Section IV.First Aid Measures
Eye ContactCheck for and remove any contact lenses. DO NOT use an eye ointment. Flush eyes with running water for a minimum
of 15 minutes, occasionally lifting the upper and lower eyelids. Seek medical attention. Treat symptomatically and
supportively.
Skin ContactIf the chemical gets spilled on a clothed portion of the body, remove the contaminated clothes as quickly as possible,
protecting your own hands and body. Place the victim under a deluge shower. If the chemical touches the victim's
exposed skin, such as the hands: Gently and thoroughly wash the contaminated skin with running water and non-abrasive
soap. Be particularly careful to clean folds, crevices, creases and groin. Cover the irritated skin with an emollient. Seek
medical attention. Treat symptomatically and supportively. Wash any contaminated clothing before reusing.
InhalationIf the victim is not breathing, perform artificial respiration. Loosen tight clothing such as a collar, tie, belt or waistband. If
breathing is difficult, oxygen can be administered. Seek medical attention. Treat symptomatically and supportively.
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, administer artificial respiration.
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. Seek immediate medical attention and, if possible,
show the chemical label. Treat symptomatically and supportively.
