What should be done to deal with leakage of carbon monoxide from the plant?
The hazardous and dangerous characteristics of carbon monoxide, carbon monoxide, is the Chinese name of CO. It is the product of incomplete combustion of materials. It is slightly soluble in water and soluble in various organic solvents such as ethanol and benzene. Mainly used in industrial chemical synthesis, such as synthetic methanol, phosgene, etc., or refined metal reducer. Occupation exposure to carbon monoxide in manufacturing steel and iron, coke, ammonia, methanol, graphite electrode, printing and dyeing factory, singeing, internal combustion engine powered coal mining blasting; non occupation contact is more extensive, such as household water heater was boiling water, winter coal, gas heating and so on, will produce carbon monoxide. Carbon monoxide is a flammable toxic gas known, but because of its physical and chemical properties of colorless smelly, so it is not easy to be aware of the harm, so it is not only the occupation killer, or the people's daily living potential. Carbon monoxide mixed with air can form an explosive mixture. When exposed to fire, high heat can cause combustion and explosion. Bottled carbon monoxide in case of high fever, increased pressure within the container, cracking and explosion. Because carbon monoxide has flammable properties, strong oxidizing agents and alkalis are its inhibitions. If the fire, should immediately cut off the gas source; if not immediately cut off the gas source, is not allowed to extinguish the burning gas.
The container should be cooled by heat in time. The harm to health, carbon monoxide and hemoglobin binding capacity than oxygen 200 times larger, after inhalation, in the blood and hemoglobin binding, interference blood carrying oxygen capacity, resulting in tissue hypoxia. The skin starts to become gray, and the skin and mucous membranes are red. Severe damage to brain cells can also cause secondary diseases, light damage to the heart, and damage to pyramidal or extrapyramidal systems, including the basal ganglia. Acute poisoning: mild poisoning are headache, dizziness, lethargy, tinnitus, palpitation, nausea, vomiting, weakness, abdominal pain, weakness and other symptoms; moderate poisoning in addition to the above symptoms, and complexion, lips cherry red, rapid pulse, irritability, instability of gait, fuzzy consciousness, coma patients remain unconscious;, miosis, muscle tension increased, frequent convulsions, incontinence, depth of poisoning due to respiratory paralysis and death. Chronic effects: the main manifestation of long-term inhalation of a certain amount of carbon monoxide, fatigue, irritability, indigestion and so on, can cause damage to the nervous and cardiovascular system. The compressed gas storage requirements in bottles, should be stored in a cool, ventilated warehouse, storage temperature should not exceed 300C; keep away from heat, avoid direct sunlight; and oxygen, compressed air, oxidant and stored separately; avoid mixed mixed transport. The lighting, ventilation and other facilities in the storage room shall be explosion-proof, and the switch is located outside the warehouse. Equipped with appropriate varieties and corresponding quantity of fire-fighting equipment.
