Section III. Hazards Identification
    Acute Health Effects        Highly toxic if ingested or inhaled. Avoid prolonged contact with this material. Overexposure may result in serious illness    
    or death. Follow safe industrial hygiene practices and always wear proper protective equipment when handling this
    compound.

    DEVELOPMENTAL TOXICITY: Not available.
    Repeated exposure to an highly toxic material may produce general deterioration of health by an accumulation in one or
    many human organs.

Section IV.        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. 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. COLD water
    may be used. Cover the irritated skin with an emollient. Seek medical attention. Treat symptomatically and supportively.
    Wash any contaminated clothing before reusing.
    Inhalation        Evacuate the victim to a safe area as soon as possible. Loosen tight clothing such as a collar, tie, belt or waistband.    
    WARNING: It may be dangerous to the person providing aid to give mouth-to-mouth resuscitation when the inhaled
    material is toxic, infectious or corrosive. Seek immediate medical attention and, if possible, show the chemical label.
    Treat symptomatically and supportively.
    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, 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 VI.        Accidental Release Measures    
    Spill Cleanup        Highly toxic solid.    
    Instructions        Stop leak if without risk. DO NOT get water inside container. DO NOT touch spilled material. Use water spray to reduce    
    vapors. Prevent entry into sewers, basements or confined areas; dike if needed. Eliminate all sources of ignition.
    Consult federal, state, and/or local authorities for assistance on disposal.

Section VII. Handling and Storage
    Handling and Storage        HIGHLY TOXIC. Handle with caution and minimize exposure. 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
    Information
    light. DO NOT ingest. DO NOT breathe dust. In case of insufficient ventilation, wear suitable respiratory equipment. If
    ingested, seek medical advice immediately and show the container or the label. 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
    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. Boots. Gloves. A MSHA/NIOSH approved respirator must be used to avoid    
    inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist BEFORE handling
    this product.
    Exposure Limits        Not available.
