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.
    Ingestion        INDUCE 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
    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 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.
    Exposure Limits
