Arc and flash burn hazards at various levels of an electrical system

This paper discusses the effect on humans of arcing and flashing from high-energy electrical equipment. It reviews the results of a survey of several large petrochemical facilities in the US about personal protective equipment (PPE) and other equipment used for protection from arcing and flashing. This paper also presents the results of calculations done for typical industrial and large commercial electrical distribution systems and supports the use of personal and other protective equipment for work performed on or near high-energy electrical equipment.
