What safety procedure must an operator follow before working on electrical equipment?

Before working on electrical equipment, it is essential to follow the lockout/tagout procedure for safety. This procedure ensures that the electrical equipment is properly de-energized and secured, preventing accidental re-energization while maintenance or repair work is being performed. Lockout involves physically locking the electrical switch or breaker in the off position, while tagging alerts others that the equipment is being serviced and should not be turned back on until the work is completed.

This safety procedure protects the worker from electrical shocks, injuries, or even fatal accidents. It is a critical step in ensuring that all energy sources are controlled and that workers can perform their tasks safely without the risk of unexpected electrical hazards.

Other options, such as merely activating systems or wearing insulated gloves, do not provide the comprehensive safety guarantee that lockout/tagout does. Checking for utility notifications is also important, but it doesn't address the immediate electrical safety concerns that lockout/tagout procedures directly mitigate.
