What precaution should be taken when working with high voltages?

When working with high voltages, the primary concern is ensuring the safety of personnel involved in the work. Locking access to areas where high-voltage equipment is located restricts entry to authorized personnel only. This is crucial because it helps prevent accidental entry by untrained or unauthorized individuals who may not be aware of the hazards or safety protocols associated with high-voltage environments.

Maintaining a secure environment mitigates the risk of accidents and injuries, as those who work in those areas are typically trained and equipped to handle the dangers that high-voltage systems present. Safety protocols like access control are part of a broader strategy to manage risks associated with working in electrified areas, ensuring that only qualified personnel are present where they might encounter hazards.

The other options involve practices that are either inappropriate or potentially dangerous in the context of high-voltage work. For instance, removing grounding straps can significantly increase the risk of electric shock. Likewise, restricting work to utility personnel may not necessarily provide a complete solution, as people from various backgrounds can be trained to work safely with high voltage, provided they are authorized. Lastly, while confirming that voltages are safe before contacting live conductors is critical, it is equally important to establish controlled access to those areas to prevent unauthorized
