Chlorine poisoning

clinical manifestations of acute poisoning is divided into mild poisoning, moderate and severe poisoning. Mild poisoning world pie network information , mucous membrane irritation, redness, tearing, coughing, visible conjunctival, nasal and throat congestion. But the lungs without special see. Gradually improved after a few hours, the symptoms disappeared after 3 ~ 7d. Moderate poisoning, inhalation of high concentrations of chlorine and immediately caused a diffuse bronchitis or bronchial pneumonia. After treatment, 3 ~ 4d can be improved, 10 days cured. Severe poisoning, inhalation of high concentrations of chlorine may develop pulmonary edema, may also cause coma and shock. Can cause severe laryngeal spasm and edema, can cause choking and can cause reflex respiratory depression, and even cardiac arrest.

Chlorine poisoning (chlorine poisoning)

toxicological chlorine moderately soluble in water. Low concentrations, only infringement of the eyes and upper respiratory tract, burning and stimulating effect on the local mucosa. Caused by inflammatory swelling, hyperemia, and conjunctival irritation. Serious accidents, the high concentration of chlorine or longer contact time, and can often cause deep respiratory tract lesions: bronchiolitis, peribronchial inflammation, pneumonia and toxic pulmonary edema; and irritates mucous membranes and peripheral receptors, can cause localized muscle spasm, exacerbate ventilation barriers and lack of oxygen. Chlorine can also damage the central nervous system, caused by autonomic dysfunction after inhalation of high concentrations of chlorine, cause vagal reflex cardiac arrest, electric shock-like death.

diagnostic principle of short-term inhalation of a large number of chlorine rapid onset of clinical symptoms, signs, chest x-ray findings, a comprehensive analysis to rule out other causes of respiratory disease before the diagnosis of acute chlorine poisoning.

physicochemical properties chloride as yellow-green gas with strong pungent odor, soluble in water, the density 2.49kg/m3, boiling point -34.6 ℃. Chlorine easily liquefied dark yellow liquid, the liquid density 1.56kg/m3 (34.6 ° C), vapor pressure increased with temperature increase. Dry chlorine at low temperatures is not very lively, but the water first to generate hypochlorous acid and hydrochloric acid, hypochlorous acid can be further decomposed into hydrochloric acid and the new eco-oxygen, which is the basic reaction of chlorine as the oxidant.

acute chlorine poisoning can occur with bronchial asthma or asthmatic bronchitis. Skin contact with liquid chlorine burns may occur or acute dermatitis.

accessibility electrolytic salt; the use of chlorine to manufacture chlorinated compounds such as hydrochloric acid, bleaching powder, phosgene, chlorobenzene, BHC, 2 23; pigments, leather tanning, pharmaceutical industry can be exposure to chlorine; paper, printing and dyeing industry. Grease and animal bones in the process of bleaching, water disinfection.

treatment principles (1) immediately from the scene, to keep quiet and warm. Attention to discover the early changes in condition, chest x-ray examination, if necessary, for timely processing. Appear to stimulate the reaction, observed at least 12h, poisoned patients should rest in bed, avoid activities sicker. ECG when necessary for the treatment of referenceWorld Steel Pipe . (2) the principle of first aid treatment and Internal Medicine.

Chinese industrial enterprise health standards under the workshop 1mg/m3.

suction phenomenon of chlorine due to acute damage to the respiratory system lesions. Mild manifestations of chemical tracheitis, bronchitis or bronchial inflammation around; heavier chemical bronchitis, interstitial pulmonary edema, the limitations alveolar pulmonary edema or asthmatic bronchitis; with severe manifestations of serious chemical bronchopneumonia, pneumonia, alveolar pulmonary edema.

chlorine chronic, referring to the long-term exposure to low concentrations of chlorine irritation, chronic bronchitis common.
