This course caters to Professional Engineers, Non-Licensed Engineers, Technicians, Facilities
Managers, and other professionals who are interested in enhancing their understanding of arc
flash risk in their operations or those of their clients. This course is intended to serve as an
introduction, review and update on 2018 NFPA 70E based Arc Flash Standards and
Requirements. The course begins with an introduction to the general arc flash phenomenon.
The science behind the arc flash phenomenon is covered, coupled with discussion of potential
causes for arc flash and properties of an electrical power distribution system. Insofar as the
relationship between an arc flash event and the electrical power distribution system is
concerned, pertinent components such as fuses and breakers, and their role in initiation and
mitigation of an arc are explained. Value of arc flash risk analysis is covered, and
recommended approach in the absence of a formal arc flash study is explained. PPE
prescribed for the four (4) arc flash hazard classes, 1, 2, 3 and 4, is discussed. The three (3)
approach boundaries are discussed and illustrated. Arc Flash terminology and respective
definitions are reviewed. Arc Flash labelling requirements and methodology are explained.
This course is designed to serve as a tool for staying abreast of arc flash requirements with
highlights of revisions adopted in 2018. As such, this course can be used to satisfy the
Professional Development Hour requirements set forth by most US State Boards and other
licensure agencies; or simply, to meet periodic employee training requirements.
