This Two-Day class addresses the major topics associated with medium and high voltage electrical safety based on OSHA 1910-269. Although each OSHA topic will be covered which includes some non-electrical topics, the primary focus will be on electrical topics and electrical safety when working on or near exposed energized conductors. Arc flash protection and shock protection will be addressed as well as determining the necessary PPE. Various incident energy analysis methods as outlined in Annex E will be discusses as well as several in-class examples. Calculation examples will be provided based on the changes in minimum approach distance calculation methods.
