How does a 'hot stick' mitigate the risk of electrical shock during live-line switching operations?

A hot stick, also known as a live-line tool, is an insulated pole used by utility workers to safely perform switching, maintenance, and repair tasks on energized high-voltage power lines. It mitigates the risk of electrical shock by creating a large insulating barrier between the worker and the energized conductor. Hot sticks are typically made of fiberglass, which is an excellent electrical insulator. The length of the hot stick provides the necessary electrical clearance, ensuring that the worker remains a safe distance from the energized conductor. The tool end of the hot stick is designed to securely grip and manipulate various types of equipment, such as switches, disconnects, and conductor clamps. Workers are trained to use proper techniques to avoid creating a path to ground through their body. This includes wearing appropriate personal protective equipment (PPE), such as insulated gloves and sleeves, and maintaining proper clearances from grounded objects. By using a hot stick, the worker can perform live-line work without directly contacting the energized conductor, significantly reducing the risk of electrical shock. Regular inspection and testing of hot sticks are essential to ensure their integrity and insulating properties are maintained.
