Which type of burn is caused by the high temperature generated by an electrical arc or explosion near the body?

• A. Arc Flash Burns
• B. Electrical Burns
• C. Thermal Burns
• D. Chemical Burns

Answer: (A)

Arc flash burns occur when an electrical arc or an explosion near the body releases intense radiant heat. The energy from the arc can reach extremely high temperatures in a fraction of a second, producing a flash of heat that burns the skin even without the current passing directly through the body. This is a distinct type of burn from other electrical injuries because the damage comes primarily from radiant heat and the blast nature of the arc, not from conduction of current through the body.

Electrical burns, by contrast, result from current entering and leaving the body, causing tissue damage along the path of the current and often creating entry and exit wounds. Thermal burns are a broad category caused by heat from any source, with arc flash burns being a specific, high-heat, near-body radiant heat event. Chemical burns come from exposure to corrosive chemicals, unrelated to electrical energy.
