What must be done before working on energized electrical conductors?

Before working on energized electrical conductors, it is essential to ensure that the circuit is de-energized and locked out. This critical safety practice is mandated by regulations to prevent electrical shock or other accidents that could occur when working on live circuits. Lockout/tagout procedures involve isolating the energy source and securing it in a position that prevents accidental energization, which protects workers from potential hazards associated with live electrical systems.

While using insulated tools, wearing rubber gloves, and notifying a supervisor are important safety practices in the electrical field, they are not substitutes for de-energizing and locking out the circuit. Without de-energization, even with insulated tools or protective gear, the risk of severe injury remains significant. Ensuring the circuit is properly de-energized and locked out before any work is performed essentially forms the foundation of safe electrical work practices.
