In any case it poses an unacceptable risk in a coal mine. In addition to the immediate danger of injury and fire, there is the financial risk of interrupted operations, medical costs, equipment replacement costs, government fines and lawsuits. Effects of Arc Flash A phase-to-phase arc flash begins as an arc forms across an air gap.
