The differences between electrocution and Arc Flash injuries-- &#; There are big differences between Arc Flash and electrocution injuries. An Arc Flash incident throws both a huge amount of thermal energy out, along with a strong blast that acts like an explosion. Injuries can result from getting hit by the thermal energy or getting caught in the blast. The energy in Arc Flash incidents can generate
