12.  More serious than First Degree Burn and involves the skin layers beneath the top layer.  Signs and symptoms: Blisters, severe pain, redness. Blisters may break open and the area is wet looking with a cherry red color.  Healing time: Depends on the severity of the burn.

13.  Most serious type of burn, involving all layers of the skin and underlying tissue.  Signs and symptoms: Surface appears dry and looks waxy white, leathery, brown or charred. Little or no pain may be felt. Area may feel numb at first because of nerve damage.  Healing time: Depends on severity of the burn.

15.  In general, 1) Cool the burn 2) Use large amounts of cool water to cool the burn 3) Cover the burn 4) Bandage loosely  For minor burns, which do not require medical attention, - Wash the burned area with soap and water, - Keep it clean and apply an antibiotic ointment.  For a victim of severe burns, - Lay him or her down unless he or she is having trouble breathing. - Raise the burned areas above the level of the victim's heart if possible, and protect the victim from drafts.
