Section IV.        First Aid Measures    
    Eye Contact        Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15    
    minutes. Get medical attention.
    Skin Contact        In case of contact, immediately flush skin with plenty of water. Remove contaminated clothing and shoes. Wash clothing    
    before reuse. Thoroughly clean shoes before reuse. Get medical attention.
    Inhalation        If the victim is not breathing, perform mouth-to-mouth resuscitation. Loosen tight clothing such as a collar, tie, belt or    
    waistband. If breathing is difficult, oxygen can be administered. Seek medical attention if respiration problems do not
    improve.
    Ingestion        INDUCE VOMITING by sticking finger in throat. Lower the head so that the vomit will not reenter the mouth and throat.    
    Loosen tight clothing such as a collar, tie, belt or waistband. If the victim is not breathing, perform mouth-to-mouth
    resuscitation. 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 in case of ingestion of a radioactive material.

Section VII. Handling and Storage
    Handling and Storage        FLAMMABLE. Keep away from heat. Mechanical exhaust required. Avoid excessive heat and light. Do not breathe    
    gas/fumes/ vapor/spray.
    Information
    Always store away from incompatible compounds such as oxidizing agents. Reactive with strong oxidizers; may be
    ignited by heat, sparks or flames. Vapors may travel to source of ignition and flash back. 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. Handle with caution and minimize exposure. Keep away from heat and sources of
    ignition. Tightly seal container and store in a cool, dry place. Use only non-sparking hand tool when handling this
    product.

Section VIII. Exposure Controls/Personal Protection
    Engineering Controls        Provide exhaust ventilation or other engineering controls to keep the airborne concentrations of vapors below their    
    respective threshold limit value. Ensure that eyewash station and safety shower is proximal to the work-station location.
    Personal Protection        Splash goggles. Lab coat. Vapor respirator. Boots. Gloves. Be sure to use a MSHA/NIOSH approved respirator or    
    equivalent. Suggested protective clothing might not be sufficient; consult a specialist BEFORE handling this product.
