The arc flash analysis must be updated when a major modification or renovation takes place. This standard requires electrical equipment owners to perform arc flash hazard analysis to determine the arc flash boundary, the incident energy at the working distance, and the personal protective equipment (PPE) that employees within the arc flash boundary must use. The guidelines for work involving electrical hazards and the selection of arc flash protective equipment are provided by National Fire Protection Association (NFPA) standard 70E. The program was established to develop the standard procedures for the implementing of and continuing compliance with the national and industry standards governing electrical safety. The Facilities Operations and Maintenance division of Facilities Services has been charged with developing an Arc Flash Analysis Program (AFAP) on behalf of the university. Certain burn injuries can occur even when adequate PPE is employed, and the recommended PPE may provide little or no protection against arc blast and its effects when circuits or equipment have not been placed in an electrically safe work condition. The arc flash hazard analysis and recommended PPE levels are no substitutes for safe work practices.
It must be reviewed periodically, not to exceed five years, to account for changes in the electrical distribution system that could affect the results of the arc flash hazard analysis.
The study is prepared by an electrical engineer and conducted for the purposes of injury prevention and determination of safe work practices, arc flash boundary, and appropriate levels of personal protective equipment (PPE). Arc flash analysis is a technical study investigating a worker’s potential exposure to arc flash energy.
