Section III. Hazards Identification
    Acute Health Effects        Toxic if ingested or inhaled. Avoid prolonged contact with this material. Overexposure may result in serious illness or death.    
    Irritating to eyes and skin on contact. Inhalation causes irritation of the lungs and respiratory system. Inflammation of the
    eye is characterized by redness, watering, and itching. Skin inflammation is characterized by itching, scaling, reddening, or,
    occasionally, blistering.
    Follow safe industrial hygiene practices and always wear proper protective equipment when handling this compound.
    Chronic Health Effects        CARCINOGENIC EFFECTS : Not available.    
    MUTAGENIC EFFECTS : Not available.
    TERATOGENIC EFFECTS : Not available.
    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    
    Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15
    Eye Contact
    minutes. Get medical attention.
    In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing
    Skin Contact
    and shoes. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical attention immediately.
    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.

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.
    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.
