Why is it advisable to use tools with insulated handles when working with electricity?

Using tools with insulated handles is advisable when working with electricity primarily because they provide extra safety against electrical shocks. Insulated handles are designed to prevent the flow of electrical current through the tool to the user. This insulation acts as a protective barrier, significantly reducing the risk of electric shock, which can occur if a person accidentally comes into contact with live wires or electrical circuits.

Electricity can be extremely dangerous, and using insulated tools adds a crucial layer of protection in environments where electrical hazards are present. It ensures that if the tool were to make contact with an energized source, the insulated handle would prevent the current from reaching the person using the tool.

The other options do not highlight the critical safety aspect of using insulated tools. While cost, usability, and efficiency can be considerations, they do not address the fundamental need for safety when working with potentially hazardous electrical systems.
