What is the difference between arc flash and arc blast?

Arc flash is a sudden release of energy from an electrical fault that creates an intense burst of light and heat. It can cause burns, fires, and damage to equipment. On the other hand, arc blast is a pressure wave created by the arc flash that can cause physical damage to people and objects in the vicinity. It can cause hearing damage, concussions, and even death. In summary, arc flash is the initial event, while arc blast is the secondary effect that occurs due to the release of energy.
