Ethanol is a flammable liquid whose vapor can form a flammable and explosive mixture with air at normal room temperature. Thus, an aqueous mixture containing 30% ethanol can produce a flammable mixture of vapor and air at 290C, and even an aqueous mixture containing only 5% ethanol can produce a flammable mixture at 620C. 1 Ethanol reacts violently with a variety of oxidizing materials and other substances. Chemicals 2 such as disulfide difluoride, silver nitrate, bromine pentafluoride, potassium perchlorate, nitrosyl perchlorate, chloryl chloride, chloryl tetrachloride, uranyl perchlorate, chromium trioxide, fluorine nitrate , oxygen difluoride, uranium hexafluoride, iodine heptafluoride, tetrachlorosilane, permanganic acid, nitric acid [nitric acid] The hissing reaction officially used for cleaning laboratory glassware should not be used3,5], peroxidation Hydrogen, peroxodisulfate, potassium dioxide, sodium peroxide, potassium permanganate, ruthenium(VIII) oxide, platinum, potassium 6, potassium tert-butoxide, silver oxide and sodium 7.
: Ethanol is rapidly oxidized in the body to acetaldehyde, then to acetic acid, and finally to carbon dioxide and water; unoxidized alcohol is excreted through urine and exhaled in the air. 8, 9
: Some evidence of fetal toxicity 26 – 28 and teratogenicity 29 has been observed in experimental animals
High-dose ethanol treatment during pregnancy. Alcohol may cause miscarriage, may impair fertility, may cause harm to the unborn child, and may cause harm to a breastfed baby. Reproductive harm has been identified following repeated excessive ingestion of ethanol; these effects are unlikely to occur through exposure below the occupational exposure limits in the work environment.
: Somewhat irritating ethanol msds . Exposure to liquids, vapors, fumes or mists may cause irritation. Direct contact may cause irritation, redness, pain, corneal inflammation, and possible corneal damage.
: Repeated or prolonged contact may cause degreasing, redness, pain, itching, inflammation, cracking and possible secondary infection. Repeated skin contact may cause an allergic skin reaction in a rare number of people.
Large doses can cause alcohol poisoning, and repeated ingestion can lead to alcohol poisoning. Alcohol abuse and dependence can have profound effects on work performance and the likelihood of workplace accidents. 11-13 Presence of denaturing agents, such as alcohol. The methanol, pyridine and benzene in industrial alcohol greatly increase the toxicity after ingestion. Drinking ethanol is also suspected of inhibiting the metabolism or excretion of other chemicals in laboratories and workplaces, thereby increasing their toxic effects14; e.g. 1, 1, 1
– Trichloroethane15, xylene, trichloroethylene and dimethylformamide16, benzene17 and lead. 18,19 May cause harmful effects on the central nervous system. Effects may include euphoria, headache, dizziness, drowsiness, blurred vision, fatigue, tremors, convulsions, loss of consciousness, coma, respiratory arrest, and death. Severe acute intoxication may result in hypoglycemia, hypothermia, and extensor rigidity. Prolonged or frequent exposure may cause liver damage.
