    a carcinogen.
    This compound is classified as
    a possible mutagen. There is
    no acceptable exposure limit for
    a mutagen.

Section III. Hazards Identification
    Toxic if ingested or inhaled. Avoid prolonged contact with this material. Overexposure may result in serious illness or death.
    Acute Health Effects
    Corrosive to skin, eyes, and respiratory system. Liquid or spray mist may produce tissue damage, particularly in mucous
    membranes of the eyes, mouth and respiratory tract. Skin contact may produce burns. Eye contact can result in corneal
    damage or blindness. Inhalation of the spray mist may produce severe irritation of respiratory tract, characterized by
    coughing, choking, or shortness of breath. Corrosive materials may cause serious injury if ingested.
    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.
    CARCINOGENIC EFFECTS : Not available.
    Chronic Health Effects
    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. 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

    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        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.
