A burn injury usually results from an energy transfer to the body. There are many types of burns caused by thermal, radiation, chemical, or electrical contact.
Thermal burns: Burns due to external heat sources which raise the temperature of the skin and tissues and cause tissue cell death or charring. Hot metals, scalding liquids, steam, and flames, when coming in contact with the skin, can cause thermal burns.
Radiation burns: Burns due to prolonged exposure to ultraviolet rays of the sun, or to other sources of radiation such as x-ray
Chemical burns: Burns due to strong acids, alkalies, detergents, or solvents coming into contact with the skin and/or eyes
Electrical burns: Burns from electrical current, either alternating current (AC) or direct current (DC)
