Run cool water over the burn for at least 15-20 minutes. If running water isn't available, apply a clean, wet compress.

Keep any blisters intact to protect the raw skin underneath from infection.

Elevate the burned arm or leg above heart level to limit fluid accumulation and throbbing.

Have the patient drink water to stay hydrated. Keep them warm and calm.
