An arc flash is an electrical accident that creates a high-temperature explosion. It can vaporize surrounding metal, set fires, and result in severe burns. Although rare, arc flashes can have grave consequences so you need to ensure your people and site are always protected. An arc flash can happen during abnormal use due to a corruption of ...
The arc flash boundary is calculated to 1.2 calories/cm2 of incident energy. That’s the distance where a worker without appropriate PPE would receive second-degree burns. Sometimes this boundary is the furthest one from the exposed equipment, other times the limited approach boundary is the furthest out. When the arc flash boundary is the ...
