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

    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 VII. Handling and Storage
    Keep away from heat and sources of ignition. Mechanical exhaust required. When not in use, tightly seal the container and
    Handling and Storage
    store in a dry, cool place. Avoid excessive heat and light. DO NOT breathe dust. In case of insufficient ventilation, wear
    Information
    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 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
