What issue may arise when using truck-mounted booms with non-insulated baskets during maintenance?

When using truck-mounted booms with non-insulated baskets during maintenance, one significant issue that may arise is the risk of multiple grounds. Non-insulated baskets do not provide electrical insulation, which means if the boom inadvertently contacts an energized power line, there is a potential for electrical current to flow through the equipment and into the ground. This situation can create multiple grounding points, leading to hazardous conditions for the personnel in the basket.

In such scenarios, workers may become part of the electrical circuit, posing serious risks of electrocution. Effective safety measures must ensure that insulated equipment is used when working on or near energized lines to prevent these dangerous conditions. Understanding this risk is essential for anyone involved in maintenance or repair tasks near high-voltage systems, as it factors heavily into the safety protocols necessary for such operations.
