Electric arc incidents remain one of the most severe hazards faced by electrical workers worldwide. An arc flash can reach temperatures exceeding 19,000°C (35,000°F) — hotter than the surface of the sun — and can release massive energy in milliseconds. The result is intense thermal radiation, molten metal ejection, and explosive pressure waves capable of causing fatal injuries. https://www.aniarticles.com/62849-the-influence-of-seam-design-and-fasteners-on-arc-resistance-in
