Abstract Chemical safety data sheet for nitric acid 50-70%. The 50-70% aqueous solution of nitric acid is a strong acid. lt is corrosive and reacts strongly with alkalis, metals and organic compounds. Inhalation causes irritation of the nose, throat and respiratory tract and may cause respiratory impairment and pulmonary oedema. Ingestion may cause immediate pain and burns of the mouth, throat, oesophagus and gastrointestinal tract. Contact with the eyes may cause redness, severe burns and irreversible damage. Contact with the skin causes redness and severe burns. Concentrated solutions may cause ulceration of the skin and yellow spots on the skin. Long periods of exposure to concentrated vapours may cause erosion and loss of the teeth and pulmonary damage (chronic pneumonia and bronchitis). Threshold limit values (ACGIH): 2ppm-5.2mg/m3 (TWA); 4ppm-10mg/m3 (STEL).
