What is a key factor to consider when working with high voltage equipment?

When working with high voltage equipment, the use of insulated gloves is crucial for safety. High voltage poses significant risks, including electric shock and injury from accidental contact with live parts. Insulated gloves are specifically designed to protect workers from these hazards, ensuring that they can safely handle electrical components without the risk of electrical current passing through their bodies.

In addition to this, it's essential to wear appropriate personal protective equipment (PPE) because it serves as the first line of defense against potentially dangerous situations. While other options may also be relevant to safety and operational efficiency, the primary focus on insulated gloves underscores their importance in preventing life-threatening injuries when dealing with high voltage scenarios.

Factors like understanding the layout of power lines or aesthetic considerations may have operational relevance but do not directly address the immediate physical dangers involved in high voltage work. Furthermore, operating alone contradicts safety protocols that advocate for a buddy system, enhancing safety and response measures in case of emergencies.
