A caustic substance is a chemical (particularly alkalis) with the ability to burn or corrode through materials. Many substances are caustic such as Sodium Hydroxide, Potassium Hydroxide or Calcium Oxide. If a caustic substance comes in contact with skin or eyes the damage can be irreversible or even fatal.
