Section IV.        First Aid Measures    
    Eye Contact
    C heck for and rem ove any contact lenses. In case of contact, im m ediately flush eyes w ith plenty of w ater for at least 15
    minutes. Get medical attention.
    Skin Contact
    In case of contact, im m ediately flush skin w ith plenty of w ater. Rem ove contam inated clothing and shoes. W ash
    clothing before reuse. Thoroughly clean shoes before reuse. Get medical attention.
    Inhalation
    If the victim is not breathing, perform m outh-to-m outh resuscitation. Loosen tight clothing such as a collar, tie, belt or
    w aistband. If breathing is difficult, oxygen can be adm inistered. Seek m edical attention if respiration problem s do not
    improve.
    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, perform m outh-to-m outh
    resuscitation. Exam ine the lips and m outh to ascertain w hether the tissues are dam aged, a possible in dication that the
    toxic material was ingested; the absence of such signs, however, is not conclusive.
