Which statement describes the Arc-flash hazard most accurately?

Explanation:
Arc-flash describes the overall danger from an electrical arc, including the intense heat, light, and the blast that can injure nearby people. The arc-flash hazard captures both the thermal energy and the pressure wave produced by the arc, which is why it’s the most accurate term for describing the danger. The term arc-blast specifically refers only to the pressure pulse from the arc, not the entire hazard. An arc or a short circuit are conditions or events that can cause an arc, but they don’t name the hazard itself.
