Section IV.        First Aid Measures    
    Eye Contact        Check for and remove any contact lenses. IMMEDIATELY flush eyes with running water for at least 15 minutes, keeping    
    eyelids open. COLD water may be used. 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        If 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. COLD water may be used. Cover the irritated
    skin with an emollient. Seek medical attention. Treat symptomatically and supportively. Wash any contaminated clothing
    before reusing.
    Inhalation        If 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 VI.        Accidental Release Measures    
    Spill Cleanup        Irritating material.    
    In case of a spill and/or a leak, always shut off any sources of ignition, ventilate the area, and exercise caution. Use a
    Instructions
    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
    Handling and Storage        IRRITANT. Keep 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 ingest. DO NOT breathe dust. In case
    Information
    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.

---

Section VIII. Exposure Controls/Personal Protection
    Engineering Controls        Use 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 Protection        Splash 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.
