Hydrogen chloride (HCl) is a colorless gas with a strong pungent odor. The white smoke in the air is easily soluble in water and becomes hydrochloric acid. It can interact with various metals and non-metals. The industries exposed to hydrogen chloride in industry include chemistry, petroleum, metallurgy, printing and dyeing, etc.
The effects of hydrogen chloride on the human body are divided into acute poisoning and chronic damage. Acute poisoning is more common in accidents, mainly manifested as headache, dizziness, nausea, sore throat, eye pain, cough, hoarse voice, difficulty breathing, chest pain, chest tightness, and sometimes hemoptysis. Severe cases can cause diseases such as chemical pneumonia, pulmonary edema, and atelectasis. Long-term operation in an environment with a concentration of more than 15mg/m3 will cause chronic lesions such as tooth erosion and chronic bronchitis.
For the prevention and control of hydrogen chloride, local ventilation and detoxification should be done, and personal protection should be strengthened.
