In Arc Flash NFPA 70E Introduction and 2012 Update, you’ll learn …
- The science behind the arc flash phenomenon and potential causes for arc flash
- The relationship between an arc flash event and electrical power distribution system components
- The four arc flash boundaries or “limits of approach”
- The importance of Arc Flash Hazard Analysis and the course of action in the absence thereof
- PPE prescribed for the five arc flash hazard classes
Arc Flash is the sudden release of electrical energy through the air following a phase-to-phase or phase-to-ground fault. The core of an arc flash can reach temperatures of 5,000 degrees F.
This seminar covers the science behind the arc flash phenomenon, as well as the causes and the methods to protect personnel. 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.
The value of performing an Arc Flash Hazard Analysis is covered, as well as the recommended approach in the absence of a formal arc flash study. The four arc flash boundaries are discussed and illustrated. The seminar also covers the prescribed PPE for the five arc flash hazard classes, as well as arch flash terminology and labeling requirements.
Professionals who will benefit from this seminar include Electrical Engineers, Industrial Engineers, Maintenance Engineers, Safety Engineers, Safety Managers, Facilities Managers, Project Managers and other technical personnel who wish to enhance their knowledge about Arc Flash Hazards and NFPA 70E.
