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 ContactAfter contact with skin, wash immediately with plenty of water. 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.

Section VII. Handling and Storage
Handling and StorageKeep away from heat and sources of ignition. Mechanical exhaust required. When not in use, tightly seal the container
and store in a dry, cool place. Avoid excessive heat and light. DO NOT breathe dust. In case of insufficient ventilation,
Information
wear suitable respiratory equipment. If you feel unwell, seek medical attention and show the label when possible. Treat
symptomatically and supportively. Avoid contact with skin and eyes.
Always store away from incompatible compounds such as oxidizing agents.

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.
