Acetic acid (AcOH) is corrosive and has a stimulating effect on eyes, respiratory tract, esophagus and stomach. It can cause vomiting, diarrhea, paralysis of the circulatory system, and even acidosis, uremia and hematuria, eventually leading to death. Acetic acid is soluble to lipids, so it can be absorbed by the skin. The infiltration of cells is also due to the almost total absorption of acetic acid by the human body, so the damage of eye mucosa and teeth can be clearly seen. Steam can irritate eyes, nose, throat and lungs. Inhalation of thick vapors can cause serious damage to the membranes of the nose, throat and lungs. Chemicalbook exposure to concentrated acetic acid can cause severe skin and eye damage, even blindness. Repeated or prolonged exposure to acetic acid irritates the skin, causes blackening, erosive front teeth, and may cause chronic inflammation of the nose, throat, and bronchus. Acute overexposure can cause bronchopneumonia and pulmonary edema. Chronic exposure can cause pharyngitis and catarrhal bronchitis. Ingestion, though unlikely in industrial production, can lead to perforation of the esophagus, vomiting of blood, diarrhea, shock, hemolysis, uremia, and death if left untreated.

When engaged in the production or use of glacial acetic acid, you should wear protective clothing, gloves and goggles. Eye flusher and safety indicator should be available for possible exposure. Contact with more than 50% acetic acid liquid, repeated or long-term contact with acetic acid content of 10-49% liquid Chemicalbook body should wear work clothes, wear protective glasses to prevent eye and skin contact with it. If the worker's skin is wet or polluted, it should be washed with soap and water immediately. If the work clothes are wet or polluted, it should be removed immediately. For liquids containing more than 5% acetic acid, an emergency eye wash should be prepared.
