MSDS - safety technics instruction of chemicla ethanol hylic physic chemical constantInternational Standard NO: 32061: 64-17-5Chinese name：ethanol English name：ethyl alcohol；ethanol Another name：alcohol Molecular formula：C2H6O；CH3CH2OH Molecular weight: 46.07Melting point： -114.1 Boiling point：78.3? Density：relative density (water =1)0.79； Steam tension：12 Solubility：hydrated，organic solvent can use for ether,chloroform, glycerin and so on.Stability：steady Appearance and characteristic: achromatous liquid，with bouquet Risk markings： 7(flammable liquid) Application：use for mixed liquor、organic synthesis、disinfection as menstruum Influence On EnvironmentalHealth hazardRoute of entry：breathe in、ingestion、skin absorption.Health hazard：This product is central nervous system depressant. First be excited, and inhibit。Acute poisoning：Acute poisoning proceed from taking orally. Generally speaking, it has four grades adout excitement, hypnogenesis, anesthesia, stifler. If the patient get into the third section or the fourth section，it will loss of consciousness, mydriasis, irregular respiration, shock, mental efforts circulatory collapse and respiratory arrest.Chronic influence：If you contact liquid inside for a long time, may cause eye irritation .It can produce chilling sensation and discomfort. As well as may cause headache, dizzy, tired, temperament, fremitus, queasy and so on.If drink to excess for a long time, may cause polyneuritis ,chronic gastritis, fatty liver, hepatocirrhosis , myocardial damage ,organic psychosis and so on . Also may cause skin irritation. Repeated or prolonged contact may cause skin drying.Toxicology data and behavioral environmentToxicity：Oligodynamic action.Acute toxicity：LD507060mg/kg(rabbit by per os)；7340mg/kg(rabbit by skin)；LC5037620mg/m3，10 hours.( bandicoot breathe in)；breathe in 4.3mg/L50 minutes，head and face pyrexia，Cold horror penetrated，headache； breathe in 2.6mg/L39 minutes，headache，no after-action.Thrill：rabbit by eye ：500mg，high thrill.rabbit openness challenge test by skin：15mg/24 hours，low-grade thrill.Subacute and chronic toxicity：bandicoot by per os :10.2g/(kg？day)，12 weeks，keep slim，fatty liver.Mutagenicity：microbiologic mutation： Salmonella aertrycke is feminine.dominant lethal test：mouse by per os 11.5g/(kg？day),2 weeks, masculine.Reproduction toxicity： bandicoot celiac the lowest toxicant concentration (TDL0)：7.5g/kg(pregnant 9day)，masculine teratogenesis.Carcinogenicity ：mouse by per os lowest poisonous dose (TDL0)：340mg/kg(57week，gap)，cancerogenic masculine.Dangerous characteristic：Flammability，mix smoke and air up with explosive gas mixture.If meet with naked fire and high temperature,it can lead to decrepitation.If meet with oxidizer, may cause chemical reaction or combustion.In the fire，receptacle be heated may cause explosion.The smoke is heavier than air，can spread from substory to distance and can backflash when meet with naked fire.Combustion( decomposition ) product：carbon monoxide、carbon dioxide.scene emergency monitoring method：Gas detector tube method；portable type gas phase chromatographygas velocity detector tube（The product of Beijing Labor Insurance Agency）laboratory procedure：gas phase chromatography-monitor and analytical method for air and steamEdit by State Environmental Protection Administrationgas phase chromatography-Solid Waste Test and Analysis and Evaluation HandbookTranslate by China environmental monitoring terminalpotassium dichromate method-Chemical determination of harmful substances in the airpress by chemical industry environmental standard：Former Soviet Union in workshop atmosphere maximum allowable concentration of hazardous substance 1000mg/m3Former Soviet Union (1977) air quality standard 5.0mg/m3Odor threshold 50ppmaccidental release measuresleakage emergency measuresMove the person who in the contaminated zone to the safety zone quickly，and they should be separated from the others. Come and go in close restraint.Cut off the fire brand。Emergency personnel should wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes.Dont touch the ooze immediately.As far as possible, cut off the leakage point. To prevent it spreading to the sewer and gutter that restricted quarter.small quantity leakiness：Sandy clay or other incombustible material absorbs it. Also can rinse by plentiful water，and put the sewage in wastewater treatment system。large quantity leakiness：Build diking or digging pit to take it inTo cover with foam，and can reduce the damage the smoke had caused。Move it to tank car or interceptor from explosion stack .Transported it to the waste treatment site，and it can be treated or recycled.Preventive measurePreventive respiratory system：Dont need special defend and preserve popularly. If contact with high concentration, you should wear filtermask (half-mask respirator).Eye-protective：Ordinarily, it have no use for especial protection。Physical protection：Wear antistatic work clothes。Hand-protective：Wear protective gloves as general job.Other protect:No Smoking at working site.emergency treatmentSkin exposure：In case of contact , immediately wash skin soap and copious amounts of water .if irritation persists .Call a physician. Eye exposure：In case of contact with eyes ,flush with copious amounts of water for at least 15 minutes .Assure adequate flushing by separating the eyelids with fingers. If irritation persists . Call a physician Inhalation：Remove victim to fresh air and provide oxygen if breathing is difficult. Call a physician。Oral exposure：If swallo
