SECTION 2: Hazards identification

Emergency Overview: Colourless to light yellow liquid with pungent odour. Danger Corrosive. Extended contact with concentrated liquid or vapours can cause severe burns and permanent tissue damage. Inhalation of acid aerosols causes irritation to upper respiratory tract.

Principle Routes of Exposure

Eye and skin contact, inhalation. Eye: Low concentrations of mists or vapours can be irritating, causing redness. Concentrated mists, vapours or splashed liquid can cause severe irritation, burns and possibly permanent blindness.

Effects range from dermatitis, redness, swelling, pain, and permanent scarring, to death.

High or prolonged inhalation exposure may lead to corrosion of mucous membranes with temporary lung irritation and cough, difficulty in breathing, shortness of breath and/or pulmonary edema (fluid accumulation in the lungs). Prolonged inhalation may also lead to dental erosion. Fatality may occur from overexposure. Ingestion: Ingestion may cause severe acid burns to the mouth, throat, oesophagus, and stomach.
