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 ingest. Do not breathe dust.
    Avoid contact with eyes. Wear suitable protective clothing. In case of insufficient ventilation, wear suitable
    respiratory equipment. If ingested, seek medical advice immediately and show the container or the label.
    Storage        Keep container tightly closed. Keep container in a cool, well-ventilated area.

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.
    Personal Protection in Case of Splash goggles. Full suit. Boots. Gloves. Suggested protective clothing might not be sufficient; consult a
