Keep at a safe distance. Reduce the energy output from an incident. Carry out a risk assessment. Train on-site workers to control risks and interrupt faults. An effective way to help prevent arc faults is to use our 4P Model for arc flash hazard management: Predict, Prevent, Protect, Publish. Identify and calculate the potential risks.
ARC FLASH: A short circuit through air that flashes over from one exposed live conductor to another conductor or to ground. This electrical fault can create a dangerous release of energy, including thermal energy, acoustical energy, pressure wave or debris. ...

Approach Distances Arc Flash Boundary When an arc flash hazard exists, an approach limit from an arc source at which incident energy equals 1.2 cal/cm2 (5J/cm2). According to the Stoll skin burn injury model, the onset of a second-degree burn on unprotected skin is likely to occur at an exposure of 1.2 cal/cm2 (5J/cm2) for one second.
