When a worker contacts a line conductor while on an uninsulated truck-mounted platform, what occurs?

When a worker contacts a line conductor while on an uninsulated truck-mounted platform, they effectively create a pathway for electrical current to flow. This is because the human body can conduct electricity, and by making contact with the line conductor, the worker is now part of the electrical circuit. Since the worker is on a truck-mounted platform that does not provide electrical insulation, the body can act as a conductor to the ground, which is typically at a lower potential, resulting in the worker becoming a current path to earth.

Electrical safety protocols emphasize the importance of remaining insulated from any conductive materials and ensuring that workers are not in contact with live conductors to prevent accidental electrocution. Understanding this principle is crucial for the safety of workers in environments where they may encounter live electrical components.
