Section IV.        First Aid Measures    
    Eye Contact
    C heck for and rem ove any contact lenses. D O N O T use an eye ointm ent. Flush eyes w ith running w ater for a m inim um
    of 15 m inutes, occasionally lifting the upper and low er eyelids. Seek m edical attention. Treat sym ptom atically and
    supportively.
    Skin Contact
    A fter contact w ith skin, w ash im m ediately w ith plen ty of w ater. G ently and thoroughly w ash the contam inated skin w ith
    running w ater and non-abrasive soap. Be particularly careful to clean folds, crevices, creases and groin. C over the
    irritated skin w ith an em ollient. Seek m edical attention. Treat sym ptom atically and supportively. W ash 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 w aistband.
    If breathing is difficult, oxygen can be administered. Seek medical attention. Treat symptomatically and supportively.
    Ingestion
    D O N O T induce vom iting. Loosen tight clothing such as a collar, tie, belt, or w aistband. If the victim is not breathing,
    adm inister artificial respiration. Exam ine the lips and m outh to ascertain w hether the tissues are dam aged, a possible
    indication that the toxic m aterial w as ingested; th e absence of such signs, how ever, is not conclusive. Seek im m ediate
    medical attention and, if possible, show the chemical label. Treat symptomatically and supportively.
