Section 7. Handling and Storage
    Precautions        Keep away from heat. Keep away from sources of ignition. Empty containers pose a fire risk, evaporate the    
    residue under a fume hood. Ground all equipment containing material. Do not breathe dust. In case of
    insufficient ventilation, wear suitable respiratory equipment If you feel unwell, seek medical attention and show the
    label when possible. Avoid contact with skin and eyes
    Storage        Keep container dry. Keep in a cool place. Ground all equipment containing material. Keep container tightly    
    closed. Keep in a cool, well-ventilated place. Combustible materials should be stored away from extreme heat
    and away from strong oxidizing agents.

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.    
    Gloves.
    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.
