What should be used when isolating underground cables?

Using voltage-rated rubber gloves or hot sticks is essential when isolating underground cables to ensure the safety of personnel working in potentially hazardous environments. These tools are specifically designed to provide electrical insulation and protect the user from electric shock.

Voltage-rated rubber gloves are made from materials that can withstand high voltages, making them suitable for use around live electrical components. They help create a barrier between the electrical source and the worker. Hot sticks, typically long insulated poles, allow workers to handle equipment or perform tasks from a safe distance, reducing the risk of contact with energized components.

In contrast, while insulated tools are necessary for many electrical jobs, they do not provide the same level of protection as voltage-rated gloves or hot sticks when dealing with underground cables, where high voltage and risks are prevalent. Non-conductive ropes can be useful for securing tools or equipment but do not provide any direct protection against electrical hazards. Uninsulated handling rods would significantly increase the risk of shock and must be avoided in such situations. Thus, voltage-rated rubber gloves and hot sticks are the appropriate choices for safely isolating underground cables.
