Hydrochloric acid has many uses. It is used in the production of
chlorides, fertilizers, and dyes, in electroplating, and in the
photographic, textile, and rubber industries. Hydrochloric acid
is corrosive to the eyes, skin, and mucous membranes. Acute
(short-term) inhalation exposure may cause eye, nose, and
respiratory tract irritation and inflammation and pulmonary edema
in humans. Acute oral exposure may cause corrosion of the mucous
membranes, esophagus, and stomach and dermal contact may produce
severe burns, ulceration, and scarring in humans. Chronic
(long-term) occupational exposure to hydrochloric acid has been
reported to cause gastritis, chronic bronchitis, dermatitis, and
photosensitization in workers. Prolonged exposure to low
concentrations may also cause dental discoloration and erosion.
EPA has not classified hydrochloric acid for carcinogenicity.
