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    
    Ecotoxicity        Not available.    
    Environmental Fate        (1,2-Dibromo-3-chloropropane)    
    Due to the restrictions on the use of 1,2-dibromo-3-chloropropane as a nematocide and soil fumigant, little release of
    1,2-dibromo-3-chloropropane presently occurs. The use of 1,2-dibromo-3-chloropropane as a laboratory reactant is not
    expected to result in large quantities being released to the environment. If released to the atmosphere,
    1,2-dibromo-3-chloropropane will exist solely in the vapor phase in the ambient atmosphere, based on a measured vapor
    pressure of 0.58 mm Hg at 20 deg C. Vapor-phase 1,2-dibromo-3-chloropropane is degraded in the atmosphere by reaction
    with photochemically-produced hydroxyl radicals with an estimated half-life of about 37 days. Products of
    1,2-dibromopropanol, chlorobromopropanol, and 1-bromo-3-chloro-2-propanone are formed during this process.
    1,2-Dibromo-3-chloropropane released to soil will likely volatilize or leach. In alkaline, but not neutral or acidic soils, hydrolysis
    may be significant. Biodegradation is possible but is expected to be slow relative to volatilization and leaching. In water,
    1,2-dibromo-3-chloropropane is expected to volatilize. It may also slowly hydrolyze (half-life= 38 years, neutral pH, at 25 deg
    C). Estimated volatilization half-lives for a model river and model lake are 14 hours and 9 days, respectively. In groundwater,
    1,2-dibromo-3-chloropropane is expected to persist due to its low estimated rate of hydrolysis (half-life= 141 years, neutral pH,
    at 15 deg C). In surface waters, biodegradation may occur, but is expected to be slow relative to the rate of volatilization.
    Photodegradation is not expected to be an important fate process for this compound. Sorption to sediments and
    bioconcentration are not expected to be important fate processes based on measured Koc values of 40-149 and measured
    BCF values of 3.6-19, respectively. Human exposure is expected to result primarily from ingestion of drinking water,
    particularly from groundwater sources, containing 1,2-dibromo-3-chloropropane. Occupational exposure to
    1,2-dibromo-3-chloropropane is likely via inhalation and dermal contact with vapors, water, and products containing
    1,2-dibromo-3-chloro-propane.
    (Methanol)
    Methanol’s production and use as a solvent, fuel additive, and in the production of formaldehyde, acetic acid, and methyl
    tertiary butyl ether (MTBE) may result in its release to the environment through various waste streams. Methanol has been
    identified as a natural emission product from various plants and as a biological decomposition product of biological wastes
    and sewage. If released to the atmosphere, a vapor pressure of 127 mm Hg at 25 deg C indicates that methanol will exist
    solely in the vapor phase. Vapor phase methanol is degraded in the atmosphere by reaction with photochemically-produced
    hydroxyl radicals; the half-life for this reaction in air is estimated to be 17 days. If released to soil, methanol is expected to
    have very high mobility based upon an estimated Koc of 1. Volatilization from moist soil surfaces is expected to be an
    important fate process based upon a Henry’s Law constant of 4.55X10-6 atm-cu m/mole. Methanol may also volatilize from
    dry soils based upon it vapor pressure. Biodegradation of methanol in soils is expected to occur rapidly based on half-lives in
    a sandy silt loam from Texas and a sandy loam from Mississippi of 1 and 3.2 days, respectively. If released into water,
    methanol 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 Henry’s Law constant. Estimated
    volatilization half-lives for a model river and model lake are 3 and 35 days, respectively. Biodegradation is expected to occur
    in natural waters since methanol is degraded quickly in soils and was biodegraded rapidly in various aqueous screening tests
    using sewage seed or activated sludge. BCF values of less than 10, measured in fish suggests bioconcentration in aquatic
    organisms is low. Hydrolysis of methanol and photolysis in sunlit surface waters are not expected since methanol lacks
    functional groups that are susceptible to hydrolysis or photolysis under environmental conditions. Occupational exposure to
    methanol may occur through inhalation and dermal contact with this compound at workplaces where methanol is produced or
    used. Monitoring data indicate that the general population may be exposed to methanol via inhalation of ambient air, and
    ingestion of food and drinking water.
