Emergency treatment of chemical leakage

1n the process of production, storage and use of chemicals, the containers containing chemicals often have some accidents, such as rupture and spillage, which cause the leakage of dangerous chemicals. Therefore, it is necessary to take simple and effective safety technical measures to eliminate or reduce the risk of leakage. 1f the leakage can not be controlled or handled properly, it may turn into combustion, explosion, explosion and other accidents at any time Poisoning and other malignant accidents. The following describes the chemical leakage must take emergency measures

first, evacuation and isolation

in the process of chemical production, storage and use, in case of leakage, it is necessary to evacuate irrelevant personnel and isolate the leakage contaminated area. 1f there is a large amount of flammable and explosive chemicals leakage, at this time, we must call “119” to call the police, request fire professionals for rescue, and protect and control the scene< Cutting off the fire source is particularly important for the treatment of chemical leakage. 1f the leakage is flammable, all kinds of fire sources in the leakage pollution area must be eliminated immediately 111. personal protection the personnel participating in the leakage treatment should have a full understanding of the chemical properties and reaction characteristics of the leakage products, and handle them at high places and windward places. 1t is strictly forbidden to act alone and have a guardian. Cover with water gun (fog water) if necessary. According to the nature of the leakage and the form of poison contact, appropriate protective equipment should be selected to prevent casualties and poisoning accidents in the process of accident handling 1. Respiratory system protection in order to prevent toxic and harmful substances from invading the human body through the respiratory system, different protective devices should be selected according to different occasions oxygen respirator, air respirator, air supply type long pipe mask, etc. must be used for leaking chemicals with high toxicity, high concentration and lack of oxygen gas masks can be used when the concentration of oxygen in the leakage is not less than 18% and the concentration of poison is within a certain range (isolation gas masks are used when the concentration of poison is less than 2%, direct gas masks are used when the concentration is less than 1%, and gas masks are used when the concentration is less than 0.1%). Dust mask can be used in dust environment

3. Solid leakage treatment

collect the leakage with appropriate tools, and then wash the contaminated ground with water< 1n modern industry, chlorine is obtained by electrolysis of salt, and the laboratory is equipped with hydrochloric acid and manganese dioxide. Chlorine is yellow green with pungent odor, soluble in water. Chlorine does not burn in the air, but most general combustibles can burn in chlorine, just as they burn in oxygen, general flammable gas or steam can also form explosive mixture with chlorine. Chlorine can react violently with many chemicals, such as acetylene, turpentine, ether, ammonia, fuel gas, hydrocarbon, hydrogen, metal powder and so on to produce explosion or explosive products. 1t can corrode almost all metals and nonmetals. Chlorine is widely used in our institute and is one of the important raw materials for scientific experiments. Because of the danger of chlorine gas, if it is used, transported and managed improperly, it is easy to cause accidents 1. characteristics of chlorine leakage hazard: 1. 1t is sudden and has a large amount of gas leakage without any sign before leakage
