The harm of dichloromethane to human body

The rapid development of science and technology in modern life has enabled people to manufacture various advanced substances through human means. For example, dichloromethane is a commonly used substance in modern life. It is widely used in the industrial field and is an indispensable industrial raw material. However, this substance is corrosive and toxic, which is harmful to people's health. Let's take a look at whether dichloromethane is harmful to the human body?

Dichloromethane, dichloromethane, molecular formula CH2Cl2, molecular weight 84.93. Colorless transparent liquid with a pungent ether-like odor. Insoluble in water, soluble in ethanol and ether. It is a non-flammable low-boiling point solvent, often used to replace flammable petroleum ether, ether, etc.

Toxicity: Dichloromethane is of low toxicity and has anesthetic effects. It can cause paralysis of the respiratory and circulatory centers and pulmonary edema. Although dichloromethane is of low toxicity, it can decompose into hydrochloric acid, carbon dioxide, carbon monoxide and highly toxic phosgene when it enters the human body and encounters heat and moisture, increasing the harm to humans. Lack of effective protective measures or leakage during production may enter the body through the respiratory tract, skin mucosa and digestive tract, causing acute or chronic poisoning. After human poisoning, the main damage is to the nervous system. Mild symptoms include nausea, vomiting and headache, while severe cases can lead to pulmonary edema and arrhythmia. Respiration stops and the central nervous system is depressed. Patients with severe cerebral edema may experience epileptic convulsions, mania, coma, and liver and kidney damage.

This product has anesthetic effects, mainly damaging the central nervous system and respiratory system. The primary route of human exposure is by inhalation. If dichloromethane splashes directly into the eyes, it will be painful and corrosive. The vapor of methylene chloride has an anesthetic effect. When there is a serious risk of poisoning, you should immediately break away from contact and move to fresh air. Some poisoning symptoms will be alleviated or disappear, and no lasting damage will be caused.

Eye protection: Wear chemical safety glasses when necessary.

Body protection: Wear anti-poison penetration work clothes.

Hand protection: Wear chemical-resistant gloves.

Others: Smoking, eating and drinking are prohibited at the work site. After work, take a shower and change clothes. Store contaminated clothing separately and wash it for later use. Pay attention to personal hygiene.
