Section IV.First Aid Measures
Eye ContactCheck for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15
minutes. Get medical attention.
Skin ContactIn case of contact, immediately flush skin with plenty of water. Remove contaminated clothing and shoes. Wash clothing
before reuse. Thoroughly clean shoes before reuse. Get medical attention.
InhalationIf the victim is not breathing, perform mouth-to-mouth resuscitation. Loosen tight clothing such as a collar, tie, belt or
waistband. If breathing is difficult, oxygen can be administered. Seek medical attention if respiration problems do not
improve.
INDUCE VOMITING by sticking finger in throat. Lower the head so that the vomit will not reenter the mouth and throat.
Ingestion
Loosen tight clothing such as a collar, tie, belt or waistband. If the victim is not breathing, perform mouth-to-mouth
resuscitation. 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.
