Arc Flash Services

Arc Flash studies are essential for maintaining electrical safety and complying with NFPA 70E and OSHA requirements. These studies identify potential arc flash hazards, calculate incident energy levels, and provide critical data for accurate labeling, protective device settings, and appropriate PPE selection. NFPA 70E mandates that arc flash studies be updated every five years or after significant system changes, such as equipment upgrades or utility modifications. Regular maintenance and timely updates not only reduce arc flash risks but also protect personnel, enhance system reliability, and ensure your facility remains compliant with safety standards. At Shermco, we’re here to help you stay proactive with comprehensive, reliable arc flash solutions.
