• A. First or Second Degree Burns
• B. Third Degree Burns
• C. Superficial Burns
• D. No Burns

Answer: (A)

Burn depth follows how long and how intensely the skin is exposed. A flash from an explosion delivers a very short heat pulse, so it typically damages only the outer skin layers. That means most injuries are limited to first-degree burns (affecting the epidermis, red and painful) or second-degree burns (partial-thickness, involving part of the dermis and often with blisters). Deeper, third-degree burns—full-thickness involving the entire dermis or deeper—usually require a longer exposure or a stronger heat source than a brief flame front provides. No burns would not fit an explosion scenario, while superficial burns are possible but describe only the mildest end. So the typical extent from a brief explosion flame front is first or second-degree burns.
