Section 4. 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. Seek medical attention.
    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.
    Cold water may be used. Cover the irritated skin with an emollient. If irritation persists, seek medical attention.
    Wash contaminated clothing before reusing.
    Serious Skin Contact        Not available.    
    Inhalation        Allow the victim to rest in a well ventilated area. Seek immediate medical attention.    
    Serious Inhalation        Evacuate the victim to a safe area as soon as possible. Loosen tight clothing such as a collar, tie, belt or    
    waistband. If breathing is difficult, administer oxygen. If the victim is not breathing, perform mouth-to-mouth
    resuscitation. Seek medical attention.
    Ingestion        Do not induce vomiting. 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. Loosen
    tight clothing such as a collar, tie, belt or waistband. If the victim is not breathing, perform mouth-to-mouth
    resuscitation. Seek immediate medical attention.

    closed. Keep in a cool, well-ventilated place. Highly toxic or infectious materials should be stored in a separate
    locked safety storage cabinet or room.

Section 8. 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. Be sure to use an approved/certified respirator or equivalent.    
    Personal Protection in Case of Splash goggles. Full suit. Dust respirator. Boots. Gloves. A self contained breathing apparatus should be used
    a Large Spill        to avoid inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist    
    BEFORE handling this product.
