    soap. Be particularly careful to clean folds, crevices, creases and groin. Cover the irritated skin with an emollient. Seek
    medical attention. Treat symptomatically and supportively. Wash any contaminated clothing before reusing.
    Inhalation        If the victim is not breathing, perform artificial respiration. Loosen tight clothing such as a collar, tie, belt or waistband. If    
    breathing is difficult, oxygen can be administered. Seek medical attention. Treat symptomatically and supportively.
    Remove dentures if any. Have conscious person drink several glasses of water or milk. INDUCE VOMITING by sticking
    Ingestion
    finger in throat. Lower the head so that the vomit will not reenter the mouth and throat. NEVER give an unconscious
    person anything to ingest. Seek medical attention. Treat symptomatically and supportively.

Section XII.        Ecological Information    
    Ecotoxicity        Not available.    
    2-Isopropylnaphthalene is a component of crude oil and a product of combustion which is produced and released to the
    Environmental Fate
    environment during natural fires. Emissions from petroleum refining, coal tar distillation, and gasoline and diesel fueled
    engines are contributors of 2-isopropylnaphthalene to the environment. 2-Isopropylnaphthalene is also used as chemical
    intermediate and a general solvent. Consequently, 2-isopropylnaphthalene is released to the environment via
    manufacturing effluents. 2-Isopropylnaphthalene is also released to the environment by municipal waste incinerators.
    2-Isopropylnaphthalene should biodegrade in the environment. However, hydrolysis of 2-isopropylnaphthalene should not
    be important. In sunlit environmental media, 2-isopropylnaphthalene will undergo direct photolysis. 2-Isopropylnaphthalene
    is expected to be slightly mobile to immobile in soil. 2-Isopropylnaphthalene has the potential to bioconcentrate in aquatic
    organisms. 2-Isopropylnaphthalene may also partition from the water column to organic matter contained in sediments
    and suspended solids. Volatilization of 2-isopropylnaphthalene from environmental waters may be important. The
    volatilization half-lives from a model river and a model pond, the latter considers the effect of adsorption, have been
    estimated to be 5.2 hr and 93.6 days, respectively. 2-Isopropylnaphthalene is expected to exist entirely in the vapor phase
    in ambient air. In the atmosphere, reaction with photochemically produced hydroxyl radicals (half-life of 6.6 hr) is likely to
    be important. The most probable human exposure would be occupational exposure, which may occur through dermal
    contact or inhalation at places were 2-isopropylnaphthalene is produced or used. Non-occupational exposures would most
    likely occur via urban atmospheres, contaminated drinking water supplies and recreational activities at contaminated
    waterways. (Excerpted from HSDB, 1996)

Section XIII. Disposal Considerations
    Waste Disposal        Recycle to process, if possible. Consult your local or regional authorities. You may be able to dissolve or mix material with    
    a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber system. Observe all
    federal, state, and local regulations when disposing of this substance.
