A 35-year-old male sustains second and third-degree burns over 25% of his body surface area after an industrial accident involving a high-temp furnace. Initial on-scene management should include:
Cooling the burns with tepid water for 10-20 minutes, covering them with a clean, dry cloth, and managing pain.
Immersing the burned areas in cold water for extended periods to prevent further damage.
Applying topical antibiotics immediately to prevent infection.
Applying ice directly to the burns to reduce pain and swelling.
