Section IV.First Aid Measures
Eye Contact
Check 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 Contact
After 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.
If the victim is not breathing, perform artificial respiration. Loosen tight clothing such as a collar, tie, belt or waistband. If
Inhalation
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 VI.Accidental Release Measures
Spill CleanupHarmful material. Irritating material.
InstructionsIn case of a spill and/or a leak, always shut off any sources of ignition, ventilate the area, and exercise caution. Use a
shovel to put the material into a convenient waste disposal container. Finish cleaning the spill by rinsing any
contaminated surfaces with copious amounts of water. Consult federal, state, and/or local authorities for assistance on
disposal.

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

---

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.
