Section IV.        First Aid Measures    
    Eye Contact        Check for and remove any contact lenses. DO NOT use an eye ointment. Flush eyes with running water for a minimum    
    of 15 minutes, occasionally lifting the upper and lower eyelids. Seek medical attention. Treat symptomatically and
    supportively.
    Skin Contact        After contact with skin, wash immediately with plenty of water. Gently and thoroughly wash the contaminated skin with    
    running water and non-abrasive 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.
    Evacuate the victim to a safe area as soon as possible. Loosen tight clothing such as a collar, tie, belt or waistband. If
    Inhalation
    breathing is difficult, administer oxygen. If the victim is not breathing, perform artificial respiration. WARNING: It may be
    dangerous to the person providing aid to give mouth-to-mouth resuscitation when the inhaled material is toxic, infectious
    or corrosive. 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.
