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.
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, 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.

Section VIII. Exposure Controls/Personal Protection
Engineering ControlsUse process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended
exposure limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to airborne contaminants
below the exposure limit.
Personal ProtectionSplash goggles. Lab coat. Dust respirator. Boots. Gloves. A MSHA/NIOSH approved respirator must be used to avoid
inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist BEFORE handling this
product.
