The goal of this week's presentation is to help all individuals better understand arc flash hazards and how they are calculated regardless of previous technical and engineering knowledge. David will provide visual representations to better explain arc flash hazards, how they are calculated, the importance of PPE, and real-world examples of incidents. After attending this session, one should have a better overall understanding of key factors that determine arc flash hazard incident energy levels and PPE requirements.
