Electronic level CL2
First, product introduction
The chlorine gas is yellow green under normal temperature and pressure. It has a strong irritating odor of poisonous gas. The density is larger than the air. It is soluble in water and easy to compress.
Liquefied liquid chlorine, which is one of the main products of the chlor alkali industry, can be used as a strong oxidizer. Chlorine gas does not burn in the air, but it is burning.
Gas. Most of the general combustibles can be burned in chlorine gas. The dry chlorine gas is not very active at low temperature, but the first man becomes hypochloric acid and salt when he meets the water.
Acid, hypochlorous acid can be decomposed into hydrochloric acid and nascent oxygen, which is chlorine as the basic reaction of oxidizing agent. A general combustible gas or vapor.
All can form an explosive mixture with chlorine gas, which can explode by sunlight, heating, or Mars. Completely dry chlorine gas at normal temperature
Iron does not work, but water - containing chlorine can corrode most of the metal headed by iron. Ammonium chloride is produced when the cloth impregnated with ammonia is exposed to chlorine gas
Smoke, this phenomenon can be used for leak detection of gas. Chlorine is dissolved in water, alkali solution, carbon disulfide, carbon tetrachloride and ethanol.

Four, the application of chlorine gas
Chlorine is mainly used in the manufacture of organic and inorganic chlorides, pesticides, solvents, disinfectants, bleaching agents, decontamination agents, production of glycerol, and plastic
Materials, spices, pesticides, medicines, and rubber are used for smelting, drying, fiber, crystal growth, thermal oxidation, standard gas, correction gas, etc. High purity chlorine
Gas is mainly used in the electronics and semiconductor industries.
Five. Precautions
Store in a cool, ventilated storeroom. Stay away from fire and heat. The temperature of the storeroom should not exceed 50 degrees centigrade; it should be separated from the inflammable and oxidizing agent
Storage, avoid mixed storage. The storage area should be equipped with leakage emergency treatment equipment. The operator must undergo special training and strictly abide by the operating rules. Cylinder bottle
A neck cylinder inspection time, does not meet the requirements of the cylinder should be entrusted ferrill specialty gas supplier to the pressure vessel inspection unit qualification for inspection
Check. The use of overdue steel bottles is strictly prohibited.
Six. Leakage of emergency treatment
Chlorine leak occurs, should rapidly evacuate workers of contaminated area to windward, and separate the gas until the end, Dai Zhengya proposed emergency personnel
Self-contained breathing apparatus, the chemical protective clothing that is specially recommended by the manufacturer (completely isolated). Avoid contact with acetylene, turpentine, ether, ammonia and other substances. cut off
The gas source, spray water dilution, dissolution, build a barrierpit to contain a large number of wastewater generated. If possible, the residual gas or leakage gas is sent to the exhaust fan.
To a washing tower or a ventilator connected to the tower. If possible, the leakage is guided to a reducing agent (acid sodium sulfate or acid sodium carbonate) with a pipe. also
The gas leaking cylinder can be placed in the lime emulsion. The gas leakage container is not reusable and is treated by technology to remove the possible remaining gas.
Seven, first aid measures
Inhalation: immediately break away from the scene to the fresh air, keep quiet and keep warm. Rinse thoroughly with clear water when the eye or skin is exposed to liquid chlorine. After inhalation
At least 12 hours were observed and symptomatic treatment. Intake of more should stay in bed, give oxygen, salbutamol aerosol, salbutamol or 5% sodium bicarbonate plus
Dexamethasone is inhaled by atomization. Rational oxygen therapy should be used in acute poisoning; early, appropriate and short term adrenocorticosteroids are used to keep the respiratory tract unobstructed.
Prevention and treatment of pulmonary edema and secondary infection. See the treatment of acute irritant gaseous pulmonary edema
Eye and skin burns are treated by acid burns. See the treatment of chemical burns and the treatment of chemical skin burns.
