Electricians wear specialized, heavily tested dielectric rubber insulating gloves (typically worn underneath protective leather outer gloves) to protect themselves against lethal electric shock and severe burns when working near energized components. These rubber gloves are engineered to withstand thousands of volts, acting as an impenetrable electrical barrier that prevents current from passing through the technician's hands and body if they accidentally brush against live bus bars, un-metered service lines, or energized transformer terminals during installation and maintenance work. Safety standards require these gloves to be routinely inspected, tested, and air-tested for punctures to ensure they maintain their life-saving insulation properties in the field.
