What characterizes an insulated handling tool?

An insulated handling tool is primarily characterized by being constructed from non-conductive materials, which serve to protect workers from accidental contact with live electrical components. This is crucial in environments where electrical hazards are present, as using non-insulated tools could lead to serious accidents or injuries through electrical shock. Insulated tools are designed to provide an extra layer of safety for workers who are often working in close proximity to high-voltage systems.

While tools that are lightweight and easy to maneuver (as mentioned in another option) can be beneficial for various tasks, their weight does not directly correlate to the insulated nature of the tools. Similarly, tools designed specifically for high-voltage applications may include insulation, but not all insulated tools are confined to high-voltage use. Lastly, the characteristic of being used primarily for overhead line work does not define an insulated handling tool, as insulated tools can also be used in various applications across the electrical field.
