Engineering Webinar Series: Overview of Arc Flash

May 14, 2024

Who Should Attend:

Engineering personnel and others who would benefit from an understanding of current electric utility engineering principles and practices.

Webinar Overview:

OSHA requires employers to analyze and protect their employees from risks associated with arc-flashes. OSHA and NESC guidelines have changed over the years and different methods exist for making the necessary arc-flash calculations. Historic guideline changes will be reviewed as well as the applicability and limitations of the different calculation methods. The presentation will discuss the steps needed to make an arc-flash study including information needed, establishing work zones, methods for assessing incident energy levels, work rules and their impacts, examples of actual calculations and use of table values, mitigation methods, and protective gear options and applicability.
