What is a critical safety measure to prevent electrical accidents in linework?

Wearing rubber gloves is a critical safety measure in linework because they provide electrical insulation and protect the lineman from electrical shock when working on or near energized lines. Rubber gloves are specifically designed to withstand high voltage and are tested for their dielectric strength, ensuring that they can safely isolate the worker from electrical currents. This measure helps to prevent serious injuries or fatalities that can occur from accidental contact with live electrical components.

While ensuring equipment is energized is an important operational aspect, it does not contribute to safety and can lead to dangerous situations if not managed carefully. Proper equipment inspection is essential to ensure that tools and equipment are functioning correctly, which contributes to overall safety, but it does not provide direct protection during electrical work as rubber gloves do. Staying hydrated, while important for general health and performance, does not specifically address the risks associated with electrical hazards.
