A chemical burn occurs when living tissue is exposed to a corrosive substance such as a strong acid or base. Chemical burns follow standard burn classification and may cause extensive tissue damage. The main types of irritant and/or corrosive products are: acids, bases, oxidizers, solvents, reducing agents and alkylants. Additionally, chemical burns can be caused by some types of chemical weapons e.g. vesicants such as mustard gas and Lewisite, or urticants such as phosgene oxime.
Chemical burns may:
- need no source of heat,
- occur immediately on contact,
- be extremely painful, or
- not be immediately evident or noticeable
- diffuse into tissue and damage structures under skin without immediately apparent damage to skin surface

Famous quotes containing the words chemical and/or burn:
“If Thought is capable of being classed with Electricity, or Will with chemical affinity, as a mode of motion, it seems necessary to fall at once under the second law of thermodynamics as one of the energies which most easily degrades itself, and, if not carefully guarded, returns bodily to the cheaper form called Heat. Of all possible theories, this is likely to prove the most fatal to Professors of History.”
—Henry Brooks Adams (1838–1918)
“Most souls, ‘tis true, but peep out once an age,
Dull sullen pris’ners in the body’s cage:
Dim lights of life, that burn a length of years,
Useless, unseen, as lamps in sepulchres;”
—Alexander Pope (1688–1744)
