Material Safety Data Sheet of Ethanol

    Material Safety Data Sheet of Ethanol 1. Physical and Chemical Properties

    Chemical Name: Ethanol

    Alternative name: Ethyl Alcohol

    Molecular Formula: C2H6OCH3CH2OH

    Molecular Weight: 46.07

    Melting Point: -90?

    Boiling Point: 78.3?

    Density/ Specific Gravity: 0.79 (water=1)

    Vapor Pressure: 12?

    Solubility: Soluble in water and most organic solvent including ether, chloroform, glycerin

    Chemical Stability: Stable

    Appearance and Physical State: clear colorless Liquid, with aromatic odor

    Risk Classification: 7 (flammable liquid)

    Application: alcohol drinks industry, organic synthesis, use as solvent of sanitizer

2. Environmental Information

    1. Potential Health Hazards

    Effects health via: ingestion, inhalation, skin contact.

    Hazards: causes central nervous system depression. First characterized by

    excitement, followed by depression.

    Acute toxicosis: Mostly because been swallowed. Normally there are four stages

    as excitement, drownsiness, coma and respiratory failure. Third and forth stages

    may cause unconsciousness, collapse, coma, then death due to angiocarpy and

    respiratory failure.

    Chronic: Prolonged exposure to high concentrations may cause irritation to eyes

    and respiratory tract. May cause nervous system effects characterized by headache,

    dizziness, unconsciousness coma and nausea, also causes liver and alimentary

    tract damage Prolonged or repeated skin contact may cause defatting and

    dermatitis.

    2. Toxicological and Environmental Information

    Toxicity: tiny toxic

    Acute Toxicity:

    Oral, Rabbit: LD50 7060mg/kg

     Skin, Rabbit: LD50 7340mg/kg

    2Inhalation, Rat: LC50 37620mg/m/10H

    Draize test, rabbit, eye: 500 mg Severe;

    Draize test, rabbit, skin: 15 mg/24H Moderate;

    Subacute and chronic: Oral, Rat:10.2g/kg/day, 12 weeks, lost weight, with fatty liver

    Mutagenicity

    Reproductive toxicity Oral, Rat TDLo7.5g/kg(9days pregnant)teratogenicity

    positive.

    Carcinogenicity Oral, Mouse TDLo340mg/kg (57weeksdiscontinuous)

    carcinogenicity positive.

    Fire Risk: Flammable liquid and vapor. Vapors may form an explosive mixture with air. Containers may explode in the heat of a fire. May form explosive peroxides. Vapors may be heavier than air. They can spread along the ground and collect in low or confined areas. Also may travel to a source of ignition and flash back.

    Decomposition Products: Carbon monoxide, carbon dioxide.

    3. Emergency Monitoring

    Gas detector tube; Portable gas chromatography

    Fast gas detecting tube

    4. Lab. Monitoring

    Gas chromatography <Air/ waste gas monitoring and analysis> (China

    National Environmental Protection Bureau)

    Gas chromatography <Evaluation manual of solids waste testing and analysis>

    (China National Environmental Monitoring Centre)

    potassium dichromate method< testing methods of chemical enterprise

    harmfulgasandvapo emission>(Chemical Industry Press)

    5. Environmental standard

    Former Soviet Union Standard: Max. concentration of harmful substance in air in

    3workshop below 1000mg/m.

    3Former Soviet Union Standard(1977): Atmosphere quality standard0.5mg/m.

    Olfaction threshold concentration 50ppm.

    6. Emergency measures

    a. Accidental release measures

    Evaluate everyone to safe place, away from spilling and leaking. Remove

    all sources of ignition. For emergency or engineering handling, wear a

    self-contained breathing apparatus in pressure-demand, and full protective

    gear. Absorb spill with inert material (e.g. vermiculite, sand or earth), then

    place in suitable container. A vapor suppressing foam may be used to

    reduce vapors.

    b. Personal Protective Equipment

    Respiratory tract: need not particular protection, to avoid inhalation of

    high concentrations, wear a filtering respirator or chemical safety goggles.

    Eyes: need not particular protection.

    Clothing: anti-static workwear.

    Skin(hands): wear regular protective gloves to prevent skin exposure.

    Additional: no smoking during handling process or in storage c. First Aid Measures

    Skin contact: remove contaminated clothing and shoes, flush skin with plenty of water.

    Eye contact: lifting the upper and lower eyelids. flush eyes with plenty of water or physiological saline .Get medical aid immediately.

    Inhalation: Remove from exposure to fresh air immediately. Get medical aid immediately.

    Ingestion: give enough warm water, and induce vomiting. Get medical aid. d. Fire Fighting Measures: move more containers to safe places if possible. Use water spray to cool fire-exposed containers until well after fire is out. Extinguishing Media: dry chemical, alcohol-resistant foam, carbon dioxide, sand.
