What should tools used within the restricted approach boundary be?

Tools used within the restricted approach boundary must be insulated to protect the user from electrical shock. The restricted approach boundary refers to the area around exposed energized parts where special precautions must be taken to ensure safety. Using insulated tools helps to reduce the risk of accidental contact with live electrical components, which could lead to severe injury or even fatality.

Insulated tools are specifically designed to have a protective layer that prevents the flow of electricity through them, thus safeguarding the user. This insulation is critical in environments where live electrical work is performed, ensuring that even if the tool inadvertently comes into contact with an energized source, the user remains protected.

While non-conductive materials can offer some level of protection, the insulation provided by properly rated insulated tools is specifically tailored to withstand potential voltage levels encountered in electrical work, making them the safest option for use in risky environments.
