Classification of Burns What are the classifications of burns?
Burns are classified as first-, second-, or third-degree,
depending on how deep and severe they penetrate the skin's
surface. First-degree (superficial) burns First-degree burns
affect only the epidermis, or outer layer of skin. The burn site
is red, painful, dry, and with no blisters. Mild sunburn is an
example. Long-term tissue damage is rare and usually consists of
an increase or decrease in the skin color. Second-degree
(partial thickness) burns Second-degree burns involve the
epidermis and part of the dermis layer of skin. The burn site
appears red, blistered, and may be swollen and painful. Third-
degree (full thickness) burns Third-degree burns destroy the
epidermis and dermis. Third-degree burns may also damage the
underlying bones, muscles, and tendons. The burn site appears
white or charred. There is no sensation in the area since the
nerve endings are destroyed.
