circuits.
