Section III. Hazards Identification
    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. 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 : Tumorogenic: rat (inhalation) 1800ppm/6H/2 years intertmittent.
    Tumorogenic- Equivocal tumorogenic by RTECS criteria.
    mouse (inhalation) 1800ppm/6H/2 years intermittent.
    Tumorogenic- Carcinogenic by RTECS criteria.
    DEVELOPMENTAL TOXICITY: Reproductive: rat (inhalation) 5000ppm/6H. Duration: female 6-19 days of pregnancy.
    Effects on embryo or fetus- Fetotoxicity.
    mouse (inhalation) 1800ppm/6H. Duration: female 6-17 days of pregnancy.
    Effects on fertility- Post-implantation moratality.
    Repeated or prolonged contact with spray mist may produce chronic eye irritation and severe skin irritation. Repeated or
    prolonged exposure to spray mist may produce respiratory tract irritation leading to frequent attacks of bronchial
    infection.

Section IV.        First Aid Measures    
    Eye Contact        Check for and remove any contact lenses. 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        If the chemical gets spilled on a clothed portion of the body, remove the contaminated clothes as quickly as possible,    
    protecting your own hands and body. Place the victim under a deluge shower. If the chemical touches the victim's
    exposed skin, such as the hands: Gently and thoroughly wash the contaminated skin with running water and non-abrasive
    soap. Be particularly careful to clean folds, crevices, creases and groin. 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. If    
    breathing is difficult, administer oxygen. If the victim is not breathing, perform artificial respiration. 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        DO NOT induce vomiting. 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.
