Ethanol is a flammable, volatile, colorless and transparent liquid with low toxicity at normal temperature and pressure. Long-term exposure to high-concentration ethanol in production can cause irritation symptoms of nose, eyes and mucosa, as well as headache, dizziness, fatigue, excitement, tremor and nausea. Long-term alcoholism can cause polyneuropathy, chronic gastritis, fatty liver, liver cirrhosis, myocardial injury, organic psychosis and so on. Long-term skin contact can cause dryness, desquamation, chapped skin and dermatitis.
Extended data:
First, the prevention and control of ethanol hazards:
(1) Skin contact: Take off the contaminated clothes and rinse the skin thoroughly with soapy water and clean water.
(2) Eye contact: Lift the eyelid and wash it with running water or normal saline. See a doctor.

(4) When eating too much, you should drink enough warm water to induce vomiting. See a doctor.
(5) Respiratory system protection: generally, special protection is not needed, and a filter gas mask can be worn when exposed to high concentration.
(6) Eye protection: wear chemical safety glasses.
(7) Hand protection: Wear rubber gloves.
(8) Alcohol fire extinguishing method: anti-soluble foam, dry powder, carbon dioxide and sand.
Second, the use of ethanol:
Ethanol can be used to make acetic acid, beverage, essence, dye, fuel and so on. Ethanol with volume fraction of 70%~75% is also a commonly used disinfectant in medical treatment, which is widely used in national defense chemical industry, medical and health care, food industry and industrial and agricultural production.
