The Nature of Electrical Arc Flash. • The intense heat from an arc causes the sudden expansion of air. This can result in a blast with very strong air pressure (lightning is a natural arc). • All known materials are vaporized at this temperature. When materials vaporize they expand in volume (copper— 67,000 times, water to steam—1,670 ...
