Abstract: Though electrical incidents represent a relatively small percentage of all work-related incidents, they are disproportionately fatal and, in the case of burns, may result in extended hospitalization and rehabilitation. On average, approximately 5 to 10 arc flash explosions occur on the job every day in the United States. Proper protection is the key to reduce casualties during these incidents. IEEE 1584 and NFPA 70E are developed to protect the safety of the workers. Several areas of arc flash phenomena need further research and testing validation.

The IEEE and the NFPA (National Fire Protection Association) have joined forces on an initiative to fund and support research and testing to improve the understanding of arc flashes. The results of this collaborative project will provide information that will be used to improve electrical safety standards, predict the hazards associated with arcing faults and accompanying arc blasts, and provide practical safeguards for employees in the workplace. The identified areas include but are not limited to: 1) Heat and Thermal Effects, 2) Blast Pressure, 3) Sound, and 4) Light intensity.

This presentation will cover the basic understanding of the arc flash, performing the arcing current and incident energy calculation, and the procedures that have been carried out to provide information for the updating and clarifications of IEEE arc flash standards.
