What do you do if you have a really bad burn?

If you have a really bad burn, it's important to seek medical attention immediately. While waiting for help, you can cool the burn by gently rinsing it with lukewarm water for 10-20 minutes, but avoid ice or very cold water. Cover the burn with a clean, non-stick bandage or cloth to protect it from infection. Do not apply ointments, butter, or other home remedies, as these can worsen the injury.
