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,

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.
