Limitations of approach to energized equipment guard in opposition to arc flash exposure; specifically intended flash-resistant apparel presents additional defense; grounding (earthing) clamps and chains are employed on line conductors to deliver a visual check here assurance that a conductor is de-energized. Personal protective machines presents electrical insulation and also protection from mechanical effect; gloves have insulating rubber liners, and do the job boots and tricky hats are specifically rated to offer protection from shock. If a technique can't be de-energized, insulated applications are made use of; even significant-voltage transmission lines may be fixed while energized, when required.[fifteen]
Electricians also can install and upgrade shops for protection purposes.
