Section IV.        First Aid Measures    
    Eye Contact        Check for and remove any contact lenses. IMMEDIATELY flush eyes with runing water for at least 15 minutes. keeping    
    eyelids open. COLD water may be used. DO NOT use an eye oitment. Flush eyes with running water for a minimum of
    15 minutes, occasionally lifting the upper eyelids. Seek medical attention. Treat symptomatically and supportively.
    Skin Contact        After contact with skin, wash immediately with plenty of water. Gently and thorough wash the contaminated skin with    
    running water and non-abrasive soap. Be particularly careful to clean folds, crevices, creases and groin. COLD water
    may be used. 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.
    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, administer artificial respiration.
    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. Seek immediate medical attention and, if possible,
    show the chemical label. Treat symptomatically and supportively.
