Section IV.        First Aid Measures    
    Eye Contact
    C heck for and rem ove any contact lenses. IM M ED IA TELY flush eyes w ith running w ater for at least 15 m inutes, keeping
    eyelids open. C O LD w ater m ay be used. D O N O T use an eye oitm ent. Flush eyes w ith running w ater for a m inim um of 15
    minutes, occasionally lifting the upper and lower eyelids. Seek medical attention. Treat symptomatically and supportively.
    Skin Contact
    If the chem ical gets spilled on a clothed portion of the body, rem ove the contam inated clothes as quickly as possible,
    protectin g you r h an ds an d body. Place th e victim u n der a delu g e sh ow er. If th e ch em ical tou ch es th e victim 's exposed

    Be particularly careful to clean folds, crevices, creases and groin. Seek m edical attention. Treat sym ptom atically 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 w aistband.
    If breathing is difficult, oxygen can be administered. Seek medical attention. Treat symptomatically and supportively.
    Ingestion
    IN D U C E V O M ITIN G by sticking finger in throat. Low er the head so that the vom it w ill not reenter the m outh and throat.
    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; the absence of such signs, how ever, is not conclusive. Seek im m ediate m edical attention
    and, if possible, show the chemical label. Treat symptomatically and supportively.
