Health protection in sulfuric acid plants

Sulfur dioxide is a colorless gas with moderate irritancy, primarily affecting the respiratory tract. Inhaling sulfur dioxide can impair respiratory function and exacerbate existing respiratory diseases (especially bronchitis and cardiovascular diseases). In those who are susceptible, in addition to changes in lung function, there are also obvious symptoms such as wheezing, shortness of breath, and coughing. The main preventive measure is to wear proper protective gear. *You get used to it. I have been working in the acid production industry for over 10 years, and I have been exposed to sulfur dioxide on many occasions without any problems.

Sulfur dioxide is a colorless gas with strong irritant properties. When inhaled, it causes immediate symptoms such as choking coughs or persistent coughing, shortness of breath, tearing, sensitivity to light, and sore throat. Inhaling high concentrations of sulfur dioxide gas can also cause hypoxia symptoms such as blueing of the lips and nails, as well as dizziness, nausea, vomiting, and difficulty breathing. In severe cases, pharyngeal edema, pneumonia, and pulmonary edema may occur, and shock and coma can even set in immediately. Redness and swelling occur at the areas of the skin where it is directly stained, and in some cases blisters or erosions may form. Sulfur dioxide adheres to the conjunctiva of the eye, forming an acid that has a strong irritating effect. Inhaling sulfur dioxide can irritate the respiratory tract and cause nasopharyngitis, tracheitis, and bronchitis. Prolonged exposure to sulfur dioxide can lead to chronic respiratory inflammation and dental caries. In general, in the workplace, the sulfur dioxide concentration in the air is not allowed to exceed 0.02 g/m³. Therefore, operation areas in sulfuric acid plants generally need to have good ventilation. The equipment must not have any leaks. It is said that in some sulfuric acid plants, the window glass in the workshops was broken. Some people joked that this was done to ensure good ventilation and protect the health of the workers. In fact, the protective measures are quite simple: as long as there are areas where air leakage occurs during production, wearing a gas mask is the best solution.
