Where equipotential grounding is not feasible, how can protection be provided for underground distribution work?

When equipotential grounding is not feasible, utilizing voltage rated rubber gloves and blankets is the most effective method for providing protection during underground distribution work. These insulated tools and equipment create a barrier between the worker and any potential electrical hazards, thereby reducing the risk of electric shock.

Voltage rated rubber gloves are specifically designed to withstand high voltages and prevent electrical current from passing through to the wearer’s skin, while rubber blankets can be used to cover surfaces that might become energized, further isolating the worker from dangerous voltages. This personal protective equipment allows workers to safely handle electrical components and make repairs or conduct maintenance even in circumstances where other grounding methods are impractical.

Using insulated ladders, wearing heavy-duty boots, or ensuring that no one is nearby may offer some level of safety, but they do not provide the necessary electrical insulation and protection needed in situations where potential voltage hazards are present. Therefore, these alternative measures lack the effectiveness that insulated gloves and blankets provide against electrical risks during underground work.
