Section IV.        First Aid Measures    
    Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15
    Eye Contact
    minutes. Get medical attention.
    Skin Contact        In case of contact, immediately flush skin with plenty of water. Remove contaminated clothing and shoes. Wash clothing    
    before reuse. Thoroughly clean shoes before reuse. Get medical attention.
    Inhalation        If the victim is not breathing, perform mouth-to-mouth resuscitation. Loosen tight clothing such as a collar, tie, belt or    
    waistband. If breathing is difficult, oxygen can be administered. Seek medical attention if respiration problems do not
    improve.
    Ingestion        DO NOT INDUCE VOMITING. Loosen tight clothing such as a collar, tie, belt or waistband. If the victim is not breathing,    
    perform mouth-to-mouth resuscitation. Examine the lips and mouth to ascertain whether the tissues are damaged, a possible
    indication that the toxic material was ingested; the absence of such signs, however, is not conclusive.

Section XII.        Ecological Information    
    Not available.
    Ecotoxicity
    Environmental Fate        n-Hexane's production and use as a pure or commercial grade solvent, as a raw material in the synthesis of polyolefins,    
    elastomers and pharmaceuticals, in the formulation of glues, stains, varnishes and other industrial chemicals may result in its
    release to the environment through various waste streams. n-Hexane is also a component of natural gas and crude oil. The
    vast majority of n-hexane is released to the environment through the manufacture, use, and disposal of many products
    associated with the petroleum industry and the combustion of gasoline. If released to air, a vapor pressure of 153 mm Hg at
    25 deg C indicates n-hexane will exist solely as a vapor in the ambient atmosphere. Vapor-phase n-hexane will be degraded
    in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated
    to be 3 days. If released to soil, n-hexane is expected to have high mobility based upon an estimated Koc of 150.
    Volatilization from moist soil surfaces is expected to be an important fate process based upon an estimated Henry's Law
    constant of 1.83 atm-cu m/mole. n-Hexane may volatilize from dry soil surfaces based upon its vapor pressure. Screening
    studies suggest that n-hexane will undergo biodegradation in soil and water surfaces, but volatilization is expected to be the
    predominant fate process in the environment. If released into water, n-hexane is not expected to adsorb to suspended solids
    and sediment based upon the estimated Koc. Volatilization from water surfaces is expected to be an important fate process
    based upon this compound's estimated Henry's Law constant. Estimated volatilization half-lives for a model river and model
    lake are 1 hour and 3 days, respectively. An estimated BCF of 200 suggests the potential for bioconcentration in aquatic
    organisms is high. Hydrolysis is not expected to be an important environmental fate process since this compound lacks
    functional groups that hydrolyze under environmental conditions. Occupational exposure to n-hexane may occur through
    inhalation and dermal contact with this compound at workplaces where n-hexane is produced or used. Monitoring data
    indicate that the general population may be exposed to n-hexane via inhalation of ambient air, particularly at urban areas with
    heavy vehicular traffic or gasoline filling stations.
