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.
    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
    Handling and Storage        FLAMMABLE SOLID. MAY REACT VIOLENTLY AND/OR EVOLVE HEAT UPON EXPOSURE TO SHOCK, HEAT, AND    
    FRICTION. Reactive with strong oxidizers; may be ignited by heat, sparks, or flames. Vapors may travel to source of
    Information
    ignition and flash back. Tightly seal container and store in a cool place. Closed containers may explode from heat of a fire.
    Empty containers may pose a fire risk. Evaporate residue under a fume hood if possible. Ground all equipment containing
    material. Keep away from heat and sources of ignition. Mechanical exhaust required. When not in use, tightly seal the
    container and store in a dry, cool place. Avoid excessive heat and light. 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.
    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
    Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended
    Engineering Controls
    exposure limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to airborne contaminants
    below the exposure limit.
    Splash goggles. Lab coat. Dust respirator. Boots. Gloves. A MSHA/NIOSH approved respirator must be used to avoid
    Personal Protection
    inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist BEFORE handling this
    product.
