Which practice helps prevent electrical hazards during inspections?

Explanation:
The main idea is that electrical hazards are best prevented when a coordinated safety system is in place: proper grounding and bonding, appropriate overload protection, and lockout/tagout practices. Grounding provides a low-impedance path for fault currents, which helps keep exposed metal parts at a safe potential and reduces shock risk. Bonding ties all conductive surfaces to the same electrical potential, preventing dangerous voltage differences between parts that a worker might touch. Overload protection—such as fuses and circuit breakers—automatically interrupts current if it becomes excessive, reducing the chance of overheated conductors or fires. Lockout/tagout ensures that energy sources are fully isolated and cannot be re-energized while someone is inspecting or repairing equipment, so the work environment remains safe. In practice, using these together during inspections keeps equipment de-energized and safe, enables accurate and safe testing, and protects personnel from unexpected energization or electrical faults. Dismissing grounding requirements, failing to isolate energy sources, testing energized equipment without safeguards, or attempting to work without proper protective measures all increase the risk of shock, arc flash, and fires, which is why the cited combination is the best approach.
