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. 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. 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.
