WebJul 23, 2024 · The goal of an arc flash assessment is to: 1) identify arc flash hazards, 2) estimate the likelihood of occurrence and the potential severity of injury or damage to … WebAn arc flash is a type of electrical explosion that occurs when an electric current leaves its intended path and travels through the air between conductors or between a conductor and the ground. This can happen when there is a fault in the electrical system, such as a short circuit or a broken wire.
