Section III. Hazards Identification
    Acute Health Effects        Corrosive to eyes and skin. The amount of tissue damage depends on length of contact. Eye contact can result in corneal    
    damage or blindness. Skin contact can produce inflammation and blistering. Inhalation of dust will produce irritation to
    gastro-intestinal or respiratory tract, characterized by burning, sneezing and coughing. Severe over-exposure can produce
    lung damage, choking, unconsciousness or death.
    Harmful if ingested or inhaled. Minimize exposure to this material. Severe overexposure can result in injury or death.
    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 of the eyes to a low level of dust can produce eye irritation. Repeated skin exposure can produce local
    skin destruction, or dermatitis. Repeated inhalation of dust can produce varying degree of respiratory irritation or lung
    damage.

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.
    If the victim is not breathing, perform mouth-to-mouth resuscitation. Loosen tight clothing such as a collar, tie, belt or
    Inhalation
    waistband. If breathing is difficult, oxygen can be administered. Seek medical attention if respiration problems do not
    improve.
    Ingestion        DO NOT INDUCE VOMITING. 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.
