Section III. Hazards Identification
    Acute Health Effects        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.
    Harmful if ingested or inhaled. Minimize exposure to this material. Severe overexposure can result in injury or death.
    Skin contact may result in sensitization. Always cover all exposed skin with an impermeable layer and use proper eye
    protection. A OSHA/MSHA approved dust and vapor respirator is required when working with this material.
    Follow safe industrial hygiene practices and always wear proper protective equipment when handling this compound.

    MUTAGENIC EFFECTS : Not available.
    TERATOGENIC EFFECTS : Not available.
    DEVELOPMENTAL TOXICITY: Not available.
    Repeated or prolonged exposure to this compound is not known to aggravate existing medical conditions.

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. Remove contaminated clothing and shoes. Wash clothing
    Skin Contact
    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.

    Handling and Storage
    container and store in a dry, cool place. Avoid excessive heat and light. Do not breathe dust.
    Information
    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. Dust respirator. Lab coat. Boots. Gloves. Suggested protective clothing might not be sufficient; consult a
    Personal Protection
    specialist BEFORE handling this product. Be sure to use a MSHA/NIOSH approved respirator or equivalent.
