Section IV.First Aid Measures
Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15
Eye Contact
minutes. Get medical attention.
In case of contact, immediately flush skin with plenty of water. Remove contaminated clothing and shoes. Wash clothing
Skin Contact
before reuse. Thoroughly clean shoes before reuse. Get medical attention.
If 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.
IngestionINDUCE VOMITING by sticking finger in throat. Lower the head so that the vomit will not reenter the mouth and throat.
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.
