Which of the following options helps prevent injury during maintenance of electrical equipment?

Using proper grounding techniques is essential in preventing injury during maintenance of electrical equipment because it helps to ensure that any electrical faults or stray voltage are safely directed away from the worker and the equipment. Grounding serves as a protective measure, reducing the risk of electric shock and providing a safe path for current in case of a fault. Proper grounding techniques include verifying that equipment is properly grounded before work begins and using ground fault circuit interrupters (GFCIs) to enhance safety.

While wearing gloves, inspecting the worksite, and following manufacturer guidelines are also important safety practices, they focus on other aspects of safety. Gloves can provide protection against cuts, abrasions, and certain electrical hazards, but they do not eliminate the risk of electric shock without proper grounding. Inspecting the worksite is crucial for identifying hazards and ensuring a safe environment, but it does not directly address the risks associated with electrical circuitry. Following manufacturer guidelines ensures that the equipment is maintained and operated correctly but is secondary to the fundamental safety of grounding. Therefore, grounding techniques are a critical component in safeguarding workers during electrical maintenance.
