Performing specific actions when working under voltage may result in mechanical damage to electric insulation gloves. Commonly used electrical insulating gloves are made of latex, which has relatively low mechanical resistance to punctures or cuts. Therefore, it is required to use protective gloves put on electrical insulating gloves. During work on live systems, ergonomics is very important. Often, the fitter works wearing three pairs of gloves at the same time: sweat-absorbing cotton insert, electrical insulating glove and leather glove. In this case, work ergonomics can be satisfactory only if, the shape and thickness of all types of gloves, including protective gloves, will be suited to electrical insulating gloves. Commercially-available leather gloves for protection against mechanical damage are not covered by the requirements relating to exposure to voltage or current and particularly to exposure to electric arc and the accompanying high temperatures. Furthermore, the standards that apply to protective gloves do not define such important parameters as the resistance to high temperature or moisture absorption by the protective glove material. Therefore, the method of selection of protective gloves for work on live systems is not specified by the standards and regulations and is often intuitive, because it depends on the experience and knowledge of the fitter or technical supervision.
