 To determine the need for referral to a specialized burn unit , the American Burn Association devised a classification system . Under this system , burns can be classified as major , moderate and minor . This is assessed based on a number of factors , including total body surface area affected , the involvement of specific anatomical zones , the age of the person , and associated injuries . Minor burns can typically be managed at home , moderate burns are often managed in hospital , and major burns are managed by a burn center .
