Section IV.        First Aid Measures    
    Eye Contact        Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15    
    minutes. Get medical attention.
    Skin Contact        In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing    
    and shoes. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical attention immediately.
    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        INDUCE VOMITING by sticking finger in throat. Lower the head so that the vomit will not reenter the mouth and throat.    
    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        1-Chloro-4-nitrobenzene's production and use as an intermediate in preparing dyes, agricultural and rubber chemicals, may    
    result in its release to the environment through various waste streams. If released to air, a vapor pressure of 0.022 mm Hg at
    25 deg C indicates 1-chloro-4-nitrobenzene will exist solely as a vapor in the atmosphere. Vapor-phase
    1-chloro-4-nitrobenzene 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 94 days. Weak absorption of UV light greater than 290 nm by
    1-chloro-4-nitrobenzene indicates potential for photolysis by sunlight. If released to soil, 1-chloro-4-nitrobenzene is expected
    to have moderate mobility in soil based on an estimated Koc value of 310. Volatilization from dry soil surfaces may occur
    given a Henry's Law constant of 4.9X10-6 atm-cu m/mole. 1-Chloro-4-nitrobenzene is not expected to volatilize from dry soil
    surfaces based upon its vapor pressure. Screening tests using activated sludge, suggest biodegradation of
    1-chloro-4-nitrobenzene proceeds slowly in water and soil. If released into water, 1-chloro-4-nitrobenzene is 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 Henry's Law constant. Estimated volatilization half-lives for a model
    river and model lake are 152 hours and 73 days, respectively. Hydrolysis is not expected to be an important environmental
    fate process since this compound lacks functional groups that hydrolyze under environmental conditions. BCF values of
    5.8-20.9 measured in fish, suggests bioconcentration in aquatic organisms is low. Occupational exposure may occur through
    inhalation and dermal contact with this compound at workplaces where 1-chloro-4-nitrobenzene is produced or used.
