What must technicians do before beginning any electrical work?

Before beginning any electrical work, it is crucial for technicians to ensure the circuit is de-energized and locked out. This practice is founded on safety principles that aim to prevent electric shock or accidental equipment activation during maintenance or repair tasks. De-energizing the circuit means that all power sources are turned off or disconnected, significantly minimizing the risk of injury to personnel.

Locking out the circuit is equally important. This involves using lockout/tagout procedures, which ensure that once a circuit is de-energized, it cannot be turned back on until the work is completed and the lock is removed. This safety measure protects technicians by providing a visual and physical barrier against unexpected energization.

While checking tools, notifying supervisors, and wearing personal protective equipment are important safety practices, these actions should be taken after confirming the circuit is safely de-energized and properly locked out. Ensuring the worksite is safe from electrical hazards is the primary step in any electrical maintenance protocol.
