Burns: First aid

When to get emergency help

Call 911 or your local emergency services or go to the emergency room if a burn:

  • Goes through all layers of skin.
  • Makes the skin look dry or leathery.
  • Makes the skin look charred, or has white, brown or black patches.
  • Is larger than 3 inches (about 8 centimeters) across.
  • Affects the face, hands, feet, genitals, buttocks or major joints, such as the knees, shoulders or elbows.
  • Wraps around an arm or a leg.
  • Happens along with smoke inhalation.
  • Starts swelling very fast.

Get emergency medical help for burns caused by electricity, lightning or strong chemicals. Even a minor burn may need medical attention if it affects the eyes, mouth, hands or genitals. Babies and older adults might need emergency care for minor burns as well.
