Personnel performing electrical work on circuits 50 Volt or higher must attend OSHA 1910 Subpart S Training. NFPA 70E Training, commonly called Arc Flash Training, is required to be considered a "Qualified Electrician".
Others who need to understand NFPA 70E include EHS Managers, Maintenance Managers, Engineers, or anyone who is exposed to electrical equipment. NFPA 70E Training is needed to avoid the Electrical Hazards of Shock, Arc Flash, and Arc Blast.
