• For the production of a variety of organic compounds,

Dilute acetic acid in the form of vinegar is harmless and
has been consumed by humans for centuries. Prolonged con-
tact with the skin or eyes may, however, produce irritation of
tissues and should be avoided. Concentrated forms of acetic
acid pose more serious health risks, such as irritation of the
gastrointestinal system, respiratory system, and eyes. Most
people do not come into contact with the concentrated acid,
and safety precautions are of importance only to individuals
who handle the material in their work.
