Phosphoric acid is highly caustic and irritating to eyes, mucous membranes and skin, causing severe pain and deep burns. Wounds heal slowly, with scars and skin inflammation. Intoxication may cause local and general damages. When handling phosphoric acid the following clothing should be worn: face cover or glasses, gloves and clothes made of acid-resistant cloth and rubber shoes. Spills of phosphoric acid should be washed with plenty of water or neutralised with milk of lime at 100 g CaO/dm3 concentration of solution with about 10% excess.
