Is liquid acid harmful to human skin?

Sulfuric acid is a relatively common acid, which includes dilute sulfuric acid and concentrated sulfuric acid. No matter which type of sulfuric acid it is, it is highly corrosive. If the skin comes into contact with sulfuric acid, it will instantly become carbonized, which will cause great harm to the skin. Therefore, when using sulfuric acid, you must take protective measures. As an individual, try not to come into contact with such acid. Let's take a look at this aspect.

With the frequent incidents of people being splashed with sulfuric acid, everyone knows that sulfuric acid is highly corrosive. However, in daily life, we don’t see much sulfuric acid. However, sulfuric acid is widely used in the industrial field. However, there are many unscrupulous factories that secretly discharge sulfuric acid at night, polluting water resources and the environment, which is very hateful. So, for workers who work in sulfuric acid factories for a long time, is long-term exposure to sulfuric acid harmful to their health? Today, the editor will tell you about the harm of contact with sulfuric acid to the body, which is a corrosive item.

According to the editor, long-term inhalation of sulfuric acid gas is very bad for the body and harmful to health. In fact, sulfuric acid can harm the human body in three ways - skin, digestive organs and respiratory organs, and its harmfulness can be divided into acute and chronic.

Once the human body comes into contact with concentrated sulfuric acid, it will be burned immediately. If it enters the eyes, it may cause blindness in severe cases. Drinking sulfuric acid can cause serious damage to internal organs or death. If you inhale a large amount of hot sulfuric acid vapor or concentrated vapor released by fuming sulfuric acid, it will damage the upper respiratory tract and even the lung tissue, and in severe cases you will lose consciousness. The human body's sensitivity to this vapor varies from person to person. Usually, people will feel mild discomfort when it is in the range of (0.125~0.5)×10-6, obvious discomfort when it is in the range of (1.5~2.5)×10-6, and unbearable when it is in the range of (10~20)×10-6. Operators who are often exposed to low concentrations of sulfuric acid vapor will gradually become less sensitive to this type of stimulation, the so-called "acid resistance", and will be more susceptible to the poisoning of sulfuric acid vapor. Attention must be paid.

Contact with sulfuric acid can cause skin inflammation, and frequent inhalation of sulfuric acid vapor or mist can cause respiratory or bronchitis. Long-term inhalation of sulfuric acid vapor can cause tooth erosion, which first causes the enamel to lose its luster and then exposes the dentin, causing defects and blackening of the surface. Therefore, in the workplace, factories generally stipulate that the maximum concentration of sulfuric acid vapor should not exceed 1 mg/m3.
