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:
Applying ice directly to the burns to reduce pain and swelling.
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.
