The following is a transcript of the Arc Flash Boundary infographic:
The 2018 edition of NFPA 70E describes these boundaries around electrical equipment. Identifying them can help to protect workers from electric shock and arc flash.
This is the distance from equipment at which an arc flash could cause second-degree burns. Unprotected workers should keep clear.
Workers without special training should stay outside this boundary, unless they have appropriate protection and are escorted by a specially-trained person.
Only specially-trained workers should cross this boundary. When work is to be performed on energized equipment, crossing this line requires an approved written work plan.
