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.
