What safety measure should you undertake while working near trolley wires?

When working near trolley wires, the most critical safety measure is to never work under bare wires. This is essential because bare trolley wires are live and can carry high voltage, posing a significant risk of electrocution or serious injury. If someone is situated directly underneath these wires, there is a chance of accidental contact, which can be fatal. Ensuring that individuals maintain a safe distance from bare wiring minimizes the risk of electrical hazards, thus safeguarding their well-being.

While using heavy gloves or specialized helmets may provide some protection in certain situations, they do not fundamentally eliminate the risk associated with live trolley wires. Additionally, informing team members is a good practice for safety and communication, but it does not address the immediate and personal risks of working directly under energized power lines. Therefore, the emphasis on the critical nature of maintaining safe distances from bare wires is paramount to ensuring safety in such work environments.
